Peter Paul Rubens – The Triumph of Rome: The Youthful Emperor Constantine Honouring Rome Mauritshuis

The picture has something of this: baroque, saint, Renaissance, sculpture, museum, cavalry, man, ancient, marble, people, interior, monument, fountain, nude, sword.
Perhaps it’s a painting of a group of people standing in front of a stage with a man on one side of the stage and a woman on the other.
