Precession of the Equinoxes

Precession of the Equinoxes is a term commonly used to describe the gradual change in the orientation of the rotational axis of the Earth. This involves a slow process that takes about 26,000 years to complete. The 2nd century BC astronomer Hipparchus is generally thought to have discovered precession(a).

Harald A.T. Reiche offered an astronomical interpretation of the Atlantis story, based on precession; a concept discussed at length in Hamlet’s Mill [0524] by Santillana & Dechend, who were colleagues of Reiche at M.I.T. Their view is that “myths were vehicles for memorising and transmitting certain kinds of astronomical and cosmological information.

The African Humid Period (11,000-5,000 years ago) is attributed to the effects of precession. It gave us a ‘Green Sahara’ now associated by some modern researchers, including Sarantitis, Howard, and Kelley, with the time and location of Atlantis.
