Muller, Jacques – Ruitergevecht tussen Turkse troepen en troepen van de Oostenrijkse keizer, 1645-1673 Rijksmuseum: part 2

The picture has something of this: group, people, cavalry, many, skirmish, war, man, battle, weapon, recreation, military, action, force, veil.
Perhaps it’s a painting of a man riding on the back of a white horse next to a bunch of other people on a rocky hillside with a mountain in the background.
