Masaccio (Italian: [maˈzattʃo]; December 21, 1401 – summer 1428), born Tommaso di Ser Giovanni di Simone, was the first great Italian painter of the Quattrocento period of the Italian Renaissance. According to Vasari, Masaccio was the best painter of his generation because of his skill at recreating lifelike figures and movements as well as a convincing sense of three-dimensionality. Masaccio died at twenty-six and little is known about the exact circumstances of his death.
