Origin and etymology

  • The Abri Blanchard site grew in notoriety following Alexander Marshack’s discovery of the world’s oldest lunar calendar dating back to the early Upper Palaeolithic period of the Stone Age. Marshack’s discoveries became an important aspect of Cometan’s establishment of the historiography of the Astronic tradition, particularly supporting the tradition’s prehistoric origins.
