The Nile then, besides the part of its course which is in Egypt, is known as far as a four months’ journey by river and land: for that is the number of months which are found by reckoning to be spent in going from Elephantine to these “Deserters”: and the river runs from the West and the setting of the sun. But what comes after that point no one can clearly say; for this land is desert by reason of the burning heat.
This much however I heard from men of Kyrene, who told me that they had been to the Oracle of Ammon, and had come to speech with Etearchos king of the Ammonians: and it happened that after speaking of other matters they fell to discourse about the Nile and how no one knew the sources of it; and Etearchos said that once there came to him men of the Nasamonians (this is a Libyan race which dwells in the Syrtis, and also in the land to the East of the Syrtis reaching to no great distance), and when the Nasamonians came and were asked by him whether they were able to tell him anything more than he knew about the desert parts of Libya, they said that there had been among them certain sons of chief men, who were of unruly disposition; and these when they grew up to be men had devised various other extravagant things and also they had told off by lot five of themselves to go to see the desert parts of Libya and to try whether they could discover more than those who had previously explored furthest: for in those parts of Libya which are by the Northern Sea, beginning from Egypt and going as far as the headland of Soloeis, which is the extreme point of Libya, Libyans (and of them many races) extend along the whole coast, except so much as the Hellenes and Phenicians hold; but in the upper parts, which lie above the sea-coast and above those people whose land comes down to the sea, Libya is full of wild beasts; and in the parts above the land of wild beasts it is full of sand, terribly waterless and utterly desert. These young men then (said they), being sent out by their companions well furnished with supplies of water and provisions, went first through the inhabited country, and after they had passed through this they came to the country of wild beasts, and after this they passed through the desert, making their journey towards the West Wind; and having passed through a great tract of sand in many days, they saw at last trees growing in a level place; and having come up to them, they were beginning to pluck the fruit which was upon the trees: but as they began to pluck it, there came upon them small men, of less stature than men of the common size, and these seized them and carried them away; and neither could the Nasamonians understand anything of their speech nor could those who were carrying them off understand anything of the speech of the Nasamonians; and they led them (so it was said) through very great swamps, and after passing through these they came to a city in which all the men were in size like those who carried them off and in colour of skin black; and by the city ran a great river, which ran from the West towards the sunrising, and in it were seen crocodiles. Of the account given by Etearchos the Ammonian let so much suffice as is here said, except that, as the men of Kyrene told me, he alleged that the Nasamonians returned safe home, and that the people to whom they had come were all wizards.
Now this river which ran by the city, Etearchos conjectured to be the Nile, and moreover reason compels us to think so; for the Nile flows from Libya and cuts Libya through in the midst, and as I conjecture, judging of what is not known by that which is evident to the view, it starts at a distance from its mouth equal to that of the Ister: for the river Ister begins from the Keltoi and the city of Pyrene and so runs that it divides Europe in the midst (now the Keltoi are outside the Pillars of Heracles and border upon the Kynesians, who dwell furthest towards the sunset of all those who have their dwelling in Europe): and the Ister ends, having its course through the whole of Europe, by flowing into the Euxine Sea at the place where the Milesians have their settlement of Istria. Now the Ister, since it flows through land which is inhabited, is known by the reports of many; but of the sources of the Nile no one can give an account, for the part of Libya through which it flows is uninhabited and desert. About its course however so much as it was possible to learn by the most diligent inquiry has been told; and it runs out into Egypt. Now Egypt lies nearly opposite to the mountain districts of Kilikia; and from thence to Sinope, which lies upon the Euxine Sea, is a journey in the same straight line of five days for a man without encumbrance; and Sinope lies opposite to the place where the Ister runs out into the sea: thus I think that the Nile passes through the whole of Libya and is of equal measure with the Ister. Of the Nile then let so much suffice as has been said.
Of Egypt however I shall make my report at length, because it has wonders more in number than any other land, and works too it has to show as much as any land, which are beyond expression great: for this reason then more shall be said concerning it.
