They have been known as the patron saints of sailors, and were said to have been given the power to rescue sailors who were shipwrecked by the sea god Poseidon himself, who also gave them two white horses, which the twins often rode. The twins came to the crew’s rescue on a number of occasions. Polydeuces accepted the challenge and easily won. Polydeuces’ boxing skills came in handy when Amycus, a son of Poseidon who ruled Asia Minor, refused to let the Argonauts leave until one of them fought him in a boxing match.

The two were part of the Argonauts’ expedition to get the Golden Fleece. Castor was an excellent horseman and proficient at fencing – he is said to have taught Heracles himself to fence – and Polydeuces was famed for his boxing skills. Castor and Clytemnestra were fathered by Tyndareus and, unlike Zeus’ children, they were mortal.Ĭastor and Polydeuces grew up together and were very close. Leda later also became pregnant with Castor and Clytemnestra (who would later marry Agamemnon). The twins’ mother, Spartan Queen Leda, was seduced by Zeus, who visited the queen in the form of a swan, associated with the constellation Cygnus (the Swan), and she became pregnant with Polydeuces and Helen (who would become the famous Helen of Troy). The brothers were also known as the Dioscuri, which means “sons of Zeus.” In most versions of the myth, however, only Polydeuces was Zeus’ son, and Castor was the son of the mortal King Tyndareus of Sparta.
