Plato, Letters 315d

πρεσβευόντων ὡς ἄρα σοῦ ποτε λέγοντος ἀκούσας ἐγὼ μέλλοντος τάς τε Ἑλληνίδας πόλεις ἐν Σικελίᾳ οἰκίζειν καὶ Συρακουσίους ἐπικουφίσαι, τὴν ἀρχὴν ἀντὶ τυραννίδος εἰς βασιλείαν μεταστήσαντα, ταῦτʼ ἄρα σὲ μὲν τότε διεκώλυσα, ὡς σὺ φῄς, σοῦ σφόδρα προθυμουμένου, νῦν δὲ Δίωνα διδάσκοιμι δρᾶν αὐτὰ ταῦτα, καὶ τοῖς διανοήμασιν τοῖς σοῖς τὴν

of the ambassadors at your Court, that upon one occasion I heard you speaking of your intention to occupy the Greek cities in Italy and to relieve the Syracusans by changing the government to a monarchy instead of a tyranny, and at that time (as you assert) I stopped you from doing so, although you were most eager to do it, whereas now I am urging Dion to do precisely the same thing; and thus we are robbing you of your empire by means of your own plans.
