The site was identified by Spratt and Forbes at the village of Arsa on the strength of an inscription (TAM II, 539) and of the evident survival of the ancient name. Their brief description remains the only one hitherto published. The village lies high, hardly less than 3000 ft. above the Xanthus valley; like many of the villages in the neighbourhood, it consists of scattered houses, having no shop, café, or other communal centre. Akdaǧ (Massicytus), which seems from across the river to rise in a steep continuous slope from the valley, in fact conceals a number of upland plains, often of surprising extent; Arsa is situated on one of these.
