Renaissance

From Wikipedia, the free encyclopedia
 
Florence, the birthplace of the European Renaissance. The architectural perspective, and modern systems and fields of banking and accounting were introduced during the Renaissance.

The Renaissance is a term used to describe a period in European history marking the transition from the Middle Ages to modernity and covering the 15th and 16th centuries. It occurred after the Crisis of the Late Middle Ages and was associated with great social change. In addition to the standard periodization, proponents of a "long Renaissance" may put its beginning in the 14th century and its end in the 17th century. The traditional view focuses more on the early modern aspects of the Renaissance and argues that it was a break from the past, but many historians today focus more on its medieval aspects and argue that it was an extension of the Middle Ages.

The intellectual basis of the Renaissance was its version of humanism, derived from the concept of Roman humanitas and the rediscovery of classical Greek philosophy, such as that of Protagoras, who said that "man is the measure of all things". This new thinking became manifest in art, architecture, politics, science and literature. Early examples were the development of perspective in oil painting and the revived knowledge of how to make concrete. Although the invention of metal movable type sped the dissemination of ideas from the later 15th century, the changes of the Renaissance were not uniform across Europe: the first traces appear in Italy as early as the late 13th century, in particular with the writings of Dante and the paintings of Giotto.

As a cultural movement, the Renaissance encompassed innovative flowering of Latin and vernacular literatures, beginning with the 14th-century resurgence of learning based on classical sources, which contemporaries credited to Petrarch; the development of linear perspective and other techniques of rendering a more natural reality in painting; and gradual but widespread educational reform. In politics, the Renaissance contributed to the development of the customs and conventions of diplomacy, and in science to an increased reliance on observation and inductive reasoning. Although the Renaissance saw revolutions in many intellectual and social scientific pursuits, as well as the introduction of modern banking and the field of accounting, it is perhaps best known for its artistic developments and the contributions of such polymaths as Leonardo da Vinci and Michelangelo, who inspired the term "Renaissance man".

The Renaissance began in the Republic of Florence, one of the many states of Italy. Various theories have been proposed to account for its origins and characteristics, focusing on a variety of factors including the social and civic peculiarities of Florence at the time: its political structure, the patronage of its dominant family, the Medici, and the migration of Greek scholars and their texts to Italy following the Fall of Constantinople to the Ottoman Turks. Other major centres were northern Italian city-states such as Venice, Genoa, Milan, Bologna, and Rome during the Renaissance Papacy or Belgian cities such as Bruges, Ghent, Brussels, Leuven, or Antwerp.

The Renaissance has a long and complex historiography, and, in line with general scepticism of discrete periodizations, there has been much debate among historians reacting to the 19th-century glorification of the "Renaissance" and individual cultural heroes as "Renaissance men", questioning the usefulness of Renaissance as a term and as a historical delineation. Some observers have called into question whether the Renaissance was a cultural "advance" from the Middle Ages, instead seeing it as a period of pessimism and nostalgia for classical antiquity, while social and economic historians, especially of the longue durée, have instead focused on the continuity between the two eras, which are linked, as Panofsky observed, "by a thousand ties".

The term rinascita ('rebirth') first appeared in Giorgio Vasari's Lives of the Artists (c. 1550), anglicized as the Renaissance in the 1830s. The word has also been extended to other historical and cultural movements, such as the Carolingian Renaissance (8th and 9th centuries), Ottonian Renaissance (10th and 11th century), and the Renaissance of the 12th century.

Overview

The Renaissance was a cultural movement that profoundly affected European intellectual life in the early modern period. Beginning in Italy, and spreading to the rest of Europe by the 16th century, its influence was felt in art, architecture, philosophy, literature, music, science, technology, politics, religion, and other aspects of intellectual inquiry. Renaissance scholars employed the humanist method in study, and searched for realism and human emotion in art.

Renaissance humanists such as Poggio Bracciolini sought out in Europe's monastic libraries the Latin literary, historical, and oratorical texts of antiquity, while the Fall of Constantinople (1453) generated a wave of émigré Greek scholars bringing precious manuscripts in ancient Greek, many of which had fallen into obscurity in the West. It is in their new focus on literary and historical texts that Renaissance scholars differed so markedly from the medieval scholars of the Renaissance of the 12th century, who had focused on studying Greek and Arabic works of natural sciences, philosophy and mathematics, rather than on such cultural texts.

In the revival of neoplatonism Renaissance humanists did not reject Christianity; quite the contrary, many of the greatest works of the Renaissance were devoted to it, and the Church patronized many works of Renaissance art. However, a subtle shift took place in the way that intellectuals approached religion that was reflected in many other areas of cultural life. In addition, many Greek Christian works, including the Greek New Testament, were brought back from Byzantium to Western Europe and engaged Western scholars for the first time since late antiquity. This new engagement with Greek Christian works, and particularly the return to the original Greek of the New Testament promoted by humanists Lorenzo Valla and Erasmus, would help pave the way for the Protestant Reformation.

Well after the first artistic return to classicism had been exemplified in the sculpture of Nicola Pisano, Florentine painters led by Masaccio strove to portray the human form realistically, developing techniques to render perspective and light more naturally. Political philosophers, most famously Niccolò Machiavelli, sought to describe political life as it really was, that is to understand it rationally. A critical contribution to Italian Renaissance humanism, Giovanni Pico della Mirandola wrote the famous text De hominis dignitate (Oration on the Dignity of Man, 1486), which consists of a series of theses on philosophy, natural thought, faith and magic defended against any opponent on the grounds of reason. In addition to studying classical Latin and Greek, Renaissance authors also began increasingly to use vernacular languages; combined with the introduction of the printing press, this would allow many more people access to books, especially the Bible.

In all, the Renaissance could be viewed as an attempt by intellectuals to study and improve the secular and worldly, both through the revival of ideas from antiquity, and through novel approaches to thought. Some scholars, such as Rodney Stark, play down the Renaissance in favour of the earlier innovations of the Italian city-states in the High Middle Ages, which married responsive government, Christianity and the birth of capitalism. This analysis argues that, whereas the great European states (France and Spain) were absolutist monarchies, and others were under direct Church control, the independent city republics of Italy took over the principles of capitalism invented on monastic estates and set off a vast unprecedented commercial revolution that preceded and financed the Renaissance.

Origins

View of Florence, birthplace of the Renaissance

Many argue that the ideas characterizing the Renaissance had their origin in late 13th-century Florence, in particular with the writings of Dante Alighieri (1265–1321) and Petrarch (1304–1374), as well as the paintings of Giotto di Bondone (1267–1337). Some writers date the Renaissance quite precisely; one proposed starting point is 1401, when the rival geniuses Lorenzo Ghiberti and Filippo Brunelleschi competed for the contract to build the bronze doors for the Baptistery of the Florence Cathedral (Ghiberti then won). Others see more general competition between artists and polymaths such as Brunelleschi, Ghiberti, Donatello, and Masaccio for artistic commissions as sparking the creativity of the Renaissance. Yet it remains much debated why the Renaissance began in Italy, and why it began when it did. Accordingly, several theories have been put forward to explain its origins.

During the Renaissance, money and art went hand in hand. Artists depended entirely on patrons while the patrons needed money to foster artistic talent. Wealth was brought to Italy in the 14th, 15th, and 16th centuries by expanding trade into Asia and Europe. Silver mining in Tyrol increased the flow of money. Luxuries from the Muslim world, brought home during the Crusades, increased the prosperity of Genoa and Venice.

Jules Michelet defined the 16th-century Renaissance in France as a period in Europe's cultural history that represented a break from the Middle Ages, creating a modern understanding of humanity and its place in the world.

Latin and Greek phases of Renaissance humanism

In stark contrast to the High Middle Ages, when Latin scholars focused almost entirely on studying Greek and Arabic works of natural science, philosophy and mathematics, Renaissance scholars were most interested in recovering and studying Latin and Greek literary, historical, and oratorical texts. Broadly speaking, this began in the 14th century with a Latin phase, when Renaissance scholars such as Petrarch, Coluccio Salutati (1331–1406), Niccolò de' Niccoli (1364–1437) and Poggio Bracciolini (1380–1459) scoured the libraries of Europe in search of works by such Latin authors as Cicero, Lucretius, Livy and Seneca. By the early 15th century, the bulk of the surviving such Latin literature had been recovered; the Greek phase of Renaissance humanism was under way, as Western European scholars turned to recovering ancient Greek literary, historical, oratorical and theological texts.

Unlike with Latin texts, which had been preserved and studied in Western Europe since late antiquity, the study of ancient Greek texts was very limited in medieval Western Europe. Ancient Greek works on science, maths and philosophy had been studied since the High Middle Ages in Western Europe and in the Islamic Golden Age (normally in translation), but Greek literary, oratorical and historical works (such as Homer, the Greek dramatists, Demosthenes and Thucydides) were not studied in either the Latin or medieval Islamic worlds; in the Middle Ages these sorts of texts were only studied by Byzantine scholars. Some argue that the Timurid Renaissance in Samarkand and Herat, whose magnificence toned with Florence as the center of a cultural rebirth, were linked to the Ottoman Empire, whose conquests led to the migration of Greek scholars to Italian cities. One of the greatest achievements of Renaissance scholars was to bring this entire class of Greek cultural works back into Western Europe for the first time since late antiquity.

Muslim logicians, most notably Avicenna and Averroes, had inherited Greek ideas after they had invaded and conquered Egypt and the Levant. Their translations and commentaries on these ideas worked their way through the Arab West into Iberia and Sicily, which became important centers for this transmission of ideas. From the 11th to the 13th century, many schools dedicated to the translation of philosophical and scientific works from Classical Arabic to Medieval Latin were established in Iberia, most notably the Toledo School of Translators. This work of translation from Islamic culture, though largely unplanned and disorganized, constituted one of the greatest transmissions of ideas in history. The movement to reintegrate the regular study of Greek literary, historical, oratorical and theological texts back into the Western European curriculum is usually dated to the 1396 invitation from Coluccio Salutati to the Byzantine diplomat and scholar Manuel Chrysoloras (c. 1355–1415) to teach Greek in Florence. This legacy was continued by a number of expatriate Greek scholars, from Basilios Bessarion to Leo Allatius.

Social and political structures in Italy

The unique political structures of late Middle Ages Italy have led some to theorize that its unusual social climate allowed the emergence of a rare cultural efflorescence. Italy did not exist as a political entity in the early modern period. Instead, it was divided into smaller city states and territories: the Kingdom of Naples controlled the south, the Republic of Florence and the Papal States at the center, the Milanese and the Genoese to the north and west respectively, and the Venetians to the east. Fifteenth-century Italy was one of the most urbanised areas in Europe. Many of its cities stood among the ruins of ancient Roman buildings; it seems likely that the classical nature of the Renaissance was linked to its origin in the Roman Empire's heartland.

Historian and political philosopher Quentin Skinner points out that Otto of Freising (c. 1114–1158), a German bishop visiting north Italy during the 12th century, noticed a widespread new form of political and social organization, observing that Italy appeared to have exited from Feudalism so that its society was based on merchants and commerce. Linked to this was anti-monarchical thinking, represented in the famous early Renaissance fresco cycle The Allegory of Good and Bad Government by Ambrogio Lorenzetti (painted 1338–1340), whose strong message is about the virtues of fairness, justice, republicanism and good administration. Holding both Church and Empire at bay, these city republics were devoted to notions of liberty. Skinner reports that there were many defences of liberty such as the Matteo Palmieri (1406–1475) celebration of Florentine genius not only in art, sculpture and architecture, but "the remarkable efflorescence of moral, social and political philosophy that occurred in Florence at the same time".

Even cities and states beyond central Italy, such as the Republic of Florence at this time, were also notable for their merchant Republics, especially the Republic of Venice. Although in practice these were oligarchical, and bore little resemblance to a modern democracy, they did have democratic features and were responsive states, with forms of participation in governance and belief in liberty. The relative political freedom they afforded was conducive to academic and artistic advancement. Likewise, the position of Italian cities such as Venice as great trading centres made them intellectual crossroads. Merchants brought with them ideas from far corners of the globe, particularly the Levant. Venice was Europe's gateway to trade with the East, and a producer of fine glass, while Florence was a capital of textiles. The wealth such business brought to Italy meant large public and private artistic projects could be commissioned and individuals had more leisure time for study.

Black Death

Pieter Bruegel's The Triumph of Death (c. 1562) reflects the social upheaval and terror that followed the plague that devastated medieval Europe.

One theory that has been advanced is that the devastation in Florence caused by the Black Death, which hit Europe between 1348 and 1350, resulted in a shift in the world view of people in 14th century Italy. Italy was particularly badly hit by the plague, and it has been speculated that the resulting familiarity with death caused thinkers to dwell more on their lives on Earth, rather than on spirituality and the afterlife. It has also been argued that the Black Death prompted a new wave of piety, manifested in the sponsorship of religious works of art. However, this does not fully explain why the Renaissance occurred specifically in Italy in the 14th century. The Black Death was a pandemic that affected all of Europe in the ways described, not only Italy. The Renaissance's emergence in Italy was most likely the result of the complex interaction of the above factors.

The plague was carried by fleas on sailing vessels returning from the ports of Asia, spreading quickly due to lack of proper sanitation: the population of England, then about 4.2 million, lost 1.4 million people to the bubonic plague. Florence's population was nearly halved in the year 1347. As a result of the decimation in the populace the value of the working class increased, and commoners came to enjoy more freedom. To answer the increased need for labor, workers traveled in search of the most favorable position economically.

The demographic decline due to the plague had economic consequences: the prices of food dropped and land values declined by 30–40% in most parts of Europe between 1350 and 1400. Landholders faced a great loss, but for ordinary men and women it was a windfall. The survivors of the plague found not only that the prices of food were cheaper but also that lands were more abundant, and many of them inherited property from their dead relatives.

The spread of disease was significantly more rampant in areas of poverty. Epidemics ravaged cities, particularly children. Plagues were easily spread by lice, unsanitary drinking water, armies, or by poor sanitation. Children were hit the hardest because many diseases, such as typhus and syphilis, target the immune system, leaving young children without a fighting chance. Children in city dwellings were more affected by the spread of disease than the children of the wealthy.

The Black Death caused greater upheaval to Florence's social and political structure than later epidemics. Despite a significant number of deaths among members of the ruling classes, the government of Florence continued to function during this period. Formal meetings of elected representatives were suspended during the height of the epidemic due to the chaotic conditions in the city, but a small group of officials was appointed to conduct the affairs of the city, which ensured continuity of government.

Cultural conditions in Florence

It has long been a matter of debate why the Renaissance began in Florence, and not elsewhere in Italy. Scholars have noted several features unique to Florentine cultural life that may have caused such a cultural movement. Many have emphasized the role played by the Medici, a banking family and later ducal ruling house, in patronizing and stimulating the arts. Lorenzo de' Medici (1449–1492) was the catalyst for an enormous amount of arts patronage, encouraging his countrymen to commission works from the leading artists of Florence, including Leonardo da Vinci, Sandro Botticelli, and Michelangelo Buonarroti. Works by Neri di Bicci, Botticelli, da Vinci, and Filippino Lippi had been commissioned additionally by the Convent of San Donato in Scopeto in Florence.

The Renaissance was certainly underway before Lorenzo de' Medici came to power – indeed, before the Medici family itself achieved hegemony in Florentine society. Some historians have postulated that Florence was the birthplace of the Renaissance as a result of luck, i.e., because "Great Men" were born there by chance: Leonardo da Vinci, Botticelli and Michelangelo were all born in Tuscany. Arguing that such chance seems improbable, other historians have contended that these "Great Men" were only able to rise to prominence because of the prevailing cultural conditions at the time.

Characteristics

Humanism

In some ways, Renaissance humanism was not a philosophy but a method of learning. In contrast to the medieval scholastic mode, which focused on resolving contradictions between authors, Renaissance humanists would study ancient texts in the original and appraise them through a combination of reasoning and empirical evidence. Humanist education was based on the programme of Studia Humanitatis, the study of five humanities: poetry, grammar, history, moral philosophy, and rhetoric. Although historians have sometimes struggled to define humanism precisely, most have settled on "a middle of the road definition... the movement to recover, interpret, and assimilate the language, literature, learning and values of ancient Greece and Rome". Above all, humanists asserted "the genius of man ... the unique and extraordinary ability of the human mind".

Pico della Mirandola, writer of the famous Oration on the Dignity of Man, which has been called the "Manifesto of the Renaissance".

Humanist scholars shaped the intellectual landscape throughout the early modern period. Political philosophers such as Niccolò Machiavelli and Thomas More revived the ideas of Greek and Roman thinkers and applied them in critiques of contemporary government, following the Islamic steps of Ibn Khaldun. Pico della Mirandola wrote the "manifesto" of the Renaissance, the Oration on the Dignity of Man, a vibrant defence of thinking. Matteo Palmieri (1406–1475), another humanist, is most known for his work Della vita civile ("On Civic Life"; printed 1528), which advocated civic humanism, and for his influence in refining the Tuscan vernacular to the same level as Latin. Palmieri drew on Roman philosophers and theorists, especially Cicero, who, like Palmieri, lived an active public life as a citizen and official, as well as a theorist and philosopher and also Quintilian. Perhaps the most succinct expression of his perspective on humanism is in a 1465 poetic work La città di vita, but an earlier work, Della vita civile, is more wide-ranging. Composed as a series of dialogues set in a country house in the Mugello countryside outside Florence during the plague of 1430, Palmieri expounds on the qualities of the ideal citizen. The dialogues include ideas about how children develop mentally and physically, how citizens can conduct themselves morally, how citizens and states can ensure probity in public life, and an important debate on the difference between that which is pragmatically useful and that which is honest.

The humanists believed that it is important to transcend to the afterlife with a perfect mind and body, which could be attained with education. The purpose of humanism was to create a universal man whose person combined intellectual and physical excellence and who was capable of functioning honorably in virtually any situation. This ideology was referred to as the uomo universale, an ancient Greco-Roman ideal. Education during the Renaissance was mainly composed of ancient literature and history as it was thought that the classics provided moral instruction and an intensive understanding of human behavior.

Humanism and libraries

A unique characteristic of some Renaissance libraries is that they were open to the public. These libraries were places where ideas were exchanged and where scholarship and reading were considered both pleasurable and beneficial to the mind and soul. As freethinking was a hallmark of the age, many libraries contained a wide range of writers. Classical texts could be found alongside humanist writings. These informal associations of intellectuals profoundly influenced Renaissance culture. Some of the richest "bibliophiles" built libraries as temples to books and knowledge. A number of libraries appeared as manifestations of immense wealth joined with a love of books. In some cases, cultivated library builders were also committed to offering others the opportunity to use their collections. Prominent aristocrats and princes of the Church created great libraries for the use of their courts, called "court libraries", and were housed in lavishly designed monumental buildings decorated with ornate woodwork, and the walls adorned with frescoes (Murray, Stuart A.P.)

Art

Renaissance art marks a cultural rebirth at the close of the Middle Ages and rise of the Modern world. One of the distinguishing features of Renaissance art was its development of highly realistic linear perspective. Giotto di Bondone (1267–1337) is credited with first treating a painting as a window into space, but it was not until the demonstrations of architect Filippo Brunelleschi (1377–1446) and the subsequent writings of Leon Battista Alberti (1404–1472) that perspective was formalized as an artistic technique.

Leonardo da Vinci's Vitruvian Man (c. 1490) demonstrates the effect writers of Antiquity had on Renaissance thinkers. Based on the specifications in Vitruvius' De architectura (1st century BC), Leonardo tried to draw the perfectly proportioned man. (Museum Gallerie dell'Accademia, Venice)

The development of perspective was part of a wider trend towards realism in the arts. Painters developed other techniques, studying light, shadow, and, famously in the case of Leonardo da Vinci, human anatomy. Underlying these changes in artistic method was a renewed desire to depict the beauty of nature and to unravel the axioms of aesthetics, with the works of Leonardo, Michelangelo and Raphael representing artistic pinnacles that were much imitated by other artists. Other notable artists include Sandro Botticelli, working for the Medici in Florence, Donatello, another Florentine, and Titian in Venice, among others.

In the Netherlands, a particularly vibrant artistic culture developed. The work of Hugo van der Goes and Jan van Eyck was particularly influential on the development of painting in Italy, both technically with the introduction of oil paint and canvas, and stylistically in terms of naturalism in representation. Later, the work of Pieter Brueghel the Elder would inspire artists to depict themes of everyday life.

In architecture, Filippo Brunelleschi was foremost in studying the remains of ancient classical buildings. With rediscovered knowledge from the 1st-century writer Vitruvius and the flourishing discipline of mathematics, Brunelleschi formulated the Renaissance style that emulated and improved on classical forms. His major feat of engineering was building the dome of the Florence Cathedral. Another building demonstrating this style is the church of St. Andrew in Mantua, built by Alberti. The outstanding architectural work of the High Renaissance was the rebuilding of St. Peter's Basilica, combining the skills of Bramante, Michelangelo, Raphael, Sangallo and Maderno.

During the Renaissance, architects aimed to use columns, pilasters, and entablatures as an integrated system. The Roman orders types of columns are used: Tuscan and Composite. These can either be structural, supporting an arcade or architrave, or purely decorative, set against a wall in the form of pilasters. One of the first buildings to use pilasters as an integrated system was in the Old Sacristy (1421–1440) by Brunelleschi. Arches, semi-circular or (in the Mannerist style) segmental, are often used in arcades, supported on piers or columns with capitals. There may be a section of entablature between the capital and the springing of the arch. Alberti was one of the first to use the arch on a monumental. Renaissance vaults do not have ribs; they are semi-circular or segmental and on a square plan, unlike the Gothic vault, which is frequently rectangular.

Renaissance artists were not pagans, although they admired antiquity and kept some ideas and symbols of the medieval past. Nicola Pisano (c. 1220 – c. 1278) imitated classical forms by portraying scenes from the Bible. His Annunciation, from the Baptistry at Pisa, demonstrates that classical models influenced Italian art before the Renaissance took root as a literary movement

Science

Applied innovation extended to commerce. At the end of the 15th century Luca Pacioli published the first work on bookkeeping, making him the founder of accounting.

The rediscovery of ancient texts and the invention of the printing press in about 1440 democratized learning and allowed a faster propagation of more widely distributed ideas. In the first period of the Italian Renaissance, humanists favoured the study of humanities over natural philosophy or applied mathematics, and their reverence for classical sources further enshrined the Aristotelian and Ptolemaic views of the universe. Writing around 1450, Nicholas Cusanus anticipated the heliocentric worldview of Copernicus, but in a philosophical fashion.

Science and art were intermingled in the early Renaissance, with polymath artists such as Leonardo da Vinci making observational drawings of anatomy and nature. Da Vinci set up controlled experiments in water flow, medical dissection, and systematic study of movement and aerodynamics, and he devised principles of research method that led Fritjof Capra to classify him as the "father of modern science". Other examples of Da Vinci's contribution during this period include machines designed to saw marbles and lift monoliths, and new discoveries in acoustics, botany, geology, anatomy, and mechanics.

A suitable environment had developed to question classical scientific doctrine. The discovery in 1492 of the New World by Christopher Columbus challenged the classical worldview. The works of Ptolemy (in geography) and Galen (in medicine) were found to not always match everyday observations. As the Protestant Reformation and Counter-Reformation clashed, the Northern Renaissance showed a decisive shift in focus from Aristotelean natural philosophy to chemistry and the biological sciences (botany, anatomy, and medicine). The willingness to question previously held truths and search for new answers resulted in a period of major scientific advancements.

Some view this as a "scientific revolution", heralding the beginning of the modern age, others as an acceleration of a continuous process stretching from the ancient world to the present day. Significant scientific advances were made during this time by Galileo Galilei, Tycho Brahe, and Johannes Kepler. Copernicus, in De revolutionibus orbium coelestium (On the Revolutions of the Heavenly Spheres), posited that the Earth moved around the Sun. De humani corporis fabrica (On the Workings of the Human Body) by Andreas Vesalius, gave a new confidence to the role of dissection, observation, and the mechanistic view of anatomy.

Another important development was in the process for discovery, the scientific method, focusing on empirical evidence and the importance of mathematics, while discarding much of Aristotelian science. Early and influential proponents of these ideas included Copernicus, Galileo, and Francis Bacon. The new scientific method led to great contributions in the fields of astronomy, physics, biology, and anatomy.

Navigation and geography

The world map by Pietro Coppo, Venice, 1520

During the Renaissance, extending from 1450 to 1650, every continent was visited and mostly mapped by Europeans, except the south polar continent now known as Antarctica. This development is depicted in the large world map Nova Totius Terrarum Orbis Tabula made by the Dutch cartographer Joan Blaeu in 1648 to commemorate the Peace of Westphalia.

In 1492, Christopher Columbus sailed across the Atlantic Ocean from Spain seeking a direct route to India of the Delhi Sultanate. He accidentally stumbled upon the Americas, but believed he had reached the East Indies.

In 1606, the Dutch navigator Willem Janszoon sailed from the East Indies in the VOC ship Duyfken and landed in Australia. He charted about 300 km of the west coast of Cape York Peninsula in Queensland. More than thirty Dutch expeditions followed, mapping sections of the north, west, and south coasts. In 1642–1643, Abel Tasman circumnavigated the continent, proving that it was not joined to the imagined south polar continent.

By 1650, Dutch cartographers had mapped most of the coastline of the continent, which they named New Holland, except the east coast which was charted in 1770 by Captain Cook.

The long-imagined south polar continent was eventually sighted in 1820. Throughout the Renaissance it had been known as Terra Australis, or 'Australia' for short. However, after that name was transferred to New Holland in the nineteenth century, the new name of 'Antarctica' was bestowed on the south polar continent.

Music

From this changing society emerged a common, unifying musical language, in particular the polyphonic style of the Franco-Flemish school. The development of printing made distribution of music possible on a wide scale. Demand for music as entertainment and as an activity for educated amateurs increased with the emergence of a bourgeois class. Dissemination of chansons, motets, and masses throughout Europe coincided with the unification of polyphonic practice into the fluid style that culminated in the second half of the sixteenth century in the work of composers such as Palestrina, Lassus, Victoria, and William Byrd.

Religion

Alexander VI, a Borgia Pope infamous for his corruption

The new ideals of humanism, although more secular in some aspects, developed against a Christian backdrop, especially in the Northern Renaissance. Much, if not most, of the new art was commissioned by or in dedication to the Church. However, the Renaissance had a profound effect on contemporary theology, particularly in the way people perceived the relationship between man and God. Many of the period's foremost theologians were followers of the humanist method, including Erasmus, Zwingli, Thomas More, Martin Luther, and John Calvin.

The Renaissance began in times of religious turmoil. The late Middle Ages was a period of political intrigue surrounding the Papacy, culminating in the Western Schism, in which three men simultaneously claimed to be true Bishop of Rome. While the schism was resolved by the Council of Constance (1414), a resulting reform movement known as Conciliarism sought to limit the power of the pope. Although the papacy eventually emerged supreme in ecclesiastical matters by the Fifth Council of the Lateran (1511), it was dogged by continued accusations of corruption, most famously in the person of Pope Alexander VI, who was accused variously of simony, nepotism, and fathering four children (most of whom were married off, presumably for the consolidation of power) while a cardinal.

Churchmen such as Erasmus and Luther proposed reform to the Church, often based on humanist textual criticism of the New Testament. In October 1517 Luther published the 95 Theses, challenging papal authority and criticizing its perceived corruption, particularly with regard to instances of sold indulgences. The 95 Theses led to the Reformation, a break with the Roman Catholic Church that previously claimed hegemony in Western Europe. Humanism and the Renaissance therefore played a direct role in sparking the Reformation, as well as in many other contemporaneous religious debates and conflicts.

Pope Paul III came to the papal throne (1534–1549) after the sack of Rome in 1527, with uncertainties prevalent in the Catholic Church following the Protestant Reformation. Nicolaus Copernicus dedicated De revolutionibus orbium coelestium (On the Revolutions of the Celestial Spheres) to Paul III, who became the grandfather of Alessandro Farnese (cardinal), who had paintings by Titian, Michelangelo, and Raphael, as well as an important collection of drawings, and who commissioned the masterpiece of Giulio Clovio, arguably the last major illuminated manuscript, the Farnese Hours.

Self-awareness

By the 15th century, writers, artists, and architects in Italy were well aware of the transformations that were taking place and were using phrases such as modi antichi (in the antique manner) or alle romana et alla antica (in the manner of the Romans and the ancients) to describe their work. In the 1330s Petrarch referred to pre-Christian times as antiqua (ancient) and to the Christian period as nova (new). From Petrarch's Italian perspective, this new period (which included his own time) was an age of national eclipse. Leonardo Bruni was the first to use tripartite periodization in his History of the Florentine People (1442). Bruni's first two periods were based on those of Petrarch, but he added a third period because he believed that Italy was no longer in a state of decline. Flavio Biondo used a similar framework in Decades of History from the Deterioration of the Roman Empire (1439–1453).

Humanist historians argued that contemporary scholarship restored direct links to the classical period, thus bypassing the Medieval period, which they then named for the first time the "Middle Ages". The term first appears in Latin in 1469 as media tempestas (middle times). The term rinascita (rebirth) first appeared, however, in its broad sense in Giorgio Vasari's Lives of the Artists, 1550, revised 1568. Vasari divides the age into three phases: the first phase contains Cimabue, Giotto, and Arnolfo di Cambio; the second phase contains Masaccio, Brunelleschi, and Donatello; the third centers on Leonardo da Vinci and culminates with Michelangelo. It was not just the growing awareness of classical antiquity that drove this development, according to Vasari, but also the growing desire to study and imitate nature.

Spread

In the 15th century, the Renaissance spread rapidly from its birthplace in Florence to the rest of Italy and soon to the rest of Europe. The invention of the printing press by German printer Johannes Gutenberg allowed the rapid transmission of these new ideas. As it spread, its ideas diversified and changed, being adapted to local culture. In the 20th century, scholars began to break the Renaissance into regional and national movements.

"What a piece of work is a man, how noble in reason, how infinite in faculties, in form and moving how express and admirable, in action how like an angel, in apprehension how like a god!" – from William Shakespeare's Hamlet.

In England, the sixteenth century marked the beginning of the English Renaissance with the work of writers William Shakespeare (1564 –1616), Christopher Marlowe (1564 – 1593), Edmund Spenser (1552/1553 – 1599), Sir Thomas More (1478 – 1535), Francis Bacon (1561 – 1626), Sir Philip Sidney (1554 – 1586), architects (such as Inigo Jones (1573 – 1652), who introduced Italianate architecture to England), and composers such as Thomas Tallis (1505 – 1585), John Taverner (c. 1490 – 1545), and William Byrd (c.1539/40 or 1543 – 1623).

France

The word "Renaissance" is borrowed from the French language, where it means "re-birth". It was first used in the eighteenth century and was later popularized by French historian Jules Michelet (1798–1874) in his 1855 work, Histoire de France (History of France).

In 1495 the Italian Renaissance arrived in France, imported by King Charles VIII after his invasion of Italy. A factor that promoted the spread of secularism was the inability of the Church to offer assistance against the Black Death. Francis I imported Italian art and artists, including Leonardo da Vinci, and built ornate palaces at great expense. Writers such as François Rabelais, Pierre de Ronsard, Joachim du Bellay, and Michel de Montaigne, painters such as Jean Clouet, and musicians such as Jean Mouton also borrowed from the spirit of the Renaissance.

In 1533, a fourteen-year-old Caterina de' Medici (1519–1589), born in Florence to Lorenzo de' Medici, Duke of Urbino and Madeleine de la Tour d'Auvergne, married Henry II of France, second son of King Francis I and Queen Claude. Though she became famous and infamous for her role in France's religious wars, she made a direct contribution in bringing arts, sciences, and music (including the origins of ballet) to the French court from her native Florence.

Germany

In the second half of the 15th century, the Renaissance spirit spread to Germany and the Low Countries, where the development of the printing press (ca. 1450) and Renaissance artists such as Albrecht Dürer (1471–1528) predated the influence from Italy. In the early Protestant areas of the country humanism became closely linked to the turmoil of the Protestant Reformation, and the art and writing of the German Renaissance frequently reflected this dispute. However, the Gothic style and medieval scholastic philosophy remained exclusively until the turn of the 16th century. Emperor Maximilian I of Habsburg (ruling 1493–1519) was the first truly Renaissance monarch of the Holy Roman Empire.

Hungary

After Italy, Hungary was the first European country where the Renaissance appeared. The Renaissance style came directly from Italy during the Quattrocento to Hungary first in the Central European region, thanks to the development of early Hungarian-Italian relationships—not only in dynastic connections, but also in cultural, humanistic and commercial relations—growing in strength from the 14th century. The relationship between Hungarian and Italian Gothic styles was a second reason—exaggerated breakthrough of walls is avoided, preferring clean and light structures. Large-scale building schemes provided ample and long term work for the artists, for example, the building of the Friss (New) Castle in Buda, the castles of Visegrád, Tata, and Várpalota. In Sigismund's court there were patrons such as Pipo Spano, a descendant of the Scolari family of Florence, who invited Manetto Ammanatini and Masolino da Pannicale to Hungary.

The new Italian trend combined with existing national traditions to create a particular local Renaissance art. Acceptance of Renaissance art was furthered by the continuous arrival of humanist thought in the country. Many young Hungarians studying at Italian universities came closer to the Florentine humanist center, so a direct connection with Florence evolved. The growing number of Italian traders moving to Hungary, specially to Buda, helped this process. New thoughts were carried by the humanist prelates, among them Vitéz János, archbishop of Esztergom, one of the founders of Hungarian humanism. During the long reign of emperor Sigismund of Luxemburg the Royal Castle of Buda became probably the largest Gothic palace of the late Middle Ages. King Matthias Corvinus (r. 1458–1490) rebuilt the palace in early Renaissance style and further expanded it.

After the marriage in 1476 of King Matthias to Beatrice of Naples, Buda became one of the most important artistic centres of the Renaissance north of the Alps. The most important humanists living in Matthias' court were Antonio Bonfini and the famous Hungarian poet Janus Pannonius. András Hess set up a printing press in Buda in 1472. Matthias Corvinus's library, the Bibliotheca Corviniana, was Europe's greatest collections of secular books: historical chronicles, philosophic and scientific works in the 15th century. His library was second only in size to the Vatican Library. (However, the Vatican Library mainly contained Bibles and religious materials.) In 1489, Bartolomeo della Fonte of Florence wrote that Lorenzo de' Medici founded his own Greek-Latin library encouraged by the example of the Hungarian king. Corvinus's library is part of UNESCO World Heritage.

Matthias started at least two major building projects. The works in Buda and Visegrád began in about 1479. Two new wings and a hanging garden were built at the royal castle of Buda, and the palace at Visegrád was rebuilt in Renaissance style. Matthias appointed the Italian Chimenti Camicia and the Dalmatian Giovanni Dalmata to direct these projects.  Matthias commissioned the leading Italian artists of his age to embellish his palaces: for instance, the sculptor Benedetto da Majano and the painters Filippino Lippi and Andrea Mantegna worked for him. A copy of Mantegna's portrait of Matthias survived. Matthias also hired the Italian military engineer Aristotele Fioravanti to direct the rebuilding of the forts along the southern frontier. He had new monasteries built in Late Gothic style for the Franciscans in Kolozsvár, Szeged and Hunyad, and for the Paulines in Fejéregyháza. In the spring of 1485, Leonardo da Vinci travelled to Hungary on behalf of Sforza to meet king Matthias Corvinus, and was commissioned by him to paint a Madonna.

Matthias enjoyed the company of Humanists and had lively discussions on various topics with them. The fame of his magnanimity encouraged many scholars—mostly Italian—to settle in Buda. Antonio Bonfini, Pietro Ranzano, Bartolomeo Fonzio, and Francesco Bandini spent many years in Matthias's court. This circle of educated men introduced the ideas of Neoplatonism to Hungary. Like all intellectuals of his age, Matthias was convinced that the movements and combinations of the stars and planets exercised influence on individuals' life and on the history of nations. Galeotto Marzio described him as "king and astrologer", and Antonio Bonfini said Matthias "never did anything without consulting the stars". Upon his request, the famous astronomers of the age, Johannes Regiomontanus and Marcin Bylica, set up an observatory in Buda and installed it with astrolabes and celestial globes. Regiomontanus dedicated his book on navigation that was used by Christopher Columbus to Matthias.

Other important figures of Hungarian Renaissance include Bálint Balassi (poet), Sebestyén Tinódi Lantos (poet), Bálint Bakfark (composer and lutenist), and Master MS (fresco painter).

Renaissance in the Low countries

Culture in the Netherlands at the end of the 15th century was influenced by the Italian Renaissance through trade via Bruges, which made Flanders wealthy. Its nobles commissioned artists who became known across Europe. In science, the anatomist Andreas Vesalius led the way; in cartography, Gerardus Mercator's map assisted explorers and navigators. In art, Dutch and Flemish Renaissance painting ranged from the strange work of Hieronymus Bosch to the everyday life depictions of Pieter Brueghel the Elder.

Northern Europe

The Renaissance in Northern Europe has been termed the "Northern Renaissance". While Renaissance ideas were moving north from Italy, there was a simultaneous southward spread of some areas of innovation, particularly in music. The music of the 15th-century Burgundian School defined the beginning of the Renaissance in music, and the polyphony of the Netherlanders, as it moved with the musicians themselves into Italy, formed the core of the first true international style in music since the standardization of Gregorian Chant in the 9th century. The culmination of the Netherlandish school was in the music of the Italian composer Palestrina. At the end of the 16th century Italy again became a center of musical innovation, with the development of the polychoral style of the Venetian School, which spread northward into Germany around 1600.

The paintings of the Italian Renaissance differed from those of the Northern Renaissance. Italian Renaissance artists were among the first to paint secular scenes, breaking away from the purely religious art of medieval painters. Northern Renaissance artists initially remained focused on religious subjects, such as the contemporary religious upheaval portrayed by Albrecht Dürer. Later, the works of Pieter Bruegel influenced artists to paint scenes of daily life rather than religious or classical themes. It was also during the Northern Renaissance that Flemish brothers Hubert and Jan van Eyck perfected the oil painting technique, which enabled artists to produce strong colors on a hard surface that could survive for centuries. A feature of the Northern Renaissance was its use of the vernacular in place of Latin or Greek, which allowed greater freedom of expression. This movement had started in Italy with the decisive influence of Dante Alighieri on the development of vernacular languages; in fact the focus on writing in Italian has neglected a major source of Florentine ideas expressed in Latin. The spread of the printing press technology boosted the Renaissance in Northern Europe as elsewhere, with Venice becoming a world center of printing.

Poland

An early Italian humanist who came to Poland in the mid-15th century was Filippo Buonaccorsi. Many Italian artists came to Poland with Bona Sforza of Milan, when she married King Sigismund I the Old in 1518. This was supported by temporarily strengthened monarchies in both areas, as well as by newly established universities. The Polish Renaissance lasted from the late 15th to the late 16th century and was the Golden Age of Polish culture. Ruled by the Jagiellon dynasty, the Kingdom of Poland (from 1569 known as the Polish–Lithuanian Commonwealth) actively participated in the broad European Renaissance. The multi-national Polish state experienced a substantial period of cultural growth thanks in part to a century without major wars – aside from conflicts in the sparsely populated eastern and southern borderlands. The Reformation spread peacefully throughout the country (giving rise to the Polish Brethren), while living conditions improved, cities grew, and exports of agricultural products enriched the population, especially the nobility (szlachta) who gained dominance in the new political system of Golden Liberty. The Polish Renaissance architecture has three periods of development.

The greatest monument of this style in the territory of the former Duchy of Pomerania is the Ducal Castle in Szczecin.

Portugal

Although Italian Renaissance had a modest impact in Portuguese arts, Portugal was influential in broadening the European worldview, stimulating humanist inquiry. Renaissance arrived through the influence of wealthy Italian and Flemish merchants who invested in the profitable commerce overseas. As the pioneer headquarters of European exploration, Lisbon flourished in the late 15th century, attracting experts who made several breakthroughs in mathematics, astronomy and naval technology, including Pedro Nunes, João de Castro, Abraham Zacuto and Martin Behaim. Cartographers Pedro Reinel, Lopo Homem, Estêvão Gomes and Diogo Ribeiro made crucial advances in mapping the world. Apothecary Tomé Pires and physicians Garcia de Orta and Cristóvão da Costa collected and published works on plants and medicines, soon translated by Flemish pioneer botanist Carolus Clusius.

In architecture, the huge profits of the spice trade financed a sumptuous composite style in the first decades of the 16th century, the Manueline, incorporating maritime elements. The primary painters were Nuno Gonçalves, Gregório Lopes and Vasco Fernandes. In music, Pedro de Escobar and Duarte Lobo produced four songbooks, including the Cancioneiro de Elvas. In literature, Sá de Miranda introduced Italian forms of verse. Bernardim Ribeiro developed pastoral romance, plays by Gil Vicente fused it with popular culture, reporting the changing times, and Luís de Camões inscribed the Portuguese feats overseas in the epic poem Os Lusíadas. Travel literature especially flourished: João de Barros, Castanheda, António Galvão, Gaspar Correia, Duarte Barbosa, and Fernão Mendes Pinto, among others, described new lands and were translated and spread with the new printing press. After joining the Portuguese exploration of Brazil in 1500, Amerigo Vespucci coined the term New World, in his letters to Lorenzo di Pierfrancesco de' Medici.

The intense international exchange produced several cosmopolitan humanist scholars, including Francisco de Holanda, André de Resende and Damião de Góis, a friend of Erasmus who wrote with rare independence on the reign of King Manuel I. Diogo and André de Gouveia made relevant teaching reforms via France. Foreign news and products in the Portuguese factory in Antwerp attracted the interest of Thomas More and Albrecht Dürer to the wider world. There, profits and know-how helped nurture the Dutch Renaissance and Golden Age, especially after the arrival of the wealthy cultured Jewish community expelled from Portugal.

Russia

There was no Renaissance in Russia in the original sense.

Renaissance trends from Italy and Central Europe influenced Russia in many ways. Their influence was rather limited, however, due to the large distances between Russia and the main European cultural centers and the strong adherence of Russians to their Orthodox traditions and Byzantine legacy.

Prince Ivan III introduced Renaissance architecture to Russia by inviting a number of architects from Italy, who brought new construction techniques and some Renaissance style elements with them, while in general following the traditional designs of Russian architecture. In 1475 the Bolognese architect Aristotele Fioravanti came to rebuild the Cathedral of the Dormition in the Moscow Kremlin, which had been damaged in an earthquake. Fioravanti was given the 12th-century Vladimir Cathedral as a model, and he produced a design combining traditional Russian style with a Renaissance sense of spaciousness, proportion and symmetry.

In 1485 Ivan III commissioned the building of the royal residence, Terem Palace, within the Kremlin, with Aloisio da Milano as the architect of the first three floors. He and other Italian architects also contributed to the construction of the Kremlin walls and towers. The small banquet hall of the Russian Tsars, called the Palace of Facets because of its facetted upper story, is the work of two Italians, Marco Ruffo and Pietro Solario, and shows a more Italian style. In 1505, an Italian known in Russia as Aleviz Novyi or Aleviz Fryazin arrived in Moscow. He may have been the Venetian sculptor, Alevisio Lamberti da Montagne. He built twelve churches for Ivan III, including the Cathedral of the Archangel, a building remarkable for the successful blending of Russian tradition, Orthodox requirements and Renaissance style. It is believed that the Cathedral of the Metropolitan Peter in Vysokopetrovsky Monastery, another work of Aleviz Novyi, later served as an inspiration for the so-called octagon-on-tetragon architectural form in the Moscow Baroque of the late 17th century.

Between the early 16th and the late 17th centuries, an original tradition of stone tented roof architecture developed in Russia. It was quite unique and different from the contemporary Renaissance architecture elsewhere in Europe, though some research terms the style 'Russian Gothic' and compares it with the European Gothic architecture of the earlier period. The Italians, with their advanced technology, may have influenced the invention of the stone tented roof (the wooden tents were known in Russia and Europe long before). According to one hypothesis, an Italian architect called Petrok Maly may have been an author of the Ascension Church in Kolomenskoye, one of the earliest and most prominent tented roof churches.

By the 17th century the influence of Renaissance painting resulted in Russian icons becoming slightly more realistic, while still following most of the old icon painting canons, as seen in the works of Bogdan Saltanov, Simon Ushakov, Gury Nikitin, Karp Zolotaryov, and other Russian artists of the era. Gradually the new type of secular portrait painting appeared, called parsúna (from "persona" – person), which was transitional style between abstract iconographics and real paintings.

In the mid 16th-century Russians adopted printing from Central Europe, with Ivan Fyodorov being the first known Russian printer. In the 17th century printing became widespread, and woodcuts became especially popular. That led to the development of a special form of folk art known as lubok printing, which persisted in Russia well into the 19th century.

A number of technologies from the European Renaissance period were adopted by Russia rather early and subsequently perfected to become a part of a strong domestic tradition. Mostly these were military technologies, such as cannon casting adopted by at least the 15th century. The Tsar Cannon, which is the world's largest bombard by caliber, is a masterpiece of Russian cannon making. It was cast in 1586 by Andrey Chokhov and is notable for its rich, decorative relief. Another technology, that according to one hypothesis originally was brought from Europe by the Italians, resulted in the development of vodka, the national beverage of Russia. As early as 1386 Genoese ambassadors brought the first aqua vitae ("water of life") to Moscow and presented it to Grand Duke Dmitry Donskoy. The Genoese likely developed this beverage with the help of the alchemists of Provence, who used an Arab-invented distillation apparatus to convert grape must into alcohol. A Moscovite monk called Isidore used this technology to produce the first original Russian vodka c. 1430.

Spain

The Renaissance arrived in the Iberian peninsula through the Mediterranean possessions of the Aragonese Crown and the city of Valencia. Many early Spanish Renaissance writers come from the Kingdom of Aragon, including Ausiàs March and Joanot Martorell. In the Kingdom of Castile, the early Renaissance was heavily influenced by the Italian humanism, starting with writers and poets such as the Marquis of Santillana, who introduced the new Italian poetry to Spain in the early 15th century. Other writers, such as Jorge Manrique, Fernando de Rojas, Juan del Encina, Juan Boscán Almogáver, and Garcilaso de la Vega, kept a close resemblance to the Italian canon. Miguel de Cervantes's masterpiece Don Quixote is credited as the first Western novel. Renaissance humanism flourished in the early 16th century, with influential writers such as philosopher Juan Luis Vives, grammarian Antonio de Nebrija and natural historian Pedro de Mexía.

Later Spanish Renaissance tended towards religious themes and mysticism, with poets such as fray Luis de León, Teresa of Ávila, and John of the Cross, and treated issues related to the exploration of the New World, with chroniclers and writers such as Inca Garcilaso de la Vega and Bartolomé de las Casas, giving rise to a body of work, now known as Spanish Renaissance literature. The late Renaissance in Spain produced artists such as El Greco and composers such as Tomás Luis de Victoria and Antonio de Cabezón.

Historiography

Conception

A cover of the Lives of the Artists by Giorgio Vasari

The Italian artist and critic Giorgio Vasari (1511–1574) first used the term rinascita in his book The Lives of the Artists (published 1550). In the book Vasari attempted to define what he described as a break with the barbarities of Gothic art: the arts (he held) had fallen into decay with the collapse of the Roman Empire and only the Tuscan artists, beginning with Cimabue (1240–1301) and Giotto (1267–1337) began to reverse this decline in the arts. Vasari saw ancient art as central to the rebirth of Italian art.

However, only in the 19th century did the French word renaissance achieve popularity in describing the self-conscious cultural movement based on revival of Roman models that began in the late 13th century. French historian Jules Michelet (1798–1874) defined "The Renaissance" in his 1855 work Histoire de France as an entire historical period, whereas previously it had been used in a more limited sense. For Michelet, the Renaissance was more a development in science than in art and culture. He asserted that it spanned the period from Columbus to Copernicus to Galileo; that is, from the end of the 15th century to the middle of the 17th century. Moreover, Michelet distinguished between what he called, "the bizarre and monstrous" quality of the Middle Ages and the democratic values that he, as a vocal Republican, chose to see in its character. A French nationalist, Michelet also sought to claim the Renaissance as a French movement.

The Swiss historian Jacob Burckhardt (1818–1897) in his The Civilization of the Renaissance in Italy (1860), by contrast, defined the Renaissance as the period between Giotto and Michelangelo in Italy, that is, the 14th to mid-16th centuries. He saw in the Renaissance the emergence of the modern spirit of individuality, which the Middle Ages had stifled. His book was widely read and became influential in the development of the modern interpretation of the Italian Renaissance. However, Buckhardt has been accused of setting forth a linear Whiggish view of history in seeing the Renaissance as the origin of the modern world.

More recently, some historians have been much less keen to define the Renaissance as a historical age, or even as a coherent cultural movement. The historian Randolph Starn, of the University of California Berkeley, stated in 1998:

Rather than a period with definitive beginnings and endings and consistent content in between, the Renaissance can be (and occasionally has been) seen as a movement of practices and ideas to which specific groups and identifiable persons variously responded in different times and places. It would be in this sense a network of diverse, sometimes converging, sometimes conflicting cultures, not a single, time-bound culture.

Debates about progress

There is debate about the extent to which the Renaissance improved on the culture of the Middle Ages. Both Michelet and Burckhardt were keen to describe the progress made in the Renaissance towards the modern age. Burckhardt likened the change to a veil being removed from man's eyes, allowing him to see clearly.

In the Middle Ages both sides of human consciousness – that which was turned within as that which was turned without – lay dreaming or half awake beneath a common veil. The veil was woven of faith, illusion, and childish prepossession, through which the world and history were seen clad in strange hues.

— Jacob Burckhardt, The Civilization of the Renaissance in Italy

On the other hand, many historians now point out that most of the negative social factors popularly associated with the medieval period—poverty, warfare, religious and political persecution, for example—seem to have worsened in this era, which saw the rise of Machiavellian politics, the Wars of Religion, the corrupt Borgia Popes, and the intensified witch hunts of the 16th century. Many people who lived during the Renaissance did not view it as the "golden age" imagined by certain 19th-century authors, but were concerned by these social maladies. Significantly, though, the artists, writers, and patrons involved in the cultural movements in question believed they were living in a new era that was a clean break from the Middle Ages. Some Marxist historians prefer to describe the Renaissance in material terms, holding the view that the changes in art, literature, and philosophy were part of a general economic trend from feudalism towards capitalism, resulting in a bourgeois class with leisure time to devote to the arts.

Johan Huizinga (1872–1945) acknowledged the existence of the Renaissance but questioned whether it was a positive change. In his book The Autumn of the Middle Ages, he argued that the Renaissance was a period of decline from the High Middle Ages, destroying much that was important. The Latin language, for instance, had evolved greatly from the classical period and was still a living language used in the church and elsewhere. The Renaissance obsession with classical purity halted its further evolution and saw Latin revert to its classical form. Robert S. Lopez has contended that it was a period of deep economic recession. Meanwhile, George Sarton and Lynn Thorndike have both argued that scientific progress was perhaps less original than has traditionally been supposed. Finally, Joan Kelly argued that the Renaissance led to greater gender dichotomy, lessening the agency women had had during the Middle Ages.

Some historians have begun to consider the word Renaissance to be unnecessarily loaded, implying an unambiguously positive rebirth from the supposedly more primitive "Dark Ages", the Middle Ages. Most historians now prefer to use the term "early modern" for this period, a more neutral designation that highlights the period as a transitional one between the Middle Ages and the modern era. Others such as Roger Osborne have come to consider the Italian Renaissance as a repository of the myths and ideals of western history in general, and instead of rebirth of ancient ideas as a period of great innovation.

The art historian Erwin Panofsky observed of this resistance to the concept of "Renaissance":

It is perhaps no accident that the factuality of the Italian Renaissance has been most vigorously questioned by those who are not obliged to take a professional interest in the aesthetic aspects of civilization – historians of economic and social developments, political and religious situations, and, most particularly, natural science – but only exceptionally by students of literature and hardly ever by historians of Art.

Other Renaissances

The term Renaissance has also been used to define periods outside of the 15th and 16th centuries. Charles H. Haskins (1870–1937), for example, made a case for a Renaissance of the 12th century. Other historians have argued for a Carolingian Renaissance in the 8th and 9th centuries, Ottonian Renaissance in the 10th century and for the Timurid Renaissance of the 14th century. The Islamic Golden Age has been also sometimes termed with the Islamic Renaissance.

Other periods of cultural rebirth have also been termed "renaissances", such as the Bengal Renaissance, Tamil Renaissance, Nepal Bhasa renaissance, al-Nahda or the Harlem Renaissance. The term can also be used in cinema. In animation, the Disney Renaissance is a period that spanned the years from 1989 to 1999 which saw the studio return to the level of quality not witnessed since their Golden Age or Animation. The San Francisco Renaissance was a vibrant period of exploratory poetry and fiction writing in that city in the mid-20th century.

Commonsense knowledge (artificial intelligence)

From Wikipedia, the free encyclopedia
https://en.wikipedia.org/wiki/Commonsense_knowledge_(artificial_intelligence)

In artificial intelligence research, commonsense knowledge consists of facts about the everyday world, such as "Lemons are sour", that all humans are expected to know. It is currently an unsolved problem in Artificial General Intelligence and is a focus of the Allen Institute for Artificial Intelligence. The first AI program to address common sense knowledge was Advice Taker in 1959 by John McCarthy.

Commonsense knowledge can underpin a commonsense reasoning process, to attempt inferences such as "You might bake a cake because you want people to eat the cake." A natural language processing process can be attached to the commonsense knowledge base to allow the knowledge base to attempt to answer questions about the world. Common sense knowledge also helps to solve problems in the face of incomplete information. Using widely held beliefs about everyday objects, or common sense knowledge, AI systems make common sense assumptions or default assumptions about the unknown similar to the way people do. In an AI system or in English, this is expressed as "Normally P holds", "Usually P" or "Typically P so Assume P". For example, if we know the fact "Tweety is a bird", because we know the commonly held belief about birds, "typically birds fly," without knowing anything else about Tweety, we may reasonably assume the fact that "Tweety can fly." As more knowledge of the world is discovered or learned over time, the AI system can revise its assumptions about Tweety using a truth maintenance process. If we later learn that "Tweety is a penguin" then truth maintenance revises this assumption because we also know "penguins do not fly".

Commonsense reasoning

Commonsense reasoning simulates the human ability to use commonsense knowledge to make presumptions about the type and essence of ordinary situations they encounter every day, and to change their "minds" should new information come to light. This includes time, missing or incomplete information and cause and effect. The ability to explain cause and effect is an important aspect of explainable AI. Truth maintenance algorithms automatically provide an explanation facility because they create elaborate records of presumptions. Compared with humans, all existing computer programs that attempt human-level AI perform extremely poorly on modern "commonsense reasoning" benchmark tests such as the Winograd Schema Challenge. The problem of attaining human-level competency at "commonsense knowledge" tasks is considered to probably be "AI complete" (that is, solving it would require the ability to synthesize a fully human-level intelligence), although some oppose this notion and believe compassionate intelligence is also required for human-level AI. Common sense reasoning has been applied successfully in more limited domains such as natural language processing and automated diagnosis or analysis.

Applications

Around 2013, MIT researchers developed BullySpace, an extension of the commonsense knowledgebase ConceptNet, to catch taunting social media comments. BullySpace included over 200 semantic assertions based around stereotypes, to help the system infer that comments like "Put on a wig and lipstick and be who you really are" are more likely to be an insult if directed at a boy than a girl.

ConceptNet has also been used by chatbots and by computers that compose original fiction. At Lawrence Livermore National Laboratory, common sense knowledge was used in an intelligent software agent to detect violations of a comprehensive nuclear test ban treaty.

Data

As an example, as of 2012 ConceptNet includes these 21 language-independent relations:

  • IsA
  • UsedFor
  • HasA
  • CapableOf
  • Desires
  • CreatedBy ("cake" can be created by "baking")
  • PartOf

  • AtLocation (Somewhere a "cook" can be at a "restaurant")
  • DefinedAs
  • SymbolOf (X represents Y)
  • ReceivesAction ("cake" can be "eaten")
  • HasPrerequisite (X can't do Y unless A does B)
  • MotivatedByGoal (You would "bake" because you want to "eat")
  • CausesDesire ("baking" makes you want to "follow recipe")
