Hakkert, Jacob Philip. Villa of Maecenas and the Waterfalls at Tivoli Hermitage ~ part 12

The picture has something of this: tree, landscape, mountain, water, rock, river, dawn, nature, outdoors, wood, light, lake, sky, fog, mist, sunset, valley.
Perhaps it’s a painting of a waterfall with a group of people in the foreground and a castle in the background on a hill above a body of water.
