The fresco of the Last Supper in the convent of Sant'Apollonia, completed in 1447, reflects the genius of Renaissance art. This large work, nearly 15 feet high and 32 feet wide, showcases linear perspective. The artist's humor is evident in details like St. Bartholomew's reaction to St. Andrew's knife.
