Passage 8.52.1
καὶ ἤδη τὸ μετὰ τοῦτο ἐς ἀνδρῶν ἀγαθῶν φορὰν ἔληξεν ἡ Ἑλλάς. Μιλτιάδης μὲν γὰρ ὁ Κίμωνος τούς τε ἐς Μαραθῶνα ἀποβάντας τῶν βαρβάρων κρατήσας μάχῃ καὶ τοῦ πρόσω τὸν Μήδων ἐπισχὼν στόλον ἐγένετο εὐεργέτης πρῶτος κοινῇ τῆς Ἑλλάδος, Φιλοποίμην δὲ ὁ Κραύγιδος ἔσχατος· οἱ δὲ πρότερον Μιλτιάδου λαμπρὰ ἔργα ἀποδειξάμενοι, Κόδρος τε ὁ Μελάνθου καὶ ὁ Σπαρτιάτης Πολύδωρος καὶ Ἀριστομένης ὁ Μεσσήνιος καὶ εἰ δή τις ἄλλος, πατρίδας ἕκαστοι τὰς αὑτῶν καὶ οὐκ ἀθρόαν φανοῦνται τὴν Ἑλλάδα ὠφελήσαντες.
After this time Greece ceased to produce successive generations of truly noble men. For Miltiades, son of Cimon, who conquered in battle the barbarians that had landed at Marathon and thus held back from advancing farther the expedition of the Medes, was the first man who served as a benefactor to Greece as a whole, while Philopoemen, son of Kraugis, was the last. Others before Miltiades—such as Codrus, son of Melanthus, and the Spartan Polydorus, and Aristomenes of Messenia and perhaps a few more—each individually achieved distinguished deeds, but they benefited their own native cities and did not in any united way benefit Greece collectively.
