Apollonia (Α᾿πολλωνία, a frequent Greek name of cities, probably given in this case by one of the Seleucidae), a town of Palestine, between Caesarea and Joppa (Stephen of Byz.; Ptol. 5,16; Pliny, 5,14; Peut. Tab.), one of those on the sea-shore taken by the Jews under Alexander Jannaeus (Joseph. Ant. 13, 15, 4), and afterward repaired by Gabinius (Joseph. War, 1, 8, 4). It is now Arsuf, a deserted village at the mouth of the Nahr Arsuf (Irby and Mangles, Trav. p. 189; Robinson, Research. 3, 46; Chesney, Expedition, 1, 490), a place famous under the Crusaders (Wilken, Kreuzz. 2, 17, 39, 102; 4:416; 7:325, 400, 425), by whom it was confounded with Antipatris (Ritter, Erdk. 16, 590).
