Art of Forecasting using Solar Returns

Anthony Louis

An outstanding addition to the limited list of books on Solar Returns. The author bases his work on the technique of 17th century astrologer Morin (whose work he has also translated in other books), giving a solid historical background in the process. Filled with examples and case histories, this is an in-depth and rigorous read.

Solar returns are a popular tool amongst astrologers these days. They first became widely used by the medieval Arabian astrologers, and then Western astrologers began using the technique as part of their predictive system. In the 16th
century William Lilly and John Gadbury wrote about solar returns but not a great deal. Most of the detailed study was done by Jean Baptiste Morin in the 17th century. French astrologer Alexander Volguine (1903-1976) spent a long time studying Morin’s work to develop a detailed system of his own.

Anthony Louis has brought all this research together and put it in a language that we can readily understand today. There are plenty of examples throughout the book to help illustrate his techniques. The solar return, or revolution, is treated by the older authors as part of a greater predictive system. Nothing could occur unless it was promised in the nativity. Progressions and transits were used to time events, while eclipses, Arabic parts, solstice and equinox points and fixed stars were also considered. Solar returns were never judged alone.

Louis also looks at some contemporary authors who do not always use traditional rules. He gives their ideas without judgement even though he may not agree with them. Later in the book Louis also puts a cookbook of aspects in solar returns. At the end there is the chapter on bringing it all together and an excellent further reading list.

This book has a huge amount of well researched material giving the reader inspiration as well as all the practical knowledge one would need to forecast using Solar Returns.

This very comprehensive well researched text offers readers unparalleled detailed explanations of the major techniques available for the interpretation of Solar Return charts. Well known for his work with Horary astrology, Antony Louis’ fascination with the work of William Lilly’s contemporary Jean-Baptiste Morin (a contemporary of Descartes), as well as his interest in the work of Alexandre Volguine, is evident throughout this thorough text. One of the great skills of the author is his ability to dance back and forth between traditional and modem approaches, including the writing of Mary Fortier Shea, James Eshelman and Ray Merriman, as he invites us to question and consider all possibilities. In fact, rather than merely presenting theories, Antony Louis skilfully engages us throughout this somewhat complex information with his own helpful research and suggestions. In the true manner of real teaching, this invites us as readers to embark on our own exploratory journey of true learning. ·

The basic premise we are introduced to at the start of the book is that ”the solar return is a key that in any given year unlocks certain potentials of the birth chart. A complete picture will not emerge unless it is related to the birth chart.” Having set the context, Antony addresses the issues of precession as well as timing related to death, and considerations related to Solar Returns when the birth time is unknown. The ample interesting examples throughout this thoroughly researched book consistently bring the theory alive. There are also many helpful aids such as keywords for the houses, planets and the Solar Return ascendant, a final cookbook section on aspects in Solar Returns, and an excellent recommended reading section. The step by step outline for delineating a Solar Return together with the detailed case study at the end of the book is particularly useful.

I will leave you with the words of the author: “a systematic approach to the Solar Return chart helps in mining all the treasures buried in the annual chart” bringing forth certain potentials when ”there exists a concordance between the annual chart and the nativity, the current natal directions and progressions, the current eclipses, the lunar returns and the ongoing transits.”

I would suggest that this excellent book is ideally suited to astrologers who have a good knowledge of the basics.

Books on solar returns, like those on electional astrology, are far and few between. For many years the practice of solar returns has been more an option for astrologers rather than a necessity, and this is primarily due to the lack of adequate and researched
texts on the subject. As a result, the subject has been caught up in contradictory methods and fraught with complications such as whether or not to precess or to relocate annual or monthly returns. But now Anthony Louis has come to the rescue and has produced a work that both builds upon and tests the sources of much of our original knowledge of returns, that of Jean-Baptiste Morin and his 20th century follower Alexandre Volguine.

In The Art of Forecasting using Solar Returns, Anthony Louis provides the reader with a solid historical background on the technique and lays out clearly how Morin, one of the greatest astrologers of all time, used it in the 17th century. He then proceeds to test this methodology rigorously with example after example – most from recent history featuring recognizable celebrities and also a few persons known to the author. Every
aspect of return interpretation is raised and examined, including those promoted by the few modern-day writers on the subject. By the end of this dense and thorough book the reader is offered a methodological summary and worked example.

To my knowledge, nothing this complete has ever been published and a serious reader will find the work to be all they need to guide them through the interpretation of solar and lunar returns, as well as their progression through time. Louis also tackles the thorny problem of precessed returns – do they work and what does one do with them?

Unlike other authors who take an either-or view on this topic, Louis shows the uses of both in example after example. Unfortunately, Louis does not engage in the same level of testing in regard to the relocation issue, though he mentions it as a technique used by both Morin and Volguine, the primary sources for his exposition of return techniques.

Overall this is a complete work and one that I would enthusiastically recommend as the one book to acquire on this subject.”

From the Preface, by the author:

What if there were a method that would enable you to learn how the promise of your birth chart would unfold in the year ahead? What if that method would allow you to utilize everything you already know about astrology and simply apply it from a new perspective? Well, there is such a method and it is called a Solar Return (or Solar Revolution, to use a more antiquated

This book is about Solar Returns, specifically about how to use your Solar Return in conjunction with your birth chart annually to forecast the major themes and events of your life. The focus of this text is on technique. It is decidedly not a cookbook, plenty of which already populate the market, though you will find cookbook-like sections that catalogue information for easy reference. By the time you finish reading this book, you will have a solid foundation in delineating a Solar Return chart within the context of the nativity. Our approach will be to study the techniques of the masters who have devoted themselves to understanding solar revolutions, and the outcome will be an enhanced ability to think like an astrologer and also a greater
appreciation of the potentials inherent in the birth chart.

The approach in this book is not dogmatic. In astrology as in much of life there are many ways to skin a cat (my apologies to cat lovers), and we shall consider several of them. I have selected for inclusion techniques from the literature that have proved useful in my own experience, and I have added a few methods of my own for the reader to try. Learning is best by doing, and many example charts are included for study. From these well-documented cases the reader will be able to judge whether these procedures are valid.

I come to Solar Returns from horary astrology. Having spent
considerable time learning the techniques of traditional horary, particularly the method of William Lilly, I became fascinated with the ideas of Jean-Baptiste Morin, a brilliant French contemporary of Lilly. So great was my interest that I translated into English Morin’s Book 18 on the dignities and debilities of the
planets. This text represents my own struggles to piece together traditional ideas with modern astrological concepts while remaining grounded in empirical reality and the evidence of verifiable case histories. These cases are based on well-documented stories that make excellent illustrations of technique.

After completing the manuscript, I noticed an unintentional emphasis on death, accidents, life-threatening injuries, murders, and similar misfortunes. Such a focus on the dark side occurred in part because these types of events are common in the traditional textbooks, especially the writings of Morin. It is likely that I am drawn to such themes because of the prominent Pluto and
Saturn in my own nativity, and indeed my entrance into astrology was characterized by a study of the planetary conditions active at the time of my mother’s untimely death. Yet a deeper reason may underlie the focus on issues of mortality in this text. Only after finishing the first draft of the manuscript did I have the “aha” experience that the Taurus Ascendant of my 2005 Solar
Return, which was active during the year that I was writing this book, was drawing my attention, outside of my awareness, to my natal 8th house with its Taurus cusp. Ah, the wonders of astrology!
