Portrait of William Cavendish, 1st Duke of Devonshire Sir Godfrey Kneller (1646-1723)

The picture has something of this: sword, armor, people, knight, woman, weapon, portrait, man, warrior, Renaissance, wear, veil, cape, sash.
Perhaps it’s a painting of a man in a black and white outfit with a bow in his hand and a sword in his other hand.
