The Lake and Town of Nemi John Robert Cozens (1752-1799)

The picture has something of this: landscape, mountain, volcano, nature, rock, eruption, water, sky, outdoors, snow, scenic, winter, geology, calamity, lake, hike, beautiful, valley.
Perhaps it’s a painting of a mountain with a body of water in the foreground and a castle on a hill in the distance with clouds in the background.
