Angelo di Pietro del Macagnino da Siena, Italian painter, son of Pietro da Siena. He was court painter to Borso d'Este, Duke of Ferrara, and, with Cosmè Tura, decorated the Duke's studiolo at the Villa Belfiore (destroyed) from 1447. The iconographic programme was provided by Guarino da Verona. In 1449 Cyriac of Ancona saw two finished paintings of Clio and Melpomene (both untraced) in Angelo's workshop, probably destined for the studiolo. It appears that while in Ferrara, Angelo learned the technique of painting in oils from Rogier van der Weyden, who had been invited to the city in 1449 to paint a triptych with the Deposition, Adam and Eve, and Supplicant Regulus. No work by Angelo has been identified with certainty. //
