Jacques Courtois – Battle of Arbelles, 331 BCE Château de Versailles

The picture has something of this: people, group, many, cavalry, man, skirmish, war, seated, soldier, transportation system, weapon, woman, veil, battlefield, herder.
Perhaps it’s a painting of a large group of men and women on horses in a field with a mountain in the back ground and clouds in the sky in the background.
