Diocletianopolis

A titular see of Palaestina Prima. This city is mentioned by Hierocles (Synecdemus, 719, 2), Georgius Cyprius (ed. Gelzer, 1012), and in some "Notitiae Episcopatuum", as a suffragan of Caesarea. Its native name is unknown, and its site has not been identified. One bishop is known, Elisaeus, in 359 (Lequien, Oriens Christianus, III, 646). (2) Another Diocletianopolis was a suffragan see of Philippopolis in Thrace. Its site is unknown. Two bishops are mentioned, Cyriacus in 431, and Epictetus in 451 and 458. A third, Elias, in 553, is doubtful (Lequien, op. cit., I, 1161). (3) Still another Diocletianopolis was a suffragan of Ptolemais in Thebais Secunda (Parthey, Notit. Episc., I). This city also mentioned by Hierocles (op. cit., 732, 3), and by Georgius Cyprius, 772. Gelzer thinks that Diocletianopolis is a later name of Apollinopolis Minor, the Coptic Kos Bebir, and the Arabian Kûs, still existing near Keft (Coptus). (Amélineau, "Géographie de l'Egypte", 490, 573, 576) One bishop of Apollinopolis Minor is known, Pabiscus, mentioned in 431 (Lequien, II, 603).
