Ipsus

A titular see of Phrygia Salutaris, suffragan of Synnada. The locality was famous as the scene of the great battle fought in 301 B.C.between the successors of Alexander, in which Antigonus was slain and his kingdom divided between his rivals. As Ipsos or Hypsos the city is mentioned by Hierocles and George of Cyprus and in most of the medieval "Notitiae Epicopatuum". Le Quien (Oriens Christianus, I, 840-4I), names four of its bishops; Lucian, at the Council of Chalcedon in 451; George, at the Seventh Council in 787, Photius and Thomas at the Councils of Constantinople in 868 and 878. The city was situated at the junction of two roads, one leading to Byzantium and the other towards Sardeis; the exact site has not been discovered. Modern geographers identify it with the ruins of Ipsili-Hissar; others, like Ramsay ("Cities and Bishoprics of Phrygia", Oxford, 1897, 748), with those of Tchai, 82 miles from Apamea.
