correct. For summaries, assess the requested topic; do not require a summary to
repeat every transcript detail. References guide scope but are not exhaustive.
Different wording or extra relevant detail is not a factual error. Distinguish
an essential missing answer item from an optional coverage preference.

The source_context contains source spans with stable IDs. Joining their text
fields reconstructs the complete original source exactly. Cite source_span_ids;
the program extracts verbatim quotes itself. Never invent an ID or cite an
unrelated span. For every factual error, unsupported claim or required omission,
identify the specific issue, give a concise claim description, quote the exact
relevant answer phrase (empty only for a required omission), and cite the source
span IDs establishing the issue. Read surrounding source before deciding:
absence in one span does not prove absence in the whole document. Source IDs
establish traceability, not automatic truth or entailment.
Use source_ambiguity when context allows multiple readings; do not turn an
ambiguous label or unsupported inference about the source into a confident error.
Use coverage_concern for optional missing detail; that alone is not a material
failure. Explain required omissions relative to the question, not a preferred
summary style. Preserve dates, before/after relations, attribution and entities.

Verdicts: correct (answers the task with no material error), partially_correct
(correct core but a material error/required omission), incorrect (central answer
wrong), uncertain (evidence or interpretation insufficient). A negative verdict
requires a concrete material issue and exact source support; otherwise uncertain.
Give a rationale and source span IDs supporting a correct answer. Do not

Bubonic plague is caused by the bacterium Yersinia pestis spread by fleas, but during the Black Death it probably also took a secondary form, spread by person-to-person contact via aerosols, causing pneumonic plague.The Black Death was the beginning of the second plague pandemic. The plague created religious, social and economic upheavals, with profound effects on the course of European history.\n"}, {"span_id": "s00014", "text": "The origin of the Black Death is disputed. Genetic analysis points to the evolution of Yersinia pestis in the Tian Shan mountains on the border between Kyrgyzstan and China 2,600 years ago. The immediate territorial origins of the Black Death and its outbreak remains unclear with some pointing towards Central Asia, China, the Middle East and Europe. The pandemic was reportedly first introduced to Europe during the siege of the Genoese trading port of Kaffa in Crimea by the Golden Horde army of Jani Beg in 1347. From Crimea, it was most likely carried by fleas living on the black rats that travelled on Genoese ships, spreading through the Mediterranean Basin and reaching North Africa, Western Asia and the rest of Europe via Constantinople, Sicily and the Italian Peninsula. There is evidence that once it came ashore, the Black Death mainly spread person-to-person as pneumonic plague, thus explaining the quick inland spread of the epidemic, which was faster than would be expected if the primary vector was rat fleas causing bubonic plague. In 2022, it was discovered that there was a sudden surge of deaths in what is today Kyrgyzstan from the Black Death in the late 1330s; when combined with genetic evidence, this implies that the initial spread may not have been due to Mongol conquests in the 14th century, as previously speculated.The Black Death was the second great natural disaster to strike Europe during the Late Middle Ages (the first one being the Great Famine of 1315–1317) and is estimated to have killed 30 percent to 60 percent of the European population, as well as about one-third of the population of the Middle East. The plague might have reduced the world population from c. 475 million to 350–375 million in the 14th century. There were further outbreaks throughout the Late Middle Ages and, with other contributing factors (the Crisis of the Late Middle Ages), the European population did not regain its level in 1300 until 1500.

In English prior to the 18th century, the event was called the \"pestilence\" or \"great pestilence\", \"the plague\" or the \"great death\". Subsequent to the pandemic \"the furste moreyn\" (first murrain) or \"first pestilence\" was applied, to distinguish the mid-14th century phenomenon from other infectious diseases and epidemics of plague.The 1347 pandemic plague was not referred to specifically as \"black\" in the time of occurrence in any European language, though the expression \"black death\" had occasionally been applied to fatal disease beforehand. \"Black death\" was not used to describe the plague pandemic in English until the 1750s; the term is first attested in 1755, where it translated Danish: den sorte død, lit. 'the black death'. This expression as a proper name for the pandemic had been popularized by Swedish and Danish chroniclers in the 15th and early 16th centuries, and in the 16th and 17th centuries was transferred to other languages as a calque: Icelandic: svarti dauði, German: der schwarze Tod, and French: la mort noire. Previously, most European languages had named the pandemic a variant or calque of the Latin: magna mortalitas, lit. 'Great Death'.The phrase 'black death' – describing Death as black – is very old. Homer used it in the Odyssey to describe the monstrous Scylla, with her mouths \"full of black Death\" (Ancient Greek: πλεῖοι μέλανος Θανάτοιο, romanized: pleîoi mélanos Thanátoio). Seneca the Younger may have been the first to describe an epidemic as 'black death', (Latin: mors atra) but only in reference to the acute lethality and dark prognosis of disease. The 12th–13th century French physician Gilles de Corbeil had already used atra mors to refer to a \"pestilential fever\" (febris pestilentialis) in his work On the Signs and Symptoms of Diseases (De signis et symptomatibus aegritudium). The phrase mors nigra, 'black death', was used in 1350 by Simon de Covino (or Couvin), a Belgian astronomer, in his poem \"On the Judgement of the Sun at a Feast of Saturn\" (De judicio Solis in convivio Saturni), which attributes the plague to an astrological conjunction of Jupiter and Saturn. His use of the phrase is not connected unambiguously with the plague pandemic of 1347 and appears to refer to the fatal outcome of disease.The historian Cardinal Francis Aidan Gasquet wrote about the Great Pestilence in 1893 and suggested that it had been \"some form of the ordinary Eastern or bubonic plague\". In 1908, Gasquet said use of the name atra mors for the 14th-century epidemic first appeared in a 1631 book on Danish history by J. I. Pontanus: \"Commonly and from its effects, they called it the black death\" (Vulgo & ab effectu atram mortem vocitabant).\n"}, {"span_id": "s00018", "text": "\n"}, {"span_id": "s00019", "text": "Previous plague epidemics\n"}, {"span_id": "s00020", "text": "Research from 2017 suggests plague first infected humans in Europe and Asia in the Late Neolithic-Early Bronze Age.

This Y. pestis may have been different from more modern types, with bubonic plague transmissible by fleas first known from Bronze Age remains near Samara.The symptoms of bubonic plague are first attested in a fragment of Rufus of Ephesus preserved by Oribasius; these ancient medical authorities suggest bubonic plague had appeared in the Roman Empire before the reign of Trajan, six centuries before arriving at Pelusium in the reign of Justinian I. In 2013, researchers confirmed earlier speculation that the cause of the Plague of Justinian (541–542 CE, with recurrences until 750) was Y. pestis. This is known as the first plague pandemic.

The mechanism by which Y. pestis is usually transmitted was established in 1898 by Paul-Louis Simond and was found to involve the bites of fleas whose midguts had become obstructed by replicating Y. pestis several days after feeding on an infected host. This blockage starves the fleas and drives them to aggressive feeding behaviour and attempts to clear the blockage by regurgitation, resulting in thousands of plague bacteria being flushed into the feeding site, infecting the host. The bubonic plague mechanism was also dependent on two populations of rodents: one resistant to the disease, which act as hosts, keeping the disease endemic, and a second that lacks resistance. When the second population dies, the fleas move on to other hosts, including people, thus creating a human epidemic.\n"}, {"span_id": "s00029", "text": "\n"}, {"span_id": "s00030", "text": "DNA evidence\n"}, {"span_id": "s00031", "text": "Definitive confirmation of the role of Y. pestis arrived in 2010 with a publication in PLOS Pathogens by Haensch et al.

The authors concluded that this new research, together with prior analyses from the south of France and Germany, \"ends the debate about the cause of the Black Death, and unambiguously demonstrates that Y. pestis was the causative agent of the epidemic plague that devastated Europe during the Middle Ages\". In 2011, these results were further confirmed with genetic evidence derived from Black Death victims in the East Smithfield burial site in England. Schuenemann et al. concluded in 2011 \"that the Black Death in medieval Europe was caused by a variant of Y. pestis that may no longer exist\".Later in 2011, Bos et al. reported in Nature the first draft genome of Y. pestis from plague victims from the same East Smithfield cemetery and indicated that the strain that caused the Black Death is ancestral to most modern strains of Y. pestis.Since this time, further genomic papers have further confirmed the phylogenetic placement of the Y. pestis strain responsible for the Black Death as both the ancestor of later plague epidemics including the third plague pandemic and as the descendant of the strain responsible for the Plague of Justinian. In addition, plague genomes from significantly earlier in prehistory have been recovered.DNA taken from 25 skeletons from 14th century London have shown plague is a strain of Y. pestis almost identical to that which hit Madagascar in 2013.

The second model claims to better fit the trends of death toll because the rat-flea-human hypothesis would have produced a delayed but very high spike in deaths, which contradict historical death data.Lars Walløe complains that all of these authors \"take it for granted that Simond's infection model, black rat → rat flea → human, which was developed to explain the spread of plague in India, is the only way an epidemic of Yersinia pestis infection could spread\", whilst pointing to several other possibilities. Similarly, Monica Green has argued that greater attention is needed to the range of (especially non-commensal) animals that might be involved in the transmission of plague.Archaeologist Barney Sloane has argued that there is insufficient evidence of the extinction of numerous rats in the archaeological record of the medieval waterfront in London and that the disease spread too quickly to support the thesis that Y. pestis was spread from fleas on rats; he argues that transmission must have been person to person.

In 2014, Public Health England announced the results of an examination of 25 bodies exhumed in the Clerkenwell area of London, as well as of wills registered in London during the period, which supported the pneumonic hypothesis.

The earliest Chinese descriptions of the bubonic plague do not appear until the 1640s.Nestorian graves dating to 1338–1339 near Issyk-Kul in Kyrgyzstan have inscriptions referring to plague, which has led some historians and epidemiologists to think they mark the outbreak of the epidemic; this is supported by recent direct findings of Y. pestis DNA in teeth samples from graves in the area with inscriptions referring to \"pestilence\" as the cause of death.

There are no records of the symptoms of the Black Death from Mongol sources or writings from travelers east of the Black Sea prior to the Crimean outbreak in 1346. Finally, the Silk Road had already been heavily disrupted before the spread of the Black Death.

As the disease took hold, Genoese traders fled across the Black Sea to Constantinople, where the disease first arrived in Europe in summer 1347.The epidemic there killed the 13-year-old son of the Byzantine emperor, John VI Kantakouzenos, who wrote a description of the disease modelled on Thucydides's account of the 5th century BCE Plague of Athens, but noting the spread of the Black Death by ship between maritime cities.

A study published in 2022 of pollen samples across Europe between 1250 and 1450 was used to estimate changes in agricultural output before and after the Black Death. The authors found great variability in different regions, with evidence for high mortality in areas of Scandinavia, France, western Germany, Greece and central Italy, but uninterrupted agricultural growth in central and eastern Europe, Iberia and Ireland.The mortality rate of the Black Death in the 14th century was far greater than the worst 20th-century outbreaks of Y. pestis plague, which occurred in India and killed as much as 3% of the population of certain cities. The overwhelming number of deceased bodies produced by the Black Death caused the necessity of mass burial sites in Europe, sometimes including up to several hundred or several thousand skeletons. The mass burial sites that have been excavated have allowed archaeologists to continue interpreting and defining the biological, sociological, historical and anthropological implications of the Black Death.According to medieval historian Philip Daileader, it is likely that over four years, 45–50% of the European population died of plague. Norwegian historian Ole Benedictow suggests it could have been as much as 60% of the European population. In 1348, the disease spread so rapidly that before any physicians or government authorities had time to reflect upon its origins, about a third of the European population had already perished. In crowded cities, it was not uncommon for as much as 50% of the population to die. Half of Paris' population of 100,000 people died. In Italy, the population of Florence was reduced from between 110,000 and 120,000 inhabitants in 1338 down to 50,000 in 1351. At least 60% of the population of Hamburg and Bremen perished, and a similar percentage of Londoners may have died from the disease as well, with a death toll of approximately 62,000 between 1346 and 1353. Florence's tax records suggest that 80% of the city's population died within four months in 1348. Before 1350, there were about 170,000 settlements in Germany, and this was reduced by nearly 40,000 by 1450. The disease bypassed some areas, with the most isolated areas being less vulnerable to contagion. Plague did not appear in Douai in Flanders until the turn of the 15th century, and the impact was less severe on the populations of Hainaut, Finland, northern Germany and areas of Poland.

In the first outbreak, two thirds of the population contracted the illness and most patients died; in the next, half the population became ill but only some died; by the third, a tenth were affected and many survived; while by the fourth occurrence, only one in twenty people were sickened and most of them survived. By the 1380s in Europe, it predominantly affected children. Chalmel de Vinario recognised that bloodletting was ineffective (though he continued to prescribe bleeding for members of the Roman Curia, whom he disliked), and said that all true cases of plague were caused by astrological factors and were incurable; he himself was never able to effect a cure.The most widely accepted estimate for the Middle East, including Iraq, Iran and Syria, during this time, is for a death toll of about a third of the population. The Black Death killed about 40% of Egypt's population. In Cairo, with a population numbering as many as 600,000, and possibly the largest city west of China, between one third and 40% of the inhabitants died within eight months.Italian chronicler Agnolo di Tura recorded his experience from Siena, where plague arrived in May 1348:\n"}, {"span_id": "s00076", "text": "\n"}, {"span_id": "s00077", "text": "Father abandoned child, wife husband, one brother another; for this illness seemed to strike through the breath and sight.

Italy was particularly badly hit by the pandemic, 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.This does not fully explain why the Renaissance occurred 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, in combination with an influx of Greek scholars following the fall of the Byzantine Empire. As a result of the drastic reduction in the populace the value of the working class increased, and commoners came to enjoy more freedom. To answer the increased need for labour, workers travelled in search of the most favorable position economically.Prior to the emergence of the Black Death, the workings of Europe were run by the Catholic Church and the continent was considered a feudalistic society, composed of fiefs and city-states. The pandemic completely restructured both religion and political forces; survivors began to turn to other forms of spirituality and the power dynamics of the fiefs and city-states crumbled.Cairo's population, partly owing to the numerous plague epidemics, was in the early 18th century half of what it was in 1347. The populations of some Italian cities, notably Florence, did not regain their pre-14th century size until the 19th century. The demographic decline due to the pandemic 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 pandemic found not only that the prices of food were lower but also that lands were more abundant, and many of them inherited property from their dead relatives, and this probably destabilised feudalism.The word \"quarantine\" has its roots in this period, though the concept of isolating people to prevent the spread of disease is older. In the city-state of Ragusa (modern Dubrovnik, Croatia), a thirty-day isolation period was implemented in 1377 for new arrivals to the city from plague-affected areas. The isolation period was later extended to forty days, and given the name \"quarantino\" from the Italian word for \"forty\".\n"}, {"span_id": "s00091", "text": "\n"}, {"span_id": "s00092", "text": "Recurrences\n"}, {"span_id": "s00093", "text": "Second plague pandemic\n"}, {"span_id": "s00094", "text": "The plague repeatedly returned to haunt Europe and the Mediterranean throughout the 14th to 17th centuries.

The second pandemic was particularly widespread in the following years: 1360–63; 1374; 1400; 1438–39; 1456–57; 1464–66; 1481–85; 1500–03; 1518–31; 1544–48; 1563–66; 1573–88; 1596–99; 1602–11; 1623–40; 1644–54; and 1664–67. Subsequent outbreaks, though severe, marked the retreat from most of Europe (18th century) and northern Africa (19th century). The historian George Sussman argued that the plague had not occurred in East Africa until the 1900s. However, other sources suggest that the Second pandemic did indeed reach Sub-Saharan Africa.According to historian Geoffrey Parker, \"France alone lost almost a million people to the plague in the epidemic of 1628–31.\" In the first half of the 17th century, a plague killed some 1.7 million people in Italy. More than 1.25 million deaths resulted from the extreme incidence of plague in 17th-century Spain.The Black Death ravaged much of the Islamic world. Plague could be found in the Islamic world almost every year between 1500 and 1850. Sometimes the outbreaks affected small areas, while other outbreaks affected multiple regions. Plague repeatedly struck the cities of North Africa. Algiers lost 30,000–50,000 inhabitants to it in 1620–21, and again in 1654–57, 1665, 1691 and 1740–42. Cairo suffered more than fifty plague epidemics within 150 years from the plague's first appearance, with the final outbreak of the second pandemic there in the 1840s. Plague remained a major event in Ottoman society until the second quarter of the 19th century. Between 1701 and 1750, thirty-seven larger and smaller epidemics were recorded in Constantinople, and an additional thirty-one between 1751 and 1800.

Symptoms of the Bubonic Plague included painful and enlarged or swollen lymph nodes, headaches, chills, fatigue, vomiting, and fevers, and within 3 to 5 days, 80% of the victims would be dead. Historians estimate that it reduced the total world population from 475 million to between 350 and 375 million. In most parts of Europe, it took nearly 80 years for population sizes to recover, and in some areas, it took more than 150 years.From the perspective of many of the survivors, the effect of the plague may have been ultimately favourable, as the massive reduction of the workforce meant their labor was suddenly in higher demand.

Contemporary chronicler Jean Froissart estimated the toll to be one-third, which modern scholars consider less an accurate assessment than an allusion to the Book of Revelation meant to suggest the scope of the plague. Deaths were not evenly distributed across Europe, and some areas were affected very little, but others were all but entirely depopulated.The Black Death hit the culture of towns and cities disproportionately hard although rural areas, where most of the population lived at the time, were also significantly affected. Larger cities were the worst off, as population densities and close living quarters made disease transmission easier. Cities were also strikingly filthy, infested with lice, fleas, and rats, and subject to diseases caused by malnutrition and poor hygiene. The population of the city of Florence was reduced from 110,000 to 120,000 inhabitants in 1338 to 50,000 in 1351. In the cities of Hamburg and Bremen, 60–70% of the inhabitants died. In Provence, Dauphiné, and Normandy, historians observe a decrease of 60% of fiscal hearths. In some regions, two thirds of the population was annihilated. In the town of Givry, in the Bourgogne region of France, the local friar, who used to note 28–29 funerals a year, recorded 649 deaths in 1348, half of them in September. About half the population of Perpignan died over the course of several months (only two of the eight physicians survived the plague). Over 60% of Norway's population died between 1348 and 1350.

Some historians have assumed that the presence of resistant blood groups in the local population helped them resist infection, but the regions were touched by the second plague outbreak in 1360–1363 (the \"little mortality\") and later during the numerous resurgences of the plague (in 1366–1369, 1374–75, 1400, 1407 etc.).

Mortality was particularly high in rural areas, including significant areas of Gaza and Syria. Many rural people fled, leaving their fields and crops, and entire rural provinces are recorded as being totally depopulated. Surviving records in some cities reveal a devastating number of deaths. The 1348 outbreak in Gaza left an estimated 10,000 people dead, and Aleppo recorded a death rate of 500 per day during the same year. In Damascus, at the disease's peak in September and October 1348, a thousand deaths were recorded every day, with overall mortality estimated at between 25 and 38 percent.

Giovanni Boccaccio, an Italian writer and poet of the era, questioned whether it was sent by God for their correction, or if it came through the influence of the heavenly bodies. Christians accused Jews of poisoning public water supplies and alleged that Jews were making an effort to ruin European civilization. The spreading of those rumours led to the complete destruction of entire Jewish towns. In February 1349, 2,000 Jews were murdered in Strasbourg. In August that year, the Jewish communities of Mainz and Cologne were murdered.Where government authorities were concerned, most monarchs instituted measures that prohibited exports of foodstuffs, condemned black market speculators, set price controls on grain and outlawed large-scale fishing. At best, those proved mostly unenforceable; at worst, they contributed to a continental downward spiral. The hardest-hit lands, like England, were unable to buy grain abroad from France because of the prohibition and from most of the rest of the grain producers because of crop failures from shortage of labour. Any grain that could be shipped was eventually taken by pirates or looters to be sold on the black market. Meanwhile, many of the largest countries, most notably England and Scotland, had been at war, used up much of their treasury which exacerbated inflation. In 1337, on the eve of the first wave of the Black Death, England and France went to war in what would become known as the Hundred Years' War.

The levelling effect was reversed by a \"demographic recovery that resulted in renewed population pressure\".

In 1357, a third of property in London was unused because of a severe outbreak in 1348–49.

Since the plague left vast areas of farmland untended, they were made available for pasture and put more meat on the market. The consumption of meat and dairy products went up, as did the export of beef and butter from the Low Countries, Scandinavia and northern Germany. However, the upper class often attempted to stop the changes, initially in Western Europe and more forcefully and successfully in Eastern Europe, by instituting sumptuary laws. They regulated what people (particularly of the peasant class) could wear so that nobles could ensure that peasants did not begin to dress and act as a higher-class member with their increased wealth. Another tactic was to fix prices and wages so that peasants could not demand more with increasing value. In England, the Statute of Labourers 1351 was enforced, which stated that no peasant could ask for more wages than in 1346. That was met with varying success depending on the amount of rebellion it inspired. Such a law was one of the causes of the 1381 Peasants' Revolt in England.\n"}, {"span_id": "s00150", "text": "The rapid development of the use was probably one of the consequences of the Black Death during which many landowning nobles died and left their realty to their widows and minor orphans.\n"}, {"span_id": "s00151", "text": "\n"}, {"span_id": "s00152", "text": "Urban workers\n"}, {"span_id": "s00153", "text": "In the wake of the drastic population decline brought on by the plague, wages shot up, and labourers could move to new localities in response to wage offers. Local and royal authorities in Western Europe instituted wage controls. The government controls sought to freeze wages at the old levels before the Black Death. Within England, for example, the Ordinance of Labourers, enacted in 1349, and the Statute of Labourers, enacted in 1351, restricted both wage increases and the relocation of workers. If workers attempted to leave their current post, employers were given the right to have them imprisoned. The statute was poorly enforced in most areas, and farm wages in England on average doubled between 1350 and 1450, but they were then static until the late 19th century.Cohn, comparing numerous countries, argues that the laws were not designed primarily to freeze wages. Instead, he says that the energetic local and royal measures to control labour and artisans' prices were responses to elite fears of the greed and the possible new powers of the lesser classes that had gained new freedom. Cohn continues that the laws reflected the anxiety that followed the Black Death's new horrors of mass mortality and destruction and from elite anxiety about manifestations, such as the flagellant movement and the persecution of Jews, Catalans (in Sicily) and beggars.\n"}, {"span_id": "s00154", "text": "\n"}, {"span_id": "s00155", "text": "Labour-saving adaptations\n"}, {"span_id": "s00156", "text": "The Black Death encouraged innovation of labour-saving technologies, leading to higher productivity.

Indigenous flora and fauna were replaced by domestic grasses and animals, and domestic woodlands were lost. With depopulation, the process was reversed.

The manorial system was already in trouble, but the Black Death assured its demise throughout much of Western and Central Europe by 1500. Severe depopulation and migration of the village to cities caused an acute shortage of agricultural labourers. Many villages were abandoned. In England, more than 1300 villages were deserted between 1350 and 1500. Wages of labourers were high, but the rise in nominal wages after the Black Death was swamped by inflation and so real wages fell.Labour was in such a short supply that landlords were forced to give better terms of tenure. That resulted in much lower rents in Western Europe. By 1500, a new form of tenure called copyhold became prevalent in Europe. In copyhold, both a landlord and peasant made their best business deal, whereby the peasant got use of the land and the landlord got a fixed annual payment, and both possessed a copy of the tenure agreement. Serfdom did not end everywhere and lingered in parts of Western Europe and was introduced to Eastern Europe only after the Black Death.There was also a change in inheritance law. Before the plague, only sons, especially the eldest son, inherited the ancestral property.

The way that individuals studied the human body notably changed and became a process that dealt more directly with the human body in varied states of sickness and health. Furthermore, the importance of surgeons became more evident.A theory put forth by Stephen O'Brien is that the Black Death is likely responsible by natural selection for the high frequency of the CCR5-Δ32 genetic defect in people of European descent. The gene affects T cell function and provides protection against HIV, smallpox and possibly plague, but for the last, no explanation exists on how it would do that.

The basic Gothic style was revamped with elaborate decoration in the late medieval period. Sculptors in Italian city-states emulated the work of their Roman forefathers, and sculptors in Northern Europe, no doubt inspired by the devastation they had witnessed, gave way to a heightened expression of emotion and an emphasis on individual differences. A tough realism came forth in architecture as in literature. Images of intense sorrow, decaying corpses and individuals with faults as well as virtues emerged. North of the Alps, painting reached a pinnacle of precise realism with Early Dutch painting by artists such as Jan van Eyck (c. 1390 – 1441).
