What is "duccio"

Duccio di Buoninsegna (; c. 1255–1260 – c. 1318–1319) was an Italian painter, active in the city of Siena in Tuscany, where he was born, in the late 13th and early 14th centuries.

He is considered to be the father of Sienese painting and, along with a few others, the founder of Western art. 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 style of Trecento and the Sienese school, and contributed significantly to the Sienese Gothic style.
