Studio of Marcus Gheeraerts, the Younger – Robert Devereux, 2nd Earl of Essex National Gallery of Art (Washington)

The picture has something of this: people, portrait, man, royalty, sculpture, wear, veil, ancient, crown, Renaissance, god, facial hair, saint, sword.
Perhaps it’s a close up of a painting of a man with a beard wearing a white suit and a black cape and holding a gold object in his right hand.
