While we’re on the subject of geometry, perhaps Euclidean principle should get a mention?
The Cederberg Mountains lie just 350 kms north of Cape Town and contain an extraordinary heritage of rock art by the San Bushmen. There are thousands of sites which record a visual story of their beliefs and the environment. Some of the paintings are executed with such artistry and flow with grace and beauty.
Here “The Archer” has perfect proportions and it’s clear that the artist understood the principle of Euclidean geometric construction techniques. The bow is the arc of a perfect circle, centered on the archer’s left shoulder. The bowstrings are of equal length and the archer hands are perfectly placed on a radius of the circle.
The painting is found in a site on the Sevilla Trail area which is dated back 1600 to 2000 years and could possibly go back even further to 8000 years.
