“Aside from the animals, there are nearly a thousand abstract signs and shapes we cannot interpret and also several negative hand stencils, as they are known by art historians. These are the paintings that most interest me. They were created by pressing one hand with fingers splayed against the wall of the cave and then blowing pigment, leaving the area around the hand painted. Similar hand stencils have been found in caves around the world from Indonesia to Spain to Australia to the Americas to Africa. We have found these memories of hands from 15,000 or 30,000, or even 40,000 years ago.
These hand stencils remind us of how different life was in the distant past. Amputations, likely from frostbite, are common in Europe and so you often see negative hand stencils with three or four fingers. And life was short and difficult. As many as a quarter of women died in childbirth. Around 50% of children died before the age of five.
But they also remind us that the humans of the past were as human as we are, their hands indistinguishable from ours. These communities hunted and gathered and there were no large caloric surpluses so every healthy person would’ve had to contribute to the acquisition of food and water.
And yet somehow, they still made time to create art, almost as if art isn’t optional for humans.”
