Passage 2.32.2
τούτου δὲ ἐντὸς τοῦ περιβόλου ναός ἐστιν Ἀπόλλωνος Ἐπιβατηρίου, Διομήδους ἀνάθημα ἐκφυγόντος τὸν χειμῶνα ὃς τοῖς Ἕλλησιν ἐπεγένετο ἀπὸ Ἰλίου κομιζομένοις· καὶ τὸν ἀγῶνα τῶν Πυθίων Διομήδην πρῶτον θεῖναί φασι τῷ Ἀπόλλωνι. ἐς δὲ τὴν Δαμίαν καὶ Αὐξησίαν---καὶ γὰρ Τροιζηνίοις μέτεστιν αὐτῶν---οὐ τὸν αὐτὸν λέγουσιν ὃν Ἐπιδαύριοι καὶ Αἰγινῆται λόγον, ἀλλὰ ἀφικέσθαι παρθένους ἐκ Κρήτης· στασιασάντων δὲ ὁμοίως τῶν ἐν τῇ πόλει ἁπάντων καὶ ταύτας φασὶν ὑπὸ τῶν ἀντιστασιωτῶν καταλευσθῆναι, καὶ ἑορτὴν ἄγουσί σφισι Λιθοβόλια ὀνομάζοντες.
Within this enclosure is a temple of Apollo Epibaterios, an offering dedicated by Diomedes who escaped the storm that afflicted the Greeks on their return journey from Ilium. It is said that Diomedes was also the first to institute the contest of the Pythian games in honor of Apollo. Regarding Damia and Auxesia—for the Troezenians also share in their worship— they do not relate the same tradition told by the Epidaurians and Aeginetans. Rather, they say that these maidens arrived from Crete, and when the populace of the city fell into factional disputes, the maidens were stoned to death by their opponents. In memory of this event they hold a festival named Lithobolia ("the Stoning").
