Gemini (Gem)
"The Twins"



Location:  R.A. = 7h, Dec. = 25 N

Mythology:  The story of the Gemini Twins has been the model for many other stories (and maybe even a few modern soap opera plots!).  The names of the two Twins are Castor and Polydeuces (more commonly known by his Roman name of Pollux).  Their mother was the queen of Sparta, Leda, but it is their father(s) that make the story interesting.  Leda was seduced by the King of the Gods Zeus when he assumed the form of Cygnus the Swan.  So her husband, King Tyndareus, would not get suspicious of her adultery, she slept with him on the same night she met with Zeus.  Leda gave birth to eggs, since Zeus had taken the form of a swan.  These eggs bore identical twins:  Castor, who was the mortal son of Tyndareus, and Polydeuces, who was the immortal son of Zeus.  Some stories also mention two daughters, Clytemnestra and the famous Helen of Troy.
    Castor and Polydeuces were inseparable.  Castor became an excellent horseman and sword fighter -- in fact, he became the teacher to Hercules; and Polydeuces became a boxer.  Both Castor and Polydeuces where on the Argo Navis with Jason and the Argonauts on the quest to find the Golden Fleece of Aries.  The Twins ended up in a brawl with another set of twins, Idas and Lynceus.  Castor was killed by Lynceus; as revenge, Polydeuces killed him.  Zeus struck Idas with one of his thunderbolts before he could move in on Polydeuces.  Because the Twins had always been inseparable and so devoted to each other, Polydeuces was filled with terrible grief at the loss of his brother.  Further, because of the way he was "born," Castor was to spend the afterlife in Hades.  Polydeuces convinced Zeus to at least let Castor spend half the year on Olympus with the other Gods.  The story goes on the further say that Polydeuces prayed so hard for his brother and to be immortal like Castor that Zeus took pity and put the brothers together in the heavens.

Other Interesting Sights:  The two brightest stars within the constellation are Castor and Pollux, the heads of the Twins.  The open cluster M35, at 2800 light years distance, is also within this constellation.
