Castor and Pollux

also known as: Castor and Polydeuces, Castores, The Twin Brothers, The Two Gods, Gemini (literally “twins”), Tyndarids, Polydeuces (Latin: Pollux) — also together known as the “Dioscuri” or “Dioskouroi”

These twin half-brothers of Greek and Roman pagan mythology were worshiped by some. They were regarded as the tutelary divinities of sailors.

They appeared in the heavens as the constellation Gemini.

Mother: Leda (daughter of the Aetolian King Thestiu)

Father of Castor: Tyndareus, the king of Sparta

Father of Pollux: Zeus, who seduced Leda in the guise of a swan

Their figures were probably painted or sculptured on the prow of the Alexandrian ship which Luke refers to in Acts 28:11.
