Comment: From the back of the book:

Harmonics in Astrology represents the first major attempt in history to develop a truly coherent model of astrology based on sound philosophical first principles & observational & experimental evidence. As such, this great classic is one of the most important books ever written in the field of astrology & should be read by everyone who seeks to arrive at a deeper understanding of astrological concepts & a truly reasonable basis for their study & practice. With his penetrating analysis & reconstruction of astrology's fundamental principles, Addey shows in Harmonics in Astrology that, apart from the planetary "gods" themselves, all astrological effects can be understood in terms of Number & Cycle. In so doing he reconnects astrology with its roots in the ancient teaching of Pythagoras & Plato whilst at the same time liberating astrological concepts from the tyranny of dogmatism & unquestioned traditions, providing students & researchers with a new freedom to explore the intimate bonds between heaven & earth.

Comment: Notes adapted from the dust cover:

This book offers a stimulating & provocative feast of previously unpublished observations & insights. John Addey was in the midst of preparing this volume when he passed away in 1982. The various completed sections & chapters which he left have been pieced together with other previously unpublished material to provide a text in line with Addey's intentions. In this book, John Addey demonstrates how harmonic theory & principles not only clarify the work of Michel & Francoise Gauquelin, but also provide a systematic set of principles on which a wider astrology can be developed.

Prior to my conceptualization of the twelve signs of the zodiac as energies that radiate from the earth itself, John Addey's Harmonics was the previous, comprehensive theory of astrology and how it actually works. In Addey's case, he started in the 1950's with statistical analysis of the birth data of 970 people over 90 years of age and had a very hard time of it.

The first chapters in this book tell the story of Addey's struggle, and his use of applying and separating orbs to determine an overall wave form. Which eventually became the basis for astrological harmonics. Which is the process of dividing a specific collection of natal charts (which are circles) by different whole numbers to see what planetary positions resonate to any given division. Such was the birth of harmonics.

In his subsequent books (above), as well as the books based on his work (below, see also David Cochrane, Astrology for the 21st Century), Addey builds on his discovery. This book, uniquely, documents the struggle, and reveals the excitement of discovery and initial exploitation.

This book was first printed in 1976, but was out of print for many years. It was reprinted in 2004, but there were copyright problems and so the edition was withdrawn. These have now been fixed and I am glad to welcome back this critically important book.

Notes and references


David Hamblin, who describes himself as being in the autumn of his life, has had an ongoing love-hate relationship with astrology. Back in the 1960's he was initially attracted to the psychological aspects of astrology. He was then greatly influenced by John Addey's book on Harmonics (above) and wrote the first good follow-up to it, the out-of-print and much-missed Harmonic Charts (Aquarian Press, 1983) before deciding that perhaps astrology wasn't really real and that he shouldn't be having anything to do with it. Which he voiced in Gary Phillipson's excellent Astrology in the Year Zero, of 2000. Hamblin's problem was that he could find no rational justification for astrology. Which is the problem with a rational world, that it wants and expects explanations when so often none can be had. I myself have rectified this and will be impressing my (very rational) explanation of astrology upon the world as the years pass: Fundamental astrological energies come from the earth itself. These earth-based energies fluctuate over time in harmony with the rest of the planets. Much the same way the sheer volume of sound at a rock concert comes from speakers powered by the local power company. Not from the players themselves, who merely direct and supervise an external (to them) electrical flow. So it is with the earth and planets, but I digress.

Not content with easy or final answers, Hamblin is now back with another book, this one on astrology and number. In a pure sense, numbers are harmonics, which makes this a book on harmonic astrology. Unlike Addey (or David Cochrane), Hamblin here does not chop the natal chart up and then recombine to get something new. He has a different and I confess a somewhat vague method of determining what prime number, from 1 to 31 (or 6, a product of 2 x 3) a chart vibrates to. Hamblin gives calculation instructions in the Appendix. Those of you who have difficulty in calculating natal charts will probably have difficulty with this.

The main chapters in this book delineate the prime numbers as related to specific natal charts. Chapter 18, on interpretation, reverses the scheme. In 18, Hamblin starts with charts of British Prime Ministers and then deduces their appropriate number. I took a short cut: My chart is dominated by oppositions, the full Moon chief among them. So I went directly to Twoness, where instead of reading about love-wisdom of the metaphysicians, I read Hamblin's notes on confrontation, opposition, division and separation. Which is pretty much how I understand planetary oppositions. For each prime number there are numerous examples, each will full birth data, but none with actual charts. You can, of course, easily set up the charts for further study. For each prime number, Hamblin gives concluding remarks, where he sums up factors common to all the charts with that number in them. These are quite well done.

As a whole, the book is on the esoteric side, but is most excellent.
