Duccio di Buoninsegna

Although Duccio was the leading Sienese master of his time, little is known about his life. The earliest record of the artist dates from 1278. In 1285 he received the commission for a painting believed to be the Rucellai Madonna now in the Uffizi. His greatest work, however, is the Maestà, a large altarpiece first mentioned in a document of 1308 and finished by June 9, 1311, when it was carried triumphantly through the city streets to the Duomo of Siena.
