**Planet
Longitudes in Babylonian Horoscopes**

** Astrological Origins** by Cyril Fagan was published by his
wife in 1971 after his death. In Chapter 14, “Six Babylonian
Genitures,” Fagan set out to prove that the Babylonian zodiac was
sidereal. Today we know that it’s unquestionably true that the Babylonians
used a sidereal zodiac.

Fagan had to depend on tables for his computation but today we have computer programs that can instantly calculate charts for ancient dates.

A book published in 1998, almost 30 years after Fagan’s death,
should interest every sidereal astrologer. * Babylonian Horoscopes*
by Francesca Rochberg (

Rochberg used an average correction factor, employing a program designed by P. Huber, to adjust the longitudes, which gives approximate computed values. However with today’s astrological software we can get exact positions for any zodiac and compare them to the ancient texts. I have computed the horoscopes that have degrees listed, so anyone can see at a glance how the modern Fagan-Bradley and Lahiri/Krishnamurti longitudes compare to the degrees given in the Babylonian tablets. The actual tablets are illustrated in Rochberg’s book.

From the computed positions of the planets, we realize that the Babylonian scribes didn’t have the ability to be completely precise with planetary positions. Nevertheless, the majority of the positions are remarkably close to the Lahairi/Krishnamurti and Fagan-Bradley zodiacs of today. We need to admit to ourselves the origin of our precise modern zodiacs:

1. **Fagan-Bradley:** This ayanamsa is a construct based primarily on
personal research by Cyril Fagan and Donald Bradley. Fagan based his ayanamsa
on the historical research that was available in his time. He is credited with
the discovery (from the astrological point of view) that the Babylonian zodiac
was strictly sidereal. The Fagan-Bradley ayanamsa has been enthusiastically
adopted by many western siderealists.

2. **Lahiri:** This ayanamsa is a contemporary one based on the
research of the Indian government’s Calendar Reform Committee. The
Committee Report was published in 1955. Lahiri’s ayanamsa comes the
closest to a universally accepted value in India and among western Jyotish
astrologers.

3. **Krishnamurti:** This is the personal ayanamsa of K.S.
Krishnamurti which he claims to have discovered in very precise work with
predictive timing techniques. This ayanamsa has become popular with modern
Jyotish astrologers due primarily to dasa timing and placement of planets in
divisional (varga) charts. Krishnamurti's books were published in the latter
third of the 20th century. The difference between the Lahiri and Krishnamurti
zodiacs is very small: 5 minutes 47 seconds.

There is no problem using any of these ayanamsas as long as their origins are understood, and no claims are made regarding their antiquity. As far as the the Babylonian horoscopes go, there is no evidence for a precise ayanamsa, although the scribes were amazingly accurate using methods crude by today's standards.

This horoscope (one of the more recent Babylonian charts) is interesting because it agrees with the longitudes in Babylonian star catalogues in that there is an average between the Lahiri/Krishnamurti and Fagan-Bradley degrees.

This horoscope is the most recent of the Babylonian genitures. Even the longitude of the Moon is given as computation apparently became more exact. Comparing these two dates highlights the problem with the Babylonian calculations. The Krishnamurti/Lahiri calculaitons fit better with the April 15 date, but the Sun is off by an extra degree. Scholars had to find these dates by trial and error. As astrologers we can be grateful for their work. All we have to do is plug the data into our astrological programs!
