Leonardo da Vinci's Lost Masterpiece

Leonardo da Vinci's Lost Masterpiece: The Battle of Anghiari. Had it been completed, it would have been by far the largest and greatest work that Leonardo ever made. All that remains today of this legendary work of art is a collection of small preparatory sketches and paintings that copied the incomplete mural. While the painting itself is generally thought to be lost, some believe that it may still lie concealed behind a counter wall in the Palazzo Vecchio.
