This panel served as a model for Leonardo's lost fresco "The Battle of Anghiari". The fresco was to be in the Palazzo Vecchio, town hall for Florence. The subject was a battle fought, and won, ny Florence against their rival Milan. The full scale cartoon was completed and painting was started, but once more Leonardo used an experimental technique, and once more, the fresco was ruined. However another factor in the incompletion of this piece was that fact that Leonardo was forced into working in the same room as his artistic rival Michelangelo.
