A Shepherdess with her Flock near a Stream Charles Emile Jacque

The picture has something of this: sheep, cave, nature, tree, rock, group, mammal, subway system, water, grotto, stalactite, livestock, light, landscape, people, inner surface, outdoors.
Perhaps it’s a painting of a shepherd tending to a flock of sheep by a stream, with a tree in the foreground and a shepherd in the background.
