Jean-Baptiste Martin the elder – View of the Chateau-Neuf at Saint-Germain-en-Laye, near the terraces Château de Versailles

The picture has something of this: people, cavalry, outdoors, landscape, tree, group, man, water, seated, woman, sky, recreation.
Perhaps it’s a painting of a palace with a lot of people on horses in the foreground and a man on a horse on the far side of the picture.
