Italian painter, leading figure in 15th-century Lombard art, and an artist of exceptional integrity and power.

His earliest dated work is a dramatic painting of the “Three Crosses” (1456). He spent the middle of his life in Pavia in the service of the dukes of Milan, and until the arrival of Leonardo da Vinci he was the most influential painter in the Lombard region. From 1480 he became receptive to the Renaissance style, influenced by Donato Bramante, Andrea Mantegna, and Leonardo da Vinci. This influence appears in the modeling and perspective of his best-known fresco, “The Martyrdom of St. Sebastian” (1485).
