Plutarch, Cato 13.5:
He mocked Postumius Albinus writing a history in Greek and asked his audience’s pardon for it, saying that it would be necessary to pardon him if he had undertaken the work compelled by the votes of the Amphictyonic League. Cato said that the Athenians marveled at the speed and the sharpness of his speech. Whatever he set forth briefly, his interpreted expanded at length and with many words. All things considered, he thought that the words of the Greeks came from their lips, but the words of the Romans came from their hearts.
Ποστούμιον γοῦν Ἀλβῖνον ἱστορίαν Ἑλληνιστὶ γράψαντα καὶ συγγνώμην αἰτούμενον ἐπέσκωψεν εἰπὼν, δοτέον εἶναι τὴν συγγνώμην, εἰ τῶν Ἀμφικτυόνων ψηφισαμένων ἀναγκασθεὶς ὑπέμεινε τὸ ἔργον, θαυμάσαι δέ φησι τοὺς Ἀθηναίους τὸ τάχος αὐτοῦ καὶ τὴν ὀξύτητα τῆς φράσεως: ἃ γὰρ αὐτὸς ἐξέφερε βραχέως, τὸν ἑρμηνέα μακρῶς καὶ διὰ πολλῶν ἀπαγγέλλειν τὸ δ᾽ ὅλον οἴεσθαι τὰ ῥήματα τοῖς μέν Ἕλλησιν ἀπὸ χειλέων, τοῖς δὲ Ῥωμαίοις ἀπὸ καρδίας φέρεσθαι.
