Parietal art

Extracted from the Wikipedia article Rock art.
Background
Parietal art is a term for art in caves; this definition usually extended to art in rock shelters under cliff overhangs. Popularly, it is called "cave art", and is a subset of the wider term, rock art. It is mostly on rock walls, but may be on ceilings and floors. A wide variety of techniques have been used in its creation. The term usually is applied only to prehistoric art, but it may be used for art of any date. Sheltered parietal art has had a far better chance of surviving for very long periods, and what now survives may represent only a very small proportion of what was created.
