Nuremberg was one of the largest cities in the Holy Roman Empire in the 1490s, with a population of between 45,000 and 50,000. Thirty-five patrician families composed the City Council. The Council controlled all aspects of printing and craft activities, including the size of each profession and the quality, quantity and type of goods produced. Although dominated by a conservative aristocracy, Nuremberg was a center of northern humanism. Anton Koberger, printer of the "Nuremberg Chronicle", printed the first humanist book in Nuremberg in 1472. Sebald Shreyer, one of the patrons of the chronicle, commissioned paintings from classical mythology for the grand salon of his house. Hartmann Schedel, author of the chronicle, was an avid collector of both Italian Renaissance and German humanist works. Hieronymus Münzer, who assisted Schedel in writing the chronicle's chapter on geography, was among this group, as were Albrecht Dürer and Johann and Willibald Pirckheimer.
