On September 12, 1940, a French teenager took his dog for a walk - a simple everyday event, but it was to lead to one of the most stunning archaeological discoveries of all time.

Robot, the dog, ran into a hole created by a fallen tree. Ravidat threw some stones into the hole.

Returning later with some friends and a teacher he climbed down the hole and began to explore.

The boys discovered what were to become known as the Lascaux cave paintings – estimated to be between 17,000 to 20,000 years old and excitedly described by experts as “the cradle of art”.

Over 600 parietal wall paintings cover the interior walls and ceilings of the cave.

The age of the paintings is now usually estimated at around 17,000 years

IMO this should be called the Robot cave paintings
