The story is told in terms of the discoverers. Our guide, whose quaint English was easy to listen to, called the discoverer "the first modern polluter" because in the picture he was smoking a cigarette. (Times haven't changed that much; many French, for reasons unknown, still smoke even thought they know better. I think there may be an insight here, but it escapes me.)
But can you imagine dropping into an underground space and being greeted by this?
There can be no doubt that this, in the original, is one of the most remarkable artifacts of man. As mentioned with the Grotte de Niaux, current anthropological thinking is that the animals depicted, not being game for the painters, held spiritual significance, and the caves were places of worship. Hence the interesting symbols ... although here, 17,000 years BP (Before the Present), the magic number of dots in a row appears to be 13, not 11.
On the right above, can you see that there's a black bull and a red horse? The bull is the biggest cave image known, five meters wide. We are told that the painters reproduced the original "exactly" using the same pigments and, where possibly, techniques ("They cheated a little") but the vividness of the colors is so much greater than Niaux, I have to wonder.
It would have been lovely to rest with the images, and soak them in, but we were hustled right along because another group was coming through ... although our guide was patient and cordial, she kept us moving, and it felt a little like an assembly line.
By the way: no photos in the simulated cave, so I borrowed these from the cave authorities.
