Certain scholars in their researches after the origin of Aryan divinities, were surprised and somewhat disconcerted at a gap which confronted them and prevented further progress; nowhere in the later literature of India could any trace be found of Dyaus as a god who could correspond to the supreme divinity of the other branches of the family. However, the very rational conviction that this deity must have existed gradually strengthened in the minds of the learned. They were thus at a standstill, when the Veda appeared under the strong light of modern investigation and brought to view the name of Dyaus totally different from the feminine dyaus, a Dyaus presenting in itself, not merely the masculine substantive, but joined with pita--father. Amongst the Hindoos it had paled before Indra, who was a god of later date, but the other Aryan races had been uninfluenced by this. Dyaus, the chief god, had accompanied them in their migrations, and Zeus-pater, Ju-piter, Tyr, Tiw, and Zio, became the exact representative of him, each in a different country; this discovery of Dyaush-pita, was like finding at last a star in the very place of the heavens which had been fixed before by calculation, but where previously there had been a void. This was not the only discovery due to the study of the Veda. No one could ignore the fact, that amongst the Hindoos dyaus was the name of the sky, since it bears in itself the root which attests this; but it would have been impossible to discover the radical or predicative meaning of Zeus by the help of Greek alone; it possesses no certificate of birth, and the Greeks had no traditions connected with it that could have taught us. With the help of comparative philology all is made plain; Zeus was born when Dyaus was recognised as masculine and called father, Dyaush-pitar, Ju-piter, Zeus-pater, and from the moment that we are made acquainted with the origin of Zeus, the rest of his career unrolls before us. Our ancestors, however, had still a long time to wander in the wilderness of error, and lost themselves many times. The Hindoos thought for a time that they had found in Dyaus the object of their search; but the supernatural light and the light of day became confounded; when the word Dyaus was pronounced, the many natural bright objects it might signify all vibrated in response and melted into one; they became--as a double star does--one object, and Dyu, the god of light, was eclipsed behind dyu the sky.
