This post comes together at the crossroads of three trajectories. The first, mentioned in this post, is the potential that the Watchers are the zodiacal constellations. The second is Aryeh Kaplan’s (Sefer Yetzirah in Theory and Practice) discussion of the two serpents in Kabbalistic lore, one being Draco the constellation, the other being the ecliptic. The third is a vision I had a while ago around spirits dancing down toward the earth on the back of a great snake.

There are two major contenders for the source of the geomancy’s dispersion in the last couple of millenia: West Africa or the Middle East. It is quite possible that neither are the final origin, that a still older cultural substratum pre-exists both. What we can say about that older substratum, if it exists, will nonetheless require us to pass through its more recent points of transmission.
