The Legend of Castor

Castor was one of the Dioscuri, twin brother of Polydeuces, born to Leda of Sparta.‌​‌​‌​‍​‍​‌​‍​‍​‍​‍​‍​‌​‍​‌​‌​‍​‌​‍​‍​‌​‌​‌​‌​‌​‍​‌​‌​‍​‌​‍​‍​‌ In the common tradition, Castor was the mortal son of King Tyndareus while Polydeuces was the immortal son of Zeus, both conceived on the same night. Castor was renowned as a horse tamer and rider without equal. The twins joined the Argonauts, rescued their sister Helen from Theseus, and participated in the Calydonian Boar Hunt. During a cattle raid dispute with their cousins Idas and Lynceus, Castor was killed by Idas. Polydeuces, devastated, begged Zeus to let him share his immortality. Zeus arranged for the brothers to alternate between Olympus and Hades, spending eternity together.
