Tens of thousands of years ago, before there was writing, ancient peoples told stories through symbols. With colors made from minerals, they painted pictographs on cave walls, rock shelters, and ledges. They chipped and pecked the surface of stones to make petroglyphs.

Pictograph — Lascaux, France, 12,000 to 17,000 years old
