Ballerinas in the restroom Zinaida Serebryakova (1884-1967)

The picture has something of this: people, group, sculpture, veil, ancient, man, god, nude, woman, wear, Renaissance, saint, baroque, shirtless, museum.
Perhaps it’s a painting of a group of ballerinas with a man on one side of a horse and a woman on the other side of the other.
