Astrological Book Review: Works of Sahl & Masha’allah (by Benjamin Dykes)
August 7, 2008 by Nina Gryphon
Last month, Ben Dykes published a new translation of the works of 8-9th century Persian astrologers Sahl and Masha’allah. The book is a compilation of 16 shorter astrological works. As Dykes pointed out in his interview with GA, this is not an exhaustive collection of Sahl and Masha’allah’s works. The works that are included have dual value: they are of use to a practicing astrologer, and provide insight into the practice of astrology by the Arabs.
Dykes translated Guido Bonatti’s Book of Astronomy last year, and because Bonatti refers to Sahl and Masha’allah very frequently as his sources, Dykes sought to make the works by the two authors more available to the English-reading public. If Bonatti was only sparsely translated into English (such as his aphorisms, by Henry Coley), Sahl and Masha’allah were translated even less frequently, despite their importance in early medieval astrological practice.
Briefly…
Works of Sahl & Masha’allah is a difficult, dense, but extremely rewarding text. The astrological concepts themselves are not terribly complicated, but we would recommend a working knowledge of planetary dignity and reception, planetary movement, and astronomical phenomena like eclipses. Dykes’s introduction to the text is a must-read, because he explains several specific concepts/phrases recurring frequently in the texts that the reader is unlikely to have encountered before.
Readers interested in the nitty-gritty practica of horary, electional, political, and weather astrology will find very useful material here. However, there is also a nice balance of more theoretical texts on the building blocks of astrology, such as Sahl’s Fifty Judgments, or Masha’allah’s On Reception. Dykes’s easy-to-read translation is a fine addition to a library of the intermediate/advanced working astrologer or astrological history enthusiast.
Book Contents and Structure
The book begins with a listing of text or reference abbreviations, of which there are plenty, Arabic transliterations, and a table of figures. The 80-page introduction by the translator is a must-read, not only for key phrase definitions, but also for a succinct comparison of techniques used by Sahl, Masha’allah and other ancient astrologers, and an explanation of frequently used sources in the text.
Because a book with just one introduction is for weaklings, the book proper begins with Sahl’s Introduction, which is essentially Astrology 101, medieval-style. Here we get the meanings of the signs, houses, aspects, and astrological concepts such as reception. This is followed by On questions, an horary treatise organized by house. Astrologers familiar with William Lilly’s Christian Astrology will see similarities in organization, but the substance is rather different. Topics such as “on a commander setting off to war, or another worried person when he asks about him,” are covered, often in great detail, along with “a question about the age of the winning beast,” such as in horse races.
A short work On the elections, follows, again organized by house-related topics. The last of Sahl’s works in the book is On times, which is a work on methods of timing events in horoscopes. These methods seem most obviously applicable to horary charts, but they could be applied to natal horoscopes as well.
The Masha’allah part of the book begins with “on the knowledge of the motion of the orb,” a cosmological, astronomical, and physical treatise. This is followed by a short work called On the roots of revolutions, and On rains, the former introducing key concepts in mundane astrology, such as solar and planetary ingress charts, and eclipses, with the latter treatise showing how to apply the methods to astrometeorology.
A useful and information-rich treatise, On the revolution of the years of the world follows, focusing on mundane astrology and specific positions of planetary significators, and their meanings. Two treatises on nativities follow, one more of a planet-in-terms cookbook, the latter containing lots of example charts in traditional square format with a paragraph of analysis each.
To shorter treatises follow, On the interpretation of cognition, and On hidden things. The former gives hints to the astrologer for discovering the intention of the questioner, and the latter text is about finding lost objects. The next text is on reception, first discussing the theory, and then its applications to various topics, such as financial questions, and “will I get the kingdom” kinds of questions, with example charts. The last text is What the planets signify in the 12th domiciles of the circle, a kind of cookbook, which could be applied both to natal and horary charts. For example, Saturn in the 12th house gives “impediments which happen in connection with the King, and he will be strong and bold in this, and he will be captured by enemies, and he will be afraid in all of his matters.”
Finally, we are treated to a multipage bibliography and detailed index.
Observations.
As noted above, Works is a very dense, rich book. The ideal way to read it is in small pieces at a time, to better experiment with unfamiliar techniques and concepts. The sheer magnitude of information can be intimidating, though the astrology itself is pretty accessible to a modern reader.
The translator does not pull any punches, and obviously enjoys bringing to light forgotten techniques and astrological concepts. He does not bend the text to shape it to our modern preconceptions. This is good, because it preserves textual integrity, and bad, as many readers might benefit from more familiar terms to help ease into a very different text than they might be used to. Ultimately, however, a translator has to balance integrity with accessibility, and Dykes’s choice, though more demanding of the reader, leaves us with the sense that justice was done to the text.
