The Cave of Lascaux
It was Thursday, September 12, 1940. Four French teens were out exploring in the woods off the northern slopes of the Pyrenees. Many years before, an old pine tree fell and left a large hole in the ground. The teenagers were curious and they started to explore the area and fell into one of the most important archeological（考古的） finds of the twentieth century!
There are over a hundred limestone（灰岩）caves in this region of France. Some were inhabited by humans thousands and thousands of years ago. Between 15,000-17,000 years ago, humans painted lively creatures such as cows, bulls, horses, and even cats on the walls of the cave.
Why did they mark these walls? Was it to tell a story? Was it to record a famous battle? There are many mysteries and ancient secrets still waiting to be discovered in the cave of Lascaux. There were dots in many of the paintings. What do these dots mean? Were they meant to record time, a calendar? Deep in the cave, there is a drawing of a "birdman’’. What does this mean? Was it a place for sacred ceremonies? No one knows for sure.

Only a specialist can visit the cave by a special order that must be made out almost a year in advance. Not more than six persons can enter the cave per day.
