River landscape Якоб Филипп Гаккерт (1737-1807)

The picture has something of this: tree, water, outdoors, landscape, dawn, nature, river, people, lake, sky, sunset, fog, daylight, scenic, mist, summer, mountain, fall.
Perhaps it’s a painting of cows and people in a wooded area by a river with a castle in the distance and a castle on a hill.
