New Firmicus Maternus Translation

Introducing the Mathesis

The Mathesis of Julius Firmicus Maternus is a very large and influential astrological work written in Latin in the early 4th century.  It is one of the longest and most prominent works in the Hellenistic tradition.  The four most notable texts of the Hellenistic tradition that were written prior to 400 CE, are, in my opinion, this Mathesis, the extremely lengthy Anthology of Vettius Valens (2nd century), the Tetrabiblos of Ptolemy (2nd century), and the shorter Introduction by Paulus Alexandrinus (4th century).

Mathesis and Sect

One of the great things about the Mathesis is that there are countless examples of sect in action.  Numerous interpretations of planets in houses are given, and we see the sect principle illustrated in nearly all of them, as even a malefic planet in sect in a house is judged able to produce some good there, while even a benefic planet out of sect is accompanied by some problems or instability.

For example, this from Book 3, p. 77 of Bram’s 1975 translation:

18. Saturn in  the ninth house will make famous magicians, renowned philosophers,  or  temple  priests  noted  for  their  reputation  for  magic. According  to  the nature of the signs  he also makes seers, diviners,  and astrologers. These are always outstanding  in their responses. Some carry on the rites of tempIes or are in charge of rituals. Sometimes they become long-haired  philosophers or  interpreters of dreams.

19. Saturn  in  this  house  by  night  indicates  wrath  of  the  gods  and hatred of emperors, especially if the waning Moon is moving toward him in any way.  But greater evils are  predicted  from  gods and emperors if Mars  from  any direction  is  in  aspect  to Saturn and  the Moon.

Eight Books of the Mathesis

The Mathesis is a book of natal delineation with a few timing techniques thrown in for good measure. This means that you get a cookbook approach at times, which probably shouldn’t be taken literally as some sort of pronouncement of the gods, but rather used to gather illustrations of broad principles that will allow you to make more accurate judgments in your chart work (and Maternus himself says as much near the end of the fifth book).

The 8 books are topically written as follows:

  1. Introduction: Reasons why astrology is important and useful.
  2. Fundamentals: Signs, houses, aspects/regards, and other basics.
  3. Planets in Places: A few more advanced fundamentals and then a cookbook-style delineations given for each planet in each place by day and night, as well as Mercury with each other planet in each place, and the Moon in the sign of the Lot of Fortune applying to each planet.
  4. The Moon and some special topics: In depth delineation of possibilities with the Moon, including its regards, applications, and separations in a natal chart, then disparate sections on the Lots of Fortune and Spirit, the chart ruler, length-of-life, profession, different degree types (full and empty, masculine and feminine), and then additional Moon considerations.
  5. The Zodiac and Divisions: Delineation of the different signs in each place, the delineation of the planets in the terms of each planet by day and night, concluding with some advice as to consider the whole picture and not just make pronouncements based on single factors such as a single planet in a sign.
  6. Aspects: Some additional material on places, some delineation of fixed stars, but primarily a lengthy set of delineations on planetary aspects or regards, including complex aspect situations, plus some of predictive material on each planet as chronocrator (lord of the time).
  7. Special Delineation: This is a book on delineating special topics, such as birth condition, deformation, slavery, illness, family, marriage, sexuality, children, power/fame, occupation, and so forth.  At the end of Book 6, Maternus notes that this Book 7 will present the more complete picture of astrological practice.
  8. Errata and Fixed Stars: Much of this is commentary on various special degrees, constellations, and other things of note to Firmicus.

Check out the New Translation

Many have hoped for a new translation of the Mathesis by someone well-versed in ancient astrology, because the earlier 1975 translation by Jean Rhys Bram had some confusing passages and possible mistranslations.  James Holden, an astrologer specializing in ancient astrology and translation, produced this new, sought-after, 620 page translation.



Free Ancient Astrology Books | Valens, Ptolemy, Maternus

It is rather exciting time in the study of ancient astrology.  In addition to the fact that most of the Hellenistic and Persian source texts available in English today were first translated in the last two decades, it is also the case that a lot of material has become available online.

Decent translations of the Tetrabiblos, the Mathesis, and the Anthology have become available to read for free online.  Click here to read the Tetrabiblos.  Click here to read and/or download Mathesis.  Last year, something amazing occurred in traditional astrology, as classics scholar Mark Riley released, for free on his website, his full translation of The Anthology of Vettius Valens, the first full English translation ever released.  Be sure to download it. Therefore, 3 of the 4 pivotal early texts are available online.  Also available for free online is an English translation of the Treatise of the Fixed Stars by Anonymous of 379 (click here), which is the most notable ancient text on the effects of the fixed stars.  It’s going to take a long time before traditional astrologers can even digest this large volume of freely available work, making this a very exciting time to do traditional astrology.

Besides noting the available texts here, I will also continue to provide and update the list of links to online texts on the homepage of the Ancient Astrology Wiki.
