Moonrise over the sea Sun Caspar David Friedrich (1774-1840)

The picture has something of this: sunset, evening, backlit, water, ocean, sea, dawn, seashore, silhouette, beach, rock, dusk, light, recreation, landscape, people, silhouetted, reflection.
Perhaps it’s a painting of a man and a woman sitting on a rock looking at the ocean with a sailboat in the distance and a lighthouse.
