Passage 2.26.1
κατὰ δὲ τὴν Λῆσσαν ἔχεται τῆς Ἀργείας ἡ Ἐπιδαυρίων· πρὶν δὲ ἢ κατʼ αὐτὴν γενέσθαι τὴν πόλιν, ἐπὶ τὸ ἱερὸν ἀφίξῃ τοῦ Ἀσκληπιοῦ. ταύτην τὴν χώραν οὐκ οἶδα οἵτινες πρότερον ᾤκησαν πρὶν Ἐπίδαυρον ἐλθεῖν ἐς αὐτήν· οὐ μὴν οὐδὲ τοὺς ἀπογόνους Ἐπιδαύρου πυθέσθαι παρὰ τῶν ἐπιχωρίων ἐδυνάμην. τελευταῖον δὲ πρὶν ἢ παραγενέσθαι Δωριέας ἐς Πελοπόννησον βασιλεῦσαί φασι Πιτυρέα Ἴωνος ἀπόγονον τοῦ Ξούθου. τοῦτον παραδοῦναι λέγουσιν ἀμαχεὶ τὴν γῆν Δηιφόντῃ καὶ Ἀργείοις·
Bordering upon Argolis, near Lessa, lies the territory of Epidaurus. But before reaching the city itself, you will arrive at the sanctuary of Asclepius. Concerning the earlier inhabitants of this region, prior to Epidaurus settling there, I cannot say who they were, nor was I able to hear anything from the local people about Epidaurus' descendants. They say, however, that before the arrival of the Dorians into the Peloponnese, the last king there was Pityreus, a descendant of Ion, the son of Xouthos. They add that he surrendered his land without a fight to Deiphontes and the Argives.
