Gill Coe Antiques & Interiors has dated this piece to the 19th Century.
She is featured in Michelangelo's frescoes in the Sistine Chapel and in Raphael's frescoes in Santa Maria della Pace. The original oil painting by Zampieri is mentioned in the inventory from 1641 and the list of 1697, and it assigns the work to Domenichino. The frame on this watercolour is not the original one. It has a leather back with an easel stand. A very decorative painting.
