In the _Rigveda_ there is a water-nymph, named Apsaras; she is the “spouse” of Gandharva, an atmospheric deity who prepares Soma for the gods and reveals divine truths to mortals. They vanish, however, in later times; the other Vedas deal with the spirit groups which figure so prominently in the Epics. No doubt the groups are older than Gandharva, the god, and Apsaras, the goddess, who may be simply the elf-king and the fairy-queen. The “black” Dasyus are sometimes referred to by modern-day writers as the dark aborigines who were displaced by the Aryans; a tribal significance is also given to the Rakshasas and the Gandharvas. But this tendency to identify the creatures of the spirit world with human beings may be carried too far. If “Dasyus” were really “dark folk”,[125] it should be remembered that in Teutonic mythology there are “black dwarfs”, who live in underground dwellings, and “white elves” associated with air and ocean; there are also black and white fairies in the Scottish Highlands, so that black and white spirits may simply belong to night and day spirit groups. It may be that the Indian aborigines were referred to contemptuously as Dasyus by the Aryans. The application of the names of repulsive imps to human enemies is not an unfamiliar habit even in our own day; in China the European is a “foreign devil”, but Chinese “devils” existed long before Europeans secured a footing in the Celestial Kingdom. Those who seek for a rational explanation for the belief in the existence of mythical beings should remember that primitive man required no models for the creatures of his fancy. He symbolized everything—his ideals, his desires, his hopes and his fears, the howling wind, the low whispering breeze, the creaking tree, the torrent, the river, the lake, and the mountain; he heard the hammer or the trumpet of a mighty god in the thunderstorm, he believed that giants uprooted trees and cast boulders down mountain slopes, that demons raised ocean billows in tempest, and that the strife of the elements was a war between gods and giants; day and night, ever in conflict, were symbolized, as were also summer and winter, and growth and decay. If the fairies and elves of Europe are Lapps, or the small men of an interglacial period in the Pleistocene Age, and if the Dasyus and Gandharvas of India are merely Dravidians and pre-Dravidians who resisted the Aryan invasion, who, then, it may be asked, were the prototypes of the giants “big as mountains”, or the demons like “trees walking”, the “tiger-headed” Rakshasas, “ugly Vartikas” with “one wing, one eye, and one leg”? and what animal suggested Vritra, or the fiery dragon that burned up daylight, or Rahu, the swallower of sun and moon? If the redhaired and red-bearded Rakshasas are to be given a racial significance, what of the blue Rakshasas and the green? The idea that primitive man conceived of giants because he occasionally unearthed the bones of prehistoric
