these parts is dry, since he makes it so by scorching up his path through the heaven: 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 he would do to the Ister that which he now works upon the Nile. 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. 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 Sais 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 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 thousand fathoms and let it down in this place, and it found no bottom. By this the scribe (if this which he told was really as he said) gave me to understand 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. 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; 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
