Castor and Pollux
CASTOR AND POLLUX (kăs'têr, pŏl'ŭks, Gr. Dioskyroi, sons of Zeus). In Greek mythology they were sons of Zeus by Leda, one of his numerous mistresses. Castor was a horseman and Pollux an adept boxer. They were later put in the sky in the constellation known as “Gemini,” “the Twins,” and were considered as tutelary deities favorable to sailors, a fact that explains why the ship mentioned in Acts.28.11, in which Paul sailed, was named in their honor. St. Elmo’s fire used to be credited to Castor and Pollux.
