Passage 8.51.3
Λακεδαιμονίων δὲ τηνικαῦτα ἐς ἔμφυλον προηγμένων στάσιν, τριακοσίους μὲν τῆς στάσεως μάλιστα αἰτίους ἐξέβαλεν ἐκ Πελοποννήσου καὶ τῶν εἱλώτων τε ἀπέδοτο ὅσον τρισχιλίους, τείχη δὲ περιεῖλε τῆς Σπάρτης καὶ τοῖς ἐφήβοις προεῖπε μὴ τὰ ἐκ τῶν νόμων τῶν Λυκούργου μελετᾶν, ἐφήβοις δὲ τοῖς Ἀχαιῶν κατὰ ταὐτὰ ἀσκεῖσθαι. καὶ τοῖς μὲν ὕστερον ἀποδώσειν ἔμελλον Ῥωμαῖοι παιδείαν τὴν ἐπιχώριον·
At that time, as the Lacedaemonians had advanced towards civil strife amongst themselves, he expelled from the Peloponnese the three hundred men most responsible for the sedition and sold off about three thousand of the helots. He destroyed the walls of Sparta and commanded the Spartan youths to cease practicing the customs established by Lycurgus, prescribing instead that they adopt the training methods of the Achaean youths. However, later the Romans were to restore the traditional education to them.
