An Arcadian Landscape with stories from the legends of Pan and Bacchus Nicolas Poussin (1594-1665)

The picture has something of this: water, people, tree, landscape, outdoors, group, recreation, rock, leisure, river, two, daylight, mountain, man, scenic.
Perhaps it’s a painting of a group of people in a wooded area with a man and a woman in the foreground and a dog on the other side of the painting.
