Andrea Mantegna who trained in Padua, and then settled in Mantua, was the most influential figure in Italian engraving of the century, although it is still debated whether he actually engraved any plates himself (a debate revived in recent years by Suzanne Boorsch). A number of engravings have long been ascribed to his school or workshop, with only seven usually given to him personally. The whole group form a coherent stylistic group and very clearly reflect his style in painting and drawing, or copy surviving works of his. They seem to date from the late 1460s onwards.
