Zenonopolis (sometimes abbreviated as Zenopolis[1], in particular by the Roman Curia[2]) was a city in Isauria, originally called Rusumblada but renamed in honour of Emperor Zeno (474-491), who was born there.[3]
In the Ottoman Empire, Zenonopolis was known as Isnebol in the kaza of Ermenek and the vilayet of Adana.[4]
Zenopolis was a see of Asia Minor, suffragan of Seleucia, Trachaea in Isauria, at least since the 6th century, when it is recorded as such in the Notitia Episcopatuum of Antioch.[5] In 732 circa, the province of Isauria was joined to the Patriarchate of Constantinople, and Zenopolis appears about 940 in the Notitia Episcopatuum of Constantine Porphyrogenitus, but is situated in Pamphylia.[6] The city is again mentioned by George of Cyprus in the 7th century.[7] and by Constantine Porphyrogenitus[8] as a city of the Decapolis, presumably referring to the Isaurian Decapolis.
Le Quien[9] mentions two bishops:
Gennadius, who assisted at the Second Council of Constantinople, 553, as bishop of Zenonopolis in Pamphylia, was very probably a prelate of this see.[10]
Zenopolis remains a titular see of the Roman Catholic Church.
