Gemini Constellation [Stellarium]

The Sun joins Castor on July 12

Fixed star Castor, Alpha Geminorum, is a 1.9 magnitude complex multiple star system made up of six individual stars, located in the head of the Northern Twin of Gemini Constellation. Although it is designated α, it is actually fainter than β Geminorum (Pollux).

A binary star, bright white and pale white, it is situated on the head of the Northern Twin. It represents Castor, the mortal one of the twins, famous for his skill in taming and managing horses. Sometimes called Apollo, and symbolically named A Ruler yet to Come. [1]

Castor and Pollux were the Two Gods of Sparta in Greece, sons of Leda, Queen of Sparta. Their Roman equivalents are Apollo and Hercules. Pollux (Hercules) comes from the Greek Polydeuces, hence he was the Boxer. Pollux was the immortal twin and a skilled Horseman. When Castor was killed in battle, Pollux asked his father Zeus (Jupiter) that he die to forever be with Castor. Zeus killed Pollux with a bolt of lightning and placed the twins in heaven as the constellation Gemini.

Fixed Star Castor Astrology

Castor gives distinction, a keen intellect, success in law and many travels, fondness for horses, sudden fame and honor but often followed by loss of fortune and disgrace, sickness, trouble and great affliction. Its natives are said to be mischievous and prone to violence.

According to Ptolemy, it is of the nature of Mercury; to Wilson, Simmonite and Pearce, of Mars, Venus and Saturn; and, to Alvidas, of the Moon, Mars and Uranus. [1]

Fixed star Castor has a Venusian spectra and has always been considered to portend mischief and violence, but can indicate a keen mind and many travels. Venus can cause an indolent character leading an individual to his own destruction. [2]

Castor, in the Twins and together with Pollux, is called “Thiassis eyes”, a name given to these two stars by the ancient Germans. The Babylonians considered both stars as a pair belonging together, as “herdsman and warrior”. The Phoenicians recognized in the twin stars, helpers if in peril on voyages at sea.

Castor is influenced by Mercury and has a blend of Jupiter in it. Linked with the Moon and Mercury, it has the effect of such people being blessed with a good nature and fine morals. It is also supposed to convey refined manners. A conjunction with the Sun or Mars will make for energetic characteristics and a certain tendency for satire and cynicism, depending on the position of Mercury or Mars in the chart as a whole. [3]

Castor, α Gemorium, was the horseman of the twins, just as Abel was the animal keeper, and he shared Abel’s fate of being killed by his brother. Pollux got his brother drunk to make the task easier, or as one wag among classical astrologers put it: He got Castor oiled! In astrology, Castor is counted a star of misfortune, and the specific association with breaking an arm or leg may come from the Ptolemaic classification of this as a Mercury star; a planet which is much associated with the arms, or the limbs generally. Castor is also noted in natal astrology for proneness to nervous breakdowns, and the author has often found it prominent on the horoscopes of his many clients in neurotic distress.

But Castor’s Mercury quality does have a better side to it, as does all else counted ‘bad’ in this world of the heavens. People with it prominent and well aspected are exceptionally gifted intellectually, a good creative quality along with this – a bonus from the combination of intellectual Gemini Constellation and intuitive Cancer Sign. Where these potential geniuses often need help is in not letting their concern for others go ‘over the top’ beyond their own sensible state of responsibility and practical ability to help, the negative qualities of the combined Gemini-Cancer qualities.

Castor’s connection with Mercury goes deeper yet. he Greeks knew it at one time as Apollo, and, at another time, they called the planet Mercury by that name. Still earlier, Apollo was that other sun which we have since called Phaeton, which is no more. And just as that was Sun’s close companion then, so is Mercury its closest one now. And to cap that, Castor, the former Apollo, is in fact a Binary Pair of stars, as once were Sun and Phaeton. A binary pair evokes a deep-seated fear in humanity, an unconscious recall of The Disaster, so that we tend to react to it just as one does all the wrong things in a moment of crisis, if it happens to half-awaken in one some earlier trauma of the same kind. The author has experimented with acquainting ‘Castor-stricken’ clients with the true story behind our fear of binaries, and the results so far in banishing panic reactions in crises have been very heartening.

Constellation Gemini

Gemini is said to cause trouble and disgrace, sickness, loss of fortune, affliction and danger to the knees. [1]

Those born within Gemini will be crafty in the good sense of the word, in all their works and in all their tasks. Among them will be writers, mathematicians, astronomers, and famous sages. They will be truthful individuals and moderate in their fear of God. In terms of children, the Gemini are specially charged with the production of twins. Gemini was given the name “many-faced” in ancient times because it denotes not only twins, but three or more children at a single birth.

The Gemini produces a generous and chaste personality. Individuals excelling in games and fond of philosophy and astronomy are also indicative of Gemini, as are also those who are magnanimous, munificent, and (sometimes) violent. Modern astrologers attribute the following to the Gemini: clever, intuitive, restless, heartlessness, undependability, inquisitive, lack of perseverance, and sometimes too clever. Classicists say that the Geminian follow the professions of kings, calculators, teachers, hunters, dancers, musicians, painters, and tailors. The Modernists add: journalists, novelists, lecturers, linguists, commercial travelers, and pupils. [6]

Astrologers assigned to this constellation guardianship over human hands, arms, and shoulders; while Albumasar held that it portended intense devotion, genius, largeness of mind, goodness, and liberality. Considered the House of Mercury and a fortunate sign. Chinese astrologers asserted that if this constellation were invaded by Mars, war and a poor harvest would ensue. [2]

7th Arabic Manzil – Al-Dhira

Favorable for gain and friendship and for lovers, and destroys magistracies.

With Moon: Travel and take medicine.

22nd Chinese Xiù – 井 (Jǐng) Well

This is the head of the Phoenix. Associated with beauty, water, navigation at sea, hygiene, cleaning, repairs, and refurbishments. Because of the association of cleanliness with Godliness (virtue), this mansion also presides over law and order, moral uprightness and cleansing of moral wrongs.

The luck in this mansion is said to vary because of the conflict of the elements involved. Labor is rewarded, while idleness is sanctioned. It is good for taking exams, tending to herbivorous animals and all types of industriousness. It is very good for gardening and widows. Bad for funerals because of the risk of epidemics and sudden death, though, and all projects in progress should be worked on instead of being put aside.

There are no extreme problems at this point except that the energy flow to the parathyroids may cause an imbalance in the digestive fluids; that is, an imbalance of fluids at times, and at other times, a little less. This is not particularly severe. When the digestive enzymes are abundant, they can eat heavier foods. When low, they should eat lighter foods. Lettuce is excellent for this point.

11 thoughts on “Fixed Star Castor

  1. i have a stellium there of mars(16:40 degrees), venus 17:24 degrees) and jupiter (19:53 degrees) in the 12th house.

  2. Castor in Cancer is an evil star especially if it is rising in the ascendant and opposition Uranus plus some squares. I found this star prominent in “The Angel of Death” chart: Josef Mengele the SS doctor. Neptune is conjunct both Castor and Pollux both evil stars. This dreadful doctor caused the deaths of thousands if not millions. He is perhaps the worst Nazi of all of Hitler’s troops. Neptune in Cancer has at least 9 aspects so the evil nature of Neptune is especially highlighted.

  3. I wish that theres more info for Mars conjunct Castor since I have it on 0 orb, conjunct Chiron.

  4. Thanks for that again Jamie. You cannot really mean though though that one aspect in anyone’s chart paints the whole picture. However, the July 13th eclipse was opposite Pluto at 20.40 degrees. Now what did that mean for the world with the powerful Sun and Moon together ??

  5. I cannot get busy with other charts because this bothersome character always shows up just to use our yard. Castor is a evil star in square to Venus conjunct Saturn. This jerk is deceitful and withdraws from wife and children. I feel sorry for his family who appears to try to make a life without this childish useless father showing up for someone to help out. This character will use anyone acting sympathetic until he gets his claws into someone to bail him out. Not all Pisces are losers but his Sun joins Scheat who spends his life dreaming of impossibilities. His wife works yet he want them to live out in the wilderness.

    • Up yours…and around the corner

    • Vivian Robson wrote this in London in 1923. Because of the law and the influence of the Church, he wrote “evil disposition” instead of “gender diverse”. I thought it would be helpful to add (LGBT) but I guess not.
