Below is a YouTube presentation associated with this book, made after its publication in 2012. It is part of a series of films made with Anthony Blake over a weekend, in preparation for a seminar in the United States later that year – called The Politics of Number.
I was employing an octave model for the precessional cycle of about 25,920 years which appears to have been understood in prehistory and seeped into the mythic record in many interesting ways as presented in the ground-breaking book, Hamlet’s Mill. By Classical times, Plato refers to the Great Year and the classic number for this of 25,920 is a canonical number probably assumed due to Pythagorean ideas about the primacy of the factors 2, 3 and 5 found to pre-determine ancient musical tuning theory, the subject of my fifth book: Harmonic Origins of the World.
Precessional Time saw my early attempt to give the early number sciences a developmental history up to the point where they emerged in the ancient world having measured the size of the Earth. This was the story of the fourth book, Sacred Number and the Lords of Time. The manuscript of the 6th book, Angelic Transmission through Sacred Number, now submitted, turns to the spiritual context for this developmental history, having been necessary for the development of the modern mind.
