The Sienese school of painting flourished in Siena, Italy, between the thirteenth and fifteenth centuries, developing alongside - and often in contrast to - the more naturalistic Florentine school. Its founding master, Duccio, fused Byzantine formality with new grace and sweetness; his pupil Simone Martini carried the style to the papal court at Avignon, while the brothers Pietro and Ambrogio Lorenzetti pushed it toward dramatic narrative and observed space. Later masters include Domenico and Taddeo di Bartolo, Sassetta, and Matteo di Giovanni. Sienese painting is decorative and lyrical where Florentine is sculptural and austere: gold grounds, tooled ornament, flowing Gothic line, and rich color make its altarpieces read like precious objects. The Black Death of 1348, which killed both Lorenzetti brothers, checked the school's momentum, but its elegance fed directly into International Gothic.
