I have had the privilege of touring some of the French caves with these paintings, and it is a profoundly moving experience to face a wall of hand stencils that is tens of thousands of years old. From the sizes of the hands, it seems clear that a community had made them, both little children and grown adults. The marks are so incredibly old, and yet it’s easy to visualize the people holding up their hands and blowing ocher on them, leaving a shadow behind. I don’t know if it’s possible to still visit these caves today —- we were on a National Geographic tour led by paleoanthropologist Don Johanson, discoverer of “Lucy”, and he has long since retired —- but it’s well worth your time if you ever get a chance to see them.

I just hope they don’t do what they do in Italy and freshen them up by painting over them

Don't leave out the Americans on that one, especially if there's money to be made.

Thank you for this link. This whole over painting thing, it just, I felt like im the only person on the planet shocked by it. The second I arrive in italy I was told yes thats the painting of the last supper. And I was like wtf, it looks freshly painted. I read a placque which said somethign like ( due to the poor damp conditions of the room) the painting needed constant restoration.

I was like wtf so basically non of this shit is original?

Noone else seemed to even consider this.

Im sure poepl ein the art world come to terms with it, but I dont think anyone outside the field even conceives of what a restoration normally is

Not sure why I got a downvote, maybe there are people who aren't aware of how paintings are restored.

It's not possible to visit the caves for most people. They do have reconstructions of the more famous ones though (Lascaux, Crosquer, ...)
