Easton's Bible Dictionary: M. G. Easton, M.A., D.D.
A city on the coast of Campania, on the north shore of a bay running north from the Bay of Naples, at which Paul landed on his way to Rome, from which it was distant 170 miles. Here he tarried for seven days (Acts 28:13,14
). This was the great emporium for the Alexandrian corn ships. Here Paul and his companions began their journey, by the "Appian Way," to Rome. It is now called Pozzuoli. The remains of a huge amphitheatre, and of the quay at which Paul landed, may still be seen here.
