The little town was near the Hermus River, which is shown on its coins. Situated at elevation it commanded a view of the territories of Cyme, Phocaea, and Smyrna. Under Augustus it was already on the decline; under Tiberius it was destroyed by an earthquake;[3] and in the time of Pliny it was no longer inhabited. It was, however, rebuilt later.
One of the city's more noteworthy figures was the rhetorician Hermagoras.[4]
During the Byzantine period, most probably, it renamed to Archangelus.
In 1413 the Turks seized the fortress of Archangelus, which they called Kaiadjik, i.e., small rock; this fortress was situated on the plains of Maenomenus, now known as Menemen.
Its site is located near Görece, Asiatic Turkey.[5][6]
This see is not mentioned in the Notitiae Episcopatuum. Ramsay (Asia Minor, 108) thought the diocese of Temnus identical with that of Archangelus, which from the tenth to the thirteenth century the Notitiae Episcopatuum assigns to Smyrna.
