Claude de Laval (2)


see :http://primarydirections.blogspot.com/2017/05/cardanos-twelve-horoscopes-3.html.

Son of Jean de Laval-Bois-Dauphin, and Renee de Saint-Mars, he was married to Claude de la Jaille, widow of Guy de Laval-Lezay, lord of Lezay, from whom he had no children. He embraced, after the death of Claude de la Jaille, the ecclesiastical state; was appointed to the archbishopric of Embrun in 1554, by King Henry II, and died before having taken possession and without having been crowned.

I. Natal chart





The chart shows an opposition between SA and the group (MA, JU); this opposition occurs in cadent houses. By the way, MO is in VIII. SU is in III (cadent). ASC SAGIT, ruler JU and MC Libra, ruler, VE. Ve can be considered in house cadent (III). JU debilitated (exile, GEM).
Aspects: mundane quadrat between SU and (MA, JU).

So, it appears that MO and SU can't be HYLEG. Morinus gives however SU for ALMUTEN and it is, I think, because SU is in ARIES (exalt). We have uniquely VE as ALCHOCODEN (PTO) or SA with Omar or Bonatti. The HYLEG is SU according to PTO or SA according to the others...



quadr MO tri ME opp MA opp JU
SA 43,50 -5,54 0,00 -1,25 -1,00

D = 35.7 Y (39) - HYL MO, ALCH SA -

According to the late authors, if we take SA as ALCHOCODEN, we find 35.7 years (Claude De Lavail is dead at 39 years). But I wish to repeat here the doubts that I have in respect to this method which seems to me much too mechanical. It at least has the merit of having a detailed examination of the structure of the chart. Taking HYLEG with MO in VIII seems suspicious... It should also be noted that the zodiacal aspects do not correspond to mundane aspects and that to speak of zodiacal quadrat where there is a mundane TRI is an aberration ...

GALEAZZO SFORZA

HIERONYMI CARDANI - DE EXEMPLIS CENTUM GENITURARUM


XLIV

[[Junctinus, 428b ; Cardano 482 ; Garcaeus 383b]

GALEAZ SFORCIAE (1444-1476)




1)- introduction


Horoscopes could also be found in miscellaneous manuscripts, and much more rarely, they could constitute the core of a single manuscript containing a detailed interpretation. This is the case of Ms Trivulzianus 1329, a beautifully illuminated presentation copy of a indicium, namely a lengthy interpretation ofGaleazzo Maria Sforza’s own geniture. With its sixty-three folios, this parchment manuscript is possibly the single lengthiest astrological interpretation of a fifteenth-century horoscope still preserved. It is certainly one of the most remarkable examples of the fine intricacies and the sheer complexity of Renaissance astrology. Like many other prominent rulers of this time, Galeazzo Maria Morza had his own natal horoscope cast by an astrologer looking for permanent employment. Its author was the physician-astrologer Raffaele Vimercati, who probably studied medicine and astrology at the local university of Pavia. The work was composed sometime before the summer of 1461. The text contained a wealth of information that was deemed relevant to the life of the young duke and could help him foresee and prevent future difficulties and dangers, both personal and political.



Raffaele Vimercati donating his iudicium to Francesco Sforza, first duke of Milan. In MS Triv. 1329, Liber ludiciorum in Nativitate Comitis GaleazMarie Vicecomitis Lugurum futuri ducis. 1461, fol. 2r.

Writing such a lengthy iudicium was no trivial matter. It required a high level of competence in astronomical computation and astrological interpretation, and it would take days to be produced. The first step in casting a geniture was to produce an accurate chart (Fig. 3). Vimercati did this admirably, going through a series of very intricate calculations in order to rectify the chart and obtain the most accurate celestial figure. He did so by applying the Arabic theory of animodar, a complex series of calculations to gain higher precision as to the time of birth. Aware that an incorrect chart would lead to erroneous or questionable interpretations, he took pains to provide accurate calculations. [The Politics of Prognostication: Astrology, Political Conspiracy and Murder in Fifteenth-Century Milan, Monica Azzolini, pp. 10-13, excerpts, in History of Universities: Volume XXIII/2, Mordechai Feingold 2008]

Garcaeus, center of Sforzia genitura, Astrologiae methodus, 383


There were three principal assassins involved in Sforza's death: Carlo Visconti, Gerolamo Olgiati and Giovanni Andrea Lampugnani, all fairly high-ranking officials at the Milanese court.
Lampugnani, descended from Milanese nobility, is recognized as the leader of the conspiracy. His motives were based primarily on a land dispute, in which Galeazzo had failed to intervene in a matter which saw the Lampugnani family lose considerable properties. Visconti and Olgiati also bore the duke enmity - Olgiati was a Republican idealist, whereas Visconti believed Sforza to have taken his sister's virginity.
After carefully studying Sforza's movements, the conspirators made their move on the day after Christmas, 1476, the official day of Santo Stefano, the namesake of the church where the deed was to be committed. Supported by about thirty friends, the three men waited in the church for the duke to arrive for mass. When Galeazzo Sforza arrived, Lampugnani knelt before him; after some words were exchanged, Lampugnani rose suddenly and stabbed Sforza in the groin and breast. Olgiati and Visconti soon joined in, as did a servant of Lampugnani's.
Sforza was dead within a matter of seconds. All the assassins quickly escaped in the ensuing mayhem save for Lampugnani, who became entangled in some of the church's cloth and was killed by a guard. His body soon fell into the hands of a mob, which dragged the corpse through the streets, slashing and beating at it; finally, they hung the body upside-down outside Lampugnani's house. The beheaded corpse was cut down the next day and, in an act of symbolism, the "sinning" right hand was removed, burnt and put on display.


2)- natal chart




Unlike Vicomercati, I did not correct the time of birth and I took that given by Garcaeus, 3:15, which corresponds approximately to that indicated by Cardano (9h 10 horologia).

  • ASC SAGIT, ruler JU (VII, exil) - MO (I)
  • MC  SCORPIO, ruler MA  (IX)

- HYLEG : MO
- ALCOCODEN : VE (sextil ASC, MO)
- ANAERETA : SA, MA

Morinus gaves JU as ALMUTEN... It seems that both SU and JU are detrimental. And we have a conjunction SU-VE. We have also an opposition MO-JU and a quadrat MA-JU.

3)- primary directions



 We see 3 directions : #MO conj SA ; SA conj #MO and #MA conj VE. So, at the time of the assassination, three prominent directions were in orb: they involved both hyleg and alcocoden.

a)- #MO conj SA 


1 Regio-Campa.

b)- SA conj #MO




2 directions Placidus and Regio for this ray.

c)- #MA conj VE



We find 2 Regio-Campa and 3 Placidus directions.

conclusion


The length of life could be calculated from the natal horoscope following a complex series of calculations and manipulations. This practice conformed to a specialized technique called prorogation, which had been codified by Ptolemy in classical antiquity and further developed by Arabic astrologers in the Middle Ages. In Tetrabiblos III. 10, Ptolemy had likened the lifespan of man to an arc of the celestial ecliptic. The arc would start at a particular point on the ecliptic, the hyleg (the planet or point considered to be the ‘giver of life’ in the chart). From there the life would be cast forward with a greater or lesser force, depending on the strength of the alchochoden (the planet that was deemed to be ‘the giver of the years’). This trajectory could be arrested or reduced in length by encountering one or more destructive points or planets met in its trajectory. All these factors, considered together, would determine the actual lifespan of a person. Having established that Jupiter, the alchochoden in Galeazzo’s chart, was in a particularly favourable position, Vimercati concluded optimistically that, ‘unless the misfortunes of the hyleg make them shorter’, the duke of Milan would live eighty-one years and eleven months. [The Politics of Prognostication: Astrology, Political Conspiracy and Murder in Fifteenth-Century Milan, Monica Azzolini, pp. 13-14, excerpts, in History of Universities: Volume XXIII/2, Mordechai Feingold 2008]

We have seen that the alcocoden could not be judged by his celestial state (exile). Only VE (contracting a * with AS, MO) can claim this state.

GALEAZZO CAPRA

HIERONYMI CARDANI - DE EXEMPLIS CENTUM GENITURARUM


XXI

[[Junctinus462b, Cardano XXI 473, Garcaeus 159b ]



GALEAZZO CAPRA ((1487–1537), also known as Capella and Cappella,)


1)- introduction


was an Italian author and diplomat.
Born to a wealthy, but not aristocratic, family in Milan, Capra received a thorough humanist education. Sometime after 1522, he was appointed secretary to the chancellor and ducal legate, Girolamo Morone. He was later sent to Venice as ambassador by Francesco II Sforza, Duke of Milan. According to G. Ghilini, after Sforza’s death in 1535, Capra also occasionally served as the ambassador for Charles V, Holy Roman Emperor.
In 1525, he published the short book Della eccellenza e dignità delle donne [On the Excellence and Dignity of Women] which defends women against the calumnies of poets and philosophers. Della eccellenza was included in its entirety in the second book of his dialogue Antropologia, published in 1533. This work is divided into three books: the first examines the virtues of men, and the third considers the flaws of both genders. The Antropologia was highly praised by a contemporary historian and friend of Capra, Benedetto Giovio (1471–1545). Capra’s most famous work is the Commentarii Galeacii Capellae de rebus gestis pro restitutione Francisi Sfortiae II, ab ipsomet authore postremo recogniti [Commentaries of Galeazzo Capella on the events carried out for the restitution of Francesco Sforza II, recollected by the author himself after the events]. This work was quickly translated into Spanish, German, and Italian. It was also widely cited by Italian historian and political writer Francesco Guicciardini in his Storia d’Italia (1537–1540).
Capra died in 1537 in Milan.

HIERONYMI CARDANI

HIERONYMI CARDANI - DE EXEMPLIS CENTUM GENITURARUM


XIX

[Cardano, XIX, 468]

HIERONYMI CARDANI (1501-1576)


see Cardano

1)- introduction


Gerolamo (or Girolamo, or Geronimo) Cardano (24 September 1501 – 21 September 1576) was an Italian polymath, whose interests and proficiencies ranged from being a mathematician, physician, biologist, physicist, chemist, astrologer, astronomer, philosopher, writer, and gambler. He was one of the most influential mathematicians of the Renaissance, and was one of the key figures in the foundation of probability and the earliest introducer of the binomial coefficients and the binomial theorem in the western world. He wrote more than 200 works on science.
Cardano partially invented and described several mechanical devices including the combination lock, the gimbal consisting of three concentric rings allowing a supported compass or gyroscope to rotate freely, and the Cardan shaft with universal joints, which allows the transmission of rotary motion at various angles and is used in vehicles to this day. He made significant contributions to hypocycloids, published in De proportionibus, in 1570. The generating circles of these hypocycloids were later named Cardano circles or cardanic circles and were used for the construction of the first high-speed printing presses.
Today, he is well known for his achievements in algebra. He made the first systematic use of negative numbers, published with attribution the solutions of other mathematicians for the cubic and quartic equations, and acknowledged the existence of imaginary numbers.

Four months before his death Cardano completed his autobiography, which he had anxiously written during the entire previous year and which was supposed to sum up his complex life. He felt death approaching. According to some reports, his personal horoscope associated his end with his seventy-fifth birthday. He died on September 21, 1575, a few days before his birthday. There is a version that he committed suicide in anticipation of his inevitable death or even to confirm the horoscope. In any case, Cardano the astrologist took his horoscope seriously. In his book he described waiting for death at âge forty-four, as his earlier horoscope had foretold.



Cardano worried about whether his life had been successful. On the one hand, he lived on a meager papal pension in Rome, in enforced exile from the cities where he had spent the best part of his life, he had recently been in prison, and he was unhappy with his children. On the other hand, Cardano was sure of his own significance. He criticized much from his past, although it is not hard to discover the places where he succeeded in convincing himself that he was right. Cardano's leading idea is the predestination of his life. This is the source of his detailed analysis of the influence of the stars, his association with a "guardian angel," the scrupulous account of signs and omens, and the little events that allowed him to build a logically constructed picture of life. In a certain sense, Cardano's aim was, using the scholar's and astrologer's art, to analyze himself in detail as an object of the action of higher powers. A new style was established in science, where conclusions are drawn from the facts as they appear. Therefore, Cardano supplies the reader with detailed information about his physical features, drinking patterns, habits, etc. [Tales of Mathematicians and Physicists, Simon Gindikin, Springer, 2007, p. 21]

2)- natal chart



  • ASC TAURUS, ruler VE (VI) LIBRA
  • MC CApri, ruler SA (I)
  • MA (I), JU (XII) angular ASC
Morinus gives JU as ALMUTEN (VE near before) - MO#MA (ASC) - SU is detrimental.

3)- primary directions


a)- SU opp MC




I have already said that this direction is found in the cases of brutal death. We know the legend that some have peddled: Cardano would have committed suicide to make the date of his death coincide with the one he had calculated ...

b)- #MO conj MA



 It is a typical converse direction. 



We count 2 DP (primary directions) and 1 symbolic direction.


c)- SA # SU


Another typical converse direction ; we see that kind of direction often linked with life end and illness. This time, #SA is in conjunction with MC ; so we already have this aspect in ray : SU opp MC.


It is interesting to plot the rays versus  the standard key of ptolemy (PTO) :

 
In this diagram, 6 (line) indicates the pitch of PTO (1 ° = 1an) - on the right, the upper values, on the lower left. So, PTO = 0 in this scale.

FRANCESCO CANONA

HIERONYMI CARDANI - DE EXEMPLIS CENTUM GENITURARUM


XVII

[Cardano, 467 - Junctinus, 605a - Gauricus 79v]

 Francesco Canova da Milano (Francesco da Milano, also known as Il divino, Francesco da Parigi, etc. 1497-1543)








1)- introduction


Francesco Canova da Milano (Francesco da Milano, also known as Il divino, Francesco da Parigi, etc.) (18 August 1497 – 2 January 1543) was an Italian lutenist and composer. He was born in Monza, near Milan, and worked for the papal court for almost all of his career. Francesco was heralded throughout Europe as the foremost lute composer of his time. More of his music is preserved than of any other lutenist of the period, and his work continued to influence composers for more than a century after his death.

He died in an inaccurate location on 15 April. 1543, as attested by Gaurico while an inscription from Father Benedetto in S. Maria della Scala of Milan, reproduced by Forcella and cited by the Markets, dates back to 1544. The true name of this composer is, by scholars, conflicting news. Remembered - in the most important musical repertoire - as "Francesco da Milano", is indicated by Fétis, by Eitner (who even speaks erroneously of two musicians: "Francesco da Milano" and "Franciscus de Canona"), La Laurencie and other authors as descendants of the Milanese family of Navizziani; while Vatielli and Schmidl - referring to the book of expenses and records of Francis I - reported the surname "Canonne", which was then modified by Dorez in that of "de Canona" and "de Canonna". In fact, the only reliable data in this regard are those that can be derived from some inscriptions from Forcella, some of the pieces included in the works of the mathematician and cardan astrologer and Gaurico's papal astrologer, and - in particular - by documents at the Vatican Archive: among them, above all, a short post sent by Paul III to the Pontifical Pontifical Commissar of Salsomaggiore on 11 November. 1539 ("... tamen volentes dilecto filio Benedict Canova laic mediolanensi ...", arch. Segr. Vat., Arm. XLI, 12, 29, 46).

2)- natal chart


(august 27 1497, Gregorian)

The theme was set for 12:50, since Junctinus, in whom I often trust, says ASC 2 ° SAGIT.

  • ASC SAGIT, ruler JU (I)
  • MC VIRGO, ruler ME (IX)


Morinus gives no determined almuten... and i don't find alcocoden.

- HYLEG : JU
- ANAERETE : MA, SA (note that each anaerete is in the zodicacal house of the other).

SA is detrimental





3)- Primary directions



a)- MA conj JU




 We work now with scores of primary direction which are another modus of weighting. Actually, we have for the group of primary directions 0.175 instead of 0.04 for fictitious d group.

2)- SU opp MA


There are roughly twice as many rays of directions in the primary group as in the fictitious group.

3)- #SA conj SU



#SA is a zodicacal counter-parallel (16° LIBRA).








The results here are equivalent.

4)- SA opp ASC




We find D = 45.74°.

COCLITIS CHIROMANTIC

HIERONYMI CARDANI - DE EXEMPLIS CENTUM GENITURARUM


XVIII



  COCLITIS CHIROMANTIS (1467-1504)

1)- introduction

OF ROCCA, Bartholomew, called Cocles. - He was born, as he states, in Bologna on 19 March 1467.
The poor biographical news on D. are mainly contained in his main work, Chyromantie ac physionomie Anastasis, in which he provides some details about his short existence. In D. Proemio's work D. remembers the place and date of birth and later (book III, chapter 251) says he was an illegitimate son (some claim that his mother was a famous midwife of Bologna) who lived always poor (ibid., chapter 183), and as a boy did the barber (ibid., chapter 208). D. was known among his contemporaries, above all with the Latin nickname Cocles, which could mean "without an eye" (but this lack is not documented), both 'grim and crude of character and appearance': this second meaning of the term seems the right one, even on the basis of the testimonies of a few authors behind the Cocles, like Cardano. The name Cocles also printed all his works.
Since he was young, D. has shown a great deal for occult sciences, and at first his focus was on magical practices and the reading of books of necromancy and alchemy. However, soon after the lack of scientific foundation of these disciplines, D. turned to the study of medicine and surgery at the University of Bologna, where he graduated in 1489.
However, D.'s fame is not related to his profession of physician, but to the studies of chiromanzia and physiognomy to which he devoted himself with growing passion, especially after his encounter with the Aristotelian philosopher Alessandro Achillini, who had founded at the Studio bolognese a philosophical-naturalist school. The D. became part of the circle of the disciples of the Achilles, to whom he was deeply adored and with whom he shared the interest in occult sciences. Following the study and practice of these subjects, D. began to perform many vices and predictions with the aim of showing that through the scientific study of human characters it was possible to identify the fate of each one on a concrete basis, astrology operating instead on an abstract field.
Some predictions made by D. and timely occur, made him a big fame among his contemporaries. They began addressing him illustrious figures such as Galeazzo Sforza, brother of the Duke of Pesaro, and soon D. was invited to visit many cities of Romagna, called by their respective rulers, to preach their future. In a letter from Orazio Bicardi di Fano written to Alessandro Bentivoglio on 15 December. 1503 - which is another valuable source for rebuilding D.'s life - is said to have left his country house near Bologna, he first went to Imola, where he predicted the master of that city the end of his rule, then in Faenza, where he had a sad event for Astorgio di Faenza, who died shortly afterwards. From there he went to Rimini, Cesena and Pesaro and met also with the Duke of Urbino Guidubaldo. Also to Giulio Varano, Lord of Camerino, and his sons, he predicted a fateful destiny. But the fame of a prophet of misfortune prompted D. to drive him out of all the courts visited, forcing him soon to return home. In Bologna, for D. he began a period of tranquility, in which he could devote himself to the writing of his text on the physiognomy and coincidence, which began in about 1500 and which saw him engaged until June 28, 1504. On 4th of August, 1504 the work was printed at GA Benedetti in Bologna with the title of Chyromantie ac physionomie Anastasis, cum approbatione magistri A. Achillini. During this period D. also had the task of the Studio di Bologna to teach grammar, academic year 1503-04, to four "poor shameful" cities, without any remuneration, according to custom.
Twenty days after the publication of his work, on the 24th of September, 1504, D. died, in Bologna, assassinated almost certainly by the hand of an Antonio Caponi.

It is also very interesting to see the antiscion.


Due to the accidental disposition of the planets, one notices a rather surprising configuration : ME, VE and SU, SA are covered by their antiscion mirroring images :

PARALLELES. There are two kinds of parallels : zodiacal and mundane. Zodiacal parallels are circles équidistant from the equator, namely, the beginning of ARIES and LIBRA, and consequently any two points of the zodiac haying equal déclination, whether of the same or the opposite kind are in zodiacal parallel with each other. Thus, a star in 2° of another in 28° degrees of CAPRI, anotber. in 2° of GEMINI and another in 28° of CANCER, would all be in zodiacal parallel to each other, because they would all have the same declination in the number of degrees and minutes, viz. 20° 38'. The two first are called antiscions, because they have the same declination in number and name, viz. 20° 38' south declination ; the others are also antiscions in the same way, as having 20° 38' north declination, but the two former are called contra antiscions to the two latter, because, although their declination is the same in number, it is different in name, one being north and the other south declination. Those having north declination are called commanding, and the Southern, obeying : because the north being nearer our zenith must be most powerful. An antiscion is held by some to have the effect ot a * or v and a contra antiscion that of a □ or o-o, but Placidus makes no such distinction. [A Complete Dictionary of Astrology, in which every technical ... term ... Par James WILSON, London, 1819]

Note particularly the superposition  of ME and VE.

HALI RODOAN

HIERONYMI CARDANI - DE EXEMPLIS CENTUM GENITURARUM


XV

  HALI RODOAN (988-1061)

1)- introduction

Abu 'l Hasan Ali ibn Ridwan Al-Misri (c.998-c.1067-68) was an Egyptian physician, astrologer and astronomer. He was an astronomer, physician and commentator on Greek medicine, and in particular on Galen. Some of his commentaries on Galen's works, such as the Ars Parva, were translated into Latin by Gherard of Cremona. He is also known for his supernova observation from 1006, which he mentioned in a commentary work he composed on Ptolemy's Tetrabiblos. He was later cited by European authors as Haly, or Haly Abenrudian. He is also known through the bitter and celebrated polemic he engaged against another physician, Ibn Butlan of Baghdad.
Besides his commentary on Ptolemy's Tetrabiblos, to which we will turn on later in this article, we can mention among his works the Latin translation De revolutionibus nativitatum (The Revolutions of Nativities), edited by Luca Gaurico, printed in Venice (1524), and his Tractatus de cometarum significationibus per xii signa zodiaci (Treatise on the Significations of Comets in the twelve Signs of the Zodiac), printed in Nürnberg in 1563.




Ibn Ridwan tells us in his autobiography, which he composed when he was about sixty years old, that the astrological signs at his birth had indicated that medicine should be his profession. When I reached my sixth year I began to learn, and when I was ten years old I moved to the capital and urged on my studies. After having completed fourteen years, I began to study medicine and philosophy. I had no fortune with which I could have paid for my education, so that my education was
hampered by obstacles and difficulties. Sometimes I earned my livelihood by practicing astrology,  again by medical practice, and yet again by giving lessons. So I continued most earnestly my scientific studies until my thirtysecond year. [Medieval Islamic Treatrise, Ibn Ridwan's Tretrise, on the prevention of bodilly ills in Egypt, p. 55, University of California Press, 1984]


(1) lbn Abi U saybi'ah, 'Uyun, 2 :99; the nativity oflbn Ridwan is given in detail. Ibn Abi U saybi'ah
copied a substantial portion of Ibn Ridwan's autobiography in his work (pp. 99- 106).





This horoscope is part of Cardano's chimeras. Nevertheless, the same is found in Junctinus [543a]. It seemed useful to include it in spite of the probably fanciful date that is given. Thanks to Morinus, I was able to reconstruct the horoscope of Ibn Ridwan, on the 22nd of the month of Raamdan 377, January 20, 988 (Gregorian).

As we see, there is a triple conjunction between SA, JU and VE and the MC. 

It seems that Ibn Ridwan died in 1061, and for some in 1067, that is very old for the time. According to Ibn Abi Usaybi'ah, Ibn Ridwan died in 453/1061 or, according to Ibn al-Qifti, in the sixties of the fifth century. Modern scholarship places his death in 460/1067-68
  • ASC ARIEs, ruler MA (XII)
  • MC CAPRI, ruler SA (X) - JU SAGIT (ruler) 
We already observe that the natal chart seems very well structured, with a very strong foundation at the MC.
