§4.42.1τοὺς αὐτοὺς τόπους.
(...to recognize) the same places.
ἐξ ὧν οὐκ εἰκὸς θαυμάζειν πῶς οἱ τηλικοῦτοι καὶ τοιοῦτοι ποταμοὶ συνεχῶς ῥέοντες ἀπεργάζονταί τι τῶν προειρημένων καὶ τέλος ἐκπληροῦσι τὸν Πόντον. §4.42.2οὐ γὰρ εἰκός, ἀλλʼ ἀναγκαῖον γενέσθαι τοῦτό γε προφαίνεται κατὰ τὸν ὀρθὸν λόγον. §4.42.3σημεῖον δὲ τοῦ μέλλοντος· ὅσῳ γάρ ἐστι νῦν ἡ Μαιῶτις γλυκυτέρα τῆς Ποντικῆς θαλάττης, οὕτως θεωρεῖται διαφέρουσα προφανῶς ἡ Ποντικὴ τῆς καθʼ ἡμᾶς. §4.42.4ἐξ ὧν δῆλον ὡς, ὅταν ὁ χρόνος, ἐν ᾧ πεπληρῶσθαι συμβαίνει τὴν Μαιῶτιν, τοῦτον λάβῃ τὸν λόγον πρὸς τὸν χρόνον, ὃν ἔχει τὸ μέγεθος τοῦ κοιλώματος πρὸς τὸ κοίλωμα, τότε συμβήσεται καὶ τὸν Πόντον τεναγώδη καὶ γλυκὺν καὶ λιμνώδη γενέσθαι παραπλησίως τῇ Μαιώτιδι λίμνῃ. §4.42.5καὶ θᾶττον δὲ τοῦτον ὑποληπτέον. ὅσῳ μείζους καὶ πλείους εἰσὶν αἱ ῥύσεις τῶν εἰς τοῦτον ἐκπιπτόντων ποταμῶν. §4.42.6ταῦτα μὲν οὖν ἡμῖν εἰρήσθω πρὸς τοὺς ἀπίστως διακειμένους, εἰ δὴ χώννυσθαι νῦν καὶ χωσθήσεσθαί ποτε συμβήσεται τὸν Πόντον καὶ λίμνη καὶ τέναγος ἔσται τὸ τηλικοῦτον πέλαγος. §4.42.7ἔτι δὲ μᾶλλον εἰρήσθω καὶ τῆς τῶν πλοϊζομένων ψευδολογίας καὶ τερατείας χάριν, ἵνα μὴ παντὶ τῷ λεγομένῳ προσκεχηνέναι παιδικῶς ἀναγκαζώμεθα διὰ τὴν ἀπειρίαν, ἔχοντες δʼ ἴχνη τῆς ἀληθείας ἐπὶ ποσὸν ἐξ αὐτῶν ἐπικρίνειν δυνώμεθα τὸ λεγόμενον ὑπό τινων ἀληθῶς ἢ τοὐναντίον. §4.42.8ἐπὶ δὲ τὸ συνεχὲς τῆς εὐκαιρίας τῶν Βυζαντίων ἐπάνιμεν.
From which it is not reasonable to wonder how such great and numerous rivers, flowing continuously, accomplish any of the aforementioned things and finally fill up the Pontus. For indeed, according to correct reasoning, this appears not merely probable, but necessary to happen. And here is the proof of what is to happen: for in proportion as the Maeotis is now fresher than the Pontic sea, so the Pontic is clearly seen to differ from our own sea. From which it is clear that, when the time in which the Maeotis is filled up bears to the time in which the Pontus is filled up the same ratio which the size of the basin of the former bears to the basin of the latter, then it will also happen that the Pontus will become shallow, fresh, and lake-like, in a similar manner to the Maeotian lake. And we must suppose this will happen even more quickly, inasmuch as the currents of the rivers emptying into this latter are larger and more numerous. Now, let this much be said by us to those who are incredulous as to whether it is happening now and will one day happen that the Pontus is silted up, and whether so great a sea will become a lake and a shallow. And still more let it be said because of the falsehood and love of the marvelous shown by those who sail the sea, so that we may not, through lack of experience, be forced to gape like children at everything that is told, but having some traces of the truth, we may be able to judge by their help whether what is said by anyone is true or the reverse. But we must return to the next part of our account of the advantageous position of Byzantium.
