The History of Antiquity (Vol. 1-6). Duncker Max

high table-land is surrounded by a steep rampart of mountains, which descend in terraces to the coast, and here, almost without exception, leave narrow strips of low and marshy land. Through the barrier drawn around them by this rampart the rivers must force their path in a violent course, in waterfalls and rapids, in order to fall into the sea after a short, and proportionately more sluggish course through the narrow strip on the shore.

      The table-land, its rampart of mountains, and the long lines of coast, are, with the exception of the southern apex and the Alpine territory of Abyssinia in the east, the dwelling-places of the black race—the negro. However great the number of negro nations and tribes, however much they differ in physical form and in dialect—living as they do beneath a vertical sun, in regions difficult of access—they have never risen beyond the infancy of human civilisation—a rude worship of gods. Wherever they have not been powerfully affected by the introduction of foreign elements, generation has followed generation without remembrance or essential alteration.

      The north coast of Africa is of a different character to the rest of the continent. While the western coast looks to the broad Atlantic Ocean, and the waves which break on the southern apex lead to the ice of the pole, the north coast is separated from the neighbouring shores by a basin of moderate extent. It is a mountainous district which fills up the space between the Sahara and the Mediterranean. Towards the west the peaks of Atlas reach, even in this climate, to the region of eternal snow; on the east, towards the mouths of the Nile, the hills gradually sink down, and the plain of Barca rises little more than 1,000 feet above the sea level. Numerous chains of hills, at one time pressing close upon the sea, at another leaving more extensive plains upon the coast, cover the northern edge, which along the deep valleys of the mountain streams exhibits that vigorous and luxuriant vegetation so characteristic of Africa when not checked by want of water, although even these fruitful valleys are again in their turn broken by droughty, and therefore bare, table-lands and depressions.

      On this northern coast, toward the Mediterranean, opens the valley which, in extent of fruitful territory, is the largest in the whole continent. It occupies the north-east corner of Africa, which is only separated from Arabia by a narrow strip of sea, and carries its gleaming waters through the wide space from the subsidence of the table-land down to the coast, where for almost its whole remaining breadth the continent is filled up with the desert of Sahara.

      From the north-east spur of the table-land, out of vast lakes (Ukerewe), fed from the glaciers and snows of huge mountains lying under the equator, and passing through the lower lake Mwutan, flows the western arm of the Nile, the White Nile, Bahr-el-Abiad. After bursting through the terraces of the mountain, it reaches, at the foot, a woody morass, filled with thickets of tamarisks and sycamores, of bamboo and reeds and tall creepers, inhabited by the elephant and rhinoceros, the hippopotamus and the crocodile, the zebra and hyena, by antelopes and snakes. Then the stream passes into broad savannas, covered here and there with tropic forests, and while flowing through a mountainous district of moderate elevation, it unites with the eastern arm, the Blue Nile, Bahr-el-Azrak, which, rising further to the east out of the Abyssinian plateau, brings down a far smaller bulk of water from the Alpine glades of the snowy mountain Samen. Combined into one stream, these waters flow through a broad expanse of rock and desert, covered with conical stones of volcanic origin. The lines of hills running parallel to the terraces of the mountain rampart lie athwart the river; and through this barrier it breaks in numerous cataracts. Only in the depressions between them can the soil, refreshed with water, support vegetation. Finally, at Syene the Nile passes through the last cataract. Henceforward the structure of the mountains is changed. A fissure in the rock about 750 miles long opens on the Mediterranean; and through this the mighty river—at the last cataract it is 3,000 feet in breadth—can flow onward in undisturbed peace to the ocean.

      Out of this fissure the Nile has created a narrow strip of fruitful soil—the valley is not more than three or four hours in breadth on an average—which is secured by the heights on the west from the moving sand and the storms of the great desert, and is separated by the mountain on the east from the rocky crags, the desolate flats, and sandy dunes which fill up the space between the valley of the river and the Red Sea. To this valley the mighty river not only gives a refreshing coolness and moisture by the mass of its waters, it fertilises and manures it from year to year by its overflow. At the summer solstice, when the snow on the peaks of the lofty mountains, in which the two arms of the Nile take their rise, is melting, and the tropical rains fall upon its upper course, the waters of the river slowly and gradually rise. Towards the end of July it passes over the banks and overflows the whole valley as far as the enclosing lines of hills, so that towards the end of September it stands more than twenty feet above the lowest water level. Falling as gradually as it rose after more than four months it sinks back to the ordinary level. Wherever the overflowing waters have covered the land, there is left behind a fertilising mud or slime. This is the soil which the two rivers before uniting have washed from the upper hills. Carried down by the stream, it is deposited by the gentle flow of the waters on the surface of the valley. The refreshment of the earth by the inundation, the fertilisation by this slime, and the cooling of the air by the immense body of water, are the essential advantages which Egypt owes to her river, and hence, even as early as Herodotus, Egypt seemed to be the gift of the Nile. The watering of the soil and the cooling of the air just in the very hottest months of the year, are the more invaluable because the blue and gleaming sky of the upper valley is never darkened by rain clouds, while the heat is severe, and the storms from the south-west occasionally carry the sand and the dust over the Libyan hills into the Nile. In the Delta, the region along the lowest course of the Nile, showers occasionally rise from the neighbouring sea; and through eight months of the year the whole valley opening on the Mediterranean is fanned by refreshing winds from the north, which also facilitate navigation against the stream.

      This river-valley, the like of which in nature and formation is not to be found in the whole globe, offered in its seclusion a peculiarly favoured spot. It was a small green oasis of luxuriant fertility and grateful coolness in the midst of boundless deserts. The dwellers in a land whose soil was every year newly manured by nature, which brought forth abundantly almost without labour, must very soon have abandoned a pastoral life for agriculture, and in consequence have acquired fixed abodes and settled possessions. But the yearly inundation compelled them also at an early period to protect their flocks from the water, to secure their habitations, to observe the periods of the rising and falling of the stream. The long duration of the overflow made it necessary to provide for the support of man and beast. They had to learn how to carry on their dealings with each other upon the water, when the whole valley was still filled with the river, and to mark out firmly the limits of their plots, so that they might again take possession of them after the inundation. In Nubia the cataracts stopped the navigation of the river, and the lines of rock and strips of desert made intercourse difficult, and confined the life of the tribes within the limits of the native valley to their separate possessions. In Egypt, within the two lines of hills, land and river created no hindrance. A region so concentrated could not but carry the tribes beyond the limits of separate existence; the very land forced them to live a life more in common. There was only a slight natural distinction between the more secluded upper valley and the lower opening in the Delta about the mouths of the Nile; and this could merely have a stimulating effect upon the development of culture, without interfering in any way with its unity. Nevertheless the community of life in the valley of the Nile was not caused solely by the nature of the land. The tribes of the deserts around this long and narrow oasis must have had all the more lively a sense of the charm of the favoured valley owing to the difficulty with which they procured their own subsistence. Against these plundering neighbours, and their attempts to force themselves into the valley of blessing and abundance, the inhabitants of Egypt had to combine their forces. They needed a strong centralized command, a warlike monarchy, to which here, earlier than elsewhere, the patriarchal government of the tribes would therefore give way.

      Egypt kept her inhabitants secluded within hard and fast limits; beyond the hills began the desert. With the increasing number of inhabitants the attempt must have been made to set low-lying marshy districts free from the excess of water, and to make fruitful the higher parts of the valley beyond the reach of the inundations by bringing the water upon them. Experience quickly taught that the plot produced the most abundant fruits on which the inundation had
