There are a number of caves near the village of Montignac, in the Dordogne département. One of these caves contains some of the best-known Upper Paleolithic art. Most of the paintings are realistic images of large animals. Many of these animals are known from fossil evidence to have lived in the area at the time. The site of Lascaux was added to the UNESCO World Heritage Sites list in 1979, under the name of the Vézère Valley.
Dating[change | change source]
Unfortunately, none of the colors used in Lascaux are coal based. Therefore, a direct dating of the paintings is not possible. Despite this, Lascaux was one of the first sites where radiocarbon dating was used. That way, the coal in the fireplaces was dated to about 17,000 years ago. H.Breuil himself thought that the site was older, about 31.000 to 22.000 years old.
There are some disagreements about dating the site. The paintings seem to date from 17,000 to 15,000 years ago. Artifacts were also found in the cave, which seem to be older. The original dating was to about 26,000 years ago.
Most archaeologists believe that the age of about 17,000 years is accurate for the following reasons:
- All the paintings seem to have approximately the same age
- No object has been found that would allow to date the paintings to 22,000 years or older
- The tools that were found in the cave correspond to those used 17,000 to 15,000 years ago
- All radiocarbon datings show an age of about 17,000 years, which corresponds to the findings above.
Discovery and problems[change | change source]
The caves were discovered on 12 September 1940. By 1955, about 2000 people visited them every day. In 1968, the original cave was closed to the public, and a system of air conditioning was installed. The cave paintings were restored and replicas of several paintings were created in other caves nearby, known as Lascaux II and Lascaux III. Today, the original cave is no longer accessible to the public.
In 2000, another problem emerged: Certain kinds of fungi started to grow in the original cave. These are extremely resistant to the usual fungicides used, even to formaldehyde. The fungus lives in symbiosis with a bacterium which is capable of destroying the fungicide. Therefore, the fungicide needs to be combined with an antibiotic to kill the bacterium as well.
As of 2006, the situation is more or less under control. The original caves are now sprayed with the fungicide/antibiotic every fortnight. Special workers need to clear the cave walls by hand, removing the mycelium which grows despite the treatment.
