 It was traditionally identified with a painting that Vasari states Titian painted after returning from Ferrara for his stepfather Giovanni di Castel Bolognese at Faenza, dated to 1515.Critics have also dated it slightly earlier, due to the three sleeping putti to the right, evidently modelled on the "Tondo of the innocents" by Romanino (Musei civici di Padova), which dates to 1513.Several copies of it are known, one of the best of which is that at Rome's Doria Pamphilj Gallery.
