Francesco del Cossa (c. 1436 Ferrara-c. 1477 Bologna) is one of the primary representatives of the Ferrarese School of painting, along with Cosme Tura and Ercole de' Roberti; together with the latter, he also founded the School of Bologna. Del Cossa came from an aristocratic family, and is documented as having worked as an artist in his native city from 1546. After a dispute with the Duke of Ferrara over payment for executing allegorical pictures the months of the year, Cossa left and moved to Bologna in 1470. Piero della Francesca, Andrea Mantegna and the sculptor Donatello (1386-1466) were the main influences on Cossa, whose works include The Griffoni altarpiece (center panel), 1473, The National Gallery, London; and Allegory of Autumn, 1475, Gemaldegalerie, SMPK, Berlin.
