Ibora was a city in the lateRoman province ofHelenopontus, which became a Christian bishopric. It is now calledİverönü, Erbaa[1] in present-dayTokat Province,Turkey. This is stated also by theAnnuario Pontificio, which lists the bishopric as atitular see.[2]
The article by Siméon Vailhé in the 1910Catholic Encyclopedia placed its site at modernTurhal in the same modern province.[3]
Vailhé says that, according to some sources, the primitive name of the city wasGaziura, formerly a royal city, mentioned byStrabo as deserted (XII, xv:Dio Cassius, xxxv, 12). In fact aGreek inscription, which dates from the time ofMithridates VI of Pontus, has been discovered on the rock of the fortress; a subterranean gallery, hewn from the rock, descends to the interior of the mountain and served perhaps as a secret depository for the royal treasures.[3]
Ibora was the home town ofEvagrius Ponticus,[1] the famousOrigenist ascetic of the 4th century, and was situated not far from Arnesi, the property ofSaint Basil, who led a religious life on the bank of the riverIris with his friendSaint Gregory and his sisterMacrina. The correspondence of these two saints frequently mentions Ibora, which, according toProcopius (Historia Arcana, xviii), was destroyed by anearthquake in the 6th century.[3]
Le Quien (Oriens Christ., I, 533) mentions seven bishops of Ibora, from the 4th to the 9th century. The bishopric was still active about the year 1170 underManuel Comnenus (Hierocles; Parthey, "Hieroclis Synecdemus," 108).[3]
