We have still to tell of two other great men, Confucius and Lao Tse, who lived in that wonderful century which began the adolescence of mankind, the sixth century B.C. In this history thus far we have told very little of the early story of China. At present that early history is still very obscure, and we look to Chinese explorers and archæolologists in the new China that is now arising to work out their past as thoroughly as the European past has been worked out during the last century. Very long ago the first primitive Chinese civilizations arose in the great river valleys out of the primordial heliolithic culture. They had, like Egypt and Sumeria, the general characteristics of that culture, and they centred upon temples in which priests and priest kings offered the seasonal blood sacrifices. The life in those cities must have been very like the Egyptian and Sumerian life of six or seven thousand years ago and very like the Maya life of Central America a thousand years ago. If there were human sacrifices they had long given way to animal sacrifices before the dawn of history. And a form of picture writing was growing up long before a thousand years B.C. And just as the primitive civilizations of Europe and western Asia were in conflict with the nomads of the desert and the nomads of the north, so the primitive Chinese civilizations had a great cloud of nomadic peoples on their northern borders. There was a number of tribes akin in language and ways of living, who are spoken of in history in succession as the Huns, the Mongols, the Turks and Tartars. They changed and divided and combined and re-combined, just as the Nordic peoples in north Europe and central Asia changed and varied in name rather than in nature. These Mongolian nomads had horses earlier than the Nordic peoples, and it may be that in the region of the Altai Mountains they made an independent discovery of iron somewhen after 1000 B.C. And just as in the western case so ever and again these eastern nomads would achieve a sort of political unity, and become the conquerors and masters and revivers of this or that settled and civilized region.
