I just heard about this cave today, and it intrigued the heck out of me, so I started doing some research.
There’s these caves in France called the Chauvet Pont d’Arc, and they have really old, really awesome cave paintings in them. Mostly they’ve come back into public interest because of some dude making a documentary about it, which you can read more about in detail here and also see the trailer.
I’ve also read a lot of nonsense about “oh there was gas in there that made people hallucinate” and so they drew “horrible monsters”. Yeah, you can see those here and read the descriptions. Nobody seems to have had much problem with it until the new documentary came out. Seems half-human half-animal creatures are found in most cultures.
Anyway, all that blather aside, from a purely artistic standpoint, the cave paintings are really, really good.
Considering most cave paintings are limited to stick figures, the detail on these are amazing. You can clearly recognize the horses, lions and rhinos. Not bad for an artist in a cave with no reference material in front of him. I think what I love the most are the sketchy lines to imply lots more of each creature.
