In the "Notitiae Episcopatuum" of Pseudo-Epiphanius (c. 640), Amorium appears as a suffragan of Pessinus, capital of Galatia Salutaris. It appears with the same rank in another of the end of the 8th century. Soon afterwards, presumably as a result of citizens of Amorium taking the imperial throne, it became a metropolitan see with, as shown by the early 10th-century "Notitiae Episcopatuum" of Leo VI the Wise, five suffragan sees: Philomelium, Claneus, Docimium, Polybotus. and Pissia. There is no longer any mention of the see in the 14th-century "Notitiae Episcopatuum".
