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
