Passage 2.15.1
Φλιασίοις μὲν δὴ τοσαῦτα λόγου μάλιστα ἦν ἄξια· ἐκ Κορίνθου δʼ ἐς Ἄργος ἐρχομένῳ Κλεωναὶ πόλις ἐστὶν οὐ μεγάλη. παῖδα δὲ εἶναι Πέλοπος Κλεώνην λέγουσιν, οἱ δὲ τῷ παρὰ Σικυῶνα ῥέοντι Ἀσωπῷ θυγατέρα ἐπὶ ταῖς ἄλλαις Κλεώνην γενέσθαι· τὸ δʼ οὖν ὄνομα ἀπὸ τοῦ ἑτέρου τούτων ἐτέθη τῇ πόλει. ἐνταῦθά ἐστιν ἱερὸν Ἀθηνᾶς, τὸ δὲ ἄγαλμα Σκύλλιδος τέχνη καὶ Διποίνου · μαθητὰς δὲ εἶναι Δαιδάλου σφᾶς, οἱ δὲ καὶ γυναῖκα ἐκ Γόρτυνος ἐθέλουσι λαβεῖν Δαίδαλον καὶ τὸν Δίποινον καὶ Σκύλλιν ἐκ τῆς γυναικός οἱ ταύτης γενέσθαι. ἐν Κλεωναῖς δὲ τοῦτό ἐστι τὸ ἱερὸν καὶ μνῆμα Εὐρύτου καὶ Κτεάτου· θεωροὺς γὰρ ἐξ Ἤλιδος ἐς τὸν ἀγῶνα ἰόντας τῶν Ἰσθμίων αὐτοὺς ἐνταῦθα Ἡρακλῆς κατετόξευσεν, ἔγκλημα ποιούμενος ὅτι οἱ πρὸς Αὐγείαν πολεμοῦντι ἀντετάχθησαν.
These were the most noteworthy matters concerning the Phliasians. On the road from Corinth towards Argos lies the city Cleonae, which is not large. They say that Cleonae was a child of Pelops; others assert that, along with his other daughters, Cleonae was born to Asopus, the river flowing by Sicyon; thus, the city received its name from one of these figures. There is here a sanctuary of Athena, and the image within it is a work of the art of Scyllis and Dipoenus. They themselves are said to have been pupils of Daedalus, though others even claim that Daedalus took a wife from Gortyn and that Dipoenus and Scyllis were born to him by this woman. At Cleonae stand this temple and also the tomb of Eurytus and Cteatus. For it was here that Heracles shot arrows and slew them, as they were journeying from Elis as sacred ambassadors to attend the Isthmian Games. He accused them of having sided against him in his war against Augeas.
