Passage 10.8.8
ἐν δὲ τοῦ γυμνασίου τῷ ὑπαίθρῳ πεφυκέναι ποτὲ ἀγρίαν φασὶν ὕλην, καὶ Ὀδυσσέα, ἡνίκα ὡς τὸν Αὐτόλυκον ἀφικόμενος μετὰ τοῦ Αὐτολύκου τῶν παίδων ἐθήρευε, τότε αὐτὸν τὸ τραῦμα τὸ ὑπὲρ τοῦ γόνατος ἐνταῦθα σχεῖν ὑπὸ τοῦ συός. τραπομένῳ δὲ ἐς ἀριστερὰν ἀπὸ τοῦ γυμνασίου καὶ ὑποκαταβάντι οὐ πλέον ἐμοὶ δοκεῖν ἢ τρία στάδια, ποταμός ἐστιν ὀνομαζόμενος Πλεῖστος· οὗτος ὁ Πλεῖστος ἐπὶ Κίρραν τὸ ἐπίνειον Δελφῶν καὶ τὴν ταύτῃ κάτεισι θάλασσαν.
In the open area of the gymnasium, they say there once grew wild woodland, and that here Odysseus, when he came to Autolycus and was hunting with the sons of Autolycus, received the wound above his knee inflicted by the boar. Turning left from the gymnasium and descending slightly for no more, as it seems to me, than three stades, there is a river called Pleistos. This Pleistos flows down towards Cirrha, the harbor of Delphi, and reaches the sea in that direction.
