Passage 8.30.8
Μεγαλοπολίταις δὲ ἐπὶ τῆς ἀγορᾶς ἐστιν ὄπισθεν τοῦ περιβόλου τοῦ ἀνειμένου τῷ Λυκαίῳ Διὶ ἀνὴρ ἐπειργασμένος ἐπὶ στήλῃ, Πολύβιος Λυκόρτα· γέγραπται δὲ καὶ ἐλεγεῖα ἐπʼ αὐτῷ λέγοντα ὡς ἐπὶ γῆν καὶ θάλασσαν πᾶσαν πλανηθείη, καὶ ὅτι σύμμαχος γένοιτο Ῥωμαίων καὶ παύσειεν αὐτοὺς ὀργῆς τῆς ἐς τὸ Ἑλληνικόν. συνέγραψε δὲ ὁ Πολύβιος οὗτος καὶ ἄλλα ἔργα Ῥωμαίων καὶ ὡς Καρχηδονίοις κατέστησαν ἐς πόλεμον, αἰτία τε ἥτις ἐγένετο αὐτοῦ καὶ ὡς ὀψὲ
The Megalopolitans have in their market-place, behind the enclosure sacred to Zeus Lycaeus, a statue upon a pillar, portraying Polybius, the son of Lycortas. Elegiac verses are inscribed on it, saying that he had traveled over all earth and sea, that he had become an ally of the Romans, and that he had appeased their anger towards Greece. This Polybius composed other works as well, among them an account of the deeds of the Romans, recording how war arose between them and the Carthaginians, the reason behind this conflict, and how it happened at a late stage.
