Stephanos of Byzantium - Ethnika
Ankyrion: a city in Italy. A citizen may be an 'Ankyrios', as in 'Byzantios', or an 'Ankyrieus', as in 'Kitieus', 'Doulichieus', 'Sigieus', and 'Sounieus'. But, owing to the custom of the region, 'Ankyrianos', as in 'Adrianos', is better—unless it should be 'Ankyrinos', just as 'Rheginos' is from Rhegion and 'Metapontinos' from Metapontion. For Italians especially favour this form.
