Isionda, a titular see in the province of Pamphylia Secunda; it was a suffragan of Perge. Artemidorus, mentioned by Strabo (XII, vii, 2; XIII, iv, 15), places this city in Pisidia, and Strabo himself (XIII, iv, 17) locates it, under the name of Isinda, in the region of Termessos. Polybius (Excerpta de leg., 31), Ptolemy (V, 5), and Stephen of Byzantium call it Isionda, Isindos, Pisinda, Sinda; it is similarly referred to in the “ Notitiz episcopatuum.” Lequien (Oriens Christ., I, 1033) gives the names of five bishops who assisted at the OEcumenical Councils of Nica, Ephesus, Chalcedon, and ‘Constantinople (553), and at the Photian synod in 878. The probable location of this town, which has no history, is at Istanoz or Stanos, a nahié of the sanjak of Adalia, in the vilayet of Koniah.
