Passage 8.19.4
λείπεται δὲ ἐκ Φενεοῦ τῶν ὁδῶν, αἵ εἰσι πρὸς ἡλίου δυσμῶν, ἡ ἐν ἀριστερᾷ. αὕτη δὲ ἡ ὁδὸς ἄγει μὲν ἐς Κλείτορα, καθήκει δὲ παρὰ τοῦ Ἡρακλέους τὸ ἔργον, ὃ τῷ ποταμῷ ῥεῦμα ἐποίησεν εἶναι τῷ Ἀροανίῳ. παρὰ τοῦτο ἡ ὁδὸς κάτεισιν ἐπὶ χωρίον Λυκουρίαν, καὶ ἔστι Φενεάταις ἡ Λυκουρία πρὸς Κλειτορίους ὅροι τῆς γῆς.
From Pheneus, among the roads which lead towards the west, the one on the left remains. This road indeed leads to Cleitor and passes by the place where Heracles performed the deed of creating a channel for the river Aroanius. From there the road descends to a place called Lykouria, and Lykouria serves as the boundary between the territory of the Pheneates and that of the Cleitorians.
