THERE frequently arises some uncertainty as to the precise time of birth, and some apprehensions lest it should not be accurately noted. In most cases, the actual minute of the hour, at which the birth happens, can only be ascertained by making a scientific observation, at the time, with an horoscopical astrolabe; for all other instruments, employed in ascertaining the hour, are almost fallacious, although used by many persons with much care and attention. …
It seems highly necessary to present some method by which the actually ascending degree of the zodiac may be easily ascertained, in a natural and consistent manner.
(The complete text of this chapter can be found here)
This is the beginning of the third chapter of the third book of Tetrabiblos, which gives indications for a method well known, which is called Animodar, from the Persian word “namudar“, i.e. significator, index.
With these lines under their eyes different astrologers have read in MiddleAges and Renaissance the same text in very different ways.
Most of us know quite well the standard method – so maybe we can inquire a little in the version given by Giuseppe Bezza.
For what I know there is no other English version of this method, so I think it could be useful to traditional astrologers. Anyway, for what I understand of Italian -which it is my mother tongue, but sometimes I heard some strange strangers to tell they know more than me – this is a modern method, hardly taught in any Renaissance faculty 😦
This variant of the Animodar is called “ isaritmia ”, or opening of gates of passage, because this method is grounded on the fact births are not possible in every moment of the day but just when a door between heaven and earth is opened: and this moment is when there is some agreement between the syzygy preceding the birth and the nativity, between local sphere and celestial sphere, i.e. houses and zodiacal signs: this is the natural and consistent manner Ptolemy talks about.
I can’t give any English translation of the word “ isaritmia ” but I guess it comes from the Greek words: ISOS, i.e. same and RYTHMOS, motion, proportion , because the ruler of the preceding syzygy should have a proportion with the rising or culminating angle in the geniture.
The example is taken from the article written by Bezza and Fumagalli – gossips say Marco Fumagalli is the expert with numbers 🙂 Henry Paul, l’autista di Diana , and published in Linguaggio Astrale, the journal of Italian Astrological Association CIDA.
In every case Henry Paul was Lady Diana’s chauffeur, who died with her and with Dody Al Fayed in the famous car accident in Paris.
Let’s start from Henry Paul nativity.
We shall choose Placidus houses because we need 2 hours houses in order to use this method.
1) We shall start checking the syzygy preceding his birth:
We shall consider the Light above the horizon, in this case the Sun, at 01.44 Cancer, and the planet having more dignities on this degree.
Lights cannot be used as significators, so our choice is between Venus, Mars and Jupiter.
- Venus is combust and retrograde, so it cannot be a proper ruler;
- Jupiter and Mars are both against their hairesis in the Full Moon chart but Jupiter is occidental while Mars is oriental, so Mars is in better condition;
- Mars rules both the Ascendant and the MC (by exaltation) of the birth chart and it is in his hairesis there, being a night planet in a night chart.
So the ruler of the syzygy preceding the birth is Mars.
2) We shall look for some isaritmie, right proportions for Mars in respect to MC or ASC.
In fact now we are in search of proportion of Mars (ruler of syzygy) with the rising or culminating angle in the geniture.
Let’s check isaritmie for MC.
MC is at 7.00 Capricorn, Right Ascension is 277. 64.
The whole sign of Capricorn is culminating in 32.18. In fact RA of 0° Aquarius is 302.18 while RA of 0° Capricorn is 270.00, so 302.18-270.00=32.18.
The part of Capricorn already culminated is 277.64- 270.00= 7.64.
Now we should calculate the proportion between houses and signs, considering that every house is 2 hours in Placidus system.
32.18 : 2 = 7.64 : x
x = 7.64*2/32.18= 0.47
So we shall look for an hourly distance of Mars from a cusp of 0.47.
In this case we would have an isaritmia and Mars would open a door from heaven to earth.
Mars in the nativity chart is in the 12th house. Its hourly distance from Meridian is 5.30, i.e. 5.30- 4.00=1.30 from the 12th house and 2.00-1.30=0.70 from the horoscope. There is no isaritmia – no same proportion for the given time, 1:00 a.m.
So let’s rectify a little the birth time.
Let’s try 1:24 a.m.
Now Capricorn is culminating with 12°33, RA 283.65.
As before we shall take into consideration the part of the sign already culminated, i.e. 283.65-270.00=13.65
32.18 : 2 = 13.65 : x
x = 13.65 * 2 /32.18= 0.85
Mars in this example is at 4.85 from Meridian, i.e 4.85-4.00= 0.85 from the 12th house. In this case we have the same proportion because Mars is far from the 12th cusp exactly the same quantity as the culminating sign.
So at 1:24 am in Lorient, Mars is opening a door in the heaven: the natural and consistent manner mentioned by Ptolemy, elaborated by the traditional Italian astrologer Giuseppe Bezza.
In the same way we can consider isaritmie with the Ascendant, considering the OA instead of RA.
In fact there is no just a possibility, many doors can be opened by the same planet in a few minutes in respect to the MC or the Asc, so the choice between several birth times shall be always accompanied with rectification by accidents, which is the most sure and true method.
