Διόσκουροι
Castor and Pollux, the divine twins

The Dioscuri were twin brothers — Castor (mortal) and Pollux (divine) — inseparable in life, who chose to share immortality by alternating between Olympus and Hades.

The Myth

Castor and Pollux were born from Leda: Pollux was Zeus's son (divine), Castor was Tyndareus's (mortal). They sailed with the Argonauts, rescued Helen from Theseus, and were inseparable. When Castor was killed, Pollux begged Zeus to share his immortality. Zeus placed them in the sky as the constellation Gemini, alternating between Olympus and Hades. Sailors prayed to them during storms — St. Elmo's fire was their sign of protection.
