Twelfth-Parts | 3. Dahmer, Turner, and Dignity Revisited

Introduction

In the previous articles, I discussed the use of the twelfth-parts. These are also known as the dodecatemoria or the duads/dwads. For a review of the twelfth-parts and their use, please see the first and second article  Here and in future posts of the series, I’ll be revisiting analyses from other articles on the site to look at the twelfth-part positions.

A Return to Sign Dignity

In my articles on dignity, I’ve pointed out the folly of using sign-based dignity to evaluate the beneficence or maleficence (i.e. benefit or harm) of a planetary signification. Overall, dignity has been a chart factor that has been far over-emphasized by traditional astrologers. It is to traditional astrologers what “Mercury retrograde” is to modern astrologers – a convenient but inaccurate crutch.

Dignity as a Separate Concept is a Distraction

It is my opinion, dignity as a separate concept is unnecessary. Dignity as a separate concept is a redundancy in most cases when it appears to work . Generally, a planet in its own domicile is made more prominent because its ruler is itself – a type of feedback loop. In that sense, a planet with dignity has a type of strength or prominence.

There are also more specific instances of a benefic or malefic interpretation in which dignity is not really at the heart of the issue. For instance, the Moon in Scorpio is linked with difficulty (especially in a day chart) by the Moon being ruled by a malefic. It is similar with Venus in Scorpio or Aries.

More commonly, the astrologer is overlooking more important factors such as place, sect, and the influence of malefics or benefics when they defer to dignity. Mercury in Pisces is a Mercury linked with benefit (Jupiter). However, if someone with that configuration had a speech impediment, the astrologer would be quick to blame Mercury in fall. Perhaps, they missed that Mercury is in the 6th house and dominated by Saturn.

The Curious Case of Jeffrey Dahmer and Ted Turner

The first of the articles on dignity compared the charts of Jeffrey Dahmer and Ted Turner. Dahmer had a whopping 4 planets in domicile, with only 2 peregrine and only 1 in fall – a chart with an unusually high amount of dignity. Ted Turner has no planets in domicile or exaltation, 1 planet in fall, 3 planets in “detriment” (for those who use detriment – I don’t), 2 planets peregrine, and only 1 planet with positive dignity – an unusually ill-dignified chart.

I found Dahmer and Turner to be the perfect minimal pair for explaining the trouble with dignity, not just in terms of beneficence and maleficence, but also for strength.  I do use some sign-based significations like domicile, exaltation, fall, triplicity, and bound, for prominence myself. However, I give them less stress than typically given to them. I place more stress on advancing/retreating, being in a stake, stations, phasis, and relationship to the lights (including being in a domicile of a light). I explore strength indications at length in the lessons.

Dignity is Not Beneficence and Not Stature

Obviously, Dahmer’s life was not filled with more joy, goodness, and positive productivity than that of Turner, as might be expected if dignity pertained to beneficence and maleficence.  Similarly, while Manetho, Maternus, and other Hellenistic astrologers suggested that one’s stature and power depend to a great deal on the number of planets in domicile in one’s chart, it is clear that this also cannot be the case. We would expect the lack of dignity in Turner’s chart to suggest he is very much held back. Similarly, we would suggest that Dahmer has immense social mobility.  Therefore, while I believe that being in domicile, exaltation, triplicity, or bound is reinforcing of a planet, it is obvious folly to rely on dignity for beneficence and for evaluating social stature.

Enter Twelfth-Parts

With the above said, it is interesting that the twelfth-parts tend to reveal much more strength and beneficence in Turner’s chart.  The twelfth-parts also reveal additional weakness and maleficence in Dahmer’s chart.

Dahmer’s Twelfth-Parts

Dahmer’s Natal Chart with Twelfth-Parts along Outside of Wheel

In Dahmer’s chart, there are 4 planets in domicile and 1 in fall but 3 twelfth-part planets are in fall (and 1 in “detriment”), with none in domicile or exaltation.

Twelfth-Part Mars in X Ruled by the Moon and Square to Mars

More importantly, the twelfth-part of Mars, occupies the powerful 10th place (Dahmer’s “achievements”), square to its natal position. The square to its natal position increases its malice (see quote in previous article on twelfth-parts that square or oppose their natal positions).

Mars-Moon combinations, such as the one in the natal chart, have significations that relate to bodily violence. The twelfth-part of Mars is in the sign of the Moon and square to the natal Moon-Mars. The twelfth-part of the Moon in Scorpio, a domicile of Mars, in the bound of Saturn (significator of death), and in the 2nd place (one of the dark places). Therefore, the Moon-Mars bodily violence signification is reinforced in many ways.

An Even Darker Character

The Moon is relevant for character, especially in terms of irrational impulses and instincts. Ptolemy identified it with the irrational part of the soul (see Tetrabiblos, Book III, Ch. 13).  The Ascendant and Mercury are also relevant for character delineation and are in the bounds of Jupiter in the natal chart. The Moon, Mercury, and the Ascendant have their twelfth-parts are in bounds of Saturn. The twelfth-part of Mercury is additionally with the twelfth-part of Saturn in the 11th, pertaining to friends and groups.

The ruler of the Ascendant, the twelfth-part of the Ascendant, and the ruler of the twelfth-part of the Ascendant are also relevant to the character.  We find the ruler of the Ascendant, Venus, to be in the 8th pertaining to death, fear, and harm, in the bound of Saturn. The twelfth-part of the Ascendant is in that same place and bound. Additionally, that twelfth-part is also ruled by Venus. Therefore, three important character significators are piled into the bound of Saturn, the planet of death, in the 8th place, the place of death, ruled by Venus, planet of sexuality.

Turner’s Twelfth-Parts

Ted Turner’s Natal Chart with Twelfth-Parts on Outside of Wheel

The 3 planets in “detriment” in Turner’s natal chart are in their own domiciles in the twelfth-parts. Saturn in fall sees its twelfth-part in “detriment”. However, detriment was not a distinct concept in Hellenistic astrology. Therefore, Saturn’s twelfth-part is actually in triplicity and the sign of the sect light. Being in triplicity and in a sign of a light, especially the sect light, is strengthening.

Lighting Up the 10th House

The Sun has its twelfth-part in the 10th with the Moon, in a sign of Mercury and bound of Jupiter. Both twelfth-part lights in the 10th provide an additional indication of power and influence.

Benefics Gracing the Lights

Additionally, the twelfth-part of the sect benefic, Jupiter, falls into the 12th, the place of the Sun, Fortune, and Venus. This links benefits to their significations.  The other benefic, Venus, lands in the 11th, her domicile, the place of the Moon.  Thus both benefic twelfth-parts occupy the places of the lights linking them with fortunate circumstances.

Conclusion

Twelfth-parts give very important additional information about planets and points in the natal chart.  Dignity is often a redundant consideration, but it can play a role in terms of planetary prominence and reinforcement. If you are going to consider dignity as a strength consideration, then be sure to also examine the twelfth-parts.

The ancients stressed how the twelfth-parts are responsible for major modulations in planetary signification within a sign.  In this sense, dignity relating to twelfth-part positions may be even more important than that related to natal positions. More work research is needed in this area.  In any case, the twelfth-parts positions reinforce or contradict significations in the natal chart. It is these reinforcements and contradictions that help us to correctly interpret the chart.

Twelfth-Parts | 2. The Secret Second Chart

Secret Charts

For, if you want to explain the entire substance of the astrological significations from the efficacy of the dodecatemories and from the terms in which they are found, you will not be mistaken; for the Babylonians attribute the supreme power of [astrological] decrees to the dodecatemories, but Ptolemy to the antiscions, [and] we to both.  (Maternus, Book III, Ch. 9, #14, Holden trans., 2011, p. 170)

So, you thought you just had one astrological chart, but in Hellenistic astrology you have two.  Then again, maybe three. The secret charts are found by examining some projected positions for chart factors.

Twelfth-Parts

The second chart I allude to is the chart of the twelfth-part positions. Twelfth-part positions were noted as a fundamental basic of astrological technique by nearly every Hellenistic astrologer. Their use was urged most strongly by Julius Firmicus Maternus. These are typically marked along the natal chart to keep a reference to natal chart houses.  I explored what the twelfth-parts are and how they are calculated in the introductory article.

Antiscia

The third chart that I alluded to is something that appears to be more idiosyncratic to Maternus. It is the use of antiscia positions as yet another chart body-double.  I explored this use of antiscia by Maternus very briefly near the end of my article on sign symmetry.

Maternus attributes this use of antiscia chart positions as secret positions to Ptolemy, though this is a false attribution. Maternus is the only Hellenistic source I know of that uses this third set of positions.  On the other hand, the dodecatemoria or twelfth-parts are indeed Babylonian in origin, and their use was widespread among Hellenistic astrologers.

Paulean Twelfth-Parts

In the last article, I expressed that Paulus presented an idiosyncratic variety of twelfth-parts in which the position in degrees and minutes are multiplied by 13 rather 12. I was recently confronted by a footnote by James Holden (footnote #2, p. 18, 2009) in his translation of Rhetorius in which he noted that there is evidence in surviving cuneiform tablets that the two different methods of projecting twelfth-parts existed in Babylonian astrology. In other words, according to Holden multiplying by either the more common 12 or the 13 as used by Paulus, then projecting from the beginning of the sign, were both used (Holden cites “Mesopotamian Astrology” by Koch-Westenholz).

If it is in fact the case that the 13-fold variety does also have Babylonian origins, then at least among the Hellenistic astrologers, it was a less popular variant. Manilius, Dorotheus, Ptolemy, Valens, Maternus, Hephaistio, Porphyry, and Rhetorius (as well as later astrologers) employed or expressed preference for the 12-fold variety.

The Importance of the Twelfth-Part Positions

I was originally skeptical about the use of the twelfth-part positions. I didn’t think they represented an important or informative addition to the natal chart positions. I’m sure many readers initially feel the same way.  Therefore, I want to stress that the twelfth-parts were mentioned as a basic of astrological technique by nearly every Hellenistic astrologer. Many of them, including Manilius, Maternus, and Rhetorius, felt it necessary to stress how important they are despite how easy it is to overlook them.

… the genitures differ in a single constellation, because the individual signs vary on account of the distribution of their divisions and modulate their respective powers in the dodecatemories.  (Manilius, Book II, #710-712, Goold trans., 1977, p. 139)

And the method of dodecatemories is a necessity in nativities; and I also put down the astrological significations of these so that some might use them not just as in a secondary work.  (Rhetorius, Ch. 18, Holden trans., 2009, p. 18)

Now I shall show briefly how you may inquire about the dodecatemories, for some think that they can find the entire substance of the nativity from them, and they intimate that whatever is concealed in the delineation can be discovered from the dodecatemories.  (Maternus, Book II, Ch. 17, #1, Holden trans., 2011, p. 59)

Basics of Use

The twelfth-part positions are used just like natal positions. They give additional information and reveal significations that might be missed from looking at the natal chart alone.

Cognition Usage Isn’t Just About Cognition

Even the interpretation of cognition usage (discussed in the last article) is along these lines, though it is for horary or consultation charts.  Masha’allah (in On Hidden Things) discussed multiple signficators for the querent’s thoughts or intentions. One of them was the ruler of the Ascendant. However, Masha’allah expressed that the best significator is the twelfth-part of the Ascendant and its ruler. In other words, the twelfth-part Ascendant and its ruler are used just as the Ascendant and its ruler to give information about the querent and the matter itself.

Hellenistic Astrologers Using Twelfth-Parts as the Secret Chart

Paulus: Twelfth-Parts Also Show Benefic/Malefic Indications

We get a sense of this all-purpose use in Paulus, even though he used the 13-fold ones. In Ch. 22 of his Introduction, he noted that the twelfth-parts of benefics occurring in important places signify very good things for the person. By contrast, twelfth-parts of malefics occuring in such places indicate bad things. Benefics produce fortunate circumstances where they occur, and malefics produce difficulty, and it is the same with the twelfth-parts of each.

Maternus: Delineation of a Planet or Point Includes Delineating its Twelfth-Part

Maternus laid out the use of twelfth-parts in Book II of the Mathesis.  There he instructed us to look at numerous things but stressed the place, the ruler, and the bound ruler of the twelfth-part. We are are also to look at sect and the interactions between planets in ways that he discussed for regular planets (for instance that there is greater harmony between the waxing or full moon and diurnal planets).  All in all, it seems that Maternus wants us to look at twelfth-part positions as on an almost equal footing as natal positions, examining things like place, sign ruler, bound ruler, regards/aspects, and special configurational indications.

This is further stressed in Book III, when each chapter on a planet ends with Maternus admonishing the reader to also check out the planet’s twelfth-part. Apparently, we are to look at the same factors discussed with reference to the natal planet. In this way we will not miss some important indication that is in the twelfth-parts but not the regular natal chart, as everything should be in one or the other.  Maternus even advised to check the twelfth-part of the Lot of Fortune after discussing Fortune’s delineation  (Book IV, Ch. 4) .  Again, the clear lesson is to delineate the twelfth-part as you’d delineate the planet.

Rhetorius: Twelfth-Part Positions Signify in Configurations Too

But what of the relationship of a twelfth-part to its same natal point, such as the twelfth-part of the Sun to the natal Sun?  Rhetorius treated of this in Ch. 60 of his Compendium.  A twelfth-part trine its natal position increases the beneficence or fortune signified by the planet, but one opposed to its natal position increases the maleficence or difficulty signified by the planet.

Rhetorius also discussed how the twelfth-parts of malefics falling in places can make things more difficult and the twelfth-parts of benefics easier, similar to what Paulus mentioned above.  He put particular stress on the twelfth-part of the Moon in relation to the nature and social standing of the person.  In his delineations of twelfth-parts he particular stressed the influence of the ruler of the twelfth-part. Some delineations also involve regards/aspects from natal planets and even the qualities of the signs, such as human and quadrapedal.  That the twelfth-part delineations of Rhetorius encompassed all these things lends support to the idea that delineation of the twelfth-part is very much like delineation of a natal planet or point.

Delineation Example: Steve Jobs

In the next several posts on twelfth-parts, I’ll be digging back to analyses from older posts on the blog and showing how twelfth-parts add valuable information.  I will kick this off by taking a brief second look at the chart of Steve Jobs for the rest of this post.

In one my first posts, in October 2011, I discussed the natal chart of Steve Jobs and some of the most important general planetary strength considerations, showing that his Mercury is much stronger than one might think from a cursory glance.  Before reading on, I urge the reader to give that post a quick review by visiting it here.  While stations and phasis may not be appropriate to twelfth-parts, the twelfth-parts can tell us additional information about the strength of Mercury.

Steve Jobs’ Natal Chart with Twelfth-Parts on Outer Wheel

In the original analysis I noted that Mercury is probably the strongest planet in the chart in terms of having a generally pervasive influence over the life in a broad way, as it is strongly stationing direct, making an appearance (in phasis), advancing, and ruling the 1st.

Twelfth-Part MC Conjunct nMercury; Twelfth-Part Mercury Strong

Looking at the twelfth-parts we find further indication of the significance of Mercury by the twelfth-part of the MC being conjunct Mercury.  This and the fact that Mercury’s twelfth-part is advancing in the 11th which is a strong and fortunate place. It is in a sign of a light (Cancer, home of the Moon, which is the sect light of the chart), while actually with the twelfth-part of the sect light. These are all additional indications of the strength of Mercury.

Twelfth-Part Mercury Fortunately Conjunct nJupiter

The twelfth-part of Mercury is in the bound of Jupiter (as is the natal Mercury), and is very tightly conjoined to Jupiter, in the place of Jupiter’s Joy, and in the sign of Jupiter’s exaltation. These things all connect Mercury with fortunate and lofty Jupiterian themes, but are not as strongly expressed in the natal chart itself.

Mercury posited in the 11th house from the ASC will make talented persons, indispensable for all activities, and those to whom the conduct of great business affairs is entrusted; but then it denotes greater duties if it was conjoined to Jupiter by a favorable aspect.  (Maternus, Book III,Ch. 3f, #23, Holden trans., 2011, p. 147)

More Twelfth-Parts

The twelfth-part of Venus, the sect benefic, occupying Virgo, a house of Mercury, further emphasizes this fortunate quality of Mercury.  Also note that the twelfth-part of Jupiter falls right onto the Sun in the chart. The twelfth-part of the Sun is in the place of the Sun’s Joy with the twelfth-part Ascendant. The Moon’s twelfth-part is strongly advancing toward the MC. She is also with the lord of the Ascendant and Jupiter (as well as Saturn).  Additionally, the twelfth-part of Fortune is conjunct the Moon, the sect light.

Key Information

As one can see, the twelfth-parts not only help us to get more information out of the chart about the prominence of Mercury, but also showcase fortunate circumstances connected to Mercury. These are important features of this person’s life that are reflected in the chart with the twelfth-parts but would be easy to miss from the natal chart without them. We see many additional indications that the chart is of someone with great social mobility and very fortunate circumstances linked to Mercury.

Conclusion

Twelfth-parts are not a trivial matter. In chart delineation, it is vital to see which indications are repeated in many different ways. Such indications are stronger and more important, allowing us to say something meaningful about the life. The twelfth-parts are a vital and important part of chart delineation. If you’re looking at a chart without the twelfth-parts, you are missing a huge chunk of the information in the chart. Without this important information, you can rest assured that you will reach the wrong conclusions. Similar indications of something in the chart may be repeated without your knowledge while other indications you might think are important may be contradicted by the twelfth-parts. If you’re serious about accurately reading a natal chart add the twelfth-parts to your chart readings today.

Twelfth-Parts | 1. Introducing the Dodecatemory of the Signs

Twelfth-Parts

There is a secret key to the zodiac. Inside every zodiacal sign there are another twelve-signs. This division of the zodiac dates back to Babylonian times and was a key element of Hellenistic and early medieval astrology, but is extremely neglected today. Key elements of natal delineation and timing have been lost due to ignorance regarding this important feature of the zodiac. In this article, I explore the origins and use of twelfth-parts.

Pray examine now a matter trivial in appearance, yet one of great moment, which does not permit description of itself save by a Greek word.  I speak of the dodecatemories, of which the name proclaims the principle.  The signs each consist of thirty degrees, and every total is further divided by twice six; the calculation therefore shows that in each division there are two and a half degrees.    (Manilius, Book 2, 693-700, Goold trans., 1977, p. 137)

Who Used the Twelfth-Parts?

Hellenistic Astrologers

In addition to Manilius, the twelfth-parts were used by almost every Hellenistic astrologer. Early Hellenistic astrologers who used twelfth-parts include Dorotheus of Sidon (1st Century CE) in Book I, Ch. 8 and other sections of Carmen, Ptolemy (2nd Century CE) in Book I, Ch. 22 of the Tetrabiblos, and Vettius Valens (2nd Century CE) in multiple sections of his Anthology. Julius Firmicus Maternus (4th Century CE) strongly advocated the use of twelfth-parts in Book II, Ch. 17, and many other sections of his Mathesis. Additionally, Porphyry of Tyre (3rd Century CE) in Ch. 39 of his Introduction to the Tetrabiblos used twelfth-parts, as did Hephaistio of Thebes (5th Century CE) in Book I, Ch. 18 and in Book III of his Apotelesmatics. Rhetorius (7th century) also used twelfth-parts in Ch. 18 of his Compendium.

Early Medieval Astrologers

The twelfth-parts continued to be a basic component of astrological technique as practiced by later Perso-Arabic astrologers of the early medieval period, including Sahl, Masha’allah, Abu Ma’shar, al-Qabisi, Abraham Ibn Ezra, and more.

Abu Ma’shar made extensive use of twelfth-parts in his predictive methods. He made over 20 mentions of twelfth-parts in his work on predictive natal astrology, On the Revolutions of the Years of Nativities. Ma’shar advocated their use in nearly all predictive techniques. He explicitly advocated their use in solar returns (see Book I, Ch. 5-6; see Book II, Ch. 3 in relation to the profected Ascendant), lunar returns (see Book II, Ch. 1), primary directions (see Book III, Ch. 1), and transits (see Book V, Ch. 9). The twelfth-parts are key not only to natal delineation but also to predictive astrology.

Pre-Hellenistic Use

However, the use of the twelfth-parts predates Hellenistic astrology.  The twelfth-parts. like the twelve-sign zodiac itself, have their origins with the Babylonians, who used them in omen lore at least as far back as the 5th century BCE. Therefore, the twelfth-part divisions of the zodiacal signs are nearly as old as the regularized twelve-sign zodiac itself.

What are the Twelfth-Parts?

The twelfth-parts appear in the earliest strains of Hellenistic astrology. They are also known as dodecatemory/dodekatemoria,  duodena/duodecimae, or dwad/dwadashama. As the 1st Century astrologer, Manilius, explained in the opening quote, the twelfth-parts are divisions of each astrological sign into 12 equal parts. Each of the twelve parts are assigned a zodiacal sign beginning with the greater sign itself.

Finding Twelfth-Parts

Some authors, including Manilius, give two ways to calculate these, both leading to the same result. One way is to think of the first 2.5° as belonging to the sign itself, the second to the next sign, and so on until you get to the last 2.5° which belongs to the sign preceding the greater sign.  For instance, if Mercury were found at 28° Scorpio, then it would be in the last 2.5° of the sign, and thus its twelfth-part would be Libra.

A second method is used for greater accuracy. We take the degrees and minutes of the position within the sign and multiply it by 12, then add that many degrees to the beginning of the sign the planet is in.  For instance, with Mercury at exactly 28°00′ Scorpio, we would take 28 and multiply it by 12, yielding 336, then we would add this to the beginning of the sign Scorpio, so 30 would bring us to Sagittarius, 60 to Capricorn, 90 to Aquarius, and so on until we get to Libra with 6 degrees left over; the twelfth-part of Mercury would therefore be 6°00′ Libra in this case.

Chart Calculation of Twelfth-Parts

The FREE, open-source, traditional astrology program, Morinus, has twelfth-part calculation built-in. Some of the developers of the program have been very kind to me and gave given me the chance to check out the functionality before it was implemented.  It is great to have a program that can lay out the twelfth-part positions quickly and visually, because as we’ll see, these positions are informative and early astrologers placed importance on them.

Morinus Chart Appearance Options

In order to pull up twelfth-parts in Traditional Morinus, after installation using the instructions I’ve provided, first pull up a chart. Then hold Shift and press A, or click on Option from the top navigation menu and click Appearance I. Select Dodecatemoria from the In Chart options and click OK. The chart will then have the twelfth-part positions apparent around the outside.

Bruce Lee’s Natal Chart with Twelfth-PartsVariations

Some Variations

Manilius Division

Manilius asserted that the twelfth-parts are further divided into 5 segments of half a degree each, assigned to the five non-luminary planets, Saturn, Jupiter, Mars, Venus, and Mercury (see Manilius, Astronomica, Book 2, 738-748).  However, Manilius didn’t specify the order that the planets are assigned to these subdivisions, and no other early astrologers addressed these divisions.  Typically, the Chaldean order, either from slowest to swiftest (Saturn, Jupiter, Mars, Venus, Mercury) or the reverse (Mercury, Venus, Mars, Jupiter, Saturn) is suggested.  While the first one of these orders is certainly the most logical, supported by the use of such order in many other types of zodiacal division from decan to monomoiria, we can’t be sure. I don’t recommend the use of these subdivisions in practice.

Paulean Thirteenth-Parts?

It is also worth noting that Paulus Alexandrinus (4th Century CE) provided an idiosyncratic type of twelfth-parts. The twelfth-part explanation in Paulus is most likely in error, as he multiplies the position by 13, rather than by 12.  He gives a paragraph explaining his justification for multiplying by 13 rather than 12, but there isn’t much logical sense in the explanation in my opinion. Paulus seemed to imply that multiplication by 13 was necessary to allow the 12th parts to come back to the sign that the planet is in. This is hardly a noteworthy argument, as the first 2.5° of the sign already fall to that same sign in the standard system.

Commentary on Paulus

In the commentary on Paulus by Olympiodorus the Younger (6th Century CE), he found it necessary to explain the more typical form of twelfth-part first to preface the discussion. He then explained the idiosyncratic Paulean form. As far as I know, this idiosyncratic form of twelfth-part isban innovation of Paulus and was used by Paulus only, so I will not pursue it further here.

And we say: the ancient Egyptians used to call it the 12th part, since the number is found in the position of each star multiplied by 12.  However Paulus, having come later and examined the matter closely, [said] that the multiplication by 12 is never returned to the same zoidion where the star is, where we seek the dodekatemorion — but often the dodekatemorion of the star happens to fall in the same zoidion where the star is.   (Olympiodorus, Commentary on Paulus Alexandrinus, Ch. 21, Greenbaum trans., 2001, p. 102)

How were Twelfth-Parts Used?

The twelfth-parts produce a secondary zodiacal position for each planet and point in the chart. It is as if each point is projected into an additional hidden zodiacal position.

There are four main ways in which the twelfth-parts were used in Hellenistic astrology: 1. The twelfth-part of the Moon gave indications regarding the physical sex of the person; 2. The twelfth-part of the Sun gave indications about the Ascendant when it was unknown; 3. The twelfth-part of the Ascendant revealed thoughts/intentions; 4. Twelfth-part positions gave additional information about planetary significations that are on par with the natal positions of the planet.

I will briefly explore three of these four uses; for sex, finding the Ascendant, and interpretation of cognition.  However, I want to make it clear to the reader, that the last use is by far the most fruitful and important.

Sex of a Person from the Natal Chart

Both Dorotheus (Book I, Ch. 8 of Carmen) and Valens (Book IX, Ch. 8 of Anthology) used the sex of the sign of the twelfth-part of the Moon for delineation of the native’s sex.

Dorotheus

For Dorotheus, the basic idea is that if the Moon’s twelfth-part is in a male sign (i.e. a Fire or Air sign) then the native is male, but if in a female sign (i.e. an Earth or Water sign) then the native is female.  However, there are some exceptions that can override this indication of the sex of the sign of the twelfth-part of the Moon.

The exception are as follows: 1. Sun, Moon, and Ascendant are in signs of the opposite sex, 2. the Light of the opposite sex (i.e. Sun is masculine and Moon is feminine) is in the Ascendant in a sign of its same sex, 3. planets of the opposite sex occupy the 1st and the 7th, 4. both Lights are in signs of the opposite sex and a planet of the opposite sex rules the Ascendant (example given is of both Lights in masculine signs and Jupiter ruling the Ascendant, this overriding a feminine twelfth-part of the Moon to indicate a male child).

Valens

For Valens, the sex of the sign of the twelfth-part of the Moon and the sex of the sign occupied by that sign’s ruler give strong indications for sex of the child.

Results

This method is poor for predicting sex.  For instance, Kurt Cobain has Sun, Moon, and Ascendant all in feminine signs, which would override the fact that the twelfth-part of the Moon in his chart is in Sagittarius, a masculine sign.  Additionally, the ruler of the twelfth-part of the Moon is Jupiter, which is also in a feminine sign.

Cobain’s Natal Chart

One might argue that perhaps Dorotheus was incorrect and the twelfth-part of the Moon should be given the primary consideration in this endeavor. However, examine the chart of Traci Lords. Her Ascendant is in a masculine sign, Sun and Moon in feminine signs. The twelfth-part of the Moon is in a masculine sign, and its ruler, Saturn, is also in a masculine sign, so if they were given primary consideration we’d judge her to be a man.

Traci Lords’ Natal Chart

Junk Technique

In conclusion, we cannot rely upon the twelfth-part of the Moon methods of Dorotheus or Valens to guess the sex of a person by the birth chart. Perhaps Dorotheus and Valens have given us leads for the eventual development of a technique for guessing the sex of an individual from the chart that involves use of twelfth-parts. So far we don’t have a reliable technique for such a determination.

Twelfth-Parts for Finding the Ascendant

Another one of the more spurious uses of the twelfth-parts is to rectify the sign of an individual’s Ascendant when it is unknown.  It is Valens that discussed this use of twelfth-part of the Sun in Book I, Ch. 4 and Book IX, Ch. 7 of his Anthology.  It is only one method among many rectification methods discussed by Valens.

The method involves first knowing if the person was born by day or night and knowing the Sun’s position accurately enough to be able to find the sign of its twelfth-part. The Ascendant for a day birth will either be the sign opposite the sign of the Sun’s twelfth-part, or one trine to that sign, with preference given to the “left” trine (i.e. the one that is 120° after the sign of the twelfth-part of the Sun). If it is a night birth, then it will be one of the signs opposite to these, again with the same preference.

Example

For example, if someone was born with the twelfth-part of the Sun in Taurus, then for a day birth the most likely Ascendant would be Virgo, but could also be Scorpio or Capricorn. If a night birth then the most likely Ascendant would be Pisces, but could also be Taurus or Cancer.

Results

I’m a day birth with the twelfth-part of the Sun in Taurus, and my Ascendant is none of the three relevant signs, nor any of the three signs for night births.  A technique that narrows the Ascending sign to one-fourth of the signs of the chart, but still doesn’t give you an accurate indication is not a very valuable technique.

Interpretation of Cognition

One of the more fascinating niche uses of twelfth-parts is in the interpretation of cognition. This use was common for consultation charts, and later in medieval horary astrology. The technique originates with unknown Indian astrologers and Hephastio of Thebes. Importantly, it was adoped by Masha’allah.  The basic idea is that the twelfth-part of the Ascendant gives indications about the thoughts and intentions of a native or a querent (the one asking the astrologer to divine the answer to a question). The native is really concerned about matters pertaining to the house represented by the twelfth-part of the Ascendant. The qualities and conditions of that place such as the quality of the sign, its domicile lord, and occupants of the sign are all relevant to the native’s true concerns.

The Search of the Heart

Dr. Benjamin Dykes explored this use of twelfth-parts in considerable depth in his translation of, and commentary on, Hermann of Carinthia’s “The Search of the Heart”.  I highly recommend this work of Dr. Dykes for those interested in delving into this use of twelfth-parts in greater depth. Dykes explores the technique in his introduction, translates a work which uses the technique, and provides commentary on that work. Additionally, he includes appendices with further discussion and translations, including a table of the entire 144 significations given by Hephastio for each twelfth-part of the Ascendant.

Horary Astrology

The primary use of this technique in medieval astrology was to anticipate a client’s area of concern. This usage appears to have started in Indian and/or Hellenistic use of consultation charts. This use of consultation charts preceded, and likely lead to, the development of horary astrology.

Masha’allah in On Hidden Things (from the Works of Sahl and Masha’allah translated by Dykes in 2008) suggested that the twelfth-part of the Ascendant provides the best indications regarding a querent’s intention in an horary reading. If a planet is in that place then you look to that place as signifying the person’s intention. If the place is empty then you look to the place of its ruler.

Masha’allah: Twelfth-Part Ascendant and its Ruler

In an example given by Masha’allah (the same example was given by Hermann of Carinthia centuries later but attributed to the Indians), the Ascendant was the 12th degree of Aries, which has its twelfth-part in Leo. As the Ascendant was in Aries, Leo was the 5th place from the Ascendant.  Leo was empty in the horary chart and the Sun was in Libra, the 7th. Masha’allah surmised that the question involved the 5th in the condition of the 7th or the 5th seeking the 7th. The indication was that of a child seeking a woman (or seeking the querent’s wife).

Masha’allah said that if the Sun had been in the 6th then it would’ve suggested a question about a sick child, and so forth.  As you can see the stress in this technique is primarily on the significations of the place/house. One can combine the significations of the place with its ruler, in the sense of the place being fulfilled by or meeting the condition of the ruler’s place. This is one of a few different techniques given by Masha’allah and later authors for interpreting the intentions of a querent.

Chart Projections

Used with natal charts the technique puts an interesting twist on the idea of personal focus and fulfillment.  The ruler of the Ascendant shows a particular pull towards a certain place in the natal chart. Consider its accompanying themes and significations. Similarly, the twelfth-part of the Ascendant and its ruler may reveal a personal emphasis for the individual.

In the next article on twelfth-parts, I’ll explore their use in natal delineation in more depth. I’ll draw heavily on Maternus, who found in twelfth-parts the secret to more accurate delineation. I highly recommend the use of the twelfth-parts of all chart factors. I also recommend their use in predictive astrology as advocated by Abu Ma’shar. However, let’s start by looking at twelfth-part of the Ascendant.

Hitler’s Twelfth-Part Ascendant

Hitler had the twelfth-part of the Ascendant in Leo with the greater malefic Saturn, in the bound of Mercury. It is in the networking and popularity-oriented 11th House (house of friends), in the sign of leadership, Leo. Its ruler, the Sun, was in the 8th, pertaining to death and harm. The twelfth-part of Hitler’s Sun is also in the 8th, and its ruler too is in the 8th. This gives interesting additional valuable information that we can add to our knowledge that his Ascendant lord (Venus) and the sect light of his chart (the Sun) are in the 8th of his natal chart.

Using the Masha’allah-style of place combination, we might suggest that he has some intention to achieve a Saturnine standing in groups through death, fear, and destruction. I also think that Leo and the solar element both contribute meaning here, as does the bound of Mercury.

Dahmer’s Twelfth-Part Ascendant

Looking at Jeffrey Dahmer’s chart, we find the twelfth-part of the Ascendant in the 8th of death. It is also in the bound of Saturn. It is conjunct Venus, the lord of the Ascendant, which is also the ruler of the twelfth-part. They are both in the same bound of Saturn in the 8th.  Therefore, the personal intentions and focus on Saturnine-Venusian, death, fear, and destruction themes are very pronounced.

Start playing around with twelfth-parts in natal, horary, mundane, and electional charts. For electional astrology, putting the twelfth-part of the Moon in strong and good places is recommended by Sahl and others. Experiment, and if you have any revelations, feel free to share them in the comments.
