The goat herd of Genzano, 1843, The Phillips Collectio Jean-Baptiste-Camille Corot (1796-1875)

The picture has something of this: landscape, outdoors, tree, daylight, sky, scenic, water, mountain, seashore, nature, rock, hill, recreation, beach, summer, park, architecture.
Perhaps it’s a painting of a man sitting on a hill next to a horse and a man kneeling down on the side of a hill with a building in the background.
