The old attribution is to Vasari (1511-1574). The style and figure types however seem wholly typical of the drawings of the Genoese painter and designer of engravings, Bernardo Castello. Similar figure types occur in other drawings by the master, for example The Assault on Jerusalem in the École des Beaux Arts, París (inv. no. 97 [11974)].
