LEONARDO da Vinci
(b. 1452, Vinci, d. 1519, Cloux, near Amboise)
Fresco and tempera
Sala delle Asse, Castello Sforzesco, Milan
All that remains of Leonardo's decorations in the Castello Sforzesco in Milan are some fragments in the Sala delle Asse which were, when discovered towards the end of the 19th century, restored in such a way that it is scarcely possible anymore to make out their original appearance.
