Plato, Laws 683a

κατοίκισιν αὐτήν, ἣν ὑμεῖς ὀρθῶς ἔφατε κατοικεῖσθαι καὶ Κρήτην ὡς ἀδελφοῖς νόμοις. νῦν οὖν δὴ τοσόνδε πλεονεκτοῦμεν τῇ πλάνῃ τοῦ λόγου, διὰ πολιτειῶν τινων καὶ κατοικισμῶν διεξελθόντες· ἐθεασάμεθα πρώτην τε καὶ δευτέραν καὶ τρίτην πόλιν, ἀλλήλων, ὡς οἰόμεθα, ταῖς κατοικίσεσιν ἐχομένας ἐν χρόνου τινὸς μήκεσιν ἀπλέτοις, νῦν δὲ δὴ τετάρτη τις ἡμῖν αὕτη πόλις, εἰ δὲ βούλεσθε, ἔθνος ἥκει κατοικιζόμενόν τέ ποτε καὶ νῦν κατῳκισμένον.

about which you said truly that it and Crete were settled under kindred laws. From the wandering course of our argument, and our excursion through various polities and settlements, we have now gained this much: we have discerned a first, a second and a third State, all, as we suppose, succeeding one another in the settlements which took place during vast ages of time. And now there has emerged this fourth State—or nation, if you so prefer—which was once upon a time in course of establishment and is now established.
