Seleucia in Fausset's Bible Dictionary

Antioch's seaport. The Orontes passes Antioch, and falls into the sea near Seleucia, 16 miles from Antioch. Paul and Barnabas at their first missionary tour sailed from that port (Acts 13:4), and landed there on returning (Acts 14:26). Named from the great Alexander's successor, Seleucus Nicator, its founder, who died 280 B.C. The two piers of the old harbour still remain, bearing the names of Paul and Barnabas; the masonry is so good that it has been proposed to clear out and repair the harbour.
