History of the star: Castor is a binary, 1.57 and 3.7, bright white and pale white, in Gemini. The mortal Twin famous for his skill in taming and managing horses, the Northern Twin (western). (The immortal Twin is Pollux the Boxer). 

Together they were "the Two Gods of Sparta", Dioscuri in Rome, Didymi, also Amphion and Zethus, Antiope's sons, who, as Homer wrote, were "Founders of Thebes, and men of mighty name". In India they Acvini, the Ashwins, or "Horsemen", they were also called Apollo (Castor) and Hercules (Pollux).

Castor was Ovid's Eques, the "Horseman of the Twins", and the mortal one as being the son of Tyndarus, in later Greek days it was Apollo [until toward the Christian era this name for the god of day was the title of the planet Mercury when morning star, - As morning and evening star in Egypt it was Set and Horus; in India, Buddha and Rauhinya; and in Greece ..."the Lovely One, and …"the Sparkling One". ].

Afelar, Aphellon, Aphellan, Apullum, Aphellar, Avellar; Avelar, Anelar, Anhelar; a title for Castor with many variations.

Caesius had the synonymous Phoebus, and also cited Theseus, but this should rather be applied to beta as another title of the original Hercules.

When the Arabians adopted the Greek figures they designated this star as Al Ras al Taum al Mukaddim, the "Head of the Foremost Twin"; but, according to Al Tizini, the early and indigenous term was Al Awwal al Dhira', the "First in the Paw" or "Forearm" referring to an enormous early Lion (Leo), the "Outstretched Forearm" of which alpha and beta marked as Al Dhira' al Mabsutat. This extended still further over Gemini, the other, the Contracted one, Al Makbudah, running into Canis Minor. The rest of this monstrosity included Cancer, part of our Leo, Bootes, Virgo, and Corvus.

As marking lunar stations; they have been identified with the Akkadian Supa, "Lustrous"; the Coptic Pimafl, the "Forearm"; the Persian Taraha, the Sogdian Ghamb, and the Khorasmian Jiray, these last three titles signifying the "Two Stars". The Egyptian Copts knew it as "the Forearm of the Nile"; from Gihon, a name for that river.

The Babylonians used Castor to mark their 11th ecliptic constellation, Mash-mashu-Mahru, the "Western One of the Twins"; while with Pollux the two constituted Mas-tab-ba-gal-gal, the "Great Twins".

In Assyria they were Mas-mas and Tuamu, the Twins. As an object of veneration Castor was Tur-us-mal-ma?, the "Son of the Supreme Temple".

They were the Hindu 5th nakshatra, Punarvarsu, "the Two Good Again"; Aditi, the sky goddess, mother of the Adityas, being the presiding divinity, and beta marking the junction with Pushya, the next nakshatra.

In astrology, everywhere, Castor has been a portent of mischief and violence.

[Star Names, Their Lore and Meaning, Richard Hinchley Allen, 1889]. 

Castor and Pollux marked the 5th Arabic Manzil (Moon Mansion) Al Dhira, The Forearm.

Influences of the 5th Manzil: Favorable for gain and friendship and for lovers, and destroys magistracies. [Influences: The district under jurisdiction of a magistrate. With Moon transiting here; travel and take medicine]. (Robson*).   

 

The astrological influences of the constellation: "Ptolemy makes the following observations; the stars in the feet of Gemini have an influence similar to that of Mercury, and moderately to that of Venus; the bright stars in the thighs are like Saturn. It is said to cause trouble and disgrace, sickness, loss of fortune, affliction and danger to the knees. By the Cabalists it is associated with the Hebrew letter Qoph and the 19th Tarot Trump, The Sun". (Robson*).

The astrological influences of the constellation given by Manilius:

"The arms to shoulders joined are accounted to the Twins" [Manilius p.119]

From the Twins come less laborious callings and a more agreeable way of life, provided by varied song and voices of harmonious tone, slender pipes, the melodies inborn in strings and the words fitted thereto : those so endowed find even work a pleasure. They would banish the arms of war, the trumpet's call, and the gloom of old age : theirs is a life of ease and unfading youth spent in the arms of love. They also discover paths to the skies, complete a survey of the heavens with numbers and measurements, and outstrip the flight of the stars: nature yields to their genius, which it serves in all things. So many are the accomplishments of which the Twins are fruitful. [Manilius, Astronomica, 1st century AD. p.281.]

 

The general astrological influences of the star: 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. It 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. (Robson*).

Associated with guile and duplicity. (Larousse Encyclopedia of Astrology).

Castor has specific associations with breaking an arm or leg and this may come from the Ptolemaic classification of Castor as a Mercury star, which is much associated with the limbs generally. Castor is also noted in natal astrology for proneness to mental breakdowns and neurotic distress. People with this star prominent and well aspected are exceptionally gifted intellectually. Where these geniuses often need help is in not letting their concern for others go 'over the top'. (The Living Stars, Dr. Eric Morse).

Castor is influenced by Mercury and has a blend of Jupiter in it. Linked with the Moon or 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. (Fixed Stars and Their Interpretation, Elsbeth Ebertin, 1923)
