Landscape with St Matthew and the Angel Nicolas Poussin (1594-1665)

The picture has something of this: water, outdoors, daylight, people, river, recreation, tree, landscape, vehicle, lake, group, two, scenic, sky, rock, leisure, seashore.
Perhaps it’s a painting of a man and a woman sitting on a stone wall next to a body of water with a castle in the distance in the background.
