Passage 8.30.9
οὐκ ἄνευ κινδύνων μεγάλων Ῥωμαῖοι Σκιπίωνι ὅν τινα Καρχηδονιακὸν ὀνομάζουσι τέλος τε ἐπιθέντα τῷ πολέμῳ καὶ τὴν Καρχηδόνα καταβαλόντα ἐς ἔδαφος. ὅσα μὲν δὴ Πολυβίῳ παραινοῦντι ὁ Ῥωμαῖος ἐπείθετο, ἐς ὀρθὸν ἐχώρησεν αὐτῷ· ἃ δὲ οὐκ ἠκροᾶτο διδάσκοντος, γενέσθαι οἱ λέγουσιν ἁμαρτήματα. Ἑλλήνων δὲ ὁπόσαι πόλεις ἐς τὸ Ἀχαϊκὸν συνετέλουν, παρὰ Ῥωμαίων εὕραντο αὗται Πολύβιόν σφισι πολιτείας τε καταστήσασθαι καὶ νόμους θεῖναι. τῆς δʼ εἰκόνος τοῦ Πολυβίου τὸ βουλευτήριόν ἐστιν ἐν ἀριστερᾷ.
Not without great dangers did the Romans bring the Carthaginian war to an end through that Scipio whom they call "Africanus," and reduce Carthage entirely to the ground. Whenever the Roman followed Polybius' advice, his actions turned out successfully; but, whenever he failed to heed Polybius' guidance, it is said he committed errors. As for all the Greek cities that belonged to the Achaean League, these obtained permission from the Romans for Polybius himself to organize their constitutions and establish laws. The council-chamber, with Polybius' statue, stands on the left.
