Passage 10.35.1
ἐς Ἄβας δὲ ἀφικέσθαι καὶ ἐς Ὑάμπολιν ἔστι μὲν καὶ ἐξ Ἐλατείας ὀρεινὴν ὁδὸν ἐν δεξιᾷ τοῦ Ἐλατέων ἄστεως, ἡ δὲ ἐπὶ Ὀποῦντα λεωφόρος ἡ ἐξ Ὀρχομενοῦ καὶ ἐς ταύτας φέρει τὰς πόλεις. ἰόντι οὖν ἐς Ὀποῦντα ἐξ Ὀρχομενοῦ καὶ ἐκτραπέντι οὐ πολὺ ἐπʼ ἀριστερὰν ὁδός ἐστιν ἡ ἐς Ἄβας. οἱ δὲ ἐν ταῖς Ἄβαις ἐς γῆν τὴν Φωκίδα ἀφικέσθαι λέγουσιν ἐξ Ἄργους καὶ τὸ ὄνομα ἀπὸ Ἄβαντος τοῦ οἰκιστοῦ λαβεῖν τὴν πόλιν, τὸν δὲ Λυγκέως τε καὶ Ὑπερμήστρας τῆς Δαναοῦ παῖδα εἶναι. Ἀπόλλωνος δὲ ἱερὰς νενομίκασιν εἶναι τὰς Ἄβας ἐκ παλαιοῦ, καὶ χρηστήριον καὶ αὐτόθι ἦν Ἀπόλλωνος.
There is a mountainous road leading to Abai and to Hyampolis from Elateia, departing from the town of Elateia on the right. The highway going to Opous from Orchomenos also provides access to these cities. Thus, on the way from Orchomenos to Opous, one need only turn off a short distance to the left to reach Abai. The inhabitants of Abai say they came into the land of Phocis from Argos and that the city's name was taken from its founder, Abas, son of Lynkeus and Hypermnestra, daughter of Danaos. From ancient times Abai has been considered sacred to Apollo, and there was once an oracle of Apollo in that place.
