Sienese School
Stefano di Giovanni di Consolo, known as il Sassetta (ca.1392–1450 or 1451) was an Tuscan painter of the Renaissance, and a significant figure of the Sienese School. While working within the Sienese tradition, he innovated the style by introducing elements derived from the decorative Gothic style and the realism of contemporary Florentine innovators as Masaccio.
