2.17.6
The Bolbitine and Bucolic mouths are not natural but excavated channels.
ch. 18
2.18.1
The response of oracle of Ammon in fact bears witness to my opinion, that Egypt is of such an extent as I have argued; I learned this by inquiry after my judgment was already formed about Egypt.
2.18.2
The men of the cities of Marea and Apis, in the part of Egypt bordering on Libya, believing themselves to be Libyans and not Egyptians, and disliking the injunction of the religious law that forbade them to eat cows' meat, sent to Ammon saying that they had no part of or lot with Egypt: for they lived (they said) outside the Delta and did not consent to the ways of its people, and they wished to be allowed to eat all foods.
2.18.3
But the god forbade them: all the land, he said, watered by the Nile in its course was Egypt, and all who lived lower down than the city Elephantine and drank the river's water were Egyptians. Such was the oracle given to them.
ch. 19
2.19.1
When the Nile is in flood, it overflows not only the Delta but also the lands called Libyan and Arabian, as far as two days' journey from either bank in places, and sometimes more than this, sometimes less. Concerning its nature, I could not learn anything either from the priests or from any others.
2.19.2
Yet I was anxious to learn from them why the Nile comes down with a rising flood for a hundred days from the summer solstice; and when this number of days is passed, sinks again with a diminishing stream, so that the river is low for the whole winter until the summer solstice again.
2.19.3
I was not able to get any information from any of the Egyptians regarding this, when I asked them what power the Nile has to be contrary in nature to all other rivers. I wished to know this, and asked; also, why no breezes blew from it as from every other river note.
ch. 20
2.20.1
But some of the Greeks, wishing to be notable for cleverness, put forward three opinions about this river, two of which I would not even mention except just to show what they are.
2.20.2
One of them maintains that the Etesian winds note are the cause of the river being in flood, because they hinder the Nile from emptying into the sea. But there are many times when the Etesian winds do not blow, yet the Nile does the same as before.
2.20.3
And further, if the Etesian winds were the cause, then the other rivers which flow contrary to those winds should be affected like the Nile, and even more so, since being smaller they have a weaker current. Yet there are many rivers in Syria and many in Libya, and they behave nothing like the Nile.
ch. 21
2.21.1
The second opinion is less grounded on knowledge than the previous, though it is more marvellous to the ear: according to it, the river effects what it does because it flows from Ocean, which flows around the whole world.
ch. 22
2.22.1
The third opinion is by far the most plausible, yet the most erroneous of all. It has no more truth in it than the others. According to this, the Nile flows from where snows melt; but it flows from Libya through the midst of Ethiopia, and comes out into Egypt.
