A Civita Castellana Rochers Boises Jean-Baptiste-Camille Corot (1796-1875)

The picture has something of this: cave, subway system, rock, stalactite, limestone, grotto, light, mine, tunnel, geology, stone, cavern, dark, ancient, water, mystery.
Perhaps it’s a painting of a forest scene with rocks and trees in the foreground and a stream running through the center of the painting in the middle.
