The portrait has been dated variously from c. 1511 to the early 1520s. The style of the sitter's clothing and hair suggest a date closer to 1513; certainly before 1520. According to Gronau, "It has in style its companion in the Parma at Vienna, and must have been painted about 1511. It shows the period of transition from the purely Giorgionesque style to Titian's quite personal one."
