He painted in tempera only, despite the increasing popularity of oil painting during his lifetime, and on panels, though some of his paintings have been transferred to canvas. His predilection for decoratively punched gilded backgrounds is one of the marks of this conservative taste, in part imposed by his patrons. Of his early polyptychs, only one, the altarpiece from Ascoli Piceno, dated 1473, survives in its entirety in its original frame, and still in its original location (the city's Cathedral). All the others have been disassembled and their panels and predella scenes are divided among several museums.
