Cuyp, Aelbert – Bergachtig landschap met kasteelruïne, 1640 - 1650 Rijksmuseum: part 1

The picture has something of this: outdoors, landscape, sky, water, nature, rock, daylight, desert, mountain, dawn, sunset, geology, eruption, tree, scenic, fair weather, hot, volcano.
Perhaps it’s a painting of a rocky landscape with a man on a horse in the foreground and a man.
