Religion like everything else had undergone great refinement. Human sacrifice for instance had long since disappeared; animals or bread dummies had been substituted for the victim. (But the Phœnicians and especially the citizens of Carthage, their greatest settlement in Africa, were accused, later of immolating human beings.) When a great chief had died in the ancient days it had been customary to sacrifice his wives and slaves and break spear and bow at his tomb so that he should not go unattended and unarmed in the spirit world. In Egypt there survived of this dark tradition the pleasant custom of burying small models of house and shop and servants and cattle with the dead, models that give us to-day the liveliest realization of the safe and cultivated life of these ancient people, three thousand years and more ago. THE TEMPLE OF HORUS AT EDFU THE TEMPLE OF HORUS AT EDFU Such was the ancient world before the coming of the Aryans out of the northern forests and plains. In India and China there were parallel developments. In the great valleys of both these regions agricultural city states of brownish peoples were growing up, but in India they do not seem to have advanced or coalesced so rapidly as the city states of Mesopotamia or Egypt. They were nearer the level of the ancient Sumerians or of the Maya civilization of America. Chinese history has still to be modernized by Chinese scholars and cleared of much legendary matter. Probably China at this time was in advance of India. Contemporary with the seventeenth dynasty in Egypt, there was a dynasty of emperors in China, the Shang dynasty, priest emperors over a loose-knit empire of subordinate kings. The chief duty of these early emperors was to perform the seasonal sacrifices. Beautiful bronze vessels from the time of the Shang dynasty still exist, and their beauty and workmanship compel us to recognize that many centuries of civilization must have preceded their manufacture. XIX THE PRIMITIVE ARYANS Four thousand years ago, that is to say about 2000 B.C., central and south-eastern Europe and central Asia were probably warmer, moister and better wooded than they are now. In these regions of the earth wandered a group of tribes mainly of the fair and blue-eyed Nordic race, sufficiently in touch with one another to speak merely variations of one common language from the Rhine to the Caspian Sea. At that time they may not have been a very numerous people, and their existence was unsuspected by the Babylonians to whom Hammurabi was giving laws, or by the already ancient and cultivated land of Egypt which was tasting in those days for the first time the bitterness of foreign conquest.
