Andrea del Castagno was born at Castagno, a village near Monte Falterona, not far from Florence. During the war between Florence and Milan, he lived in Corella, returning to his home after its end. In 1440 he moved to Florence under the protection of Bernadetto de' Medici. Here he painted the portraits of the citizens hanged after the Battle of Anghiari on the facade of the Palazzo del Podestà, gaining the nickname of Andrea degli Impiccati.
