Jacob Philipp Hackert – Roveto Valley Liechtenstein Museum (Vienna)

The picture has something of this: water, landscape, mountain, tree, nature, outdoors, river, lake, sky, wood, scenic, rock, fall, daylight, summer, valley, hill, reflection.
Perhaps it’s a painting of a mountain landscape with a lake and a herd of sheep in the foreground and a distant mountain range in the distance, with a few clouds in the sky.
