Thycho Brahe was a Danish nobleman, astronomer, astrologer and alchimist. He is famous for his accurate and extensive stellar and planetary observations. His fascination with astronomical observation began when, as a boy, he saw an eclipse of the Sun which took place at exactly the time it was predicted. During his life’s work he measured the positions of celestial bodies every night it was possible to scry the sky, and carefully recording these measurements, year after year. His observations were some five times more accurate than the best available observations at the time. He reported also a new phenomenon on 11 November 1572: a bright star, never observed before, which had unexpectedly appeared in the constellation Cassiopeia. Since he noted that the new celestial object showed no daily parallax against the background of the fixed stars and it did not change its position relative to the fixed stars over several months he understood that it should have been a far distant star: a new star, a ‘stella nova’, called now a supernova in modern astronomy. This discovery was a milestone in breaking the aristotelian world-view which asserts the immutability and unchangeable nature of stars and celestial bodies.
The Geniture
From George Ludwig Frobenius, a german polymath versed in mathematic and astronomy who stayed with Tycho at his observatory in Hven island, we have two version of Tycho’s geniture.
The second version, which seems more accurate, reports his birth in Knutstorp on 13th December 22:47 PM, which, counting the days from noon, is 14th December 10:47.
The temperament
We firstly note that Jupiter and Venus are rising in the Tycho’s geniture. The ascendent is in Aquarius, domicile and triplicity of Saturn and bounds of Venus. Moreover Saturn is in sextile with the horoscope. The Moon in Virgo is applying to Saturn and then Mercury. Saturn is combust so he’s quite weak. So Venus and Jupiter are the Lord of Temperament and Saturn participates. Tycho’s temperament is sanguine because of Jupiter and Venus. Venus is moist and warm because she is occidental. Jupiter is occidental and he is warm. Saturn adds a melancholic tone to the mainly sanguine complexion. The conjunction of Saturn and Mercury is a sign of stutterers but Mars squares in mundo Saturn and so he loose the tongue. Lets note tha Mars is in the first house but considerebly distant from the horoscope, so he is not directly partecipant in Tycho’s temperament. Anyway Mars is still in the first house, in his domicile in Aries and in aspect with Saturn. Since Mars is out-of-sect he adds impulsivness and impetuosity to his attidute and he caused him much troubles as we will see.
Sir David Brewster writes in his book “The Martyrs of Science: The Lives of Galieo, Tycho Brahe, and Kepler”:
Tycho was a little above the middle size, and in the last years of his life he was slightly corpulent. He had reddish yellow hair and a ruddy complexion. He was of a sanguine temperament, and is said to have been sometimes irritable, and even obstinate. This failing, however, if he did posses it, was not exhibited towards his pupils or his scientific friends, who ever entertained for him the warmest affection and esteem.
The Lord of the Soul
Mercury is in Capricorn, oriental, combust. Mercury is in conjunction with Saturn at the end of Sagittarius. The Moon in Virgo, as we have already seen, is applying to Saturn and Mercury by a square. Moreover the Moon is in trine in mundo with Mercury. So Mercury and Saturn are the Lord of the Soul.
Valens says:
Saturn and Mercury are allies and productive of activities/employment. They do, however, bring slanders about religion, lawsuits, and debts, as well as disturbances about written matters and money. On the other hand, these stars make men who are not without resources and not unintelligent, with much experience and awareness, and who are curious, far-seeing scholars, seekers after mystic lore, revering the gods, but with much on their consciences.
Liber Hermetis says:
Saturn joined with Mercury makes prudent, informed, magicians knowing celestial things, knowledgeable of bad or of hidden things.
The Profession
Mercury is oriental in a diunal geniture and so is a candidate for the Lord of action. Mercury is also combust but the nearness to the Sun is not a real impediment for Mercury as it is for the other planets. The Moon in Virgo is angular and applaying to Saturn and Mercury. So Mercury is receiving the Moon. This is a further indication for Mercury to be the lord of Action.
Rhetorius the Egyptian says:
If Mercury changes to be in a good house, and expecially in a domicile of Saturn, not under the Sunbeams and expected by Jupiter, Saturn and Mars, it makes astrologer, diviner and priest.
In Tycho’s geniture Mercury is in Capricorn, a domicile of Saturn, and in conjuction with Saturn but Mercury is combust. Nevetherless the conjunction of Saturn and Mercury is an indicator of mathematicians and astronomers.
Venus is occidental but she has already the mean motion. She is with Jupiter, the Lord of the MC, both configurated with MC sicne they are at the horoscope. They for sure add fame and notoriety and success to Tycho’s actions. Even more so both Jupiter and Venus are in trine with Tyche and Tyche is with the star Arcturus.
Pezel says that, when Arcturus is in conjunction with the significators of wealth as the Lot of Fortune and the second house cusp or the Luminaries and their dispositors means incrising in wealth and very high honors.
The Duel
While at university in Germany he had a duel with a fellow student over which one was the best mathematician. He was attending a wedding party at Professor Lucas Bachmeister’s house on 10 December 1566 where everybody, including Tycho, drunk too much. He soon got in a heated argument with Manderup Parsberg, another Danish student who was his third cousin. They quarreled again on the 27th and they decided to resolve the question challenging each other to a duel. On the 29 December 1566 during the duel Tycho lost part of his nose and gained a broad scar across his forehead. In order to disguise his terrible disfigurement he wore a prosthetic nose for the rest of his life.
Mars by direction arrives at the horoscope on 24th Dicember 1566. Mars in the geniture is in Aries in the first house and out-of-sect. Since Aries signifies the head and Mars gives wounds the direction is in agreement with the event.
The profected Moon is with Mars of Nativity.
Moreover Mars in the Solar Revolution is at 24° Sagittarius and squares the Moon of Nativity at 23° of Virgo.
The Observatory
On the 23rd May 1576 a document was signed by Friederick II, the King of Denmark, in which he offered Tycho the island of Hven and funding to set up an observatory.
Saturn reaches by mundane direction the Lot of Fortune which was in the giniture in the bounds of Saturn and was in sextile and parallel in mundo with Saturn.
The death
Brahe died from a bladder infection on 24 October 1601, after etiquette kept him from excusing himself to use the bathroom during a royal banquet in October 1601 in Prague, causing his bladder to rupture.
We see that the Sun, which is the apheta, reaches by mundane direction the opposition to the natal Mars.
It’s interesting to note that Vettius Valens says that the seventh place from Daimon rules the bladder. In Tycho’s geniture in that place we found Saturn, Mercury and the Sun.
