From this place Hermes is called Nonacriates[6] Evander Nonacrius,[7] Atalanta Nonacria,[8] and Callisto Nonacrina virgo,[9] in the general sense of Arcadian.
It consisted of the villages Peristera, Mikros Pontias, Mesorrougi, Agia Varvara and Zarouchla, situated in the modern municipal units of Kalavryta and Akrata.
[10] Some archaeologists have suggested that the ancient city was located around the modern village of Kerpini, Kalavryta municipality.
Around Kerpini, they found an ancient temple, coins, buildings, and other signs of settlement.
