Nicolas Poussin – Landscape with Travellers Resting Part 5 National Gallery UK

The picture has something of this: water, landscape, tree, daylight, outdoors, people, recreation, rock, light, vehicle, sunset, seashore, dawn, beach, evening, mammal, river.
Perhaps it’s a painting of a group of people in a wooded area with a river in the foreground and a castle on the other side of the painting.
