In the following May he was commissioned by the Signoria to decorate one of the walls of the Council Hall of the Palazzo Vecchio. The subject he selected was the "Battle of Anghiari." Although he completed the cartoon, the only part of the composition which he eventually executed in colour was an incident in the foreground which dealt with the "Battle of the Standard." One of the many supposed copies of a study of this mural painting now hangs on the south-east staircase in the Victoria and Albert Museum. It depicts the Florentines under Cardinal Ludovico Mezzarota Scarampo fighting against the Milanese under NiccolÒ Piccinino, the General of Filippo Maria Visconti, on June 29, 1440.
