Castor

Castor is one of the Dioscuri, the divine twins of Greek mythology, known for his brotherhood with Polydeuces (Roman: Pollux). Renowned for his skills in horsemanship and combat, Castor represents loyalty, bravery, and the strength of fraternal bonds. Though mortal while his brother was divine, the two became inseparable in myth and ultimately shared immortality among the stars as the constellation Gemini.

Family and Relations

  • Mother: Leda, queen of Sparta
  • Father: Tyndareus (mortal)
  • Siblings: Polydeuces (son of Zeus), Helen of Sparta (later Troy), and Clytemnestra (wife of Agamemnon)
  • Consorts: Part of myths involving the Leucippides—Phoebe and Hilaeira

Key Myths and Deeds

  • Birth and Dual Nature: Leda gave birth to Castor and Polydeuces after being seduced by Zeus (in the form of a swan) and sleeping with her husband Tyndareus. As a result, Castor is mortal and Polydeuces immortal.
  • Voyage of the Argonauts: The twins joined Jason on the quest for the Golden Fleece. Castor’s skill in horse-taming and combat proved invaluable. Polydeuces’s boxing ability also protected the crew from threats like the giant Amycus.
  • The Abduction of the Leucippides: Castor and Polydeuces abducted and married Phoebe and Hilaeira, who were betrothed to their cousins Lynceus and Idas. This led to a deadly feud between the two sets of brothers.
  • Castor’s Death and Immortality: During the feud, Castor was killed by Idas. Devastated, Polydeuces asked Zeus to share his immortality with Castor. Zeus granted this, allowing the brothers to alternate between Olympus and the Underworld. Together, they were placed in the sky as the constellation Gemini.

Meaning and Etymology

The name “Castor” (Greek: Κάστωρ) may stem from ancient Indo-European roots meaning “to shine” or “to excel,” befitting his heroic stature. His Roman name remains the same, and he is frequently paired with his brother under the collective title “the Dioscuri,” meaning “sons of Zeus.”
