Prehistoric Paintings: “An Endangered Species”
The most famous prehistoric paintings are found in Lascaux— a complex of caves in southwestern France containing art that goes back as far back as 25,000 years. Discovered in 1940 by four teenagers, Lascaux was first examined by archaeologist Henri Breuil, who developed a system of classification for prehistoric art that was utilized through the 20th century, though its not in use any longer. The cave contains nearly 2,000 figures, in three main categories: animals, human figures, and abstract signs (which may be a language). Interestingly, the paintings (rendered with mineral pigments) and engravings contain no images of what would have been the surrounding landscape or the vegetation of the time—which certainly adds another element of mystery to these fascinating works of art. In recent years, new research has suggested that the Lascaux paintings may incorporate prehistoric star charts. An alternative hypothesis is that this type of art is spiritual in nature, relating to visions experienced during ritualistic trance-dancing. But the jury is still out on their true meaning.
Now, there’s quite a saga associated with Lascaux. The opening of the complex after World War II (in 1948) changed the cave environment. Carbon dioxide from the exhalations of 1200 visitors a day, the presence of light, and changes in air circulation created a number of problems—including lichens and crystals on the walls. This led to a closure of the caves in 1963, to tourists. A replica cave for visitors to Lascaux opened in 1983—nearby the original complex. A limited number of professionals were still permitted in the original caves—for research purposes. In 2001, the authorities in charge of Lascaux changed the air conditioning system in the original complex to better regulate the temperature and humidity. However, an infestation of white mold began spreading rapidly across the caves’ ceilings and walls, which had to be treated with quicklime. In 2007, a new fungus, creating grey and black blemishes, began spreading in the caves. Organized through the initiative of the French Ministry of Culture, an international symposium titled "Lascaux and Preservation Issues in Subterranean Environments" was held in Paris in 2009. It brought together nearly 300 participants from 17 countries, with the goal of comparing research and interventions conducted into the preservation of such environments. The proceedings of this symposium were published in 2011. Seventy-four specialists in fields as varied as biology, biochemistry, botany, hydrology, climatology, geology, fluid mechanics, archaeology, anthropology, restoration and conservation, from numerous countries (France, United States, Portugal, Spain, Japan, and others) contributed to this publication. The Lascaux Cave complex is an excellent example of arts culture getting it wrong—and then working very hard—using many layers of professionals—to make it right. Even with all of the research that’s been conducted—there still remain many unanswered questions. Perhaps one day the original Lascaux complex can be re-opened—without harm to its contents. That’s the goal.
