Zodiac with 24 sectors

1
Hi everyone,

In the "Arkana Dictionary of Astrology", Fred Gettings mentions an ancient subdivision of the zodiac into 24 sectors, meaning that every sign gets subdivided into two equal parts. Such a half-sign was called a hora. However, I am not aware of any ancient astrologer writing about this.

Vedic astrologer Valerie J. Roebuck mentions such a system of "horas" in "The Circle of Stars", but doesn't explain it much. Supposedly Vedic astrology got the idea from Hellenistic astrology.

Any information and / or references any of you can give on the ancient or contemporary use of this concept would be greatly appreciated.

Nothing at the front of my mind, but the word hora means hour, and since a planet passes through all 12 houses in 24 hours - so each house, idealistically, in 2 hours - then a division of a house into two horas is identifying the two hours in each house division. So this is really a break down of the 24 hour day, which is going to have a direct association with the 24 planetary hour rulers for each day. Excuse me if you already knew that and wanted some other sort of interpretative information.

Hi Deb,

Thank you for your astute remark re the planetary hour rulers. Indeed, hora could mean "hour" as well as "double-hour", the latter being correlated with the twelve signs.

Yes, I'm still hoping for somebody having specific information on the 24 sectors as used in astrology, but your thoughts are much appreciated.

Best regards
Michael

Hello Michael,

The hora is one the divisional charts used in Indian astrology. These are collectively called the vargas.

The varga charts are a unique method only employed in Indian astrology to study various aspects of life. Each sign of 30 degrees is further subdivided to generate additional divisional charts. There are 16 divisional charts and they are studied to analyze the finer conditions, strengths and effects of the planets. These charts are also employed to study certain specific aspects of life like spouse, children, parents etc. The hora chart is used especially to study wealth.

The following are the varga divisions:

1. Rashi or the Lagna chart as it is of 30? to study all aspects of life.

2. Hora or one-half of a sign -15? is the varga to study wealth.

3. Drekkana or one-third of a sign ? 10? is the varga to study siblings.

4. Chaturthamsha or one-fourth of a sign ? 7?30? is the varga to study destiny and home.

5. Saptamsha or one-seventh of a sign ? 4?17`8.5? is the varga to study progeny.

6. Navamsha or one-ninth of a sign ? 3?20? is the varga for spouse and many other things.

7. Dashamsha or one-tenth of a sign ? 3?- is the varga to study ones profession.

8. Dwadashamsha or one-twelfth of a sign -2?30?- is the varga to study parents.

9. Shodashamsha or one-sixteenth of a sign -1?52?30?- is the varga to study conveyance.

10. Vimshamsha or one-twentieth of a sign -1?30?- is the varga to study spiritual progress.

11. Chaturvimshamsha or one-twenty fourth of a sign -1?15?- is to study knowledge.

12. Saptavimshamsha or one-twenty seventh of a sign -1?6?40?- is to study the strength.

13. Trimshamsha or one-thirtieth of a sign ? 1?00?- is misfortunes and nature.

14. Khavedamsha or one-fortieth of a sign ? 0?45? is for auspicious & inauspicious effects.

15. Akshavedamsha or one-forty fifth of a sign 0?40? is for all areas of life.

16.Shashtyamsha or one-sixtieth of a sign 0?30? is for all general effects.

If you want follow this up it might be wiser to post on the Indian forum. I am pretty sure there is no comparable system like the vargas in hellenistic astrology. They seem to be unique to Indian astrology.

On the other hand the lots never seem to to have been adopted in Indian astrology.

Yes, I also realised this was the "steps" after posting yesterday - they have a very ancient recognition in Babylonian astrology, but I haven't seen meanings attributed to them in that way that Mark illustrates above.

In traditional Chinese astrology the year is subdivided into 24 so-called li chun, the first one (called "early spring") begins in early February - with the sun at 15 degrees AQU.

From the references Michael gave from Gettings and Roebuck there doesn't seem any doubt they are discussing the Indian varga known as hora.

Its an interesting point whether this has any direct antecedents in hellenistic or babylonian astrology. Or is the common 15? division just a coincidence?

In a recent podcast Kenneth Johnson and Chris Brennan discussed the hellenistic influences on Indian astrology but they seemed to conclude that the varga were an indigenous Indian development.

What Curtis describes above does seem rather different. The distinctive thing about the varga is that a whole new horoscope is generated from these divisions. The closest analogy in western astrology seems to be harmonic charts although the two are not strictly synonymous.

This sounds interesting. Could you say a bit more on this please? What sources are you getting this from?

Its bread and butter technique in Indian astrology. References to the various vargas exist in the very earliest Indian astrological texts we have preserved such as Sphujidhvaja's Yavanaj?takam .

Mark, I may be wrong (alas, I don't have access to the "Arkana Dictionary of Astrology" at the moment) but I was quite sure that, by hora, Gettings was referring to HELLENISTIC astrology. (According to a note I took, the reference would be on p. 237 f.)
Also, Franz Boll: Sphaera, p. 311 ff. speaks about an assignment of the 24 letters of the Greek alphabet to the zoidia by Teukros/Rhetorios which may be relevant here.
By the way, thanks for the "crash course" in vargas. Yep, let's follow this up in the Indian section once we're done with Greece.
The winds of the planets are calculated from their exaltations and the division of each sign into two "steps" of 15 degrees each is outlined.
Curtis, at least based on the Valens translation that I have got, I find it quite unintelligible how Valens is doing this calculation, and what it means. :???: Can you explain it, or refer me to a clear explanation?

Just like Mark, I would love to hear more about this, and know your source.

Interesting, especially in light of the theory that the Chinese and the Hellenistic zodiac are related to each other (Boll).

Many thanks to all of you!

-- Glad you repeated that because I missed it in Mark's post. I don't know a lot about this, but remember it as one of the arguments proposed by Neugebauer for the reason the Sun's ray's extend 15? either side of its body - he pointed out that this 15? was the distance of the "steps" noted by Babylonian astrologers - a point which might be relevant to how old that association is. He also observed that altogether the Sun's rays then fill one zodiac sign, and give the convenience of the Sun's influence mirroring a calendar month.

Actually, I will check for the ref - I'm no longer sure how much of that was his view, or what I might have taken from elsewhere.

OK, I doubt this will be of much use to anyone here, but just in case. This is an endnote I have in an as yet unpublished paper on the early history of orbs. It is attached to a comment I make myself, that the Sun's 15? orb is both philosophically pleasing, in giving the Sun full reign over one (monthly) division of the zodiac; and convenient, for the systematic recording of distinct synodic phases. In regard to that 15? orb of the Sun, the footnote reads:
Suzanne Denningmann writes (p.196; f.16) ?In ancient astrology the approximate value of 15? was commonly regarded as this distance. The earliest evidence for this value in Hellenistic astrology is Ps.-Eudox. ars [a 2nd century BCE papyrus] 14.7-10 p.20-21. It is already attested in Babylonian testimonies?.

Neugebauer?s comments are also of relevance (II, p.760ff.):
Theodosius determined the time of visibility of fixed stars by applying the rule that the Sun should be ? sign away from the horizon, measured on the ecliptic. It seems likely that this visibility limit, ? sign ahead or behind the Sun, is related to the old measurement of arcs by multiples and fractions of signs, a norm of which the ?steps? of 15? are a remnant? From an astronomical viewpoint a universal 15? visibility limit is a rather crude simplification of facts which obviously are much more complex. It cannot have escaped notice that not all stars appear or vanish simultaneously or that the eastern or western parts of the horizon are not the same in darkness near sunrise or sunset. Nevertheless the 15? limit ? or the equivalent 15-day limit for the solar motion ? was generally accepted.
It is interesting to compare the measure of ?? sign away from the horizon, measured on the ecliptic? with the approximation that Valens employs for finding the date when the Moon will become invisible (Valens, 1.13; p.37): ?Wherever the Sun should be found, take half the ascension of its zoidion?. His system of sign ascensions employs the relationship of signs that hear each other (which generate the contra-antiscia) and is explained at 1.6. It shows that a half measure could range from 10? either side of the Sun for the spring signs Aries and Pisces, up to 20? either side for the autumnal signs Virgo and Libra. Again, taking an average of the yearly figures results in a mean value of 15?.
In case any of that might have some relevance, the details of the sources mentioned are:
