Attributed to Antoine-Jean Gros – Allegorical Figure of The Republic Château de Versailles

The picture has something of this: woman, wear, people, veil, man, god, saint, dress, sash, seat, sword, portrait, nude, fashionable.
Perhaps it’s a painting of a man dressed in roman garb and holding a sword and a shield, with a red hat on his head and a sword in his left hand.
