Attributed to Claude Deruet – Allegory of the Treaty of the Peace of the Pyrenees Château de Versailles

The picture has something of this: group, people, many, veil, cavalry, reclining, mammal, man, woman, wear, sculpture, temple, god.
Perhaps it’s a painting of a group of people riding on the backs of horses next to a body of water and a sky with a plane in the background.
