Parnassus orParnassos (Ancient Greek:Παρνασσός) was a town in the northern part ofancient Cappadocia, on the right bank of theHalys River, and on or near a hill, to which it owed its name, on the road betweenAncyra andArchelais, about 63 miles west of the latter town.[1][2] It became a bishopric and remains a Roman Catholictitular see.
Several of its bishops were historically documented :
Pancratius, anArian heretical schismatic, among the dissident bishops which left theCouncil of Sardica and held a small council atPhilippopolis (now Plovdiv Bulgaria) issuing a separate Arian position.
Ipsius and Ecditius, whomChurch Father SaintBasil the Great of Caesarea Mazaca in Cappadocia mentioned in a letter
The bishopric is mentioned in the Byzantine imperialNotitiae Episcopatuum till the late 13th century, but it faded, apparently at the advent of MuslimSeljuks.
