The History Of Herodotus Volume 1 of 2
Page: 8621. The second way shows more ignorance than that which has been mentioned, and it is more marvellous to tell; 28 for it says that the river produces these effects because it flows from the Ocean, and that the Ocean flows round the whole earth.
22. The third of the ways is much the most specious, but nevertheless it is the most mistaken of all: for indeed this way has no more truth in it than the rest, alleging as it does that the Nile flows from melting snow; whereas it flows out of Libya through the midst of the Ethiopians, and so comes out into Egypt. How then should it flow from snow, when it flows from the hottest parts to those which are cooler? And indeed most of the facts are such as to convince a man (one at least who is capable of reasoning about such matters), that it is not at all likely that it flows from snow. 29 The first and greatest evidence is afforded by the winds, which blow hot from these regions; the second is that the land is rainless always and without frost, whereas after snow has fallen rain must necessarily come within five days, so that if it snowed in those parts rain would fall there; the third evidence is afforded by the people dwelling there, who are of a black colour by reason of the burning heat. Moreover kites and swallows remain there through the year and do not leave the land; and cranes flying from the cold weather which comes on in the region of Scythia come regularly to these parts for wintering: if then it snowed ever so little in that land through which the Nile flows and in which it has its rise, none of these things would take place, as necessity compels us to admit.
23. As for him who talked about the Ocean, he carried his tale into the region of the unknown, and so he need not be refuted; 30 since I for my part know of no river Ocean existing, but I think that Homer or one of the poets who were before him invented the name and introduced it into his verse.
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.
