There were few changes in the world in those days; men’s days were sunny, toilsome and conventional. Few strangers came into the land and such as did fared uncomfortably. The priest directed life according to immemorial rules and watched the stars for seed time and marked the omens of the sacrifices and interpreted the warnings of dreams. Men worked and loved and died, not unhappily, forgetful of the savage past of their race and heedless of its future. Sometimes the ruler was benign. Such was Pepi II, who reigned in Egypt for ninety years. Sometimes he was ambitious and took men’s sons to be soldiers and sent them against neighbouring city states to war and plunder, or he made them toil to build great buildings. Such were Cheops and Chephren and Mycerinus, who built those vast sepulchral piles, the pyramids at Gizeh. The largest of these is 450 feet high and the weight of stone in it is 4,883,000 tons. All this was brought down the Nile in boats and lugged into place chiefly by human muscle. Its erection must have exhausted Egypt more than a great war would have done. XVI PRIMITIVE NOMADIC PEOPLES It was not only in Mesopotamia and the Nile Valley that men were settling down to agriculture and the formation of city states in the centuries between 6000 and 8000 B.C. Wherever there were possibilities of irrigation and a steady all-the-year-round food supply men were exchanging the uncertainties and hardships of hunting and wandering for the routines of settlement. On the upper Tigris a people called the Assyrians were founding cities; in the valleys of Asia Minor and on the Mediterranean shores and islands, there were small communities growing up to civilization. Possibly parallel developments of human life were already going on in favourable regions of India, and China. In many parts of Europe where there were lakes well stocked with fish, little communities of men had long settled in dwellings built on piles over the water, and were eking out agriculture by fishing and hunting. But over much larger areas of the old world no such settlement was possible. The land was too harsh, too thickly wooded or too arid, or the seasons too uncertain for mankind, with only the implements and science of that age to take root. For settlement under the conditions of the primitive civilizations men needed a constant water supply and warmth and sunshine. Where these needs were not satisfied, man could live as a transient, as a hunter following his game, as a herdsman following the seasonal grass, but he could not settle. The transition from the hunting to the herding life may have been very gradual. From following herds of wild cattle or (in Asia) wild horses, men may have come to an idea of property in them, have learnt to pen them into valleys, have fought for them against wolves, wild dogs and other predatory beasts.
