“In India the wheel was, moreover, connected with the title of a chakrayartin (from chakra=a wheel), the title meaning a supreme ruler or universal monarch, who ruled the four quarters of the world and on his coronation he had to drive his chariot or wheel to the four cardinal points to signify his conquest of them” (Wm. Simpson, Quarterly statement of Palestine Expl. Fund, 1895, p. 84). It is significant that “Mithra,” the god of the wheel, who was, as I shall show later on, likewise associated with the serpent, is represented with a chariot pulled by seven horses and thus to find the idea of centrifugal power, combined with the numeral seven and the conception of central rulership extending to the four quarters. While the above passages afford an interesting insight into the ancient significance and symbolism of the chariot, the use of which, with that of the throne was, originally, exclusively confined to the central supreme ruler, they also furnish a curious parallelism to the Chinese tours of inspection performed, by the emperor, to the four provinces in rotation. The general application of the quadruplicate system is moreover shown by the fact that, from time immemorial, the population of India has been divided into four great castes, and these are associated with distinctive colors, the Sanscrit word for color, _varna_, signifying also caste. According to the native myth, Brahma created the Brahmin or ruling caste from his mouth, the warrior caste from his arms and hands, the merchant and agricultural caste from his hips and the artisan or lowest caste from the soles of his feet. The warrior caste was named Kschatria; the people the yellow, or Vaicya; the original, conquered inhabitants of India were named the black, or Sudra. The Brahman caste was above all these.
