It requires no very profound knowledge of Greek religion and Greek language to discover in the Greek deities the original outlines of certain physical phenomena. Every schoolboy knows that in _Zeus_ there is something of the sky, in _Poseidon_ of the sea, in _Hades_ of the lower world, in _Apollo_ of the sun, in _Artemis_ of the moon, in _Hephæstos_ of the fire. But for all that, there is, from a Greek point of view, a very considerable difference between _Zeus_ and the sky, between _Poseidon_ and the sea, between _Apollo_ and the sun, between _Artemis_ and the moon. Now what do we find in the Veda? No doubt here and there a few philosophical hymns which have been quoted so often that people have begun to imagine that the Veda is a kind of collection of Orphic hymns. We also find some purely mythological hymns, in which the Devas or gods have assumed nearly as much dramatic personality as in the Homeric hymns. But the great majority of Vedic hymns consists in simple invocations of the fire, the water, the sky, the sun, and the storms, often under the same names which afterward became the proper names of Hindu deities, but as yet nearly free from all that can be called irrational or mythological. There is nothing irrational, nothing I mean we cannot enter into or sympathize with, in people imploring the storms to cease, or the sky to rain, or the sun to shine. I say there is nothing irrational in it, though perhaps it might be more accurate to say that there is nothing in it that would surprise anybody who is acquainted with the growth of human reason, or at all events, of childish reason. It does not matter how we call the tendency of the childish mind to confound the manifestation with that which manifests itself, effect with cause, act with agent. Call it Animism, Personification, Metaphor, or Poetry, we all know what is meant by it, in the most general sense of all these names; we all know that it exists, and the youngest child who beats the chair against which he has fallen, or who scolds his dog, or who sings: "Rain, rain, go to Spain," can teach us that, however irrational all this may seem to us, it is perfectly rational, natural, ay inevitable in the first periods, or the childish age of the human mind. Now it is exactly this period in the growth of ancient religion, which was always presupposed or postulated, but was absent everywhere else, that is clearly put before us in the hymns of the Rig-Veda. It is this ancient chapter in the history of the human mind which has been preserved to us in Indian literature, while we look for it in vain in Greece or Rome or elsewhere. It has been a favorite idea of those who call themselves "students of man," or anthropologists, that in order to know the earliest or so-called prehistoric phases in the growth of man, we should study the life of savage nations, as we may watch it still in some parts of Asia, Africa, Polynesia, and America.
