Passage 2.24.2
τοῦ Δειραδιώτου δὲ Ἀπόλλωνος ἔχεται μὲν ἱερὸν Ἀθηνᾶς Ὀξυδερκοῦς καλουμένης, Διομήδους ἀνάθημα, ὅτι οἱ μαχομένῳ ποτὲ ἐν Ἰλίῳ τὴν ἀχλὺν ἀφεῖλεν ἡ θεὸς ἀπὸ τῶν ὀφθαλμῶν· ἔχεται δὲ τὸ στάδιον, ἐν ᾧ τὸν ἀγῶνα τῷ Νεμείῳ Διὶ καὶ τὰ Ἡραῖα ἄγουσιν. ἐς δὲ τὴν ἀκρόπολιν ἰοῦσίν ἐστιν ἐν ἀριστερᾷ τῆς ὁδοῦ τῶν Αἰγύπτου παίδων καὶ ταύτῃ μνῆμα. χωρὶς μὲν γὰρ ἀπὸ τῶν σωμάτων ἐνταῦθα αἱ κεφαλαί, χωρὶς δὲ ἐν Λέρνῃ σώματα τὰ λοιπά· ἐν Λέρνῃ γὰρ καὶ ὁ φόνος ἐξειργάσθη τῶν νεανίσκων, ἀποθανόντων δὲ ἀποτέμνουσιν αἱ γυναῖκες τὰς κεφαλὰς ἀπόδειξιν πρὸς τὸν πατέρα ὧν ἐτόλμησαν.
Next to the sanctuary of Apollo Deiradiotes stands a shrine to Athena, called Oxyderkes ("Keen-sighted"), dedicated by Diomedes, because once, when he was fighting at Troy, the goddess removed the mist from his eyes. Near it lies the stadium, in which they celebrate both the contest held in honor of Zeus Nemeios and the Heraia festival. On the left of the road leading up to the Acropolis, there is also a grave of the children of Aigyptos. The heads alone lie buried here separate from the bodies, while the rest of the bodies are in Lerna. For it was in Lerna that the youths were murdered, and after their deaths, the women cut off the heads and brought them as proof to their father of the deeds they had dared to commit.
