Porphyrios, Vita Plotini 12 (3.-4. Jh.).

ἐτίμησαν δὲ τὸν Πλωτἴνον μάλιστα καὶ ἐσέφϑησαν Γαλιῆνός τε ὁ αὐτοκράτως καὶ ἡ τούτου γυνὴ Σαλωνίνα. Ὁ δὲ τῇ φιλίᾳ τῇ τούτων καταχρώμενος φιλοσόφων τινὰ πόλιν κατὰ τὴν Καμπανίαν γεγενῆσϑαι λεγομένην, ἄλλως δὲ κατηριπωμένην ἠξίου ἀνεγείρειν καὶ τὴν πέριξ χώραν χαρίσασϑαι οἰκισϑείσῃ τῇ πόλει, νόμοις δὲ χρῆσϑαι τοὺς κατοικεῖν μέλλοντας τοῖς Πλάτωνος καὶ τὴν προσηγορίαν αὐτῇ Πλατωνόπολιν ϑέσϑαι, ἐκεῖ τε αὐτὸς μετὰ τῶν ἑταίρων ἀναχωρήσειν ὑπισχνεῖτο.
Καὶ ἐγένετ̓ ἂν τὸ βούλημα ἐκ τοῦ ῥᾴστου τῷ βασιλεῖ φϑονοῦντες ἢ νεμεσῶντες ἢ δἰ ἄλλην τινὰ αἰτίαν μοχϑηρὰν ἐνεπόδισαν.
12. The Emperor Gallienus and his wife Salonina greatly honoured and venerated Plotinus, who thought to turn their friendly feeling to some good purpose. In Campania there had once stood, according to tradition, a City of Philosophers, a ruin now; Plotinus asked the Emperor to rebuild this city and to make over the surrounding district to the new-founded state; the population was to live under Plato's laws: the city was to be called Platonopolis; and Plotinus undertook to settle down there with his associates. He would have had his way without more ado but that opposition at court, prompted by jealousy, spite, or some such paltry motive, put an end to the plan. (Übers. S. MacKennan)
