Mythology of the constellation Gemini
This zodiacal constellation represents the twins Castor and Polydeuces (Pollux to the Romans).
These were born from an egg after their mother, Leda, Queen of Sparta, had been seduced by Zeus,
disguised as a swan. Although only half brothers, Castor, the mortal son of Leda's husband, King
Tyndareus, and Polydeuces, immortal son of Zeus, were extremely close and together took part in
many adventures. Sadly, on one of these Castor was killed. Polydeuces avenged Castor's murder,
but was so overcome with grief that he begged to be allowed to be with his brother in the
underworld. Zeus, knowing the strength of their feelings, and for once showing some compassion,
granted this request. He placed the twins side by side in the heavens so that they could
alternate their time together between Hades and the home of the gods.
