Masaccio, a Florentine painter, whose real name was Tommaso Guidi, born at San Giovanni, near Florence, early in the 15th century, died in 1443. He is said to have been a pupil of Masolino da Panicale, and from his personal habits was called Tommasaccio (shortened to Masaccio), " slovenly Thomas." While a young man he visited Rome, and painted there in the chapel of Santa Caterina in the church of San Clemente a series of frescoes from the life of St. Catharine, and other subjects, which are the earliest works ascribed to him with any certainty. In 1434 he returned to Florence. His frescoes illustrating the life of St. Peter, in the Brancacci chapel of the Carmelite church, introduced a marked improvement in painting. The subjects were the "Expulsion of Adam and Eve from Paradise," the "Tribute Money," "Peter raising a Youth to Life," "Peter and John healing the Cripple," "Peter and John distributing Alms," and "Peter baptizing Converts," in which the figure of a young man who has thrown off his garment and is shivering with sudden cold is celebrated in the history of art.
