Pieces of ochre rock decorated with geometric patterns found at Blombos Cave in South Africa, nearly 200 miles from Cape Town, in 2002, have been dated to the Middle Stone Age, equivalent to the European Middle Paleolithic.
"This ocher plaque has marks that may have been used to count or store information. A close-up look at the object shows that the markings are clearly organized. This systematic pattern suggests to some researchers that the markings represent information rather than decoration" (http://humanorigins.si.edu/evidence/behavior/blombos-ocher-plaque, accessed 05-10-2010).Filed under: Archaeology, Art , Communication, Prehistory, Survival of Information, Writing / Palaeography / Calligraphy | Share:
