He ran an important workshop despite his being one of the most uninspired and pedestrian of the better-known painters of the day, and gifted particularly in irrelevant and trivial details. Part of the contract for the 1481 fresco (fresco = the art of painting on fresh, moist plaster with pigments dissolved in water) cycle in the Sistine Chapel in the Vatican was with him, and he appears to have been given a large share of the work. Among his pupils were Piero di Cosimo and Fra Bartolommeo.
There are works by him in Baltimore (Walters), Berlin, Birmingham (Barber Inst.), Boston (Mus.), Cambridge, Florence (Accad., Uffizi, Mus. di S.Marco, churches), Liverpool (Walker), Lucca (Cath.), New York (Met. Mus.), Oxford, Paris (Louvre), Philadelphia (Johnson) and San Marino Cal. (Huntington).
