Harz Landscape Janus Genelli (1761-1813)

The picture has something of this: tree, landscape, mountain, fall, river, water, fog, dawn, nature, wood, mist, lake, sunset, outdoors, hill, light, people, scenic.
Perhaps it’s a painting of a mountain landscape with a river running through it and people on horseback on the other side of the river, with mountains in the background.
