Adam Frans van der Meulen – Siege of Valenciennes, 16 March 1677 Château de Versailles

The picture has something of this: cavalry, group, mammal, people, seated, herder, many, landscape, transportation system, skirmish, desert, dust, man, camel.
Perhaps it’s a painting of a large group of people on horses in a field with buildings in the background and smoke billowing out of the sky in the distance.
