Passage 4.5.2
Πολυχάρην δὲ ἐκδοῦναι μὲν ἐπὶ τιμωρίᾳ Λακεδαιμονίοις οὔ φασιν, ὅτι μηδὲ ἐκεῖνοι σφίσιν Εὔαιφνον, ἐθέλειν μέντοι παρὰ Ἀργείοις συγγενέσιν οὖσιν ἀμφοτέρων ἐν Ἀμφικτυονίᾳ διδόναι δίκας, ἐπιτρέπειν δὲ καὶ τῷ Ἀθήνῃσι δικαστηρίῳ, καλουμένῳ δὲ Ἀρείῳ πάγῳ, ὅτι δίκας τὰς φονικὰς τὸ δικαστήριον τοῦτο ἐδόκει δικάζειν ἐκ παλαιοῦ.
They say that Polychares refused to surrender himself for punishment to the Lacedaemonians, on the grounds that they likewise had not surrendered Euaiphnos to them. He declared, however, that he was willing to stand trial before the Argives, who were kinsmen of both parties, in the Amphictyonic council, or to entrust the judgment to the Athenian court known as the Areopagus, because from ancient times this court was reputed to adjudicate cases of homicide.
