Gallery sets sights on Donne portrait

London’s National Portrait Gallery announced Friday that it is trying to raise $2.94 million to purchase a portrait of 16th century British poet John Donne.

The gallery will have six months to raise the money for the portrait, which belongs to an unidentified family and is currently on loan for an exhibition of Shakespearean art starting in March.

The portrait, which is thought to date to 1595, was lost for centuries after it was bequeathed by Donne to a British earl. It was discovered in a collection of paintings by Sotheby’s in 1959 after being “mislabeled.”
