Masaccio, The Expulsion of Adam and Eve from Paradise. Wall painting, 208x88 cm. ca. 1425. Brancacci Chapel, Santa Maria del Carmine, Florence. The difficulty of matching the color hues between giornate done on different days –clearly visible in the blue background around Adam and Eve–, made it advisable that joints between tasks conform to the outlines of figures. Roman wall paintings do not reveal such color changes around pontate joints, which therefore remain independent of the composition, further indicating that the murals were not executed with a fresco technique.
