Passage 8.52.4
κεκακωμένον δὲ ἤδη τὸ Ἑλληνικὸν Κόνων ὁ Τιμοθέου καὶ Ἐπαμινώνδας ἀνεκτήσατο ὁ Πολύμνιδος, ὁ μὲν ἐκ τῶν νήσων καὶ ὅσα ἐγγυτάτω θαλάσσης, Ἐπαμινώνδας δὲ ἐκ τῶν πόλεων τῶν ἀπὸ θαλάσσης ἄνω Λακεδαιμονίων τὰς φρουρὰς καὶ ἁρμοστὰς ἐκβαλόντες καὶ δεκαδαρχίας καταπαύσαντες· Ἐπαμινώνδας δὲ καὶ πόλεσιν οὐκ ἀφανέσι, Μεσσήνῃ καὶ Μεγάλῃ πόλει τῇ Ἀρκάδων, λογιμωτέραν τὴν Ἑλλάδα ἐποίησεν.
After the Greeks had already suffered devastation, Conon, the son of Timotheus, and Epaminondas, the son of Polymnis, restored their fortunes. Conon recovered the islands and those areas which lay closest to the sea, while Epaminondas reclaimed the inland cities, driving out the Spartan garrisons and harmosts and abolishing the governing councils of ten men. Moreover, Epaminondas founded notable cities—Messene and the great city of the Arcadians—and thus made Greece more illustrious.
