Agostino dei Musi was born and trained as an engraver in Venice. He adopted 'Veneziano' as his name after he moved to Rome about 1515, where he joined the workshop of Marcantonio Raimondi. He remained in the city until the Sack of Rome in 1527.
This is a reverse copy of the engraving by Raimondi, itself reproducing a drawing by Titian (today in the Uffizi). Raimondi initially trained and worked in Bologna. He spent time in Venice in 1506, before settling in Rome. His engraving, c1505-1515, is in the same direction as the Titian drawing. It is completely unsigned and Bartsch, and others after him till more recently, mistakenly assumed it was after Raphael. Both Titian and Raimondi did not give St Jerome a halo, which Veneziano added. Raimondi had added the small rock beneath the tree, which might have been intended for his monogram, but he left blank.
