Petinessus is mentioned by
Strabo;
Ptolemy;
Hierocles; 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. The exact name and position of the city, which differs greatly according to various documents, is not known.
William Mitchell Ramsay mentions the place as near the site of
Piri Begli or a little to the east of it. ==Bishops==
