Perino's examples are: "Abraham and Isaac", "Jacob wrestling with the Angel", "Joseph and his Brothers", the "Hebrews crossing the Jordan", "Fall and Capture of Jericho", "Joshua commanding Sun to stand still", "Birth of Christ", "Baptism and the Last Supper". Some of these are in bronze-tint, while others are in full color. He also painted, after Raphael's drawings, figures of the planets in the great hall of the Appartamenti Borgia. Perino was soon regarded as his major assistant, second only to Giulio Romano.
