Portrait of Mary (d.1725) Daughter of the 1st Marquis of Powis, as Diana (oil on...

The sitter is shown as Diana, the chaste huntress goddess of the earth and the sky, identified by the crescent moon in her hair. Her right hand rests on a greyhound’s collar decorated with the arms of Herbert under a viscountess’s coronet. She was the daughter of the 1st Marquess, and titular Duke, of Powis and Lady Elizabeth Somerset. The portrait was painted in France soon after she accompanied her father into exile in 1688. Her brother, William, the 2nd Marquess/Duke, was the father of Lady Theresa Herbert, the first wife of Sir Robert Throckmorton, 4th Bt., through whom this picture came to Coughton. She was buried in the Church of the English Augustinian Nuns at Bruges. The landscape is almost certainly a later modification of an architectural background, with a decorative curtain.
