Possibly also known as Isaura Vetus, the city was in the Anatolian countryside of what was Lycaonia in today's southern Turkey and may have been the chief town of Isauria (Ἰσαυρία) district.[3] The town was mentioned by Sozomen,[4]Ptolemy,[5] and Heirocles.[6]
About 450 Maximinus entered the town in his war with Zeno.[7]
Its location is not known, but suggestions include Siristat or Tris Maden, about 13 mi (21 km) west of Isaura, or Isaura Vetus. It must have been near Isaura Nova with which it was joined.
