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 Niccolo Piccinino, the General of Filippo
Maria Visconti, on June 29, 1440.
