Annibala Fountain in Rocca di Papa near Rome Lev Lagorio (1827-1905)

The picture has something of this: mountain, landscape, outdoors, scenic, nature, valley, hill, fog, mist, tree, water, rock, daylight, dawn, sky, volcano, environment, light.
Perhaps it’s a painting of a man riding on the back of a horse on a dirt road in front of a mountain range with a stream running through it.
