Charles-Francois Daubigny – Landscape with Cattle by a Stream Part 1 National Gallery UK

The picture has something of this: landscape, tree, outdoors, dawn, sheep, nature, sky, water, grass, hill, mountain, livestock, sunset, agriculture, scenic, cattle, farm, evening.
Perhaps it’s a painting of cows grazing in a field with a river in the foreground and trees on the other side of the painting, with a sunset in the background.
