Passage 2.26.8
μαρτυρεῖ δέ μοι καὶ τόδε ἐν Ἐπιδαύρῳ τὸν θεὸν γενέσθαι· τὰ γὰρ Ἀσκληπιεῖα εὑρίσκω τὰ ἐπιφανέστατα γεγονότα ἐξ Ἐπιδαύρου. τοῦτο μὲν γὰρ Ἀθηναῖοι, τῆς τελετῆς λέγοντες Ἀσκληπιῷ μεταδοῦναι, τὴν ἡμέραν ταύτην Ἐπιδαύρια ὀνομάζουσι καὶ θεὸν ἀπʼ ἐκείνου φασὶν Ἀσκληπιόν σφισι νομισθῆναι· τοῦτο δὲ Ἀρχίας ὁ Ἀρισταίχμου, τὸ συμβὰν σπάσμα θηρεύοντί οἱ περὶ τὸν Πίνδασον ἰαθεὶς ἐν τῇ Ἐπιδαυρίᾳ, τὸν θεὸν ἐπηγάγετο ἐς Πέργαμον.
This fact also testifies to me that the god originated in Epidaurus: for I find that the most renowned sanctuaries of Asclepius originated from Epidaurus. Firstly, the Athenians, asserting that they shared their rites with Asclepius, named this festival-day Epidauria, and say that from that place Asclepius came into worship among them as a god. Secondly, Archias, son of Aristaechmus, who while hunting near Pindasos received an accidental sprain, was healed in Epidauria and consequently introduced the god into Pergamum.
