Landscape with a Man Washing His Feet at a Fountain, after Poussin David Cox (1783-1859)

The picture has something of this: tree, water, landscape, beach, dawn, outdoors, nature, sunset, people, sky, temple, rock, mountain, sea, light, architecture.
Perhaps it’s a painting of a group of people sitting on the ground in a wooded area with a fountain in the foreground and a distant town in the distance.
