Landscape with two bathing children Karl Friedrich Schinkel (1781-1841)

The picture has something of this: tree, outdoors, recreation, daylight, wood, leaf, water, landscape, lush, rainforest, people, park, nature, river, scenic, placid, summer, environment.
Perhaps it’s a painting of a person riding a horse in a wooded area with a house on the other side of the painting and trees.
