Petinessus (Pitnisus) was a town and bishopric in the late Roman province of Galatia Secunda.
Petinessus is mentioned by Strabo;[1] Ptolemy;[2] Hierocles;[3] and Stephanus Byzantius, s. v. According to the first of these authors it was situated in the salt desert, to the west of Lake Tatta, between Lycaonia and Haimama.
[4] The exact name and position of the city, which differs greatly according to various documents, is not known.
William Mitchell Ramsay[5] mentions the place as near the site of Piri Begli or a little to the east of it.
[4] The Notitiae episcopatuum mention it among the suffragan sees of Pessinus.
