Dubois, Guillaume – Berglandschap, 1630-1660 Rijksmuseum: part 3

The picture has something of this: landscape, water, mountain, rock, sea, ocean, seashore, light, daylight, outdoors, scenic, environment, lake, tree, river, volcano, nature, island.
Perhaps it’s a painting of a mountainous landscape with a man on a horse in the foreground and a man.
