Tending Sheep, Bettws-y-Coed David Cox (1783-1859)

The picture has something of this: tree, landscape, water, nature, rock, outdoors, mountain, sky, wood, fall, park, scenic, seashore, light, dawn, river, lake, daylight.
Perhaps it’s a painting of a group of sheep grazing in a wooded area with a stone wall and a tree in the foreground with a mountain in the background.
