Barmouth Estuary with Cader Idris, North Wales John Sell Cotman (1782-1842)

The picture has something of this: water, landscape, transportation system, nature, sea, boat, wind, ocean, mountain, rock, lake, sky, sand, recreation, outdoors, watercraft, vehicle, beach.
Perhaps it’s a painting of a boat in a body of water with a mountain range in the background and a man standing in the water in the foreground.
