Medici Cycle: Triumph at Juliers, September 1, 1610 Peter Paul Rubens (1577-1640)

The picture has something of this: saint, Renaissance, baroque, allegory, cavalry, god, people, nude, book, mythology, nymph, holy, man, interior, sword.
Perhaps it’s a painting of a man riding on the back of a white horse next to a woman in a red dress and a man on.
