Orcistus, titular see in Galatia Secunda. It is only mentioned in Peutinger’s “Table”. An inscription of 331 fixes the site at Alikel Yaila, also called Alekian, in the vilayet of Angora. It was then a station at the intersection of four roads and formed part of the “ Diocese of Asia”; consequently it must have belonged to Phrygia. In 451 it was in Galatia Secunda or Salutaris, probably from the formation of that province about 386-95. The name comes from a tribe called Orci, which dwelt in the plains on the eastern frontier of Phrygia. Only three bishops are known: Domnus, at Ephesus (451); Longinus, at Chalcedon (451); and Segermas, at Constantinople (692). But the see is mentioned by the ‘“Notitiae: episcopatuum” until the thirteenth century among the suffragans of Pessinus.
