Parietal art

Paintings in the Chauvet Cave
A painting of the Virgin Mary in the Calnegia valley in the Swiss Alps. Unlike most parietal art, this painting is modern.

Parietal art is the archaeological term for artwork done on cave walls or large blocks of stone. One of the most famous examples of parietal art is the Grotte Chauvet in France.[1] Also called "cave art", it refers to cave paintings, drawings, etchings, carvings, and pecked artwork on the interior of rock shelters and caves. The purpose of these remains of the Paleolithic and other periods of prehistoric art is not known. However, some theories suggest that these paintings were not solely for decoration as many of them were located in parts of caves that were not easily accessed.

Age

Over 300 caves have been discovered in Spain and France that house parietal art from prehistoric times. Spectacular decorated caves have also been found in Africa (e.g. Namibia), Argentina, India, China, Australia and other locations. Cave art was discovered in the 19th century, long before absolute dating was possible, and the antiquity of the art was much debated. Some scholars at the time developed a typology that was overthrown when AMS radiocarbon dating became available.[2]

Interpretations

Initial interpretations of the art at Lascaux and in other related grottoes suggested that the paintings and engravings were decorative, or just art for art’s sake. Further analysis at the tail-end of the 20th century suggested that the cave art had deep links to prehistoric rituals promoting fertility and successful hunting. Recent studies have found a systematic sequencing in the renditions of horses, aurochs (an extinct ancestor of domestic cattle), and stags,which corresponds to seasonal characteristics of each species representing Spring, Summer, and Autumn respectively.[3]

Other rock art

More generally, the somewhat later rock art of the Iberian Mediterranean Basin covers over 700 caves and rock shelters with mostly painted art in a rather different style, with far more human figures.

Preservation

After its discovery, Lascaux quickly became a major tourist attraction. Its caretakers realized that the equilibrium in the cave’s climate, which had kept the images intact for tens of thousands of years, was being disrupted by so many people visiting the cave, and it was closed in 1963. Around 2000, the cave became filled with a fungus that many blamed on air conditioning, the use of high-powered lights, and too many visitors. The fungus had to be painstakingly removed by hand; currently only a few scientific experts are allowed to work inside the cave, and just for a few days a month.[4] The most representative bacterium (Pseudonocardia sp.) and fungus (Fusarium sp.) from the microbial communities of a cave containing paleolithic paintings were isolated and their growth on natural substrates assessed. Development was analyzed with and without supplemented nutrients (glucose, ammonium, phosphate, peptone). Results showed that the assayed bacterium on natural substrate was able to develop best at in situ temperature and that the addition of organic nutrients and/or phosphate enhanced its growth. The growth of the assayed fungus, however, was limited by low temperature and the availability of ammonium. These results confirm a differential behavior of microorganisms between the laboratory and the natural environments and could explain previous invasion of fungi reported for some caves with prehistoric paintings.[5]
