CASTOR and POLLUX. It is said that the vessel which carried Paul to Rome had the sign of Castor and Pollux, Ac 28:11. Castor and Pollux were sea-gods, and invoked by sailors; and even the light balls or meteors which are sometimes seen on ships, were called Castor and Pollux. An inscription in Gruter proves that seamen implored Castor and Pollux in dangers at sea. It is to be observed, that St. Luke does not mention the name, but the sign, of the ship. By the word sign, the sacred writer meant a protecting image of the deity, to whom the vessel was in some sort consecrated; as at present in Catholic countries, most of their vessels are named after some saint, St. Xavier, St. Andero, St. Dominique, &c. It appears to be certain, that the figure which gave name to the ship was at the head, and the tutelary deity was placed on the poop.
