AZILIAN PEBBLES

Examples of Azilian pebbles. These painted pebbles from the prehistoric Magdalenian age have been thought to be a form of writing or perhaps the ancestor of writing. Recent investigations, however, imply that a form of astronomical notation, itself a form of writing, existed in Crô-Magnon times, as early as 30,000 years ago.
