Passage 4.36.7
ἀφικομένων δὲ ἐς Κυπαρισσιὰς ἐκ Πύλου σφίσι πηγὴ ὑπὸ τῇ πόλει πλησίον θαλάσσης ἐστί· ῥυῆναι δὲ Διονύσῳ τὸ ὕδωρ λέγουσι θύρσῳ πλήξαντι ἐς τὴν γῆν, καὶ ἐπὶ τούτῳ Διονυσιάδα ὀνομάζουσι τὴν πηγήν. ἔστι δὲ καὶ Ἀπόλλωνος ἐν Κυπαρισσιαῖς ἱερὸν καὶ Ἀθηνᾶς ἐπίκλησιν Κυπαρισσίας. ἐν δὲ Αὐλῶνι καλουμένῳ ναὸς Ἀσκληπιοῦ καὶ ἄγαλμά ἐστιν Αὐλωνίου· κατὰ τοῦτο ὁ ποταμὸς ἡ Νέδα μεταξὺ τῆς τε Μεσσηνίας ἤδη καὶ τῆς Ἠλείας διέξεισιν.
Coming from Pylos to Cyparissiae, they have a fountain beneath the city near the sea. They say this water sprang forth for Dionysus when he struck the earth with his thyrsus, and for this reason they call the fountain Dionysias. At Cyparissiae there is also a sanctuary of Apollo, and one of Athena, surnamed Cyparissia. In a place called Aulon is a temple of Asclepius and a statue called Aulonius. Near this spot the river Neda flows, forming at this point the boundary between Messenia and Elis.
