24. If however after I have found fault with the opinions proposed, I am bound to declare an opinion of my own about the matters which are in doubt, I will tell what to my mind is the reason why the Nile increases in the summer. In the winter season the Sun, being driven away from his former path through the heaven[31] by the stormy winds, comes to the upper parts of Libya. If one would set forth the matter in the shortest way, all has now been said; for whatever region this god approaches most and stands directly above, this it may reasonably be supposed is most in want of water, and its native streams of rivers are dried up most. 25. However, to set it forth at greater length, thus it is: — the Sun passing in his course by the upper parts of Libya, does thus, that is to say, since at all times the air in those parts is clear and the country is warm, because there are no cold winds,[32] in passing through it the Sun does just as he was wont to do in the summer, when going through the midst of the heaven, that is he draws to himself the water, and having drawn it he drives it away to the upper parts of the country, and the winds take it up and scattering it abroad melt it into rain; so it is natural that the winds which blow from this region, namely the South and South-west Winds, should be much the most rainy of all the winds. I think however that the Sun does not send away from himself all the water of the Nile of each year, but that he also lets some remain behind with himself. Then when the winter becomes milder, the Sun returns back again to the midst of the heaven, and from that time onwards he draws equally from all rivers; but in the meanwhile they flow in large volume, since water of rain mingles with them in great quantity, because their country receives rain then and is filled with torrent streams. In summer however they are weak, since not only the showers of rain fail then, but also they are drawn by the Sun. The Nile however, alone of all rivers, not having rain and being drawn by the Sun, naturally flows during this time of winter in much less than its proper volume, that is much less than in summer;[33] for then it is drawn equally with all the other waters, but in winter it bears the burden alone. Thus I suppose the Sun to be the cause of these things. 26. He is also the cause in my opinion that the air in these parts is dry, since he makes it so by scorching up his path through the heaven:[34] thus summer prevails always in the upper parts of Libya. If however the station of the seasons had been changed, and where now in the heaven are placed the North Wind and winter, there was the station of the South Wind and of the midday, and where now is placed the South Wind, there was the North, if this had been so, the Sun being driven from the midst of the heaven by the winter and the North Wind would go to the upper parts of Europe, just as now he comes to the upper parts of Libya, and passing in his course throughout the whole of Europe I suppose that he would do to the Ister that which he now works upon the Nile. 27. As to the breeze, why none blows from the river, my opinion is that from very hot places it is not natural that anything should blow, and that a breeze is wont to blow from something cold.

28. Let these matters then be as they are and as they were at the first: but as to the sources of the Nile, not one either of the Egyptians or of the Libyans or of the Hellenes, who came to speech with me, professed to know anything, except the scribe of the sacred treasury of Athene at the city of Saás in Egypt. To me however this man seemed not to be speaking seriously when he said that he had certain knowledge of it; and he said as follows, namely that there were two mountains of which the tops ran up to a sharp point, situated between the city of Syene, which is in the district of Thebes, and Elephantine, and the names of the mountains were, of the one Crophi and of the other Mophi. From the middle between these two mountains flowed (he said) the sources of the Nile, which were fathomless in depth, and half of the water flowed to Egypt and towards the North Wind, the other half to Ethiopia and the South Wind. As for the fathomless depth of the source, he said that Psammetichos king of Egypt came to a trial of this matter; for he had a rope twisted of many thousands of fathoms and let it down in this place, and it found no bottom. By this the scribe (if this which he told me was really as he said) gave me to understand[35] that there were certain strong eddies there and a backward flow, and that since the water dashed against the mountains, therefore the sounding-line could not come to any bottom when it was let down. 29. From no other person was I able to learn anything about this matter; but for the rest I learnt so much as here follows by the most diligent inquiry;[36] for I went myself as an eye-witness as far as the city of Elephantine and from that point onwards I gathered knowledge by report. From the city of Elephantine as one goes up the river there is country which slopes steeply; so that here one must attach ropes to the vessel on both sides, as one fastens an ox, and so make one’s way onward; and if the rope break, the vessel is gone at once, carried away by the violence of the stream. Through this country it is a voyage of about four days in length, and in this part the Nile is winding like the river Maiander, and the distance amounts to twelve schoines, which one must traverse in this manner. Then you will come to a level plain, in which the Nile flows round an island named Tachompso. (Now in the regions above Elephantine there dwell Ethiopians at once succeeding, who also occupy half of the island,[37] and Egyptians the other half.) Adjoining this island there is a great lake, round which dwell Ethiopian nomad tribes; and when you have sailed through this you will come to the stream of the Nile again, which flows into this lake. After this you will disembark and make a journey by land of forty days; for in the Nile sharp rocks stand forth out of the water, and there are many reefs, by which it is not possible for a vessel to pass. Then after having passed through this country in the forty days which I have said, you will embark again in another vessel and sail for twelve days; and after this you will come to a great city called Meroe. This city is said to be the mother-city of all the other Ethiopians: and they who dwell in it reverence of the gods Zeus and Dionysos alone, and these they greatly honour; and they have an Oracle of Zeus established, and make warlike marches whensoever this god commands them by prophesyings and to whatsoever place he commands. 30. Sailing from this city you will come to the “Deserters” in another period of time equal to that in which you came from Elephantine to the mother- city of the Ethiopians. Now the name of these “Deserters” is Asmach, and this word signifies, when translated into the tongue of the Hellenes, “those who stand on the left hand of the king.” These were two hundred and forty thousand Egyptians of the warrior class, who revolted and went over to the Ethiopians for the following cause: — In the reign of Psammetichos garrisons were set, one towards the Ethiopians at the city of Elephantine, another towards the Arabians and Assyrians at Daphnai of Pelusion, and another towards Libya at Marea: and even in my own time the garrisons of the Persians too are ordered in the same manner as these were in the reign of Psammetichos, for both at Elephantine and at Daphnai the Persians have outposts. The Egyptians then of whom I speak had served as outposts for three years and no one relieved them from their guard; accordingly they took counsel together, and adopting a common plan they all in a body revolted from Psammetichos and set out for Ethiopia. Hearing this Psammetichos set forth in pursuit, and when he came up with them he entreated them much and endeavoured to persuade them not to desert the gods of their country and their children and wives: upon which it is said that one of them pointed to his privy member and said that wherever this was, there would they have both children and wives. When these came to Ethiopia they gave themselves over to the king of the Ethiopians; and he rewarded them as follows: — there were certain of the Ethiopians who had come to be at variance with him; and he bade them drive these out and dwell in their land. So since these men settled in the land of the Ethiopians, the Ethiopians have come to be of milder manners, from having learnt the customs of the Egyptians.

31. The Nile then, besides that 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 no one can clearly say; for this land is desert by reason of the burning heat. 32. Thus 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 had come 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. 33. 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. 34. 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;[37a] 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.
