A city in the S. of Italy, at the southern entrance of the straits of Messina, opposite Sicily; now Reggio. Here Paul (sailing from Syracuse) landed on his way to Rome and stopped a day (Acts 28:13). By curious coincidence the figures on its extant coins are the "twin brothers, Castor and Pollux," from whom Paul's ship was named. The intermediate position of Rhegium between Syracuse and Puteoli, his waiting there for a S. wind to carry the ship through the straits, the run to Puteoli within the 24 hours, all accord with geographical accuracy. The distance of Rhegium across the straits to Messina is about six miles.
