Aelbert Cuyp – Horsemen and Herdsmen with Cattle National Gallery of Art (Washington)

The picture has something of this: people, tree, group, landscape, mammal, cavalry, man, daylight, seated, outdoors, recreation, vehicle, dawn, silhouette, military, wear, skirmish, backlit.
Perhaps it’s a painting of a group of people riding horses and a man on a horse in the foreground with a castle in the distance in the background.
