Parnassus or Parnassos (Ancient Greek: Παρνασσός) was a town in the northern part of ancient Cappadocia, on the right bank of the Halys River, and on or near a hill, to which it owed its name, on the road between Ancyra and Archelais, about 63 miles west of the latter town.[1][2] It became a bishopric and remains a Roman Catholic titular see.
Several of its bishops were historically documented :
Pancratius, an Arian heretical schismatic, among the dissident bishops which left the Council of Sardica and held a small council at Philippopolis (now Plovdiv Bulgaria) issuing a separate Arian position.
Ipsius and Ecditius, whom Church Father Saint Basil the Great of Caesarea Mazaca in Cappadocia mentioned in a letter
The bishopric is mentioned in the Byzantine imperial Notitiae Episcopatuum till the late 13th century, but it faded, apparently at the advent of Muslim Seljuks.
