Chauvet Cave, France The 36,000-year-old paintings in Chauvet are incredible. It is not just their state of preservation, it is that they record a lost world. Bison, Aurochs, Lions and, Rhinoceros are all recorded on the cave's walls. Caves often act as time capsules preserving what things were like in the past. In the case of Chauvet we have an evocative record of what long-extinct animals looked like recorded by attentive artists. There is one detail that sometimes gets overlooked about this cave. The wall is covered by scratch marks from cave bears (Ursus spelaeus). These huge bears hibernated in caves and presumably left the scratch marks while stretching when they wokeup.
Seeing the paintings in Chauvet was a profound experience and led me to create the non-profit @ancientartarchive. We use 3D and VR technology to share the experience of standing in front of ancient artworks.
