View of Tivoli with the Temple of Vesta Francois Boucher (1703-1770)

The picture has something of this: water, tree, river, outdoors, rock, landscape, nature, waterfall, environment, motion, scenic, daylight, stream, park, cascade, mountain.
Perhaps it’s a painting of a mountain scene with people and animals in the foreground and a castle in the background, with a waterfall.
