§3.20.1ἓν δὲ γένος τῶν Ἰχθυοφάγων τοιαύτας ἔχει τὰς οἰκήσεις ὥστε πολλὴν ἀπορίαν παρέχεσθαι τοῖς τὰ τοιαῦτα φιλοτιμουμένοις ζητεῖν· ἐν γὰρ ἀποκρήμνοις φάραγξι καθίδρυνταί τινες, εἰς ἃς ἐξ ἀρχῆς ἦν ἀδύνατον παραβάλλειν τοὺς ἀνθρώπους, ἄνωθεν μὲν ἐπεχούσης πέτρας ὑψηλῆς καὶ πανταχόθεν ἀποτόμου, ἐκ πλαγίων δὲ κρημνῶν ἀπροσίτων ὑφαιρουμένων τὰς παρόδους, τὴν δὲ λοιπὴν πλευρὰν τοῦ πελάγους ὁρίζοντος, ὃ πεζῇ μὲν διελθεῖν ἀδύνατον, σχεδίαις δὲ οὐ χρῶνται τὸ παράπαν, πλοίων τε τῶν παρʼ ἡμῖν ὑπάρχουσιν ἀνεννόητοι.
But one tribe of the Ichthyophagi has such dwellings that they present a great puzzle to those who are eager to investigate such matters; for some are settled in steep ravines into which it was impossible from the very beginning for men to enter, since a high and everywhere sheer rock overhangs them from above, while from the sides inaccessible cliffs block the passages, and the sea bounds the remaining side, which it is impossible to traverse on foot, and they do not use rafts at all, and have no conception of such ships as exist among us.
§3.20.2τοιαύτης δὲ ἀπορίας περὶ αὐτοὺς οὔσης, ὑπολείπεται λέγειν αὐτόχθονας αὐτοὺς ὑπάρχειν, ἀρχὴν μὲν τοῦ πρώτου γένους μηδεμίαν ἐσχηκότας, ἀεὶ δʼ ἐξ αἰῶνος γεγονότας, καθάπερ ἔνιοι τῶν φυσιολόγων περὶ πάντων τῶν φυσιολογουμένων ἀπεφήναντο.
Since there is such difficulty regarding them, it remains to say that they are indigenous, having had no beginning of their first origin, but having existed always from eternity, just as some of the natural philosophers have declared concerning all physical phenomena.
§3.20.3ἀλλὰ γὰρ περὶ μὲν τῶν τοιούτων ἀνεφίκτου τῆς ἐπινοίας ἡμῖν οὔσης οὐδὲν κωλύει τοὺς τὰ πλεῖστα ἀποφηναμένους ἐλάχιστα γινώσκειν, ὡς ἂν τῆς ἐν τοῖς λόγοις πιθανότητος τὴν μὲν ἀκοὴν πειθούσης, τὴν δʼ ἀλήθειαν οὐδαμῶς εὑρισκούσης.
But indeed, since the comprehension of such matters is beyond our reach, nothing prevents those who declare the most from knowing the least, inasmuch as the plausibility in arguments, while convincing the ear, in no way finds the truth.
