Herodotus on the Nile River (Book 2, chapters 19-35)
Sources: G. Rawlinson's translation of Herodotus's Histories, available online at the Internet Classics Archive.
Now the Nile, when it overflows, floods not only the Delta, but also the tracts of country on both sides the stream which are thought to belong to Libya and Arabia, in some places reaching to the extent of two days' journey from its banks, in some even exceeding that distance, but in others falling short of it.
Concerning the nature of the river, I was not able to gain any information either from the priests or from others. I was particularly anxious to learn from them why the Nile, at the commencement of the summer solstice, begins to rise, and continues to increase for a hundred days- and why, as soon as that number is past, it forthwith retires and contracts its stream, continuing low during the whole of the winter until the summer solstice comes round again. On none of these points could I obtain any explanation from the inhabitants, though I made every inquiry, wishing to know what was commonly reported- they could neither tell me what special virtue the Nile has which makes it so opposite in its nature to all other streams, nor why, unlike every other river, it gives forth no breezes from its surface.
Some of the Greeks, however, wishing to get a reputation for cleverness, have offered explanations of the phenomena of the river, for which they have accounted in three different ways. Two of these I do not think it worth while to speak of, further than simply to mention what they are. One pretends that the Etesian winds cause the rise of the river by preventing the Nile-water from running off into the sea. But in the first place it has often happened, when the Etesian winds did not blow, that the Nile has risen according to its usual wont; and further, if the Etesian winds produced the effect, the other rivers which flow in a direction opposite to those winds ought to present the same phenomena as the Nile, and the more so as they are all smaller streams, and have a weaker current. But these rivers, of which there are many both in Syria and Libya, are entirely unlike the Nile in this respect.
The second opinion is even more unscientific than the one just mentioned, and also, if I may so say, more marvellous. It is that the Nile acts so strangely, because it flows from the ocean, and that the ocean flows all round the earth.
The third explanation, which is very much more plausible than either of the others, is positively the furthest from the truth; for there is really nothing in what it says, any more than in the other theories. It is, that the inundation of the Nile is caused by the melting of snows. Now, as the Nile flows out of Libya, through Ethiopia, into Egypt, how is it possible that it can be formed of melted snow, running, as it does, from the hottest regions of the world into cooler countries? Many are the proofs whereby any one capable of reasoning on the subject may be convinced that it is most unlikely this should be the case. The first and strongest argument is furnished by the winds, which always blow hot from these regions. The second is that rain and frost are unknown there. Now whenever snow falls, it must of necessity rain within five days;.so that, if there were snow, there must be rain also in those parts. Thirdly, it is certain that the natives of the country are black with the heat, that the kites and the swallows remain there the whole year, and that the cranes, when they fly from the rigours of a Scythian winter, flock thither to pass the cold season. If then, in the country whence the Nile has its source, or in that through which it flows, there fell ever so little snow, it is absolutely impossible that any of these circumstances could take place.
As for the writer who attributes the phenomenon to the ocean, his account is involved in such obscurity that it is impossible to disprove it by argument. For my part I know of no river called Ocean, and I think that Homer, or one of the earlier poets, invented the name, and introduced it into his poetry.
Perhaps, after censuring all the opinions that have been put forward on this obscure subject, one ought to propose some theory of one's own. I will therefore proceed to explain what I think to be the reason of the Nile's swelling in the summer time. During the winter, the sun is driven out of his usual course by the storms, and removes to the upper parts of Libya. This is the whole secret in the fewest possible words; for it stands to reason that the country to which the Sun-god approaches the nearest, and which he passes most directly over, will be scantest of water, and that there the streams which feed the rivers will shrink the most.
To explain, however, more at length, the case is this. The sun, in his passage across the upper parts of Libya, affects them in the following way. As the air in those regions is constantly clear, and the country warm through the absence of cold winds, the sun in his passage across them acts upon them exactly as he wont to act elsewhere in summer, when his path is in the middle of heaven- that is, he attracts the water. After attracting it, he again repels it into the upper regions, where the winds lay hold of it, scatter it, and reduce it to a vapour, whence it naturally enough comes to pass that the winds which blow from this quarter- the south and south-west- are of all winds the most rainy. And my own opinion is that the sun does not get rid of all the water which he draws year by year from the Nile, but retains some about him. When the winter begins to soften, the sun goes back again to his old place in the middle of the heaven, and proceeds to attract water equally from all countries. Till then the other rivers run big, from the quantity of rain-water which they bring down from countries where so much moisture falls that all the land is cut into gullies; but in summer, when the showers fail, and the sun attracts their water, they become low. The Nile, on the contrary, not deriving any of its bulk from rains, and being in winter subject to the attraction of the sun, naturally runs at that season, unlike all other streams, with a less burthen of water than in the summer time. For in summer it is exposed to attraction equally with all other rivers, but in winter it suffers alone. The sun, therefore, I regard as the sole cause of the phenomenon.
It is the sun also, in my opinion, which, by heating the space through which it passes, makes the air in Egypt so dry. There is thus perpetual summer in the upper parts of Libya. Were the position of the heavenly regions reversed, so that the place where now the north wind and the winter have their dwelling became the station of the south wind and of the noon-day, while, on the other hand, the station of the south wind became that of the north, the consequence would be that the sun, driven from the mid-heaven by the winter and the northern gales, would betake himself to the upper parts of Europe, as he now does to those of Libya, and then I believe his passage across Europe would affect the Ister exactly as the Nile is affected at the present day.
And with respect to the fact that no breeze blows from the Nile, I am of opinion that no wind is likely to arise in very hot countries, for breezes love to blow from some cold quarter.
Let us leave these things, however, to their natural course, to continue as they are and have been from the beginning. With regard to the sources of the Nile, I have found no one among all those with whom I have conversed, whether Egyptians, Libyans, or Greeks, who professed to have any knowledge, except a single person. He was the scribe who kept the register of the sacred treasures of Minerva in the city of Sais, and he did not seem to me to be in earnest when he said that he knew them perfectly well. His story was as follows:- "Between Syene, a city of the Thebais, and Elephantine, there are" (he said) "two hills with sharp conical tops; the name of the one is Crophi, of the other, Mophi. Midway between them are the fountains of the Nile, fountains which it is impossible to fathom. Half the water runs northward into Egypt, half to the south towards Ethiopia." The fountains were known to be unfathomable, he declared, because Psammetichus, an Egyptian king, had made trial of them. He had caused a rope to be made, many thousand fathoms in length, and had sounded the fountain with it, but could find no bottom. By this the scribe gave me to understand, if there was any truth at all in what he said, that in this fountain there are certain strong eddies, and a regurgitation, owing to the force wherewith the water dashes against the mountains, and hence a Sounding-line cannot be got to reach the bottom of the spring.
No other information on this head could I obtain from any quarter. All that I succeeded in learning further of the more distant portions of the Nile, by ascending myself as high as Elephantine and making inquiries concerning the parts beyond, was the following:- As one advances beyond Elephantine, the land rises. Hence it is necessary in this part of the river to attach a rope to the boat on each side, as men harness an ox, and so proceed on the journey. If the rope snaps, the vessel is borne away down stream by the force of the current. The navigation continues the same for four days, the river winding greatly, like the Maeander, and the distance traversed amounting to twelve schoenes. Here you come upon a smooth and level plain, where the Nile flows in two branches, round an island called Tachompso. The country above Elephantine is inhabited by the Ethiopians, who possess one-half of this island, the Egyptians occupying the other. Above the island there is a great lake, the shores of which are inhabited by Ethiopian nomads; after passing it, you come again to the stream of the Nile, which runs into the lake. Here you land, and travel for forty days along the banks of the river, since it is impossible to proceed further in a boat on account of the sharp peaks which jut out from the water, and the sunken rocks which abound in that part of the stream. When you have passed this portion of the river in the space of forty days, you go on board another boat and proceed by water for twelve days more, at the end of which time you reach a great city called Meroe, which is said to be the capital of the other Ethiopians. The only gods worshipped by the inhabitants are Jupiter and Bacchus, to whom great honours are paid. There is an oracle of Jupiter in the city, which directs the warlike expeditions of the Ethiopians; when it commands they go to war, and in whatever direction it bids them march, thither straightway they carry their arms.
On leaving this city, and again mounting the stream, in the same space of time which it took you to reach the capital from Elephantine, you come to the Deserters, who bear the name of Asmach. This word, translated into our language, means "the men who stand on the left hand of the king." These Deserters are Egyptians of the warrior caste, who, to the number of two hundred and forty thousand, went over to the Ethiopians in the reign of king Psammetichus. The cause of their desertion was the following:- Three garrisons were maintained in Egypt at that time, one in the city of Elephantine against the Ethiopians, another in the Pelusiac Daphnae, against the Syrians and Arabians, and a third, against the Libyans, in Marea. (The very same posts are to this day occupied by the Persians, whose forces are in garrison both in Daphnae and in Elephantine.) Now it happened, that on one occasion the garrisons were not relieved during the space of three years; the soldiers, therefore, at the end of that time, consulted together, and having determined by common consent to revolt, marched away towards Ethiopia. Psammetichus, informed of the movement, set out in pursuit, and coming up with them, besought them with many words not to desert the gods of their country, nor abandon their wives and children. "Nay, but," said one of the deserters with an unseemly gesture, "wherever we go, we are sure enough of finding wives and children." Arrived in Ethiopia, they placed themselves at the disposal of the king. In return, he made them a present of a tract of land which belonged to certain Ethiopians with whom he was at feud, bidding them expel the inhabitants and take possession of their territory. From the time that this settlement was formed, their acquaintance with Egyptian manners has tended to civilise the Ethiopians.
Thus the course of the Nile is known, not only throughout Egypt, but to the extent of four months' journey either by land or water above the Egyptian boundary; for on calculation it will be found that it takes that length of time to travel from Elephantine to the country of the Deserters. There the direction of the river is from west to east. Beyond, no one has any certain knowledge of its course, since the country is uninhabited by reason of the excessive heat.
I did hear, indeed, what I will now relate, from certain natives of Cyrene. Once upon a time, they said, they were on a visit to the oracular shrine of Ammon, when it chanced that in the course of conversation with Etearchus, the Ammonian king, the talk fell upon the Nile, how that its sources were unknown to all men. Etearchus upon this mentioned that some Nasamonians had once come to his court, and when asked if they could give any information concerning the uninhabited parts of Libya, had told the following tale. (The Nasamonians are a Libyan race who occupy the Syrtis, and a tract of no great size towards the east.) They said there had grown up among them some wild young men, the sons of certain chiefs, who, when they came to man's estate, indulged in all manner of extravagancies, and among other things drew lots for five of their number to go and explore the desert parts of Libya, and try if they could not penetrate further than any had done previously. The coast of Libya along the sea which washes it to the north, throughout its entire length from Egypt to Cape Soloeis, which is its furthest point, is inhabited by Libyans of many distinct tribes who possess the whole tract except certain portions which belong to the Phoenicians and the Greeks. Above the coast-line and the country inhabited by the maritime tribes, Libya is full of wild beasts; while beyond the wild beast region there is a tract which is wholly sand, very scant of water, and utterly and entirely a desert. The young men therefore, despatched on this errand by their comrades with a plentiful supply of water and provisions, travelled at first through the inhabited region, passing which they came to the wild beast tract, whence they finally entered upon the desert, which they proceeded to cross in a direction from east to west. After journeying for many days over a wide extent of sand, they came at last to a plain where they observed trees growing; approaching them, and seeing fruit on them, they proceeded to gather it. While they were thus engaged, there came upon them some dwarfish men, under the middle height, who seized them and carried them off. The Nasamonians could not understand a word of their language, nor had they any acquaintance with the language of the Nasamonians. They were led across extensive marshes, and finally came to a town, where all the men were of the height of their conductors, and black-complexioned. A great river flowed by the town, running from west to east, and containing crocodiles.
Here let me dismiss Etearchus the Ammonian, and his story, only adding that (according to the Cyrenaeans) he declared that the Nasamonians got safe back to their country, and that the men whose city they had reached were a nation of sorcerers. With respect to the river which ran by their town, Etearchus conjectured it to be the Nile; and reason favours that view. For the Nile certainly flows out of Libya, dividing it down the middle, and as I conceive, judging the unknown from the known, rises at the same distance from its mouth as the Ister. This latter river has its source in the country of the Celts near the city Pyrene, and runs through the middle of Europe, dividing it into two portions. The Celts live beyond the pillars of Hercules, and border on the Cynesians, who dwell at the extreme west of Europe. Thus the Ister flows through the whole of Europe before it finally empties itself into the Euxine at Istria, one of the colonies of the Milesians.
Now as this river flows through regions that are inhabited, its course is perfectly well known; but of the sources of the Nile no one can give any account, since Libya, the country through which it passes, is desert and without inhabitants. As far as it was possible to get information by inquiry, I have given a description of the stream. It enters Egypt from the parts beyond. Egypt lies almost exactly opposite the mountainous portion of Cilicia, whence a lightly-equipped traveller may reach Sinope on the Euxine in five days by the direct route. Sinope lies opposite the place where the Ister falls into the sea. My opinion therefore is that the Nile, as it traverses the whole of Libya, is of equal length with the Ister. And here I take my leave of this subject.
