In 1424 the "duo preciso e noto" ("well and known duo") of Masaccio and Masolino was commissioned by the powerful and rich Felice Brancacci to execute a cycle of frescoes for the Brancacci Chapel in the church of Santa Maria del Carmine in Florence. Painting began around 1425 with the two artists probably working simultaneously. For reasons that are unclear they left the chapel unfinished, and it was completed by Filippino Lippi in the 1480s. The iconography of the fresco decoration is somewhat unusual; while the majority of the frescoes represent the life of St. Peter, 2 scenes, on either side of the threshold of the chapel space, depict the temptation and expulsion of Adam and Eve. As a whole the frescoes represent human sin and its redemption through the actions of Peter, the first pope.[8] The style of Masaccio's scenes shows the influence of Giotto especially. Figures are large, heavy, and solid; emotions are expressed through faces and gestures; and there is a strong impression of naturalism throughout the paintings. Unlike Giotto, however, Masaccio uses linear and atmospheric perspective, directional light, and chiaroscuro, which is the representation of form through light and color without outlines. As a result his frescoes are even more convincingly lifelike than those of his trecento predecessor.
