Stephanos of Byzantium - Ethnika
Pamphylia: a region bordering Isauria, named after Pamphyle, daughter of Rhakios and Manto. Those who inhabit it are 'Pamphylioi'. [The feminine is 'Pamphylis',] the possessive 'Pamphyliakos', just as 'Kypriakos' is from 'Kyprios', 'Boiotiakos' from 'Boiotios'. But 'Pamphylis' ought to have been accented with acute on the antepenult, like 'Agrylis', because of the length of the υ. For words that have the υ shortened are oxytone: 'pegylis', 'for an evil night came on, a pegylis, when Boreas had fallen', 'Thegylis', an epithet of Athena, 'gongylis'. But 'Pamphylis' as an ethnonym is oxytone, like 'Aiolis', 'Aitolis', and similar forms.... The tribesman is 'Pamphylos', but also 'Pamphylios'. There is also a Pamphylia, a city in Makedonia.
