Thus the physical characteristics of the country in which Babylonian civilization was developed, if it was not actually the place of its origin, form a close parallel to those of Lower Egypt; in Egypt however such evidence as there is, would indicate the South, or Upper Egypt as the earliest scene of civilization, the North being conquered by the Mesniu (Metal-users) of the South, not only in the battle-field but also in culture and civilization. Both countries have but a small sea-board where their rivers find an outlet, the Nile into the Mediterranean, and the Tigris and Euphrates into the Persian Gulf; both countries had emerged and were yearly emerging out of the sea, for it is certain that at one time the Mediterranean penetrated as far south as Esneh, while as already mentioned, the Persian Gulf extended at least as far as Babylon; we are accordingly not surprised to find in both the Babylonian and Egyptian cosmologies a tradition which told of the creation of the world out of a primæval mass of water, though this idea looms less conspicuously in the Egyptian than in the Babylonian and Hebrew cosmologies. Both countries also were visited by a yearly inundation which, while it brought no small amount of devastation in its train, at the same time deposited the mud so essential to the enrichment of the soil, the desolation being checked or at least mitigated in either country by an elaborate system of irrigation canals, which same canals were in the summer-time the means of conveying the life-giving water to the dry and thirsty land. Both Babylonia and Egypt enjoy a warm climate, though Egypt is much more dry and therefore healthier, and the corresponding dryness of its soil has preserved the tangible evidences of its ancient history in a far more perfect condition than the marsh-country of Lower Mesopotamia; and lastly the climate of Egypt is not subject to the same violent changes of temperature incidental to the seasons in the Valley of the Euphrates.
