Van der Meulen, Adam-Frans – Arrivée de Louis XIV devant Douai, 2 juillet 1667 Château de Versailles

The picture has something of this: people, tree, group, landscape, many, water, river, vehicle, cavalry, transportation system, beach, crowd, city.
Perhaps it’s a painting of a large group of people in a field with horses and a man on the other side of the painting with a sky in the background.
