In December 1994, three explorers squeezed through a crack in a limestone cliff in southeastern France and stood up inside an untouched Ice Age art gallery. This episode explores the Chauvet Cave, sealed by a cliff collapse 29,000 years ago that preserved cave bear hibernation hollows, fossilized skulls, torch swipes on the walls, and a child’s footprint from roughly 25,000 years ago that may be the oldest accurately dated human footprint in existence.

We look at why the art itself caused a crisis in archaeology: over thirteen species dominated by cave lions, leopards, hyenas, and woolly rhinos rather than prey animals, a debated bison-woman composite figure, red ochre hand stencils sprayed from the mouth, a possible volcano, walls scraped clean as canvases, 3D shading etched into limestone, and overlapping legs that animate under flickering firelight. Then we cover the more than 80 radiocarbon dates that placed the main phase in the Aurignacian period around 37,000 to 33,500 years ago, overturning the assumption that art evolved slowly from crude to masterful.
