Duccio di Buoninsegna (Italian: [ËduttÊo di ËbwÉninËseÉ²É²a]; c. 1255â1260 â c. 1318â1319) was an Italian painter active in Siena, Tuscany, in the late 13th and early 14th centuries. He was hired throughout his life to complete many important works in government and religious buildings around Italy. Duccio is credited with creating the painting styles of Trecento and the Sienese school, and also contributed significantly to the Sienese Gothic style.
