Virgil’s Tomb by Moonlight, with Silius Italicus Joseph Wright of Derby (1734-1797)

The picture has something of this: landscape, rock, mountain, outdoors, sky, tree, scenic, nature, daylight, temple, light, valley, stone, water, architecture, archaeology.
Perhaps it’s a painting of a man sitting on a rock in the middle of a forest with a full moon in the sky above him and clouds above him.
