Taddeo di Bartolo

Taddeo di Bartolo (b Siena, c.1362; d Siena, c.1422).
Sienese painter. He was the leading painter in Siena in the first two decades of the 15th century and also worked in and for other cities. His style was conservative, but his frescos of Roman heroes (1413–14) in the Palazzo Pubblico in Siena are forward-looking in subject—early examples of the type of famous men cycle that became popular in the Renaissance.
