Certosa di Pavia
Zenale was born in Treviglio, Lombardy, where in 1485 he finished the great polyptych for the church of St. Martin, together with his fellow Bernardino Butinone. Like Butinone, he is said to have trained with Vincenzo Civerchio. Later he collaborated to the decoration of the Certosa di Pavia. Subsequently, he was engaged by Ludovico Sforza, Duke of Milan, to paint a room in the Castello Sforzesco of that city. Also with Butinone, he frescoed the Grifi Chapel in the church of San Pietro in Gessate.
