Stephanos of Byzantium - Ethnika
Nakoleia: a city in Phrygia. Strabo, book 12. The name is neuter, after Nakole, a nymph. And just as 'nymphaion' is from 'nymphe' and 'Heraion' from 'Hera', so 'Nakolaion' is from 'Nakole'. The ethnonym is 'Nakolaieus'. But if the form is 'Nakoleia', with a diphthong, deriving from 'Nakolos', the son of Daskylos, the ethnonym will be 'Nakoleus', as 'Seleukeus' is from 'Seleukos'.
