Portrait of Anne-François d’Harcourt, Duke of Beuvron, as a Character of the Comédie Italienne Jean Honore Fragonard (1732-1806)

The picture has something of this: people, wear, woman, portrait, baroque, saint, Renaissance, wig, veil, crown, man, god, cape, dress, fame.
Perhaps it’s a painting of a man sitting in a chair wearing a white shirt and a white collared shirt with a white ruffle on his left arm.
