Plato, Letters 363c

φιλαίδης παρὰ βασιλέως ἥκων τοῦ μεγάλου ἔλεγεν περὶ σοῦ· εἰ δὲ μὴ πάνυ μακρᾶς ἐπιστολῆς ἦν, ἔγραψα ἂν ἃ ἔλεγεν, νῦν δὲ Λεπτίνου πυνθάνου.ἂν τὸν θώρακα ἢ ἄλλο τι ὧν ἐπιστέλλω πέμπῃς, ἂν μὲν αὐτός τῳ βούλῃ, εἰ δὲ μή, Τηρίλλῳ δός· ἔστι δὲ τῶν ἀεὶ πλεόντων, ἡμέτερος ἐπιτήδειος καὶ τὰ ἄλλα καὶ περὶ φιλοσοφίαν χαρίεις. Τείσωνος δʼ ἔστιν κηδεστής, ὃς τότε ὅθʼ ἡμεῖς ἀπεπλέομεν ἐπολιανόμει.ἔρρωσο καὶ φιλοσόφει καὶ τοὺς ἄλλους προτρέπου τοὺς

on his arrival from the Great King, was talking about you; and if it had not required a very long letter I would have told you in writing what he said; but as it is, ask Leptines to tell you. If you are sending the corslet or any of the other things I have written about, in case you have anyone you prefer yourself, give it to him, but if not, give it to Terillus; he is one of those who are constantly making the voyage, and he is a friend of ours who is skilled in philosophy as well as in other things. He is also a son-in-law of Teison who was city-steward at the time when we sailed away. Keep well and study philosophy and exhort thereto
