Astrological Geomancy : http://www.renaissanceastrology.com/astrologicalgeomancy.html
This article was uncovered after the other following interesting articles:
- http://www.ted.com/talks/ron_eglash_on_african_fractals.html In this he talks about how an African tribe was creating a lines in sand, he was obsessed to know about these patterned lines since he was researching on the Fractals and how African culture had included fractals in all their lifestyle. Very interesting seminar. Fractals are based on the beauty of Fibonacci series of numbers.
- Then came this article where different cultures adopted this system. http://en.wikipedia.org/wiki/Geomancy
