Masaccio (Tommaso Guidi; 1401–28), Florentine painter of the Renaissance, one of the great innovators of Western art. Possibly a pupil of Masolino, Masaccio produced paintings that inspired such painters as Michelangelo and Raphael. Through austere composition and inspired use of light Masaccio created expressive monumental paintings and frescoes, notably in the Brancacci Chapel of Santa Maria del Carmine in Florence. Other works include the Trinity fresco in Santa Maria Novella and the Virgin with St. Anne in the Uffizi Palace, both in Florence.
