§2.20.1ἀλλὰ Ἑλλῄνων μὲν τινὲς ἐπίσημοι βουλόμενοι γενέσθαι σοφίην ἔλεξαν περὶ τοῦ ὕδατος τούτου τριφασίας ὁδούς· τῶν τὰς μὲν δύο τῶν ὁδῶν οὐδʼ ἀξιῶ μνησθῆναι εἰ μὴ ὅσον σημῆναι βουλόμενος μοῦνον·
But certain of the Greeks, wishing to become famous for wisdom, have offered three different explanations concerning this water; of these, there are two which I do not even think worth mentioning, except so far as I wish only to point them out.
§2.20.2τῶν ἡ ἑτέρη μὲν λέγει τοὺς ἐτησίας ἀνέμους εἶναι αἰτίους πληθύειν τὸν ποταμόν, κωλύοντας ἐς θάλασσαν ἐκρέειν τὸν Νεῖλον.
One of these says that the Etesian winds are the cause of the river's swelling, by preventing the Nile from flowing out into the sea.
πολλάκις δὲ ἐτησίαι μὲν οὔκων ἔπνευσαν, ὁ δὲ Νεῖλος τὠυτὸ ἐργάζεται.
But often the Etesian winds have not blown at all, yet the Nile does the very same thing.
§2.20.3πρὸς δέ, εἰ ἐτησίαι αἴτιοι ἦσαν, χρῆν καὶ τοὺς ἄλλους ποταμούς, ὅσοι τοῖσι ἐτησίῃσι ἀντίοι ῥέουσι, ὁμοίως πάσχειν καὶ κατὰ τὰ αὐτὰ τῷ Νείλῳ, καὶ μᾶλλον ἔτι τοσούτῳ ὅσῳ ἐλάσσονες ἐόντες ἀσθενέστερα τὰ ῥεύματα παρέχονται.
Moreover, if the Etesian winds were the cause, then all other rivers also, which flow contrary to the Etesian winds, ought to be affected in the same way and to the same degree as the Nile, and all the more so in proportion as they, being smaller, present weaker currents.
εἰσὶ δὲ πολλοὶ μὲν ἐν τῇ Συρίῃ ποταμοὶ πολλοὶ δὲ ἐν τῇ Λιβύῃ, οἳ οὐδὲν τοιοῦτο πάσχουσι οἷόν τι καὶ ὁ Νεῖλος.
Now there are many rivers in Syria and many in Libya, which are affected in no such way as the Nile is.
