The important subject of trigon (“triplicity”) lords deserves a special topic devoted to it, so I am starting one in response to a question from Ms. Hamilton on the Miscellaneous Questions topic.
First some historical considerations. If my suspicions are correct about the dating of Antiochus’ lost introductory writing are correct, he may be one of the first to report them. The first thing of interest is that they are not associated with the elements in that text, but rather with “winds”, which in turn are correlated with the four cardinal directions; such an association persists up to the time of Ptolemy. To the best of my knowledge, Valens is the first surviving source that associates them with the elements, although he does not do this as if he were innovating.
The second thing of note in that text is that the author does not give the trigons planetary rulerships at all. We do find the rulership scheme that became common in medieval astrology in Dorotheus and Valens. This consists of two principal rulers and a cooperating one. As far as the trigon consisting of the Crab, the Scorpion, and the Fishes is concerned, the diurnal ruler is Aphroditē, the nocturnal one Arēs, and the cooperating one Selēnē. Ptolemy, of course, ignores the cooperating trigon lord altogether for the other three trigons, but in the case of this particular trigon has Arēs as the principal trigon lord both by day and by night, with Aphroditē cooperating by day and Selēnē by night. I believe I know the reason for this apparent deviation from tradition by Ptolemy, but that will have to wait until a future post.
(If anyone does not know the three traditional trigon lords of the other three trigons, or the manner in which their order reverses depending on the sect of the chart, please ask. At the moment I am writing in some haste.)
In lieu of trigon lords of this type, Antiochus had a very different scheme in which the planets do not so much have authority over the trigon qua trigon, but rather the domicile lords of the trigonal images of a given image are understood to be “joint domicile masters” along with the domicile lord of that image itself. For example, Hermēs (for the Virgin) and Kronos (for the Goat-Horned) are joint domicile masters of the Bull along with Aphroditē. Some carry-over of this concept may be found in Book II of the Tetrabiblos. At the 2006 PHASE Conclave, Ken Johnson saw in them the probable origin of the Vedic classification of planets into friends and enemies.
Other points of importance. Valens makes great use of the trigon lords of the sect light in determining the rank or “magnitude” of the nativity. He does not extend the use of trigon lords to any other planets or places in the chart. In fact, no surviving source independent of Dorotheus does this. Dorotheus seems to be “trigon happy”, as he himself reveals at the very beginning of his book.
In particular, I question Dorotheus’ taking of trigon lords of the Lot of Fortune or topical places such as the rising image and the fourth topical place. This seems to me a conceptual faux pas. In several Hellenistic texts, three planets are singled out for special importance in a delineation of the chart. These are the domicile lord of the Ascendant, the domicile lord of the Lot of Fortune, and the trigon lord(s) of the sect light. These three planets are so important that they are often collectively called “the planets having a relation to the nativity”. This implies that the trigon lord of the sect light (and possibly of other planets) represents a mode of rulership for planets analogous to that of the planetary rulership of a topical place (“house”). This is clearly different than the function that a domicile lord has to a planet resident in its domicile. Such a relationship is based on a guest/host relation, and it is very different than the manner in which a planet is allotted the responsibility for certain topics in the native’s life by virtue of having authority over the image that is in that topical place. For obvious historical reasons, the medieval astrologers follow Dorotheus in this practice. However, I am of a mind to bracket it as inconsistent with the intentions of the founders of Hellenistic astrology.
It is worth noting that rulership by trigon is considered by early Hellenistic authors to be in a different category from that of rulership by domicile, exaltation, or confines (“bounds” or “terms”. I believe that we can hold Ptolemy IR-responsible for having put trigon rulership under the same general category as the other modes. This is one of the many problems that I have with the medieval treatment of the almuten.
In Book II of Valens, where the technique of taking the trigon lords of the sect light is introduced, it is very clear that the first trigon lord has authority over the first part of the native’s life, the second over the second, and the third cooperates with both the first and the second periods. The cooperating lord has nothing to do with a third portion of the native’s life, as is often said in medieval texts. As a matter of fact, Valens has some interesting rules for timing the change-over from the first to the second trigon lord. I believe that if the medieval astrologers had had Valens at their disposal, they never would have claimed such a thing. Dorotheus is somewhat vague on the topic.
Finally, Valens in various places makes the intriguing statement that in charts of higher rank (according to the technique of examining the trigon lords of the sect light), the malefics function differently. They are actually more benefic for the native, although in the charts of tyrants this is at the expense of suffering for those around them.
I have somewhat feverishly gone beyond Ms. Hamilton’s question, but perhaps this will help stimulate more discussion about this highly important topic.
