Willem de Heusch – Mountainous River Landscape in Italy Mauritshuis

The picture has something of this: cavalry, seated, landscape, tree, mammal, people, farm, herder, outdoors, dawn, sunset, sky, recreation, horse, grass, nature, fall, road, dust.
Perhaps it’s a painting of a group of people riding horses on a dirt road next to a river and a wooded area with a mountain range in the background.
