Now, what happened in this instance with the name of Dyaus, happened again and again with other names. When men felt the presence of God in the great and strong wind, in the earthquake, or the fire, they said at first, He storms, He shakes, He burns. But they likewise said, the storm (Marut) blows, the fire (Agni) burns, the subterraneous fire (Vulcanus) upheaves the earth. And after a time the result was the same as before, and the words meaning originally wind or fire were used, under certain restrictions, as names of the unknown God. As long as all these names were remembered as mere names or attributes of one and the same Divine Power, there was as yet no polytheism, though, no doubt, every new name threatened to obscure more and more the primitive intuition of God. At first, the names of God, like fetishes or statues, were honest attempts at expressing or representing an idea which could never find an adequate expression or representation. But the eidolon, or likeness, became an idol; the nomen, or name, lapsed into a numen, or demon, as soon as they were drawn away from their original intention. If the Greeks had remembered that Zeus was but a name or symbol of the Deity, there would have been no more harm in calling God by that name than by any other. If they had remembered that Kronos, and Uranos, and Apollon were all but so many attempts at naming the various sides, or manifestations, or aspects, or persons of the Deity, they might have used these names in the hours of their various needs, just as the Jews called on Jehovah, Elohim, and Sabaoth, or as Roman Catholics implore the help of Nunziata, Dolores, and Notre-Dame-de-Grace.
