The Maya civilization (/ˈmə/) was a Mesoamerican civilization developed by the Maya peoples, and noted for its logosyllabic script—the most sophisticated and highly developed writing system in pre-Columbian Americas—as well as for its art, architecture, mathematics, calendar, and astronomical system. The Maya civilization developed in the area that today comprises southeastern Mexico, all of Guatemala and Belize, and the western portions of Honduras and El Salvador. It includes the northern lowlands of the Yucatán Peninsula and the highlands of the Sierra Madre, the Mexican state of Chiapas, southern Guatemala, El Salvador, and the southern lowlands of the Pacific littoral plain. "Maya" is a modern term used to refer collectively to the various peoples that inhabited this area. They did not call themselves "Maya" and did not have a sense of common identity or political unity. Today, their descendants, known collectively as the Maya, number well over 6 million individuals, speak more than twenty-eight surviving Mayan languages, and reside in nearly the same area as their ancestors.

The Archaic period, before 2000 BC, saw the first developments in agriculture and the earliest villages. The Preclassic period (c. 2000 BC to 250 AD) saw the establishment of the first complex societies in the Maya region, and the cultivation of the staple crops of the Maya diet, including maize, beans, squashes, and chili peppers. The first Maya cities developed around 750 BC, and by 500 BC these cities possessed monumental architecture, including large temples with elaborate stucco façades. Hieroglyphic writing was being used in the Maya region by the 3rd century BC. In the Late Preclassic a number of large cities developed in the Petén Basin, and the city of Kaminaljuyu rose to prominence in the Guatemalan Highlands. Beginning around 250 AD, the Classic period is largely defined as when the Maya were raising sculpted monuments with Long Count dates. This period saw the Maya civilization develop many city-states linked by a complex trade network. In the Maya Lowlands two great rivals, the cities of Tikal and Calakmul, became powerful. The Classic period also saw the intrusive intervention of the central Mexican city of Teotihuacan in Maya dynastic politics. In the 9th century, there was a widespread political collapse in the central Maya region, resulting in internecine warfare, the abandonment of cities, and a northward shift of population. The Postclassic period saw the rise of Chichen Itza in the north, and the expansion of the aggressive Kʼicheʼ kingdom in the Guatemalan Highlands. In the 16th century, the Spanish Empire colonised the Mesoamerican region, and a lengthy series of campaigns saw the fall of Nojpetén, the last Maya city, in 1697.

Rule during the Classic period centred on the concept of the "divine king", who was thought to act as a mediator between mortals and the supernatural realm. Kingship was patrilineal, and power normally passed to the eldest son. A prospective king was expected to be a successful war leader as well as a ruler. Closed patronage systems were the dominant force in Maya politics, although how patronage affected the political makeup of a kingdom varied from city-state to city-state. By the Late Classic period, the aristocracy had grown in size, reducing the previously exclusive power of the king. The Maya developed sophisticated art forms using both perishable and non-perishable materials, including wood, jade, obsidian, ceramics, sculpted stone monuments, stucco, and finely painted murals.

Maya cities tended to expand organically. The city centers comprised ceremonial and administrative complexes, surrounded by an irregularly shaped sprawl of residential districts. Different parts of a city were often linked by causeways. Architecturally, city buildings included palaces, pyramid-temples, ceremonial ballcourts, and structures specially aligned for astronomical observation. The Maya elite were literate, and developed a complex system of hieroglyphic writing. Theirs was the most advanced writing system in the pre-Columbian Americas. The Maya recorded their history and ritual knowledge in screenfold books, of which only three uncontested examples remain, the rest having been destroyed by the Spanish. In addition, a great many examples of Maya texts can be found on stelae and ceramics. The Maya developed a highly complex series of interlocking ritual calendars, and employed mathematics that included one of the earliest known instances of the explicit zero in human history. As a part of their religion, the Maya practised human sacrifice.

The Maya civilization developed within the Mesoamerican cultural area, which covers a region that spreads from northern Mexico southwards into Central America. Mesoamerica was one of six cradles of civilization worldwide. The Mesoamerican area gave rise to a series of cultural developments that included complex societies, agriculture, cities, monumental architecture, writing, and calendrical systems. The set of traits shared by Mesoamerican cultures also included astronomical knowledge, blood and human sacrifice, and a cosmovision that viewed the world as divided into four divisions aligned with the cardinal directions, each with different attributes, and a three-way division of the world into the celestial realm, the earth, and the underworld.

By 6000 BC, the early inhabitants of Mesoamerica were experimenting with the domestication of plants, a process that eventually led to the establishment of sedentary agricultural societies. The diverse climate allowed for wide variation in available crops, but all regions of Mesoamerica cultivated the base crops of maize, beans, and squashes. All Mesoamerican cultures used Stone Age technology; after c. 1000 AD copper, silver and gold were worked. Mesoamerica lacked draft animals, did not use the wheel, and possessed few domesticated animals; the principal means of transport was on foot or by canoe. Mesoamericans viewed the world as hostile and governed by unpredictable deities. The ritual Mesoamerican ballgame was widely played. Mesoamerica is linguistically diverse, with most languages falling within a small number of language families—the major families are Mayan, Mixe–Zoquean, Otomanguean, and Uto-Aztecan; there are also a number of smaller families and isolates. The Mesoamerican language area shares a number of important features, including widespread loanwords, and use of a vigesimal number system.

The territory of the Maya covered a third of Mesoamerica, and the Maya were engaged in a dynamic relationship with neighbouring cultures that included the Olmecs, Mixtecs, Teotihuacan, the Aztecs, and others. During the Early Classic period, the Maya cities of Tikal and Kaminaljuyu were key Maya foci in a network that extended beyond the Maya area into the highlands of central Mexico. At around the same time, there was a strong Maya presence at the Tetitla compound of Teotihuacan. Centuries later, during the 9th century AD, murals at Cacaxtla, another site in the central Mexican highlands, were painted in a Maya style. This may have been either an effort to align itself with the still-powerful Maya area after the collapse of Teotihuacan and ensuing political fragmentation in the Mexican Highlands, or an attempt to express a distant Maya origin of the inhabitants. The Maya city of Chichen Itza and the distant Toltec capital of Tula had an especially close relationship.

Geography

Maya area

The Maya civilization occupied a wide territory that included southeastern Mexico and northern Central America. This area included the entire Yucatán Peninsula and all of the territory now incorporated into the modern countries of Guatemala and Belize, as well as the western portions of Honduras and El Salvador. Most of the peninsula is formed by a vast plain with few hills or mountains and a generally low coastline.

The Petén region consists of densely forested low-lying limestone plain; a chain of fourteen lakes runs across the central drainage basin of Petén. To the south the plain gradually rises towards the Guatemalan Highlands. Dense forest covers northern Petén and Belize, most of Quintana Roo, southern Campeche, and a portion of the south of Yucatán state. Farther north, the vegetation turns to lower forest consisting of dense scrub.

The littoral zone of Soconusco lies to the south of the Sierra Madre de Chiapas, and consists of a narrow coastal plain and the foothills of the Sierra Madre. The Maya highlands extend eastwards from Chiapas into Guatemala, reaching their highest in the Sierra de los Cuchumatanes. The major pre-Columbian population centres of the highlands were located in the largest highland valleys, such as the Valley of Guatemala and the Quetzaltenango Valley. In the southern highlands, a belt of volcanic cones runs parallel to the Pacific coast. The highlands extend northwards into Verapaz, and gradually descend to the east.

History

The history of Maya civilization is divided into three principal periods: the Preclassic, Classic, and Postclassic periods. These were preceded by the Archaic Period, during which the first settled villages and early developments in agriculture emerged. Modern scholars regard these periods as arbitrary divisions of Maya chronology, rather than indicative of cultural evolution or decline. Definitions of the start and end dates of period spans can vary by as much as a century, depending on the author.

Preclassic period (c. 2000 BC – 250 AD)

Kaminaljuyu, in the highlands, and El Mirador, in the lowlands, were both important cities in the Late Preclassic.

The Maya developed their first civilization in the Preclassic period. Scholars continue to discuss when this era of Maya civilization began. Maya occupation at Cuello (modern-day Belize) has been carbon dated to around 2600 BC. Settlements were established around 1800 BC in the Soconusco region of the Pacific coast, and the Maya were already cultivating the staple crops of maize, beans, squash, and chili pepper. This period was characterised by sedentary communities and the introduction of pottery and fired clay figurines.

During the Middle Preclassic Period, small villages began to grow to form cities. Nakbe in the Petén department of Guatemala is the earliest well-documented city in the Maya lowlands, where large structures have been dated to around 750 BC. The northern lowlands of Yucatán were widely settled by the Middle Preclassic. By approximately 400 BC, early Maya rulers were raising stelae. A developed script was already being used in Petén by the 3rd century BC. In the Late Preclassic Period, the enormous city of El Mirador grew to cover approximately 16 square kilometres (6.2 sq mi). Although not as large, Tikal was already a significant city by around 350 BC.

In the highlands, Kaminaljuyu emerged as a principal centre in the Late Preclassic. Takalik Abaj and Chocolá were two of the most important cities on the Pacific coastal plain, and Komchen grew to become an important site in northern Yucatán. The Late Preclassic cultural florescence collapsed in the 1st century AD and many of the great Maya cities of the epoch were abandoned; the cause of this collapse is unknown.

Classic period (c. 250–900 AD)

The Classic period is largely defined as the period during which the lowland Maya raised dated monuments using the Long Count calendar. This period marked the peak of large-scale construction and urbanism, the recording of monumental inscriptions, and demonstrated significant intellectual and artistic development, particularly in the southern lowland regions. The Classic period Maya political landscape has been likened to that of Renaissance Italy or Classical Greece, with multiple city-states engaged in a complex network of alliances and enmities. The largest cities had populations numbering 50,000 to 120,000 and were linked to networks of subsidiary sites.

During the Early Classic, cities throughout the Maya region were influenced by the great metropolis of Teotihuacan in the distant Valley of Mexico. In AD 378, Teotihuacan decisively intervened at Tikal and other nearby cities, deposed their rulers, and installed a new Teotihuacan-backed dynasty. This intervention was led by Siyaj Kʼakʼ ("Born of Fire"), who arrived at Tikal in early 378. The king of Tikal, Chak Tok Ichʼaak I, died on the same day, suggesting a violent takeover. A year later, Siyaj Kʼakʼ oversaw the installation of a new king, Yax Nuun Ahiin I. The installation of the new dynasty led to a period of political dominance when Tikal became the most powerful city in the central lowlands.

Tikal's great rival was Calakmul, another powerful city in the Petén Basin. Tikal and Calakmul both developed extensive systems of allies and vassals; lesser cities that entered one of these networks gained prestige from their association with the top-tier city, and maintained peaceful relations with other members of the same network. Tikal and Calakmul engaged in the manoeuvering of their alliance networks against each other. At various points during the Classic period, one or other of these powers would gain a strategic victory over its great rival, resulting in respective periods of florescence and decline.

Calakmul was one of the most important Classic period cities.

In 629, Bʼalaj Chan Kʼawiil, a son of the Tikal king Kʼinich Muwaan Jol II, was sent to found a new city at Dos Pilas, in the Petexbatún region, apparently as an outpost to extend Tikal's power beyond the reach of Calakmul. For the next two decades he fought loyally for his brother and overlord at Tikal. In 648, king Yuknoom Chʼeen II of Calakmul captured Balaj Chan Kʼawiil. Yuknoom Chʼeen II then reinstated Balaj Chan Kʼawiil upon the throne of Dos Pilas as his vassal. He thereafter served as a loyal ally of Calakmul.

In the southeast, Copán was the most important city. Its Classic-period dynasty was founded in 426 by Kʼinich Yax Kʼukʼ Moʼ. The new king had strong ties with central Petén and Teotihuacan. Copán reached the height of its cultural and artistic development during the rule of Uaxaclajuun Ubʼaah Kʼawiil, who ruled from 695 to 738. His reign ended catastrophically when he was captured by his vassal, king Kʼakʼ Tiliw Chan Yopaat of Quiriguá. The captured lord of Copán was taken back to Quiriguá and was decapitated in a public ritual. It is likely that this coup was backed by Calakmul, in order to weaken a powerful ally of Tikal. Palenque and Yaxchilan were the most powerful cities in the Usumacinta region. In the highlands, Kaminaljuyu in the Valley of Guatemala was already a sprawling city by 300. In the north of the Maya area, Coba was the most important capital.

Classic Maya collapse

Chichen Itza was the most important city in the northern Maya region.

During the 9th century AD, the central Maya region suffered major political collapse, marked by the abandonment of cities, the ending of dynasties, and a northward shift in activity. No universally accepted theory explains this collapse, but it likely had a combination of causes, including endemic internecine warfare, overpopulation resulting in severe environmental degradation, and drought. During this period, known as the Terminal Classic, the northern cities of Chichen Itza and Uxmal showed increased activity. Major cities in the northern Yucatán Peninsula continued to be inhabited long after the cities of the southern lowlands ceased to raise monuments.

Classic Maya social organization was based on the ritual authority of the ruler, rather than central control of trade and food distribution. This model of rulership was poorly structured to respond to changes, because the ruler's actions were limited by tradition to such activities as construction, ritual, and warfare. This only served to exacerbate systemic problems. By the 9th and 10th centuries, this resulted in collapse of this system of rulership. In the northern Yucatán, individual rule was replaced by a ruling council formed from elite lineages. In the southern Yucatán and central Petén, kingdoms declined; in western Petén and some other areas, the changes were catastrophic and resulted in the rapid depopulation of cities. Within a couple of generations, large swathes of the central Maya area were all but abandoned. Both the capitals and their secondary centres were generally abandoned within a period of 50 to 100 years. One by one, cities stopped sculpting dated monuments; the last Long Count date was inscribed at Toniná in 909. Stelae were no longer raised, and squatters moved into abandoned royal palaces. Mesoamerican trade routes shifted and bypassed Petén.

Postclassic period (c. 950–1539 AD)

Zaculeu was capital of the Postclassic Mam kingdom in the Guatemalan Highlands.

Although much reduced, a significant Maya presence remained into the Postclassic period after the abandonment of the major Classic period cities; the population was particularly concentrated near permanent water sources. Unlike during previous cycles of contraction in the Maya region, abandoned lands were not quickly resettled in the Postclassic. Activity shifted to the northern lowlands and the Maya Highlands; this may have involved migration from the southern lowlands, because many Postclassic Maya groups had migration myths. Chichen Itza and its Puuc neighbours declined dramatically in the 11th century, and this may represent the final episode of Classic Period collapse. After the decline of Chichen Itza, the Maya region lacked a dominant power until the rise of the city of Mayapan in the 12th century. New cities arose near the Caribbean and Gulf coasts, and new trade networks were formed.

The Postclassic Period was marked by changes from the preceding Classic Period. The once-great city of Kaminaljuyu in the Valley of Guatemala was abandoned after continuous occupation of almost 2,000 years. Across the highlands and neighbouring Pacific coast, long-occupied cities in exposed locations were relocated, apparently due to a proliferation of warfare. Cities came to occupy more-easily defended hilltop locations surrounded by deep ravines, with ditch-and-wall defences sometimes supplementing the protection provided by the natural terrain. One of the most important cities in the Guatemalan Highlands at this time was Qʼumarkaj, the capital of the aggressive Kʼicheʼ kingdom. The government of Maya states, from the Yucatán to the Guatemalan highlands, was often organised as joint rule by a council. However, in practice one member of the council could act as a supreme ruler, while the other members served him as advisors.

Mayapan was an important Postclassic city in the northern Yucatán Peninsula.

Mayapan was abandoned around 1448, after a period of political, social and environmental turbulence that in many ways echoed the Classic period collapse in the southern Maya region. The abandonment of the city was followed by a period of prolonged warfare, disease and natural disasters in the Yucatán Peninsula, which ended only shortly before Spanish contact in 1511. Even without a dominant regional capital, the early Spanish explorers reported wealthy coastal cities and thriving marketplaces. During the Late Postclassic, the Yucatán Peninsula was divided into a number of independent provinces that shared a common culture but varied in internal sociopolitical organization. On the eve of the Spanish conquest, the highlands of Guatemala were dominated by several powerful Maya states. The Kʼicheʼ had carved out a small empire covering a large part of the western Guatemalan Highlands and the neighbouring Pacific coastal plain. However, in the decades before the Spanish invasion the Kaqchikel kingdom had been steadily eroding the kingdom of the Kʼicheʼ.

Contact period and Spanish conquest (1511–1697 AD)

In 1511, a Spanish caravel was wrecked in the Caribbean, and about a dozen survivors made landfall on the coast of Yucatán. They were seized by a Maya lord, and most were sacrificed, although two managed to escape. From 1517 to 1519, three separate Spanish expeditions explored the Yucatán coast, and engaged in a number of battles with the Maya inhabitants. After the Aztec capital Tenochtitlan fell to the Spanish in 1521, Hernán Cortés despatched Pedro de Alvarado to Guatemala with 180 cavalry, 300 infantry, 4 cannons, and thousands of allied warriors from central Mexico; they arrived in Soconusco in 1523. The Kʼicheʼ capital, Qʼumarkaj, fell to Alvarado in 1524. Shortly afterwards, the Spanish were invited as allies into Iximche, the capital city of the Kaqchikel Maya. Good relations did not last, due to excessive Spanish demands for gold as tribute, and the city was abandoned a few months later. This was followed by the fall of Zaculeu, the Mam Maya capital, in 1525. Francisco de Montejo and his son, Francisco de Montejo the Younger, launched a long series of campaigns against the polities of the Yucatán Peninsula in 1527, and finally completed the conquest of the northern portion of the peninsula in 1546. This left only the Maya kingdoms of the Petén Basin independent. In 1697, Martín de Ursúa launched an assault on the Itza capital Nojpetén and the last independent Maya city fell to the Spanish.

Persistence of Maya culture

The Spanish conquest stripped away most of the defining features of Maya civilization. However, many Maya villages remained remote from Spanish colonial authority, and for the most part continued to manage their own affairs. Maya communities and the nuclear family maintained their traditional day-to-day life. The basic Mesoamerican diet of maize and beans continued, although agricultural output was improved by the introduction of steel tools. Traditional crafts such as weaving, ceramics, and basketry continued to be practised. Community markets and trade in local products continued long after the conquest. At times, the colonial administration encouraged the traditional economy in order to extract tribute in the form of ceramics or cotton textiles, although these were usually made to European specifications. Maya beliefs and language proved resistant to change, despite vigorous efforts by Catholic missionaries. The 260-day tzolkʼin ritual calendar continues in use in modern Maya communities in the highlands of Guatemala and Chiapas, and millions of Mayan-language speakers inhabit the territory in which their ancestors developed their civilization.

Investigation of Maya civilization

The agents of the Catholic Church wrote detailed accounts of the Maya, in support of their efforts at Christianization, and absorption of the Maya into the Spanish Empire. This was followed by various Spanish priests and colonial officials who left descriptions of ruins they visited in Yucatán and Central America. In 1839, American traveller and writer John Lloyd Stephens set out to visit a number of Maya sites with English architect and draftsman Frederick Catherwood. Their illustrated accounts of the ruins sparked strong popular interest, and brought the Maya to the attention of the world. The later 19th century saw the recording and recovery of ethnohistoric accounts of the Maya, and the first steps in deciphering Maya hieroglyphs.

The final two decades of the 19th century saw the birth of modern scientific archaeology in the Maya region, with the meticulous work of Alfred Maudslay and Teoberto Maler. By the early 20th century, the Peabody Museum was sponsoring excavations at Copán and in the Yucatán Peninsula. In the first two decades of the 20th century, advances were made in deciphering the Maya calendar, and identifying deities, dates, and religious concepts. Since the 1930s, archaeological exploration increased dramatically, with large-scale excavations across the Maya region.

In the 1960s, the distinguished Mayanist J. Eric S. Thompson promoted the ideas that Maya cities were essentially vacant ceremonial centres serving a dispersed population in the forest, and that the Maya civilization was governed by peaceful astronomer-priests. These ideas began to collapse with major advances in the decipherment of the script in the late 20th century, pioneered by Heinrich Berlin, Tatiana Proskouriakoff, and Yuri Knorozov. With breakthroughs in understanding of Maya script since the 1950s, the texts revealed the warlike activities of the Classic Maya kings, and the view of the Maya as peaceful could no longer be supported.

Politics

Unlike the Aztecs and the Inca, the Maya political system never integrated the entire Maya cultural area into a single state or empire. Rather, throughout its history, the Maya area contained a varying mix of political complexity that included both states and chiefdoms. These polities fluctuated greatly in their relationships with each other and were engaged in a complex web of rivalries, periods of dominance or submission, vassalage, and alliances. At times, different polities achieved regional dominance, such as Calakmul, Caracol, Mayapan, and Tikal. The first reliably evidenced polities formed in the Maya lowlands in the 9th century BC.

During the Late Preclassic, the Maya political system coalesced into a theopolitical form, where elite ideology justified the ruler's authority, and was reinforced by public display, ritual, and religion. The divine king was the centre of political power, exercising ultimate control over the administrative, economic, judicial, and military functions of the polity. The divine authority invested within the ruler was such that the king was able to mobilize both the aristocracy and commoners in executing huge infrastructure projects, apparently with no police force or standing army. Some polities engaged in a strategy of increasing administration, and filling administrative posts with loyal supporters rather than blood relatives. Within a polity, mid-ranking population centres would have played a key role in managing resources and internal conflict.

The Maya political landscape was highly complex and Maya elites engaged in political intrigue to gain economic and social advantage over neighbours. In the Late Classic, some cities established a long period of dominance over other large cities, such as the dominance of Caracol over Naranjo for half a century. In other cases, loose alliance networks were formed around a dominant city. Border settlements, usually located about halfway between neighbouring capitals, often switched allegiance over the course of their history, and at times acted independently. Dominant capitals exacted tribute in the form of luxury items from subjugated population centres. Political power was reinforced by military power, and the capture and humiliation of enemy warriors played an important part in elite culture. An overriding sense of pride and honour among the warrior aristocracy could lead to extended feuds and vendettas, which caused political instability and the fragmentation of polities.

Society

From the Early Preclassic, Maya society was sharply divided between the elite and commoners. As population increased over time, various sectors of society became increasingly specialised, and political organization became increasingly complex. By the Late Classic, when populations had grown enormously and hundreds of cities were connected in a complex web of political hierarchies, the wealthy segment of society multiplied. A middle class may have developed that included artisans, low ranking priests and officials, merchants, and soldiers. Commoners included farmers, servants, labourers, and slaves. According to indigenous histories, land was held communally by noble houses or clans. Such clans held that the land was the property of the clan ancestors, and such ties between the land and the ancestors were reinforced by the burial of the dead within residential compounds.

King and court

Classic Maya rule was centred in a royal culture that was displayed in all areas of Classic Maya art. The king was the supreme ruler and held a semi-divine status that made him the mediator between the mortal realm and that of the gods. From very early times, kings were specifically identified with the young maize god, whose gift of maize was the basis of Mesoamerican civilization. Maya royal succession was patrilineal, and royal power only passed to queens when doing otherwise would result in the extinction of the dynasty. Typically, power was passed to the eldest son. A young prince was called a chʼok ("youth"), although this word later came to refer to nobility in general. The royal heir was called bʼaah chʼok ("head youth"). Various points in the young prince's childhood were marked by ritual; the most important was a bloodletting ceremony at age five or six years. Although being of the royal bloodline was of utmost importance, the heir also had to be a successful war leader, as demonstrated by taking of captives. The enthronement of a new king was a highly elaborate ceremony, involving a series of separate acts that included enthronement upon a jaguar-skin cushion, human sacrifice, and receiving the symbols of royal power, such as a headband bearing a jade representation of the so-called "jester god", an elaborate headdress adorned with quetzal feathers, and a sceptre representing the god Kʼawiil.

Maya political administration, based around the royal court, was not bureaucratic in nature. Government was hierarchical, and official posts were sponsored by higher-ranking members of the aristocracy; officials tended to be promoted to higher levels of office during the course of their lives. Officials are referred to as being "owned" by their sponsor, and this relationship continued even after the death of the sponsor. The Maya royal court was a vibrant and dynamic political institution. There was no universal structure for the Maya royal court, instead each polity formed a royal court that was suited to its own individual context. A number of royal and noble titles have been identified by epigraphers translating Classic Maya inscriptions. Ajaw is usually translated as "lord" or "king". In the Early Classic, an ajaw was the ruler of a city. Later, with increasing social complexity, the ajaw was a member of the ruling class and a major city could have more than one, each ruling over different districts. Paramount rulers distinguished themselves from the extended nobility by prefixing the word kʼuhul to their ajaw title. A kʼuhul ajaw was "divine lord", originally confined to the kings of the most prestigious and ancient royal lines. Kalomte was a royal title, whose exact meaning is not yet deciphered, but it was held only by the most powerful kings of the strongest dynasties. It indicated an overlord, or high king, and the title was only in use during the Classic period. By the Late Classic, the absolute power of the kʼuhul ajaw had weakened, and the political system had diversified to include a wider aristocracy, that by this time may well have expanded disproportionately.

A sajal was ranked below the ajaw, and indicated a subservient lord. A sajal would be lord of a second- or third-tier site, answering to an ajaw, who may himself have been subservient to a kalomte. A sajal would often be a war captain or regional governor, and inscriptions often link the sajal title to warfare; they are often mentioned as the holders of war captives. Sajal meant "feared one". The titles of ah tzʼihb and ah chʼul hun are both related to scribes. The ah tzʼihb was a royal scribe, usually a member of the royal family; the ah chʼul hun was the Keeper of the Holy Books, a title that is closely associated with the ajaw title, indicating that an ajaw always held the ah chʼul hun title simultaneously. Other courtly titles, the functions of which are not well understood, were yajaw kʼahk' ("Lord of Fire"), tiʼhuun and ti'sakhuun. These last two may be variations on the same title, and Mark Zender has suggested that the holder of this title may have been the spokesman for the ruler. Courtly titles are overwhelmingly male-oriented, and in those relatively rare occasions where they are applied to a woman, they appear to be used as honorifics for female royalty. Titled elites were often associated with particular structures in the hieroglyphic inscriptions of Classic period cities, indicating that such office holders either owned that structure, or that the structure was an important focus for their activities. A lakam, or standard-bearer, was possibly the only non-elite post-holder in the royal court. The lakam was only found in larger sites, and they appear to have been responsible for the taxation of local districts.

Different factions may have existed in the royal court. The kʼuhul ahaw and his household would have formed the central power-base, but other important groups were the priesthood, the warrior aristocracy, and other aristocratic courtiers. Where ruling councils existed, as at Chichen Itza and Copán, these may have formed an additional faction. Rivalry between different factions would have led to dynamic political institutions as compromises and disagreements were played out. In such a setting, public performance was vital. Such performances included ritual dances, presentation of war captives, offerings of tribute, human sacrifice, and religious ritual.

Commoners

Commoners are estimated to have comprised over 90% of the population, but relatively little is known about them. Their houses were generally constructed from perishable materials, and their remains have left little trace in the archaeological record. Some commoner dwellings were raised on low platforms, and these can be identified, but an unknown quantity of commoner houses were not. Such low-status dwellings can only be detected by extensive remote-sensing surveys of apparently empty terrain. The range of commoners was broad; it consisted of everyone not of noble birth, and therefore included everyone from the poorest farmers to wealthy craftsmen and commoners appointed to bureaucratic positions. Commoners engaged in essential production activities, including that of products destined for use by the elite, such as cotton and cacao, as well as subsistence crops for their own use, and utilitarian items such as ceramics and stone tools. Commoners took part in warfare, and could advance socially by proving themselves as outstanding warriors. Commoners paid taxes to the elite in the form of staple goods such as maize, flour and game. It is likely that hard-working commoners who displayed exceptional skills and initiative could become influential members of Maya society.

Warfare

Warfare was prevalent in the Maya world. Military campaigns were launched for a variety of reasons, including the control of trade routes and tribute, raids to take captives, scaling up to the complete destruction of an enemy state. Little is known about Maya military organization, logistics, or training. Warfare is depicted in Maya art from the Classic period, and wars and victories are mentioned in hieroglyphic inscriptions. Unfortunately, the inscriptions do not provide information upon the causes of war, or the form it took. In the 8th–9th centuries, intensive warfare resulted in the collapse of the kingdoms of the Petexbatún region of western Petén. The rapid abandonment of Aguateca by its inhabitants has provided a rare opportunity to examine the remains of Maya weaponry in situ. Aguateca was stormed by unknown enemies around 810 AD, who overcame its formidable defences and burned the royal palace. The elite inhabitants of the city either fled or were captured, and never returned to collect their abandoned property. The inhabitants of the periphery abandoned the site soon after. This is an example of intensive warfare carried out by an enemy in order to eliminate a Maya state, rather than subjugate it. Research at Aguateca indicated that Classic period warriors were primarily members of the elite.

From as early as the Preclassic period, the ruler of a Maya polity was expected to be a distinguished war leader, and was depicted with trophy heads hanging from his belt. In the Classic period, such trophy heads no longer appeared on the king's belt, but Classic period kings are frequently depicted standing over humiliated war captives. Right up to the end of the Postclassic period, Maya kings led as war captains. Maya inscriptions from the Classic show that a defeated king could be captured, tortured, and sacrificed. The Spanish recorded that Maya leaders kept track of troop movements in painted books.

The outcome of a successful military campaign could vary in its impact on the defeated polity. In some cases, entire cities were sacked, and never resettled, as at Aguateca. In other instances, the victors would seize the defeated rulers, their families, and patron gods. The captured nobles and their families could be imprisoned, or sacrificed. At the least severe end of the scale, the defeated polity would be obliged to pay tribute to the victor.

Warriors

During the Contact period, it is known that certain military positions were held by members of the aristocracy, and were passed on by patrilineal succession. It is likely that the specialised knowledge inherent in the particular military role was taught to the successor, including strategy, ritual, and war dances. Maya armies of the Contact period were highly disciplined, and warriors participated in regular training exercises and drills; every able-bodied adult male was available for military service. Maya states did not maintain standing armies; warriors were mustered by local officials who reported back to appointed warleaders. There were also units of full-time mercenaries who followed permanent leaders. Most warriors were not full-time, however, and were primarily farmers; the needs of their crops usually came before warfare. Maya warfare was not so much aimed at destruction of the enemy as the seizure of captives and plunder.

There is some evidence from the Classic period that women provided supporting roles in war, but they did not act as military officers with the exception of those rare ruling queens. By the Postclassic, the native chronicles suggest that women occasionally fought in battle.

Weapons

The atlatl (spear-thrower) was introduced to the Maya region by Teotihuacan in the Early Classic. This was a 0.5-metre-long (1.6 ft) stick with a notched end to hold a dart or javelin. The stick was used to launch the missile with more force and accuracy than could be accomplished by simply hurling it with the arm alone. Evidence in the form of stone blade points recovered from Aguateca indicate that darts and spears were the primary weapons of the Classic Maya warrior. Commoners used blowguns in war, which also served as their hunting weapon. The bow and arrow is another weapon that was used by the ancient Maya for both war and hunting. Although present in the Maya region during the Classic period, its use as a weapon of war was not favoured; it did not become a common weapon until the Postclassic. The Contact period Maya also used two-handed swords crafted from strong wood with the blade fashioned from inset obsidian, similar to the Aztec macuahuitl. Maya warriors wore body armour in the form of quilted cotton that had been soaked in salt water to toughen it; the resulting armour compared favourably to the steel armour worn by the Spanish when they conquered the region. Warriors bore wooden or animal hide shields decorated with feathers and animal skins.

Trade

Trade was a key component of Maya society, and in the development of the Maya civilization. The cities that grew to become the most important usually controlled access to vital trade goods, or portage routes. Cities such as Kaminaljuyu and Qʼumarkaj in the Guatemalan Highlands, and Chalchuapa in El Salvador, variously controlled access to the sources of obsidian at different points in Maya history. The Maya were major producers of cotton, which was used to make the textiles to be traded throughout Mesoamerica. The most important cities in the northern Yucatán Peninsula controlled access to the sources of salt. In the Postclassic, the Maya engaged in a flourishing slave trade with wider Mesoamerica.

The Maya engaged in long-distance trade across the Maya region, and across greater Mesoamerica and beyond. As an illustration, an Early Classic Maya merchant quarter has been identified at the distant metropolis of Teotihuacan, in central Mexico. Within Mesoamerica beyond the Maya area, trade routes particularly focused on central Mexico and the Gulf coast. In the Early Classic, Chichen Itza was at the hub of an extensive trade network that imported gold discs from Colombia and Panama, and turquoise from Los Cerrillos, New Mexico. Long-distance trade of both luxury and utilitarian goods was probably controlled by the royal family. Prestige goods obtained by trade were used both for consumption by the city's ruler, and as luxury gifts to consolidate the loyalty of vassals and allies.

Trade routes not only supplied physical goods, they facilitated the movement of people and ideas throughout Mesoamerica. Shifts in trade routes occurred with the rise and fall of important cities in the Maya region, and have been identified in every major reorganization of the Maya civilization, such as the rise of Preclassic Maya civilization, the transition to the Classic, and the Terminal Classic collapse. Even the Spanish Conquest did not immediately terminate all Maya trading activity; for example, the Contact period Manche Chʼol traded the prestige crops of cacao, annatto and vanilla into colonial Verapaz.

Merchants

Little is known of Maya merchants, although they are depicted on Maya ceramics in elaborate noble dress. From this, it is known that at least some traders were members of the elite. During the Contact period, it is known that Maya nobility took part in long-distance trading expeditions. The majority of traders were middle class, but were largely engaged in local and regional trade rather than the prestigious long-distance trading that was the preserve of the elite. The travelling of merchants into dangerous foreign territory was likened to a passage through the underworld; the patron deities of merchants were two underworld gods carrying backpacks. When merchants travelled, they painted themselves black, like their patron gods, and went heavily armed.

The Maya had no pack animals, so all trade goods were carried on the backs of porters when going overland; if the trade route followed a river or the coast, then goods were transported in canoes. A substantial Maya trading canoe was encountered off Honduras on Christopher Columbus's fourth voyage. It was made from a large hollowed-out tree trunk and had a palm-covered canopy. The canoe was 2.5 metres (8.2 ft) broad and was powered by 25 rowers. Trade goods carried included cacao, obsidian, ceramics, textiles, food and drink for the crew, and copper bells and axes. Cacao was used as currency (although not exclusively), and its value was such that counterfeiting occurred by removing the flesh from the pod, and stuffing it with dirt or avocado rind.

Marketplaces

Marketplaces are difficult to identify archaeologically. However, the Spanish reported a thriving market economy when they arrived in the region. At some Classic period cities, archaeologists have tentatively identified formal arcade-style masonry architecture and parallel alignments of scattered stones as the permanent foundations of market stalls. A 2007 study analysed soils from a modern Guatemalan market and compared the results with those obtained from analysis at a proposed ancient market at Chunchucmil. Unusually high levels of zinc and phosphorus at both sites indicated similar food production and vegetable sales activity. The calculated density of market stalls at Chunchucmil strongly suggests that a thriving market economy already existed in the Early Classic. Archaeologists have tentatively identified marketplaces at an increasing number of Maya cities by means of a combination of archaeology and soil analysis. When the Spanish arrived, Postclassic cities in the highlands had markets in permanent plazas, with officials on hand to settle disputes, enforce rules, and collect taxes.

Art

Maya art is essentially the art of the royal court. It is almost exclusively concerned with the Maya elite and their world. Maya art was crafted from both perishable and non-perishable materials, and served to link the Maya to their ancestors. Although surviving Maya art represents only a small proportion of the art that the Maya created, it represents a wider variety of subjects than any other art tradition in the Americas. Maya art has many regional styles, and is unique in the ancient Americas in bearing narrative text. The finest surviving Maya art dates to the Late Classic period.

The Maya exhibited a preference for the colour green or blue-green, and used the same word for the colours blue and green. Correspondingly, they placed high value on apple-green jade, and other greenstones, associating them with the sun-god Kʼinich Ajau. They sculpted artefacts that included fine tesserae and beads, to carved heads weighing 4.42 kilograms (9.7 lb). The Maya nobility practised dental modification, and some lords wore encrusted jade in their teeth. Mosaic funerary masks could also be fashioned from jade, such as that of Kʼinich Janaabʼ Pakal, king of Palenque.

Maya stone sculpture emerged into the archaeological record as a fully developed tradition, suggesting that it may have evolved from a tradition of sculpting wood. Because of the biodegradability of wood, the corpus of Maya woodwork has almost entirely disappeared. The few wooden artefacts that have survived include three-dimensional sculptures, and hieroglyphic panels. Stone Maya stelae are widespread in city sites, often paired with low, circular stones referred to as altars in the literature. Stone sculpture also took other forms, such as the limestone relief panels at Palenque and Piedras Negras. At Yaxchilan, Dos Pilas, Copán, and other sites, stone stairways were decorated with sculpture. The hieroglyphic stairway at Copán comprises the longest surviving Maya hieroglyphic text, and consists of 2,200 individual glyphs.

The largest Maya sculptures consisted of architectural façades crafted from stucco. The rough form was laid out on a plain plaster base coating on the wall, and the three-dimensional form was built up using small stones. Finally, this was coated with stucco and moulded into the finished form; human body forms were first modelled in stucco, with their costumes added afterwards. The final stucco sculpture was then brightly painted. Giant stucco masks were used to adorn temple façades by the Late Preclassic, and such decoration continued into the Classic period.

The Maya had a long tradition of mural painting; rich polychrome murals have been excavated at San Bartolo, dating to between 300 and 200 BC. Walls were coated with plaster, and polychrome designs were painted onto the smooth finish. The majority of such murals have not survived, but Early Classic tombs painted in cream, red, and black have been excavated at Caracol, Río Azul, and Tikal. Among the best preserved murals are a full-size series of Late Classic paintings at Bonampak.

Flint, chert, and obsidian all served utilitarian purposes in Maya culture, but many pieces were finely crafted into forms that were never intended to be used as tools. Eccentric flints are among the finest lithic artefacts produced by the ancient Maya. They were technically very challenging to produce, requiring considerable skill on the part of the artisan. Large obsidian eccentrics can measure over 30 centimetres (12 in) in length. Their actual form varies considerably but they generally depict human, animal and geometric forms associated with Maya religion. Eccentric flints show a great variety of forms, such as crescents, crosses, snakes, and scorpions. The largest and most elaborate examples display multiple human heads, with minor heads sometimes branching off from larger one.

Maya textiles are very poorly represented in the archaeological record, although by comparison with other pre-Columbian cultures, such as the Aztecs and the Andean region, it is likely that they were high-value items. A few scraps of textile have been recovered by archaeologists, but the best evidence for textile art is where they are represented in other media, such as painted murals or ceramics. Such secondary representations show the elite of the Maya court adorned with sumptuous cloths, generally these would have been cotton, but jaguar pelts and deer hides are also shown.

Ceramics are the most commonly surviving type of Maya art. The Maya had no knowledge of the potter's wheel, and Maya vessels were built up by coiling rolled strips of clay into the desired form. Maya pottery was not glazed, although it often had a fine finish produced by burnishing. Maya ceramics were painted with clay slips blended with minerals and coloured clays. Ancient Maya firing techniques have yet to be replicated. A quantity of extremely fine ceramic figurines have been excavated from Late Classic tombs on Jaina Island, in northern Yucatán. They stand from 10 to 25 centimetres (3.9 to 9.8 in) high and were hand modelled, with exquisite detail. The Ik-style polychrome ceramic corpus, including finely painted plates and cylindrical vessels, originated in Late Classic Motul de San José. It includes a set of features such as hieroglyphs painted in a pink or pale red colour and scenes with dancers wearing masks. One of the most distinctive features is the realistic representation of subjects as they appeared in life. The subject matter of the vessels includes courtly life from the Petén region in the 8th century AD, such as diplomatic meetings, feasting, bloodletting, scenes of warriors and the sacrifice of prisoners of war.

Bone, both human and animal, was also sculpted; human bones may have been trophies, or relics of ancestors. The Maya valued Spondylus shells, and worked them to remove the white exterior and spines, to reveal the fine orange interior. Around the 10th century AD, metallurgy arrived in Mesoamerica from South America, and the Maya began to make small objects in gold, silver and copper. The Maya generally hammered sheet metal into objects such as beads, bells, and discs. In the last centuries before the Spanish Conquest, the Maya began to use the lost-wax method to cast small metal pieces.

One poorly studied area of Maya folk art is graffiti. Additional graffiti, not part of the planned decoration, was incised into the stucco of interior walls, floors, and benches, in a wide variety of buildings, including temples, residences, and storerooms. Graffiti has been recorded at 51 Maya sites, particularly clustered in the Petén Basin and southern Campeche, and the Chenes region of northwestern Yucatán. At Tikal, where a great quantity of graffiti has been recorded, the subject matter includes drawings of temples, people, deities, animals, banners, litters, and thrones. Graffiti was often inscribed haphazardly, with drawings overlapping each other, and display a mix of crude, untrained art, and examples by artists who were familiar with Classic-period artistic conventions.

Architecture

The Maya produced a vast array of structures, and have left an extensive architectural legacy. Maya architecture also incorporates various art forms and hieroglyphic texts. Masonry architecture built by the Maya evidences craft specialization in Maya society, centralised organization and the political means to mobilize a large workforce. It is estimated that a large elite residence at Copán required an estimated 10,686 man-days to build, which compares to 67-man-days for a commoner's hut. It is further estimated that 65% of the labour required to build the noble residence was used in the quarrying, transporting, and finishing of the stone used in construction, and 24% of the labour was required for the manufacture and application of limestone-based plaster. Altogether, it is estimated that two to three months were required for the construction of the residence for this single noble at Copán, using between 80 and 130 full-time labourers. A Classic-period city like Tikal was spread over 20 square kilometres (7.7 sq mi), with an urban core covering 6 square kilometres (2.3 sq mi). The labour required to build such a city was immense, running into many millions of man-days. The most massive structures ever erected by the Maya were built during the Preclassic period. Craft specialization would have required dedicated stonemasons and plasterers by the Late Preclassic, and would have required planners and architects.

Urban design

Reconstruction of the urban core of Tikal in the 8th century AD

Maya cities were not formally planned, and were subject to irregular expansion, with the haphazard addition of palaces, temples and other buildings. Most Maya cities tended to grow outwards from the core, and upwards as new structures were superimposed upon preceding architecture. Maya cities usually had a ceremonial and administrative centre surrounded by a vast irregular sprawl of residential complexes. The centres of all Maya cities featured sacred precincts, sometimes separated from nearby residential areas by walls. These precincts contained pyramid temples and other monumental architecture dedicated to elite activities, such as basal platforms that supported administrative or elite residential complexes. Sculpted monuments were raised to record the deeds of the ruling dynasty. City centres also featured plazas, sacred ballcourts and buildings used for marketplaces and schools. Frequently causeways linked the centre to outlying areas of the city. Some of these classes of architecture formed lesser groups in the outlying areas of the city, which served as sacred centres for non-royal lineages. The areas adjacent to these sacred compounds included residential complexes housing wealthy lineages. The largest and richest of these elite compounds sometimes possessed sculpture and art of craftsmanship equal to that of royal art.

The ceremonial centre of the Maya city was where the ruling elite lived, and where the administrative functions of the city were performed, together with religious ceremonies. It was also where the inhabitants of the city gathered for public activities. Elite residential complexes occupied the best land around the city centre, while commoners had their residences dispersed further away from the ceremonial centre. Residential units were built on top of stone platforms to raise them above the level of the rain season floodwaters.

Building materials and methods

Fired bricks with animal designs from Comalcalco. Made from brick since there was a lack of readily available stone, it is unique among major Maya sites.

The Maya built their cities with Neolithic technology; they built their structures from both perishable materials and from stone. The exact type of stone used in masonry construction varied according to locally available resources, and this also affected the building style. Across a broad swathe of the Maya area, limestone was immediately available. The local limestone is relatively soft when freshly cut, but hardens with exposure. There was great variety in the quality of limestone, with good-quality stone available in the Usumacinta region; in the northern Yucatán, the limestone used in construction was of relatively poor quality. Volcanic tuff was used at Copán, and nearby Quiriguá employed sandstone. In Comalcalco, where suitable stone was not available locally, fired bricks were employed. Limestone was burned at high temperatures in order to manufacture cement, plaster, and stucco. Lime-based cement was used to seal stonework in place, and stone blocks were fashioned using rope-and-water abrasion, and with obsidian tools. The Maya did not employ a functional wheel, so all loads were transported on litters, barges, or rolled on logs. Heavy loads were lifted with rope, but probably without employing pulleys.

Wood was used for beams, and for lintels, even in masonry structures. Throughout Maya history, common huts and some temples continued to be built from wooden poles and thatch. Adobe was also applied; this consisted of mud strengthened with straw and was applied as a coating over the woven-stick walls of huts. Like wood and thatch, adobe was used throughout Maya history, even after the development of masonry structures. In the southern Maya area, adobe was employed in monumental architecture when no suitable stone was locally available.

Principal construction types

The great cities of the Maya civilization were composed of pyramid temples, palaces, ballcourts, sacbeob (causeways), patios and plazas. Some cities also possessed extensive hydraulic systems or defensive walls. The exteriors of most buildings were painted, either in one or multiple colours, or with imagery. Many buildings were adorned with sculpture or painted stucco reliefs.

Palaces and acropoleis

Terminal Classic palace complex at Sayil, in northern Yucatán

These complexes were usually located in the site core, beside a principal plaza. Maya palaces consisted of a platform supporting a multiroom range structure. The term acropolis, in a Maya context, refers to a complex of structures built upon platforms of varying height. Palaces and acropoleis were essentially elite residential compounds. They generally extended horizontally as opposed to the towering Maya pyramids, and often had restricted access. Some structures in Maya acropoleis supported roof combs. Rooms often had stone benches, used for sleeping, and holes indicate where curtains once hung. Large palaces, such as at Palenque, could be fitted with a water supply, and sweat baths were often found within the complex, or nearby. During the Early Classic, rulers were sometimes buried underneath the acropolis complex. Some rooms in palaces were true throne rooms; in the royal palace of Palenque there were a number of throne rooms that were used for important events, including the inauguration of new kings.

Palaces are usually arranged around one or more courtyards, with their façades facing inwards; some examples are adorned with sculpture. Some palaces possess associated hieroglyphic descriptions that identify them as the royal residences of named rulers. There is abundant evidence that palaces were far more than simple elite residences, and that a range of courtly activities took place in them, including audiences, formal receptions, and important rituals.

Pyramids and temples

Temple I, at Tikal, was a funerary temple in honour of king Jasaw Chan Kʼawiil I.

Temples were sometimes referred to in hieroglyphic texts as kʼuh nah, meaning "god's house". Temples were raised on platforms, most often upon a pyramid. The earliest temples were probably thatched huts built upon low platforms. By the Late Preclassic period, their walls were of stone, and the development of the corbel arch allowed stone roofs to replace thatch. By the Classic period, temple roofs were being topped with roof combs that extended the height of the temple and served as a foundation for monumental art. The temple shrines contained between one and three rooms, and were dedicated to important deities. Such a deity might be one of the patron gods of the city, or a deified ancestor. In general, freestanding pyramids were shrines honouring powerful ancestors.

E-Groups and observatories

The Maya were keen observers of the sun, stars, and planets. E-Groups were a particular arrangement of temples that were relatively common in the Maya region; they take their names from Group E at Uaxactun. They consisted of three small structures facing a fourth structure, and were used to mark the solstices and equinoxes. The earliest examples date to the Preclassic period. The Lost World complex at Tikal started out as an E-Group built towards the end of the Middle Preclassic. Due to its nature, the basic layout of an E-Group was constant. A structure was built on the west side of a plaza; it was usually a radial pyramid with stairways facing the cardinal directions. It faced east across the plaza to three small temples on the far side. From the west pyramid, the sun was seen to rise over these temples on the solstices and equinoxes. E-Groups were raised across the central and southern Maya area for over a millennium; not all were properly aligned as observatories, and their function may have been symbolic.

As well as E-Groups, the Maya built other structures dedicated to observing the movements of celestial bodies. Many Maya buildings were aligned with astronomical bodies, including the planet Venus, and various constellations. The Caracol structure at Chichen Itza was a circular multi-level edifice, with a conical superstructure. It has slit windows that marked the movements of Venus. At Copán, a pair of stelae were raised to mark the position of the setting sun at the equinoxes.

Triadic pyramids

Triadic pyramids first appeared in the Preclassic. They consisted of a dominant structure flanked by two smaller inward-facing buildings, all mounted upon a single basal platform. The largest known triadic pyramid was built at El Mirador in the Petén Basin; it covers an area six times as large as that covered by Temple IV, the largest pyramid at Tikal. The three superstructures all have stairways leading up from the central plaza on top of the basal platform. No securely established forerunners of Triadic Groups are known, but they may have developed from the eastern range building of E-Group complexes. The triadic form was the predominant architectural form in the Petén region during the Late Preclassic. Examples of triadic pyramids are known from as many as 88 archaeological sites. At Nakbe, there are at least a dozen examples of triadic complexes and the four largest structures in the city are triadic in nature. At El Mirador there are probably as many as 36 triadic structures. Examples of the triadic form are even known from Dzibilchaltun in the far north of the Yucatán Peninsula, and Qʼumarkaj in the Highlands of Guatemala. The triadic pyramid remained a popular architectural form for centuries after the first examples were built; it continued in use into the Classic Period, with later examples being found at Uaxactun, Caracol, Seibal, Nakum, Tikal and Palenque. The Qʼumarkaj example is the only one that has been dated to the Postclassic Period. The triple-temple form of the triadic pyramid appears to be related to Maya mythology.

Ballcourts

The ballcourt is a distinctive pan-Mesoamerican form of architecture. Although the majority of Maya ballcourts date to the Classic period, the earliest examples appeared around 1000 BC in northwestern Yucatán, during the Middle Preclassic. By the time of Spanish contact, ballcourts were only in use in the Guatemalan Highlands, at cities such as Qʼumarkaj and Iximche. Throughout Maya history, ballcourts maintained a characteristic form consisting of an ɪ shape, with a central playing area terminating in two transverse end zones. The central playing area usually measures between 20 and 30 metres (66 and 98 ft) long, and is flanked by two lateral structures that stood up to 3 or 4 metres (9.8 or 13.1 ft) high. The lateral platforms often supported structures that may have held privileged spectators. The Great Ballcourt at Chichen Itza is the largest in Mesoamerica, measuring 83 metres (272 ft) long by 30 metres (98 ft) wide, with walls standing 8.2 metres (27 ft) high.

Regional architectural styles

Although Maya cities shared many common features, there was considerable variation in architectural style. Such styles were influenced by locally available construction materials, climate, topography, and local preferences. In the Late Classic, these local differences developed into distinctive regional architectural styles.

Central Petén

The central Petén style of architecture is modelled after the great city of Tikal. The style is characterised by tall pyramids supporting a summit shrine adorned with a roof comb, and accessed by a single doorway. Additional features are the use of stela-altar pairings, and the decoration of architectural façades, lintels, and roof combs with relief sculptures of rulers and gods. One of the finest examples of Central Petén style architecture is Tikal Temple I. Examples of sites in the Central Petén style include Altun Ha, Calakmul, Holmul, Ixkun, Nakum, Naranjo, and Yaxhá.

Puuc

The exemplar of Puuc-style architecture is Uxmal. The style developed in the Puuc Hills of northwestern Yucatán; during the Terminal Classic it spread beyond this core region across the northern Yucatán Peninsula. Puuc sites replaced rubble cores with lime cement, resulting in stronger walls, and also strengthened their corbel arches; this allowed Puuc-style cities to build freestanding entrance archways. The upper façades of buildings were decorated with precut stones mosaic-fashion, erected as facing over the core, forming elaborate compositions of long-nosed deities such as the rain god Chaac and the Principal Bird Deity. The motifs also included geometric patterns, lattices and spools, possibly influenced by styles from highland Oaxaca, outside the Maya area. In contrast, the lower façades were left undecorated. Roof combs were relatively uncommon at Puuc sites.

Chenes

The Chenes style is very similar to the Puuc style, but predates the use of the mosaic façades of the Puuc region. It featured fully adorned façades on both the upper and lower sections of structures. Some doorways were surrounded by mosaic masks of monsters representing mountain or sky deities, identifying the doorways as entrances to the supernatural realm. Some buildings contained interior stairways that accessed different levels. The Chenes style is most commonly encountered in the southern portion of the Yucatán Peninsula, although individual buildings in the style can be found elsewhere in the peninsula. Examples of Chenes sites include Dzibilnocac, Hochob, Santa Rosa Xtampak, and Tabasqueño.

Río Bec

The Río Bec style forms a sub-region of the Chenes style, and also features elements of the Central Petén style, such as prominent roof combs. Its palaces are distinctive for their false-tower decorations, lacking interior rooms, with steep, almost vertical, stairways and false doors. These towers were adorned with deity masks, and were built to impress the viewer, rather than serve any practical function. Such false towers are only found in the Río Bec region. Río Bec sites include Chicanná, Hormiguero, and Xpuhil.

Usumacinta

The Usumacinta style developed in the hilly terrain of the Usumacinta drainage. Cities took advantage of the hillsides to support their major architecture, as at Palenque and Yaxchilan. Sites modified corbel vaulting to allow thinner walls and multiple access doors to temples. As in Petén, roof combs adorned principal structures. Palaces had multiple entrances that used post-and-lintel entrances rather than corbel vaulting. Many sites erected stelae, but Palenque instead developed finely sculpted panelling to decorate its buildings.

Language

Map of Mayan language migration routes

Before 2000 BC, the Maya spoke a single language, dubbed proto-Mayan by linguists. Linguistic analysis of reconstructed Proto-Mayan vocabulary suggests that the original Proto-Mayan homeland was in the western or northern Guatemalan Highlands, although the evidence is not conclusive. Proto-Mayan diverged during the Preclassic period to form the major Mayan language groups that make up the family, including Huastecan, Greater Kʼicheʼan, Greater Qʼanjobalan, Mamean, Tzʼeltalan-Chʼolan, and Yucatecan. These groups diverged further during the pre-Columbian era to form over 30 languages that have survived into modern times. The language of almost all Classic Maya texts over the entire Maya area has been identified as Chʼolan; Late Preclassic text from Kaminaljuyu, in the highlands, also appears to be in, or related to, Chʼolan. The use of Chʼolan as the language of Maya text does not necessarily indicate that it was the language commonly used by the local populace – it may have been equivalent to Medieval Latin as a ritual or prestige language. Classic Chʼolan may have been the prestige language of the Classic Maya elite, used in inter-polity communication such as diplomacy and trade. By the Postclassic period, Yucatec was also being written in Maya codices alongside Chʼolan.

Writing and literacy

The Maya writing system is one of the outstanding achievements of the pre-Columbian inhabitants of the Americas. It was the most sophisticated and highly developed writing system of more than a dozen systems that developed in Mesoamerica. The earliest inscriptions in an identifiably Maya script date back to 300–200 BC, in the Petén Basin. However, this is preceded by several other Mesoamerican writing systems, such as the Epi-Olmec and Zapotec scripts. Early Maya script had appeared on the Pacific coast of Guatemala by the late 1st century AD, or early 2nd century. Similarities between the Isthmian script and Early Maya script of the Pacific coast suggest that the two systems developed in tandem. By about AD 250, the Maya script had become a more formalised and consistent writing system.

The Catholic Church and colonial officials, notably Bishop Diego de Landa, destroyed Maya texts wherever they found them, and with them the knowledge of Maya writing, but by chance three uncontested pre-Columbian books dated to the Postclassic period have been preserved. These are known as the Madrid Codex, the Dresden Codex and the Paris Codex. A few pages survive from a fourth, the Grolier Codex, whose authenticity is disputed. Archaeology conducted at Maya sites often reveals other fragments, rectangular lumps of plaster and paint chips which were codices; these tantalizing remains are, however, too severely damaged for any inscriptions to have survived, most of the organic material having decayed. In reference to the few extant Maya writings, Michael D. Coe stated:

[O]ur knowledge of ancient Maya thought must represent only a tiny fraction of the whole picture, for of the thousands of books in which the full extent of their learning and ritual was recorded, only four have survived to modern times (as though all that posterity knew of ourselves were to be based upon three prayer books and 'Pilgrim's Progress').

— Michael D. Coe, The Maya, London: Thames and Hudson, 6th ed., 1999, pp. 199–200.

Most surviving pre-Columbian Maya writing dates to the Classic period and is contained in stone inscriptions from Maya sites, such as stelae, or on ceramics vessels. Other media include the aforementioned codices, stucco façades, frescoes, wooden lintels, cave walls, and portable artefacts crafted from a variety of materials, including bone, shell, obsidian, and jade.

Writing system

The Maya word Bʼalam ("jaguar") written twice in the Maya script. The first glyph writes the word logographicaly with the jaguar head standing for the entire word. The second glyph block writes the word phonetically using the three syllable signs BA, LA and MA.

The Maya writing system (often called hieroglyphs from a superficial resemblance to Ancient Egyptian writing) is a logosyllabic writing system, combining a syllabary of phonetic signs representing syllables with logogram representing entire words. Among the writing systems of the Pre-Columbian New World, Maya script most closely represents the spoken language. At any one time, no more than around 500 glyphs were in use, some 200 of which (including variations) were phonetic.

The Maya script was in use up to the arrival of the Europeans, its use peaking during the Classic Period. In excess of 10,000 individual texts have been recovered, mostly inscribed on stone monuments, lintels, stelae and ceramics. The Maya also produced texts painted on a form of paper manufactured from processed tree-bark generally now known by its Nahuatl-language name amatl used to produce codices. The skill and knowledge of Maya writing persisted among segments of the population right up to the Spanish conquest. The knowledge was subsequently lost, as a result of the impact of the conquest on Maya society.

The decipherment and recovery of the knowledge of Maya writing has been a long and laborious process. Some elements were first deciphered in the late 19th and early 20th century, mostly the parts having to do with numbers, the Maya calendar, and astronomy. Major breakthroughs were made from the 1950s to 1970s, and accelerated rapidly thereafter. By the end of the 20th century, scholars were able to read the majority of Maya texts, and ongoing work continues to further illuminate the content.

Logosyllabic script

Reading order of Maya hieroglyphic text

The basic unit of Maya logosyllabic text is the glyph block, which transcribes a word or phrase. The block is composed of one or more individual glyphs attached to each other to form the glyph block, with individual glyph blocks generally being separated by a space. Glyph blocks are usually arranged in a grid pattern. For ease of reference, epigraphers refer to glyph blocks from left to right alphabetically, and top to bottom numerically. Thus, any glyph block in a piece of text can be identified. C4 would be third block counting from the left, and the fourth block counting downwards. If a monument or artefact has more than one inscription, column labels are not repeated, rather they continue in the alphabetic series; if there are more than 26 columns, the labelling continues as A', B', etc. Numeric row labels restart from 1 for each discrete unit of text.

Although Mayan text may be laid out in varying manners, generally it is arranged into double columns of glyph blocks. The reading order of text starts at the top left (block A1), continues to the second block in the double-column (B1), then drops down a row and starts again from the left half of the double column (A2), and thus continues in zig-zag fashion. Once the bottom is reached, the inscription continues from the top left of the next double column. Where an inscription ends in a single (unpaired) column, this final column is usually read straight downwards.

Individual glyph blocks may be composed of a number of elements. These consist of the main sign, and any affixes. Main signs represent the major element of the block, and may be a noun, verb, adverb, adjective, or phonetic sign. Some main signs are abstract, some are pictures of the object they represent, and others are "head variants", personifications of the word they represent. Affixes are smaller rectangular elements, usually attached to a main sign, although a block may be composed entirely of affixes. Affixes may represent a wide variety of speech elements, including nouns, verbs, verbal suffixes, prepositions, pronouns, and more. Small sections of a main sign could be used to represent the whole main sign, and Maya scribes were highly inventive in their usage and adaptation of glyph elements.

Writing tools

Although the archaeological record does not provide examples of brushes or pens, analysis of ink strokes on the Postclassic codices suggests that it was applied with a brush with a tip fashioned from pliable hair. A Classic period sculpture from Copán, Honduras, depicts a scribe with an inkpot fashioned from a conch shell. Excavations at Aguateca uncovered a number of scribal artefacts from the residences of elite status scribes, including palettes and mortars and pestles.

Scribes and literacy

Commoners were illiterate; scribes were drawn from the elite. It is not known if all members of the aristocracy could read and write, although at least some women could, since there are representations of female scribes in Maya art. Maya scribes were called aj tzʼib, meaning "one who writes or paints". There were probably scribal schools where members of the aristocracy were taught to write. Scribal activity is identifiable in the archaeological record; Jasaw Chan Kʼawiil I, king of Tikal, was interred with his paint pot. Some junior members of the Copán royal dynasty have also been found buried with their writing implements. A palace at Copán has been identified as that of a noble lineage of scribes; it is decorated with sculpture that includes figures holding ink pots.

Although not much is known about Maya scribes, some did sign their work, both on ceramics and on stone sculpture. Usually, only a single scribe signed a ceramic vessel, but multiple sculptors are known to have recorded their names on stone sculpture; eight sculptors signed one stela at Piedras Negras. However, most works remained unsigned by their artists.

Mathematics

Maya numerals

In common with the other Mesoamerican civilizations, the Maya used a base 20 (vigesimal) system. The bar-and-dot counting system that is the base of Maya numerals was in use in Mesoamerica by 1000 BC; the Maya adopted it by the Late Preclassic, and added the symbol for zero. This may have been the earliest known occurrence of the idea of an explicit zero worldwide, although it may have been predated by the Babylonian system. The earliest explicit use of zero occurred on monuments dated to 357 AD. In its earliest uses, the zero served as a place holder, indicating an absence of a particular calendrical count. This later developed into a numeral that was used to perform calculation, and was used in hieroglyphic texts for more than a thousand years, until the writing system was extinguished by the Spanish.

The basic number system consists of a dot to represent one, and a bar to represent five. By the Postclassic period a shell symbol represented zero; during the Classic period other glyphs were used. The Maya numerals from 0 to 19 used repetitions of these symbols. The value of a numeral was determined by its position; as a numeral shifted upwards, its basic value multiplied by twenty. In this way, the lowest symbol would represent units, the next symbol up would represent multiples of twenty, and the symbol above that would represent multiples of 400, and so on. For example, the number 884 would be written with four dots on the lowest level, four dots on the next level up, and two dots on the next level after that, to give 4×1 + 4×20 + 2×400 = 884. Using this system, the Maya were able to record huge numbers. Simple addition could be performed by summing the dots and bars in two columns to give the result in a third column.

Calendar

The Maya calendrical system, in common with other Mesoamerican calendars, had its origins in the Preclassic period. However, it was the Maya that developed the calendar to its maximum sophistication, recording lunar and solar cycles, eclipses and movements of planets with great accuracy. In some cases, the Maya calculations were more accurate than equivalent calculations in the Old World; for example, the Maya solar year was calculated to greater accuracy than the Julian year. The Maya calendar was intrinsically tied to Maya ritual, and it was central to Maya religious practices. The calendar combined a non-repeating Long Count with three interlocking cycles, each measuring a progressively larger period. These were the 260-day tzolkʼin, the 365-day haabʼ, and the 52-year Calendar Round, resulting from the combination of the tzolkʼin with the haab'. There were also additional calendric cycles, such as an 819-day cycle associated with the four quadrants of Maya cosmology, governed by four different aspects of the god Kʼawiil.

The basic unit in the Maya calendar was one day, or kʼin, and 20 kʼin grouped to form a winal. The next unit, instead of being multiplied by 20, as called for by the vigesimal system, was multiplied by 18 in order to provide a rough approximation of the solar year (hence producing 360 days). This 360-day year was called a tun. Each succeeding level of multiplication followed the vigesimal system.

Long Count periods
Period Calculation Span Years (approx.)
kʼin 1 day 1 day
winal 1 x 20 20 days
tun 18 x 20 360 days 1 year
kʼatun 20 x 18 x 20 7,200 days 20 years
bakʼtun 20 x 18 x 20 x 20 144,000 days 394 years
piktun 20 x 18 x 20 x 20 x 20 2,880,000 days 7,885 years
kalabtun 20 x 18 x 20 x 20 x 20 x 20 57,600,000 days 157,700 years
kinchiltun 20 x 18 x 20 x 20 x 20 x 20 x 20 1,152,000,000 days 3,154,004 years
alawtun 20 x 18 x 20 x 20 x 20 x 20 x 20 x 20 23,040,000,000 days 63,080,082 years

The 260-day tzolkʼin provided the basic cycle of Maya ceremony, and the foundations of Maya prophecy. No astronomical basis for this count has been proved, and it may be that the 260-day count is based on the human gestation period. This is reinforced by the use of the tzolkʼin to record dates of birth, and provide corresponding prophecy. The 260-day cycle repeated a series of 20-day-names, with a number from 1 to 13 prefixed to indicated where in the cycle a particular day occurred.

The 365-day haab was produced by a cycle of eighteen named 20-day winals, completed by the addition of a 5-day period called the wayeb. The wayeb was considered to be a dangerous time, when the barriers between the mortal and supernatural realms were broken, allowing malignant deities to cross over and interfere in human concerns. In a similar way to the tzʼolkin, the named winal would be prefixed by a number (from 0 to 19), in the case of the shorter wayeb period, the prefix numbers ran 0 to 4. Since each day in the tzʼolkin had a name and number (e.g. 8 Ajaw), this would interlock with the haab, producing an additional number and name, to give any day a more complete designation, for example 8 Ajaw 13 Keh. Such a day name could only recur once every 52 years, and this period is referred to by Mayanists as the Calendar Round. In most Mesoamerican cultures, the Calendar Round was the largest unit for measuring time.

As with any non-repeating calendar, the Maya measured time from a fixed start point. The Maya set the beginning of their calendar as the end of a previous cycle of bakʼtuns, equivalent to a day in 3114 BC. This was believed by the Maya to be the day of the creation of the world in its current form. The Maya used the Long Count Calendar to fix any given day of the Calendar Round within their current great Piktun cycle consisting of either 20 bakʼtuns. There was some variation in the calendar, specifically texts in Palenque demonstrate that the piktun cycle that ended in 3114 BC had only 13 bakʼtuns, but others used a cycle of 13 + 20 bakʼtun in the current piktun. Additionally, there may have been some regional variation in how these exceptional cycles were managed.

A full long count date consisted of an introductory glyph followed by five glyphs counting off the number of bakʼtuns, katʼuns, tuns, winals, and kʼins since the start of the current creation. This would be followed by the tzʼolkin portion of the Calendar Round date, and after a number of intervening glyphs, the Long Count date would end with the Haab portion of the Calendar Round date.

Correlation of the Long Count calendar

Although the Calendar Round is still in use today, the Maya started using an abbreviated Short Count during the Late Classic period. The Short Count is a count of 13 kʼatuns. The Book of Chilam Balam of Chumayel contains the only colonial reference to classic long-count dates. The most generally accepted correlation is the Goodman-Martínez-Thompson, or GMT, correlation. This equates the Long Count date 11.16.0.0.0 13 Ajaw 8 Xul with the Gregorian date of 12 November 1539. Epigraphers Simon Martin and Nikolai Grube argue for a two-day shift from the standard GMT correlation. The Spinden Correlation would shift the Long Count dates back by 260 years; it also accords with the documentary evidence, and is better suited to the archaeology of the Yucatán Peninsula, but presents problems with the rest of the Maya region. The George Vaillant Correlation would shift all Maya dates 260 years later, and would greatly shorten the Postclassic period. Radiocarbon dating of dated wooden lintels at Tikal supports the GMT correlation.

Astronomy

The famous astrologer John Dee used an Aztec obsidian mirror to see into the future. We may look down our noses at his ideas, but one may be sure that in outlook he was far closer to a Maya priest astronomer than is an astronomer of our century.

Representation of an astronomer from the Madrid Codex

The Maya made meticulous observations of celestial bodies, patiently recording astronomical data on the movements of the sun, moon, Venus, and the stars. This information was used for divination, so Maya astronomy was essentially for astrological purposes. Although Maya astronomy was mainly used by the priesthood to comprehend past cycles of time, and project them into the future to produce prophecy, it also had some practical applications, such as providing aid in crop planting and harvesting. The priesthood refined observations and recorded eclipses of the sun and moon, and movements of Venus and the stars; these were measured against dated events in the past, on the assumption that similar events would occur in the future when the same astronomical conditions prevailed. Illustrations in the codices show that priests made astronomical observations using the naked eye, assisted by crossed sticks as a sighting device. Analysis of the few remaining Postclassic codices has revealed that, at the time of European contact, the Maya had recorded eclipse tables, calendars, and astronomical knowledge that was more accurate at that time than comparable knowledge in Europe.

The Maya measured the 584-day Venus cycle with an error of just two hours. Five cycles of Venus equated to eight 365-day haab calendrical cycles, and this period was recorded in the codices. The Maya also followed the movements of Jupiter, Mars and Mercury. When Venus rose as the Morning Star, this was associated with the rebirth of the Maya Hero Twins. For the Maya, the heliacal rising of Venus was associated with destruction and upheaval. Venus was closely associated with warfare, and the hieroglyph meaning "war" incorporated the glyph-element symbolizing the planet. Sight-lines through the windows of the Caracol building at Chichen Itza align with the northernmost and southernmost extremes of Venus' path. Maya rulers launched military campaigns to coincide with the heliacal or cosmical rising of Venus, and would also sacrifice important captives to coincide with such conjunctions.

Solar and lunar eclipses were considered to be especially dangerous events that could bring catastrophe upon the world. In the Dresden Codex, a solar eclipse is represented by a serpent devouring the kʼin ("day") hieroglyph. Eclipses were interpreted as the sun or moon being bitten, and lunar tables were recorded in order that the Maya might be able to predict them, and perform the appropriate ceremonies to ward off disaster.

Religion and mythology

In common with the rest of Mesoamerica, the Maya believed in a supernatural realm inhabited by an array of powerful deities who needed to be placated with ceremonial offerings and ritual practices. At the core of Maya religious practice was the worship of deceased ancestors, who would intercede for their living descendants in dealings with the supernatural realm. The earliest intermediaries between humans and the supernatural were shamans. Maya ritual included the use of hallucinogens for chilan, oracular priests. Visions for the chilan were likely facilitated by consumption of water lilies, which are hallucinogenic in high doses. As the Maya civilization developed, the ruling elite codified the Maya world view into religious cults that justified their right to rule. In the Late Preclassic, this process culminated in the institution of the divine king, the kʼuhul ajaw, endowed with ultimate political and religious power.

The Maya viewed the cosmos as highly structured. There were thirteen levels in the heavens and nine in the underworld, with the mortal world in between. Each level had four cardinal directions associated with a different colour; north was white, east was red, south was yellow, and west was black. Major deities had aspects associated with these directions and colours.

Maya households interred their dead underneath the floors, with offerings appropriate to the social status of the family. There the dead could act as protective ancestors. Maya lineages were patrilineal, so the worship of a prominent male ancestor would be emphasised, often with a household shrine. As Maya society developed, and the elite became more powerful, Maya royalty developed their household shrines into the great pyramids that held the tombs of their ancestors.

Belief in supernatural forces pervaded Maya life and influenced every aspect of it, from the simplest day-to-day activities such as food preparation, to trade, politics, and elite activities. Maya deities governed all aspects of the world, both visible and invisible. The Maya priesthood was a closed group, drawing its members from the established elite; by the Early Classic they were recording increasingly complex ritual information in their hieroglyphic books, including astronomical observations, calendrical cycles, history and mythology. The priests performed public ceremonies that incorporated feasting, bloodletting, incense burning, music, ritual dance, and, on certain occasions, human sacrifice. During the Classic period, the Maya ruler was the high priest, and the direct conduit between mortals and the gods. It is highly likely that, among commoners, shamanism continued in parallel to state religion. By the Postclassic, religious emphasis had changed; there was an increase in worship of the images of deities, and more frequent recourse to human sacrifice.

Archaeologists painstakingly reconstruct these ritual practices and beliefs using several techniques. One important, though incomplete, resource is physical evidence, such as dedicatory caches and other ritual deposits, shrines, and burials with their associated funerary offerings. Maya art, architecture, and writing are another resource, and these can be combined with ethnographic sources, including records of Maya religious practices made by the Spanish during the conquest.

Human sacrifice

Blood was viewed as a potent source of nourishment for the Maya deities, and the sacrifice of a living creature was a powerful blood offering. By extension, the sacrifice of a human life was the ultimate offering of blood to the gods, and the most important Maya rituals culminated in human sacrifice. Generally only high status prisoners of war were sacrificed, with lower status captives being used for labour.

Important rituals such as the dedication of major building projects or the enthronement of a new ruler required a human offering. The sacrifice of an enemy king was the most prized, and such a sacrifice involved decapitation of the captive ruler, perhaps in a ritual reenactment of the decapitation of the Maya maize god by the death gods. In AD 738, the vassal king Kʼakʼ Tiliw Chan Yopaat of Quiriguá captured his overlord, Uaxaclajuun Ubʼaah Kʼawiil of Copán and a few days later ritually decapitated him. Sacrifice by decapitation is depicted in Classic period Maya art, and sometimes took place after the victim was tortured, being variously beaten, scalped, burnt or disembowelled. Another myth associated with decapitation was that of the Hero Twins recounted in the Popol Vuh: playing a ballgame against the gods of the underworld, the heroes achieved victory, but one of each pair of twins was decapitated by their opponents.

During the Postclassic period, the most common form of human sacrifice was heart extraction, influenced by the rites of the Aztecs in the Valley of Mexico; this usually took place in the courtyard of a temple, or upon the summit of the pyramid. In one ritual, the corpse would be skinned by assistant priests, except for the hands and feet, and the officiating priest would then dress himself in the skin of the sacrificial victim and perform a ritual dance symbolizing the rebirth of life. Archaeological investigations indicate that heart sacrifice was practised as early as the Classic period.

Deities

The Maya world was populated by a great variety of deities, supernatural entities and sacred forces. The Maya had such a broad interpretation of the sacred that identifying distinct deities with specific functions is inaccurate. The Maya interpretation of deities was closely tied to the calendar, astronomy, and their cosmology. The importance of a deity, its characteristics, and its associations varied according to the movement of celestial bodies. The priestly interpretation of astronomical records and books was therefore crucial, since the priest would understand which deity required ritual propitiation, when the correct ceremonies should be performed, and what would be an appropriate offering. Each deity had four manifestations, associated with the cardinal directions, each identified with a different colour. They also had a dual day-night/life-death aspect.

Itzamna was the creator god, but he also embodied the cosmos, and was simultaneously a sun god; Kʼinich Ahau, the day sun, was one of his aspects. Maya kings frequently identified themselves with Kʼinich Ahau. Itzamna also had a night sun aspect, the Night Jaguar, representing the sun in its journey through the underworld. The four Pawatuns supported the corners of the mortal realm; in the heavens, the Bacabs performed the same function. As well as their four main aspects, the Bakabs had dozens of other aspects that are not well understood. The four Chaacs were storm gods, controlling thunder, lightning, and the rains. The nine lords of the night each governed one of the underworld realms. Other important deities included the moon goddess, the maize god, and the Hero Twins.

The Popol Vuh was written in the Latin script in early colonial times, and was probably transcribed from a hieroglyphic book by an unknown Kʼicheʼ Maya nobleman. It is one of the most outstanding works of indigenous literature in the Americas. The Popul Vuh recounts the mythical creation of the world, the legend of the Hero Twins, and the history of the Postclassic Kʼicheʼ kingdom. Deities recorded in the Popul Vuh include Hun Hunahpu, believed by some to be the Kʼicheʼ maize god, and a triad of deities led by the Kʼicheʼ patron Tohil, and also including the moon goddess Awilix, and the mountain god Jacawitz.

In common with other Mesoamerican cultures, the Maya worshipped feathered serpent deities. Such worship was rare during the Classic period, but by the Postclassic the feathered serpent had spread to both the Yucatán Peninsula and the Guatemalan Highlands. In Yucatán, the feathered serpent deity was Kukulkan, among the Kʼicheʼ it was Qʼuqʼumatz. Kukulkan had his origins in the Classic period War Serpent, Waxaklahun Ubah Kan, and has also been identified as the Postclassic version of the Vision Serpent of Classic Maya art. Although the cult of Kukulkan had its origins in these earlier Maya traditions, the worship of Kukulkan was heavily influenced by the Quetzalcoatl cult of central Mexico. Likewise, Qʼuqʼumatz had a composite origin, combining the attributes of Mexican Quetzalcoatl with aspects of the Classic period Itzamna.

Agriculture

Maize was a staple of the Maya diet.

The ancient Maya had diverse and sophisticated methods of food production. It was believed that shifting cultivation (swidden) agriculture provided most of their food, but it is now thought that permanent raised fields, terracing, intensive gardening, forest gardens, and managed fallows were also crucial to supporting the large populations of the Classic period in some areas. Indeed, evidence of these different agricultural systems persist today: raised fields connected by canals can be seen on aerial photographs. Contemporary rainforest species composition has significantly higher abundance of species of economic value to ancient Maya in areas that were densely populated in pre-Columbian times, and pollen records in lake sediments suggest that maize, manioc, sunflower seeds, cotton, and other crops have been cultivated in association with deforestation in Mesoamerica since at least 2500 BC.

The basic staples of the Maya diet were maize, beans, and squashes. These were supplemented with a wide variety of other plants either cultivated in gardens or gathered in the forest. At Joya de Cerén, a volcanic eruption preserved a record of foodstuffs stored in Maya homes, among them were chilies and tomatoes. Cotton seeds were in the process of being ground, perhaps to produce cooking oil. In addition to basic foodstuffs, the Maya also cultivated prestige crops such as cotton, cacao and vanilla. Cacao was especially prized by the elite, who consumed chocolate beverages. Cotton was spun, dyed, and woven into valuable textiles in order to be traded.

The Maya had few domestic animals; dogs were domesticated by 3000 BC, and the Muscovy duck by the Late Postclassic. Ocellated turkeys were unsuitable for domestication, but were rounded up in the wild and penned for fattening. All of these were used as food animals; dogs were additionally used for hunting. It is possible that deer were also penned and fattened.

Maya sites

There are hundreds of Maya sites spread across five countries: Belize, El Salvador, Guatemala, Honduras and Mexico. The six sites with particularly outstanding architecture or sculpture are Chichen Itza, Palenque, Uxmal, and Yaxchilan in Mexico, Tikal in Guatemala and Copán in Honduras. Other important, but difficult to reach, sites include Calakmul and El Mirador. The principal sites in the Puuc region, after Uxmal, are Kabah, Labna, and Sayil. In the east of the Yucatán Peninsula are Coba and the small site of Tulum. The Río Bec sites of the base of the peninsula include Becan, Chicanná, Kohunlich, and Xpuhil. The most noteworthy sites in Chiapas, other than Palenque and Yaxchilan, are Bonampak and Toniná. In the Guatemalan Highlands are Iximche, Kaminaljuyu, Mixco Viejo, and Qʼumarkaj (also known as Utatlán). In the northern Petén lowlands of Guatemala there are many sites, though apart from Tikal access is generally difficult. Some of the Petén sites are Dos Pilas, Seibal, and Uaxactún. Important sites in Belize include Altun Ha, Caracol, and Xunantunich.

Museum collections

There are many museums across the world with Maya artefacts in their collections. The Foundation for the Advancement of Mesoamerican Studies lists over 250 museums in its Maya Museum database, and the European Association of Mayanists lists just under 50 museums in Europe alone.

Bow and arrow

From Wikipedia, the free encyclopedia
https://en.wikipedia.org/wiki/Bow_and_arrow

The bow and arrow is a ranged weapon system consisting of an elastic launching device (bow) and long-shafted projectiles (arrows).

Archery is the art, practice, or skill of using bows to shoot arrows. A person who shoots arrows with a bow is called a bowman or an archer. Someone who makes bows is known as a bowyer, someone who makes arrows is a fletcher, and someone who manufactures metal arrowheads is an arrowsmith.

Humans used bows and arrows for hunting and aggression long before recorded history, and the practice was common to many prehistoric cultures. They were important weapons of war from ancient history until the early modern period, where they were rendered increasingly obsolete by the development of the more powerful and accurate firearms, and were eventually dropped from warfare. Today, bows and arrows are mostly used for hunting and sports.

Basic design and use

Drawing a bow, from a 1908 archery manual

A bow consists of a semi-rigid but elastic arc with a high-tensile bowstring joining the ends of the two limbs of the bow. An arrow is a projectile with a pointed tip and a long shaft with stabilizer fins (fletching) towards the back, with a narrow notch (nock) at the very end to contact the bowstring.

To load an arrow for shooting (nocking an arrow), the archer places an arrow across the middle of the bow with the bowstring in the arrow's nock. To shoot, the archer holds the bow at its center with one hand and pulls back (draws) the arrow and the bowstring with the other (typically the dominant hand). This flexes the two limbs of the bow rearwards, which perform the function of a pair of cantilever springs to store elastic energy.

Typically while maintaining the draw, the archer aims the shot intuitively or by sighting along the arrow. Then archer releases (looses) the draw, allowing the limbs' stored energy to convert into kinetic energy transmitted via the bowstring to the arrow, propelling it to fly forward with high velocity.

A container or bag for additional arrows for quick reloading is called a quiver.

When not in use, bows are generally kept unstrung, meaning one or both ends of the bowstring are detached from the bow. This removes all residual tension on the bow and can help prevent it from losing strength or elasticity over time. Many bow designs also let it straighten out more completely, reducing the space needed to store the bow. Returning the bowstring to its ready-to-use position is called stringing the bow.

History

Scythians shooting with bows, Panticapeum (modern Kertch), 4th century BCE.

The oldest known evidence of arrows comes from South African sites such as Sibudu Cave, where likely arrowheads have been found, dating from approximately 72,000–60,000 years ago.

In Eurasia, the bow and arrow reappears around the Upper Paleolithic. After the end of the last glacial period, use of the bow seems to have spread to every inhabited region, except for Australasia and most of Oceania.

The earliest probable arrowheads found outside of Africa were discovered in 2020 in Fa Hien Cave, Sri Lanka. It has been dated to 48,000 years ago. "Bow-and-arrow hunting at the Sri Lankan site likely focused on monkeys and smaller animals, such as squirrels, Langley says. Remains of these creatures were found in the same sediment as the bone points."

The earliest definite remains of bow and arrow from Europe are possible fragments from Germany found at Mannheim-Vogelstang dated 17,500–18,000 years ago, and at Stellmoor dated 11,000 years ago. Azilian points found in Grotte du Bichon, Switzerland, alongside the remains of both a bear and a hunter, with flint fragments found in the bear's third vertebra, suggest the use of arrows at 13,500 years ago.

At the site of Nataruk in Turkana County, Kenya, obsidian bladelets found embedded in a skull and within the thoracic cavity of another skeleton, suggest the use of stone-tipped arrows as weapons about 10,000 years ago.

The oldest extant bows in one piece are the elm Holmegaard bows from Denmark which were dated to 9,000 BCE. Several bows from Holmegaard, Denmark, date 8,000 years ago. High-performance wooden bows are currently made following the Holmegaard design. The Stellmoor bow fragments from northern Germany were dated to about 8,000 BCE, but they were destroyed in Hamburg during the Second World War, before carbon 14 dating was available; their age is attributed by archaeological association.

The bow was an important weapon for both hunting and warfare from prehistoric times until the widespread use of gunpowder weapons in the 16th century. It was also common in ancient warfare, although certain cultures would not favor them. Greek poet Archilocus expressed scorn for fighting with bows and slings.

Organised warfare with bows ended in the early to mid-17th century in Western Europe, but it persisted into the 19th century in Eastern cultures, including hunting and warfare in the New World. In the Canadian Arctic bows were made until the end of the 20th century for hunting caribou, for instance at Igloolik. The bow has more recently been used as a weapon of tribal warfare in some parts of Sub-Saharan Africa; an example was documented in 2009 in Kenya when Kisii people and Kalenjin people clashed, resulting in four deaths.

The British upper class led a revival of archery as a sport in the late 18th century. Sir Ashton Lever, an antiquarian and collector, formed the Toxophilite Society in London in 1781, under the patronage of George, then Prince of Wales.

Construction

Parts of the bow

The basic elements of a bow are a pair of curved elastic limbs, traditionally made from wood, joined by a riser. Both ends of the limbs are connected by a string known as the bow string. By pulling the string backwards the archer exerts compression force on the string-facing section, or belly, of the limbs as well as placing the outer section, or back, under tension. While the string is held, this stores the energy later released in putting the arrow to flight. The force required to hold the string stationary at full draw is often used to express the power of a bow, and is known as its draw weight, or weight. Other things being equal, a higher draw weight means a more powerful bow, which is able to project heavier arrows at the same velocity or the same arrow at a greater velocity.

The various parts of the bow can be subdivided into further sections. The topmost limb is known as the upper limb, while the bottom limb is the lower limb. At the tip of each limb is a nock, which is used to attach the bowstring to the limbs. The riser is usually divided into the grip, which is held by the archer, as well as the arrow rest and the bow window. The arrow rest is a small ledge or extension above the grip which the arrow rests upon while being aimed. The bow window is that part of the riser above the grip, which contains the arrow rest.

In bows drawn and held by hand, the maximum draw weight is determined by the strength of the archer. The maximum distance the string could be displaced and thus the longest arrow that could be loosed from it, a bow's draw length, is determined by the size of the archer.

A composite bow uses a combination of materials to create the limbs, allowing the use of materials specialized for the different functions of a bow limb. The classic composite bow uses wood for lightness and dimensional stability in the core, horn to store compression energy, and sinew for its ability to store energy in tension. Such bows, typically Asian, would often use a stiff end on the limb end, having the effect of a recurve. In this type of bow, this is known by the Arabic name 'siyah'.

Modern construction materials for bows include laminated wood, fiberglass, metals, and carbon fiber components.

Arrows

An arrow usually consists of a shaft with an arrowhead attached to the front end, with fletchings and a nock at the other. Modern arrows are usually made from carbon fibre, aluminum, fiberglass, and wood shafts. Carbon shafts have the advantage that they do not bend or warp, but they can often be too light weight to shoot from some bows and are expensive. Aluminum shafts are less expensive than carbon shafts, but they can bend and warp from use. Wood shafts are the least expensive option but often will not be identical in weight and size to each other and break more often than the other types of shafts. Arrow sizes vary greatly across cultures and range from very short ones that require the use of special equipment to be shot to ones in use in the Amazon River jungles that are 2.6 m (8.5 feet) long. Most modern arrows are 55 to 75 cm (22 to 30 inches) in length.

Arrows come in many types, among which are breasted, bob-tailed, barreled, clout, and target. A breasted arrow is thickest at the area right behind the fletchings, and tapers towards the (nock) and head. A bob-tailed arrow is thickest right behind the head, and tapers to the nock. A barrelled arrow is thickest in the centre of the arrow. Target arrows are those arrows used for target shooting rather than warfare or hunting, and usually have simple arrowheads.

For safety reasons, a bow should never be shot without an arrow nocked; without an arrow, the energy that is normally transferred into the projectile is instead directed back into the bow itself, which will cause damage to the bow's limbs.

Arrowheads

The end of the arrow that is designed to hit the target is called the arrowhead. Usually, these are separate items that are attached to the arrow shaft by either tangs or sockets. Materials used in the past for arrowheads include flint, bone, horn, or metal. Most modern arrowheads are made of steel, but wood and other traditional materials are still used occasionally. A number of different types of arrowheads are known, with the most common being bodkins, broadheads, and piles. Bodkin heads are simple spikes made of metal of various shapes, designed to pierce armour. A broadhead arrowhead is usually triangular or leaf-shaped and has a sharpened edge or edges. Broadheads are commonly used for hunting. A pile arrowhead is a simple metal cone, either sharpened to a point or somewhat blunt, that is used mainly for target shooting. A pile head is the same diameter as the arrow shaft and is usually just fitted over the tip of the arrow. Other heads are known, including the blunt head, which is flat at the end and is used for hunting small game or birds, and is designed to not pierce the target nor embed itself in trees or other objects and make recovery difficult. Another type of arrowhead is a barbed head, usually used in warfare or hunting.

Bowstrings

Bowstrings may have a nocking point marked on them, which serves to mark where the arrow is fitted to the bowstring before shooting. The area around the nocking point is usually bound with thread to protect the area around the nocking point from wear by the archer's hands. This section is called the serving. At one end of the bowstring a loop is formed, which is permanent. The other end of the bowstring also has a loop, but this is not permanently formed into the bowstring but is constructed by tying a knot into the string to form a loop. Traditionally this knot is known as the archer's knot, but is a form of the timber hitch. The knot can be adjusted to lengthen or shorten the bowstring. The adjustable loop is known as the "tail". The string is often twisted (this being called the "flemish twist").

Bowstrings have been constructed of many materials throughout history, including fibres such as flax, silk, and hemp. Other materials used were animal guts, animal sinews, and rawhide. Modern fibres such as Dacron or Kevlar are now used in commercial bowstring construction, as well as steel wires in some compound bows. Compound bows have a mechanical system of pulley cams over which the bowstring is wound. Nylon is useful only in emergency situations, as it stretches too much.

Types of bow

There is no single accepted system of classification of bows. Bows may be described by various characteristics including the materials used, the length of the draw that they permit, the shape of the bow in sideways view, and the shape of the limb in cross-section.

Commonly-used descriptors for bows include:

By side profile

  • Recurve bow: a bow with the tips curving away from the archer. The curves straighten out as the bow is drawn and the return of the tip to its curved state after release of the arrow adds extra velocity to the arrow.
  • Reflex bow: a bow whose entire limbs curve away from the archer when unstrung. The curves are opposite to the direction in which the bow flexes while drawn.

By material

By cross-section of limb

  • Longbow: a self bow with limbs rounded in cross-section, about the same height as the archer so as to allow a full draw, usually over 1.5 m (5 feet) long. The traditional English longbow was usually made of yew wood, but other woods are also used.
  • Flatbow: the limbs are approximately rectangular in cross-section. This was traditional in many Native American societies and was found to be the most efficient shape for bow limbs by American engineers in the 20th century.

Other characteristics

  • Takedown bow: a bow that can be disassembled for transportation, usually consisting of three parts: two limbs and a riser, in addition to the string.
  • Compound bow: a bow with mechanical amplifiers to aid with drawing the bowstring. Usually, these amplifiers are asymmetric pulleys called cams (though they are not actually cams) at the ends of the limbs, which provide a mechanical advantage (known as the let-off) while holding the bow in full draw. Such bows typically have high draw weights and are usually drawn with a release aid with a trigger mechanism for a consistently clean release.
  • Crossbow: a bow mounted horizontally on a frame similar to a firearm stock, which has a locking mechanism for holding the bowstring at full draw. Crossbows typically shoot arrow-like darts called bolts or "quarrels", rather than normal arrows.
  • Footbow: a bow meant to be used with the legs and arms while lying down and used in the current distance record for the furthest arrow shot.

 

Academic publishing

From Wikipedia, the free encyclopedia
Scientific and technical journal publications per million residents (2013)

Academic publishing is the subfield of publishing which distributes academic research and scholarship. Most academic work is published in academic journal articles, books or theses. The part of academic written output that is not formally published but merely printed up or posted on the Internet is often called "grey literature". Most scientific and scholarly journals, and many academic and scholarly books, though not all, are based on some form of peer review or editorial refereeing to qualify texts for publication. Peer review quality and selectivity standards vary greatly from journal to journal, publisher to publisher, and field to field.

Most established academic disciplines have their own journals and other outlets for publication, although many academic journals are somewhat interdisciplinary, and publish work from several distinct fields or subfields. There is also a tendency for existing journals to divide into specialized sections as the field itself becomes more specialized. Along with the variation in review and publication procedures, the kinds of publications that are accepted as contributions to knowledge or research differ greatly among fields and subfields. In the sciences, the desire for statistically significant results leads to publication bias.

Academic publishing is undergoing major changes, as it makes the transition from the print to the electronic format. Business models are different in the electronic environment. Since the early 1990s, licensing of electronic resources, particularly journals, has been very common. An important trend, particularly with respect to journals in the sciences, is open access via the Internet. In open access publishing, a journal article is made available free for all on the web by the publisher at the time of publication. Both open and closed journals are sometimes funded by the author paying an article processing charge, thereby shifting some fees from the reader to the researcher or their funder. Many open or closed journals fund their operations without such fees and others use them in predatory publishing. The Internet has facilitated open access self-archiving, in which authors themselves make a copy of their published articles available free for all on the web. Some important results in mathematics have been published only on arXiv.

History

The Journal des sçavans (later spelled Journal des savants), established by Denis de Sallo, was the earliest academic journal published in Europe. Its content included obituaries of famous men, church history, and legal reports. The first issue appeared as a twelve-page quarto pamphlet on Monday, 5 January 1665, shortly before the first appearance of the Philosophical Transactions of the Royal Society, on 6 March 1665.

At that time, the act of publishing academic inquiry was controversial and widely ridiculed. It was not at all unusual for a new discovery to be announced as a monograph, reserving priority for the discoverer, but indecipherable for anyone not in on the secret: both Isaac Newton and Leibniz used this approach. However, this method did not work well. Robert K. Merton, a sociologist, found that 92% of cases of simultaneous discovery in the 17th century ended in dispute. The number of disputes dropped to 72% in the 18th century, 59% by the latter half of the 19th century, and 33% by the first half of the 20th century. The decline in contested claims for priority in research discoveries can be credited to the increasing acceptance of the publication of papers in modern academic journals, with estimates suggesting that around 50 million journal articles have been published since the first appearance of the Philosophical Transactions. The Royal Society was steadfast in its not-yet-popular belief that science could only move forward through a transparent and open exchange of ideas backed by experimental evidence.

Early scientific journals embraced several models: some were run by a single individual who exerted editorial control over the contents, often simply publishing extracts from colleagues' letters, while others employed a group decision-making process, more closely aligned to modern peer review. It wasn't until the middle of the 20th century that peer review became the standard.

The Impact of the COVID-19 Pandemic on Scientific Publishing

The COVID-19 pandemic hijacked the entire world of basic and clinical science, with unprecedented shifts in funding priorities worldwide and a boom in medical publishing, accompanied by an unprecedented increase in the number of publications. Preprints servers become much popular during the pandemic, the Covid situation has an impact also on traditional peer-review.

Covid has deepened the wests monopoly of science-publishing, "by August 2021, at least 210,000 new papers on covid-19 had been published, according to a Royal Society study. Of the 720,000-odd authors of these papers, nearly 270,000 were from the US, the UK, Italy or Spain."

Publishers and business aspects

In the 1960s and 1970s, commercial publishers began to selectively acquire "top-quality" journals that were previously published by nonprofit academic societies. When the commercial publishers raised the subscription prices significantly, they lost little of the market, due to the inelastic demand for these journals. Although there are over 2,000 publishers, five for-profit companies (Reed Elsevier, Springer Science+Business Media, Wiley-Blackwell, Taylor & Francis, and Sage) accounted for 50% of articles published in 2013. (Since 2013, Springer Science+Business Media has undergone a merger to form an even bigger company named Springer Nature.) Available data indicate that these companies have profit margins of around 40% making it one of the most profitable industries, especially compared to the smaller publishers, which likely operate with low margins. These factors have contributed to the "serials crisis" – total expenditures on serials increased 7.6% per year from 1986 to 2005, yet the number of serials purchased increased an average of only 1.9% per year.

Unlike most industries, in academic publishing the two most important inputs are provided "virtually free of charge". These are the articles and the peer review process. Publishers argue that they add value to the publishing process through support to the peer review group, including stipends, as well as through typesetting, printing, and web publishing. Investment analysts, however, have been skeptical of the value added by for-profit publishers, as exemplified by a 2005 Deutsche Bank analysis which stated that "we believe the publisher adds relatively little value to the publishing process... We are simply observing that if the process really were as complex, costly and value-added as the publishers protest that it is, 40% margins wouldn't be available."

Crisis

A crisis in academic publishing is "widely perceived"; the apparent crisis has to do with the combined pressure of budget cuts at universities and increased costs for journals (the serials crisis). The university budget cuts have reduced library budgets and reduced subsidies to university-affiliated publishers. The humanities have been particularly affected by the pressure on university publishers, which are less able to publish monographs when libraries can not afford to purchase them. For example, the ARL found that in "1986, libraries spent 44% of their budgets on books compared with 56% on journals; twelve years later, the ratio had skewed to 28% and 72%." Meanwhile, monographs are increasingly expected for tenure in the humanities. In 2002 the Modern Language Association expressed hope that electronic publishing would solve the issue.

In 2009 and 2010, surveys and reports found that libraries faced continuing budget cuts, with one survey in 2009 finding that 36% of UK libraries had their budgets cut by 10% or more, compared to 29% with increased budgets. In the 2010s, libraries began more aggressive cost cutting with the leverage of open access and open data. Data analysis with open source tools like Unpaywall Journals empowered library systems in reducing their subscription costs by 70% with the cancellation of the big deal with publishers like Elsevier.

Academic journal publishing reform

Several models are being investigated, such as open publication models or adding community-oriented features. It is also considered that "Online scientific interaction outside the traditional journal space is becoming more and more important to academic communication". In addition, experts have suggested measures to make the publication process more efficient in disseminating new and important findings by evaluating the worthiness of publication on the basis of the significance and novelty of the research finding.

Scholarly paper

In academic publishing, a paper is an academic work that is usually published in an academic journal. It contains original research results or reviews existing results. Such a paper, also called an article, will only be considered valid if it undergoes a process of peer review by one or more referees (who are academics in the same field) who check that the content of the paper is suitable for publication in the journal. A paper may undergo a series of reviews, revisions, and re-submissions before finally being accepted or rejected for publication. This process typically takes several months. Next, there is often a delay of many months (or in some fields, over a year) before an accepted manuscript appears. This is particularly true for the most popular journals where the number of accepted articles often outnumbers the space for printing. Due to this, many academics self-archive a 'preprint' or 'postprint' copy of their paper for free download from their personal or institutional website.

Some journals, particularly newer ones, are now published in electronic form only. Paper journals are now generally made available in electronic form as well, both to individual subscribers, and to libraries. Almost always these electronic versions are available to subscribers immediately upon publication of the paper version, or even before; sometimes they are also made available to non-subscribers, either immediately (by open access journals) or after an embargo of anywhere from two to twenty-four months or more, in order to protect against loss of subscriptions. Journals having this delayed availability are sometimes called delayed open access journals. Ellison in 2011 reported that in economics the dramatic increase in opportunities to publish results online has led to a decline in the use of peer-reviewed articles.

Categories of papers

An academic paper typically belongs to some particular category such as:

Note: Law review is the generic term for a journal of legal scholarship in the United States, often operating by rules radically different from those for most other academic journals.

Peer review

Peer review is a central concept for most academic publishing; other scholars in a field must find a work sufficiently high in quality for it to merit publication. A secondary benefit of the process is an indirect guard against plagiarism since reviewers are usually familiar with the sources consulted by the author(s). The origins of routine peer review for submissions dates to 1752 when the Royal Society of London took over official responsibility for Philosophical Transactions. However, there were some earlier examples.

While journal editors largely agree the system is essential to quality control in terms of rejecting poor quality work, there have been examples of important results that are turned down by one journal before being taken to others. Rena Steinzor wrote:

Perhaps the most widely recognized failing of peer review is its inability to ensure the identification of high-quality work. The list of important scientific papers that were initially rejected by peer-reviewed journals goes back at least as far as the editor of Philosophical Transaction's 1796 rejection of Edward Jenner's report of the first vaccination against smallpox.

"Confirmatory bias" is the unconscious tendency to accept reports which support the reviewer's views and to downplay those which do not. Experimental studies show the problem exists in peer reviewing.

There are various types of peer review feedback that may be given prior to publication, including but not limited to:

  • Single-blind peer review
  • Double-blind peer review
  • Open peer review

Publishing process

The process of academic publishing, which begins when authors submit a manuscript to a publisher, is divided into two distinct phases: peer review and production.

The process of peer review is organized by the journal editor and is complete when the content of the article, together with any associated images, data, and supplementary material are accepted for publication. The peer review process is increasingly managed online, through the use of proprietary systems, commercial software packages, or open source and free software. A manuscript undergoes one or more rounds of review; after each round, the author(s) of the article modify their submission in line with the reviewers' comments; this process is repeated until the editor is satisfied and the work is accepted.

The production process, controlled by a production editor or publisher, then takes an article through copy editing, typesetting, inclusion in a specific issue of a journal, and then printing and online publication. Academic copy editing seeks to ensure that an article conforms to the journal's house style, that all of the referencing and labelling is correct, and that the text is consistent and legible; often this work involves substantive editing and negotiating with the authors. Because the work of academic copy editors can overlap with that of authors' editors, editors employed by journal publishers often refer to themselves as “manuscript editors”. During this process, copyright is often transferred from the author to the publisher.

In much of the 20th century, such articles were photographed for printing into proceedings and journals, and this stage was known as camera-ready copy. With modern digital submission in formats such as PDF, this photographing step is no longer necessary, though the term is still sometimes used.

The author will review and correct proofs at one or more stages in the production process. The proof correction cycle has historically been labour-intensive as handwritten comments by authors and editors are manually transcribed by a proof reader onto a clean version of the proof. In the early 21st century, this process was streamlined by the introduction of e-annotations in Microsoft Word, Adobe Acrobat, and other programs, but it still remained a time-consuming and error-prone process. The full automation of the proof correction cycles has only become possible with the onset of online collaborative writing platforms, such as Authorea, Google Docs, and various others, where a remote service oversees the copy-editing interactions of multiple authors and exposes them as explicit, actionable historic events. At the end of this process, a final version of record is published.

Citations

Academic authors cite sources they have used, in order to support their assertions and arguments and to help readers find more information on the subject. It also gives credit to authors whose work they use and helps avoid plagiarism. The topic of dual publication (also known as self-plagiarism) has been addressed by the Committee on Publication Ethics (COPE), as well as in the research literature itself.

Each scholarly journal uses a specific format for citations (also known as references). Among the most common formats used in research papers are the APA, CMS, and MLA styles.

The American Psychological Association (APA) style is often used in the social sciences. The Chicago Manual of Style (CMS) is used in business, communications, economics, and social sciences. The CMS style uses footnotes at the bottom of page to help readers locate the sources. The Modern Language Association (MLA) style is widely used in the humanities.

Publishing by discipline

Natural sciences

Scientific, technical, and medical (STM) literature is a large industry which generated $23.5 billion in revenue; $9.4 billion of that was specifically from the publication of English-language scholarly journals. Most scientific research is initially published in scientific journals and considered to be a primary source. Technical reports, for minor research results and engineering and design work (including computer software), round out the primary literature. Secondary sources in the sciences include articles in review journals (which provide a synthesis of research articles on a topic to highlight advances and new lines of research), and books for large projects, broad arguments, or compilations of articles. Tertiary sources might include encyclopedias and similar works intended for broad public consumption or academic libraries.

A partial exception to scientific publication practices is in many fields of applied science, particularly that of U.S. computer science research. An equally prestigious site of publication within U.S. computer science are some academic conferences. Reasons for this departure include a large number of such conferences, the quick pace of research progress, and computer science professional society support for the distribution and archiving of conference proceedings.

Social sciences

Publishing in the social sciences is very different in different fields. Some fields, like economics, may have very "hard" or highly quantitative standards for publication, much like the natural sciences. Others, like anthropology or sociology, emphasize field work and reporting on first-hand observation as well as quantitative work. Some social science fields, such as public health or demography, have significant shared interests with professions like law and medicine, and scholars in these fields often also publish in professional magazines.

Humanities

Publishing in the humanities is in principle similar to publishing elsewhere in the academy; a range of journals, from general to extremely specialized, are available, and university presses issue many new humanities books every year. The arrival of online publishing opportunities has radically transformed the economics of the field and the shape of the future is controversial. Unlike science, where timeliness is critically important, humanities publications often take years to write and years more to publish. Unlike the sciences, research is most often an individual process and is seldom supported by large grants. Journals rarely make profits and are typically run by university departments.

The following describes the situation in the United States. In many fields, such as literature and history, several published articles are typically required for a first tenure-track job, and a published or forthcoming book is now often required before tenure. Some critics complain that this de facto system has emerged without thought to its consequences; they claim that the predictable result is the publication of much shoddy work, as well as unreasonable demands on the already limited research time of young scholars. To make matters worse, the circulation of many humanities journals in the 1990s declined to almost untenable levels, as many libraries cancelled subscriptions, leaving fewer and fewer peer-reviewed outlets for publication; and many humanities professors' first books sell only a few hundred copies, which often does not pay for the cost of their printing. Some scholars have called for a publication subvention of a few thousand dollars to be associated with each graduate student fellowship or new tenure-track hire, in order to alleviate the financial pressure on journals.

Open access journals

Under Open Access, the content can be freely accessed and reused by anyone in the world using an Internet connection. The terminology going back to Budapest Open Access Initiative, Berlin Declaration on Open Access to Knowledge in the Sciences and Humanities, and Bethesda Statement on Open Access Publishing. The impact of the work available as Open Access is maximised because, quoting the Library of Trinity College Dublin:

  • Potential readership of Open Access material is far greater than that for publications where the full-text is restricted to subscribers.
  • Details of contents can be read by specialised web harvesters.
  • Details of contents also appear in normal search engines like Google, Google Scholar, Yahoo, etc.

Open Access is often confused with specific funding models such as Article Processing Charges (APC) being paid by authors or their funders, sometimes misleadingly called "open access model". The reason this term is misleading is due to the existence of many other models, including funding sources listed in the original the Budapest Open Access Initiative Declaration: "the foundations and governments that fund research, the universities and laboratories that employ researchers, endowments set up by discipline or institution, friends of the cause of open access, profits from the sale of add-ons to the basic texts, funds freed up by the demise or cancellation of journals charging traditional subscription or access fees, or even contributions from the researchers themselves". For more recent open public discussion of open access funding models, see Flexible membership funding model for Open Access publishing with no author-facing charges.

Prestige journals using the APC model often charge several thousand dollars. Oxford University Press, with over 300 journals, has fees ranging from £1000-£2500, with discounts of 50% to 100% to authors from developing countries. Wiley Blackwell has 700 journals available, and they charge different amounts for each journal. Springer, with over 2600 journals, charges US$3000 or EUR 2200 (excluding VAT).

The online distribution of individual articles and academic journals then takes place without charge to readers and libraries. Most open access journals remove all the financial, technical, and legal barriers that limit access to academic materials to paying customers. The Public Library of Science and BioMed Central are prominent examples of this model.

Fee-based open access publishing has been criticized on quality grounds, as the desire to maximize publishing fees could cause some journals to relax the standard of peer review. Although, similar desire is also present in the subscription model, where publishers increase numbers or published articles in order to justify raising their fees. It may be criticized on financial grounds as well because the necessary publication or subscription fees have proven to be higher than originally expected. Open access advocates generally reply that because open access is as much based on peer reviewing as traditional publishing, the quality should be the same (recognizing that both traditional and open access journals have a range of quality). It has also been argued that good science done by academic institutions who cannot afford to pay for open access might not get published at all, but most open access journals permit the waiver of the fee for financial hardship or authors in underdeveloped countries. In any case, all authors have the option of self-archiving their articles in their institutional repositories or disciplinary repositories in order to make them open access, whether or not they publish them in a journal.

If they publish in a Hybrid open access journal, authors or their funders pay a subscription journal a publication fee to make their individual article open access. The other articles in such hybrid journals are either made available after a delay or remain available only by subscription. Most traditional publishers (including Wiley-Blackwell, Oxford University Press, and Springer Science+Business Media) have already introduced such a hybrid option, and more are following. The fraction of the authors of a hybrid open access journal that makes use of its open access option can, however, be small. It also remains unclear whether this is practical in fields outside the sciences, where there is much less availability of outside funding. In 2006, several funding agencies, including the Wellcome Trust and several divisions of the Research Councils in the UK announced the availability of extra funding to their grantees for such open access journal publication fees.

In May 2016, the Council for the European Union agreed that from 2020 all scientific publications as a result of publicly funded research must be freely available. It also must be able to optimally reuse research data. To achieve that, the data must be made accessible, unless there are well-founded reasons for not doing so, for example, intellectual property rights or security or privacy issues.

Growth

In recent decades there has been a growth in academic publishing in developing countries as they become more advanced in science and technology. Although the large majority of scientific output and academic documents are produced in developed countries, the rate of growth in these countries has stabilized and is much smaller than the growth rate in some of the developing countries. The fastest scientific output growth rate over the last two decades has been in the Middle East and Asia with Iran leading with an 11-fold increase followed by the Republic of Korea, Turkey, Cyprus, China, and Oman. In comparison, the only G8 countries in top 20 ranking with fastest performance improvement are, Italy which stands at tenth and Canada at 13th globally.

By 2004, it was noted that the output of scientific papers originating from the European Union had a larger share of the world's total from 36.6% to 39.3% and from 32.8% to 37.5% of the "top one per cent of highly cited scientific papers". However, the United States' output dropped from 52.3% to 49.4% of the world's total, and its portion of the top one percent dropped from 65.6% to 62.8%.

Iran, China, India, Brazil, and South Africa were the only developing countries among the 31 nations that produced 97.5% of the most cited scientific articles in a study published in 2004. The remaining 162 countries contributed less than 2.5%. The Royal Society in a 2011 report stated that in share of English scientific research papers the United States was first followed by China, the UK, Germany, Japan, France, and Canada. The report predicted that China would overtake the United States sometime before 2020, possibly as early as 2013. China's scientific impact, as measured by other scientists citing the published papers the next year, is smaller although also increasing.

Role for publishers in scholarly communication

There is increasing frustration amongst OA advocates, with what is perceived as resistance to change on the part of many of the established academic publishers. Publishers are often accused of capturing and monetising publicly-funded research, using free academic labour for peer review, and then selling the resulting publications back to academia at inflated profits. Such frustrations sometimes spill over into hyperbole, of which "publishers add no value" is one of the most common examples.

However, scholarly publishing is not a simple process, and publishers do add value to scholarly communication as it is currently designed. Kent Anderson maintains a list of things that journal publishers do which currently contains 102 items and has yet to be formally contested from anyone who challenges the value of publishers. Many items on the list could be argued to be of value primarily to the publishers themselves, e.g. "Make money and remain a constant in the system of scholarly output". However, others provide direct value to researchers and research in steering the academic literature. This includes arbitrating disputes (e.g. over ethics, authorship), stewarding the scholarly record, copy-editing, proofreading, type-setting, styling of materials, linking the articles to open and accessible datasets, and (perhaps most importantly) arranging and managing scholarly peer review. The latter is a task that should not be underestimated as it effectively entails coercing busy people into giving their time to improve someone else's work and maintain the quality of the literature. Not to mention the standard management processes for large enterprises, including infrastructure, people, security, and marketing. All of these factors contribute in one way or another to maintaining the scholarly record.

It could be questioned though, whether these functions are actually necessary to the core aim of scholarly communication, namely, dissemination of research to researchers and other stakeholders such as policy makers, economic, biomedical and industrial practitioners as well as the general public. Above, for example, we question the necessity of the current infrastructure for peer review, and if a scholar-led crowdsourced alternative may be preferable. In addition, one of the biggest tensions in this space is associated with the question if for-profit companies (or the private sector) should be allowed to be in charge of the management and dissemination of academic output and execute their powers while serving, for the most part, their own interests. This is often considered alongside the value added by such companies, and therefore the two are closely linked as part of broader questions on appropriate expenditure of public funds, the role of commercial entities in the public sector, and issues around the privatisation of scholarly knowledge.

Publishing could certainly be done at a lower cost than common at present. There are significant researcher-facing inefficiencies in the system including the common scenario of multiple rounds of rejection and resubmission to various venues as well as the fact that some publishers profit beyond reasonable scale. What is missing most from the current publishing market, is transparency about the nature and the quality of the services publishers offer. This would allow authors to make informed choices, rather than decisions based on indicators that are unrelated to research quality, such as the JIF. All the above questions are being investigated and alternatives could be considered and explored. Yet, in the current system, publishers still play a role in managing processes of quality assurance, interlinking and findability of research. As the role of scholarly publishers within the knowledge communication industry continues to evolve, it is seen as necessary that they can justify their operation based on the intrinsic value that they add, and combat the perception that they add no value to the process.
