§2.5.1καὶ εὖ μοι ἐδόκεον λέγειν περὶ τῆς χώρης· δῆλα γὰρ δὴ καὶ μὴ προακούσαντι ἰδόντι δέ, ὅστις γε σύνεσιν ἔχει, ὅτι Αἴγυπτος, ἐς τὴν Ἕλληνες ναυτίλλονται, ἐστὶ Αἰγυπτίοισι ἐπίκτητός τε γῆ καὶ δῶρον τοῦ ποταμοῦ, καὶ τὰ κατύπερθε ἔτι τῆς λίμνης ταύτης μέχρι τριῶν ἡμερέων πλόου, τῆς πέρι ἐκεῖνοι οὐδὲν ἔτι τοιόνδε ἔλεγον, ἔστι δὲ ἕτερον τοιόνδε.
And they seemed to me to speak correctly about the country; for it is obvious, even to one who has not heard it beforehand but has seen it, provided he has understanding, that Egypt, to which the Greeks sail, is an acquired land for the Egyptians and a gift of the river, and also the region above this lake for as much as three days' voyage, concerning which those people said nothing more of this kind, though it is another of this sort.
§2.5.2Αἰγύπτου γὰρ φύσις ἐστὶ τῆς χώρης τοιήδε. πρῶτα μὲν προσπλέων ἔτι καὶ ἡμέρης δρόμον ἀπέχων ἀπὸ γῆς, κατεὶς καταπειρητηρίην πηλόν τε ἀνοίσεις καὶ ἐν ἕνδεκα ὀργυιῇσι ἔσεαι.
For the nature of the land of Egypt is as follows: first, as you sail towards it and are still a day's run distant from the land, if you let down a sounding-line, you will bring up mud and find yourself in eleven fathoms of water.
τοῦτο μὲν ἐπὶ τοσοῦτο δηλοῖ πρόχυσιν τῆς γῆς ἐοῦσαν.
This, on its part, shows that there is a silting up of the land to this extent.
