Castor (kăs'tor), and Pollux (pŏl'lux). Acts 28:11, A. V.; R. V. reads "The Twin Brothers." In heathen mythology, "Castor" and "Pollux" were the names of twin sons of Jupiter, who presided over the destinies of sailors. Hence an image representing them was often seen on the prow of ancient ships, like the figure-heads of modern days. In the case of Paul's ship, the name was Castor and Pollux.
