Blombos Cave
Earliest known rock drawing

In 2011, archeologists found small rock fragment among spear points and other excavated material. After extensive testing for seven years, it was revealed that the nine red lines drawn on the rock were handmade and from an ochre crayon dating back 73,000 years. This makes it the oldest known abstract rock drawing. The geometrical markings are an astonishing example of a very early creative behavior. According to the research published in the journal Nature, the find was "a prime indicator of modern cognition" in our species and an ochre crayon was used by early African Homo sapiens inscribed onto the stone.
