San dot paintings

San paintings - Matopo hills of Zimbabwe. Dot patterns - cave art. San people were among the first humans - the oldest people in the world?

Dots are part of a complex system of markings that represent life force - potency. An attempt to represent the spiritual dimension - a mistrust of appearance. Religious iconography.

Also they used a long red line through their paintings on the cave wall - to divide the human from the spirit worlds? Arrrgh can’t remember.
