Castor and Polux Delivering Helen Amable-Paul Coutan (1792-1837)

The picture has something of this: people, woman, group, man, wear, two, ballet dancer, veil, dancing, dancer, theater, nude, portrait, dress, royalty, costume.
Perhaps it’s a painting of two men and a woman standing in front of a man laying on a bed next to a woman with a hat on her head.
