Hmmm Nearly half the signs have nothing attributed to them.

Nearly half the signs show nothing in them, but that does not mean they have nothing attributed to them...

You can read about the origins of sign rulerships, aspect theory...and all this information is valuable to astrologers no matter what "branch" of astrology they prefer. At the very least, it allows a frame work for all the speculation and new ideas that seem to crop up. Rather than dismiss something out of hand, building on the foundational logic is always better than making things up as we go along.

I always figured it was pretty clear that the Ascendant is attributed to Aries, being the 1st house and all.[/QUOTE]

Aries as the 1st house has to do with the start of the ancient calendar and the vernal equinox. If you consider the horoscope to be a calendar, Aries is the first month. That's why it corresponds to the 1st house.

Aries aka 'The Vernal Point' as the first house is related to the Tropical zodiac - which btw is neither 'right' nor 'wrong' - just simply one astrological technique of many

The Vernal Point of Tropical astrology focuses on and is based on one of the two times during a solar year when the sun crosses the celestial equator and solely from a Geocentric viewpoint reflects the relationship between the Earth and the Sun... nothing else

The device described as 'The Tropical Zodiac' was originally used by astronomers as a calendar (and not 'a Tropical zodiac') from which the first day of Spring (or Vernal Equinox) was inferred - the twelve 30[FONT=Times New Roman, serif]º[/FONT] demarcations of which thereafter were intended as simply demarcations of the twelve months of the year (and not intended to be construed as 'star signs of The Tropical zodiac'). Astrological qualities were later attributed to the twelve calendar months (tropical signs) as a result of the influence of Ptolemy.


Aries as 'first house' is simply a tropical calendrical system (referenced from the vernal point)

i.e. an astronomical coordinate system for measuring time in the solar year common at or just after the time of Hipparchus and based on Euctemon's Tropical Calendar of Seasons (432 BC)


Dr. Robert Powell's -
“History of the Zodiac” http://www.amazon.co.uk/History-Zodiac-Robert-Powell/dp/1597311529 explores the origins of the Babylonian Zodiac and its location in the ecliptic: the book reveals that the division of the ecliptic into tropical astrological signs was originally a derivation of Euctemon's tropical Calendar of Seasons (432 B.C.); "...dividing the solar year into twelve equal months commencing with the vernal equinox, in which each solar (tropical) month is named after one of each of the twelve signs..."

The Signs of Tropical Astrology are dependent for their location upon the Vernal Point which is:

(a) either of two points on the celestial sphere at which the ecliptic intersects the celestial equator.

and/or

(b) either of the two times during a year when the sun crosses the celestial equator and when the length of day and night are approximately equal; the vernal equinox or the autumnal equinox.


During the time of Claudius Ptolemaeus, Hipparchus, Valens et al when the sun crossed the celestial equator at the vernal equinox it did so at approximately 0 Sidereal Aries - thus the Vernal Point was in synch with sidereal Aries.


However, the Vernal Point is currently out of synch with sidereal Aries because the Vernal Point by its very nature reflects precession/regression so that, by the 21st Century, when the Sun crosses the equator as usual at the Spring Equinox, the Vernal Point is currently at approximately 5º sidereal Pisces and continuing to drift backwards towards Aquarius (hence the idea of 'the dawning of the Age of Aquarius')

Therefore the Vernal Point is simply symbolically 0ºAries.

When the Sun crosses the Equator at The Vernal Point at the Spring Equinox, it is no longer in Sidereal Aries but is in Sidereal Pisces. Times change. Everything is transient

astrologer Luís Ribeiro explains the astronomy & mathematics
underlying the calculation of the different forms of house division in western astrology.
- with an historical timeline
- showing when some of the different forms of house division were introduced
- who the earliest sources are that mention them
- & the time periods in which they reached the peak of their popularity.

- we go into a detailed breakdown of the astronomy and mathematics underlying

how some of the most popular forms of house division are calculated. :)
