Centuries earlier, it was reckoned as belonging to Pisidia, as by Polybius, who wrote that in 218 BC the people of Etenna "who live in the highlands of Pisidia above Side" provided 8000 hoplites to assist the Seleucid usurper Achaeus.
There is no other mention of Etenna in extant documents until the record of the participation of bishops of Etenna in the ecumenical councils of the 4th century AD and later. However, there are examples of its fine silver coinage of the 4th and 3rd centuries BC and of its bronze coins dating from the 1st century BC to the 3rd AD.
The Christian bishopric of Etenna was a suffragan of the metropolitan see of Side, the capital of the province of Pamphylia Secunda. Its bishop Troilus was at the First Council of Constantinople in 381, Eutropius at the Council of Ephesus in 431. Eudoxius at the Council of Chalcedon in 451, Ioannes at the Second Council of Nicaea in 787, and Petrus at the Photian Council of Constantinople (879).
