abstract:The Sienese School of painting flourished in Siena, Italy between the 13th and 15th centuries and for a time rivaled Florence, though it was more conservative, being inclined towards the decorative beauty and elegant grace of late Gothic art. Its most important representatives include Duccio, whose work shows Byzantine influence; his pupil Simone Martini; Pietro and Ambrogio Lorenzetti; Domenico and Taddeo di Bartolo; Sassetta and Matteo di Giovanni.
