A photograph of a drawing in the Uffizi, Florence (inv.no.1222 E), attributed to the school of Raphael. The drawing is squared up in black chalk, perhaps for transfer, and may be the modello for the fresco Moses and the burning bush painted by the workshop of Raphael (c.1517-19) in the vault of the eighth bay of the Raphael Loggia in the Vatican, though this drawing contains only a very cursory landscape background.

Dacos (see Bibliographic References) has attributed this drawing, and the execution of the fresco itself, to Guillaume de Marcillat, who designed and painted stained-glass windows for Raphael's Stanze, also in the Vatican.
