In the same manner, although Persia has in general preserved the personality of her Supreme god, yet she suffers him, especially in the sects, to become confounded with the Infinity of matter through which he first revealed himself to the mind of his worshippers. After having invoked the heavens as the body of Ahura Mazda, the most beautiful of bodies, she placed above Ahura himself, and before him, the luminous space, where he manifests himself, what the theologians called "the Infinite light," and then by a new and higher abstraction declared _Space_[54] to have been at the beginning of the world. Between this wholly metaphysical principle and the naturalistic principle of the primitive religion, there is only the distance of two abstractions: Space is only the bare form of the luminous Infinite, and the luminous Infinite, again, is an abstraction from the Infinite and luminous sky, which was identical with Ahura. Thus, accordingly as the heavens were considered as the seat or as the cause of things, the god of the heavens became the matter of the world or the demiurge of the world. From the period of Aryan unity, he was without doubt the one and the other in turn; but it is probable that the theistic conception was more clearly defined than the other, as it is so in the derived mythologies; it has besides deeper roots in the human heart and human nature, which in every movement and in every phenomenon sees a Living Cause, a Personality. This god of the heavens, having organized the world, is all wisdom; he is the skilled artisan who has regulated the motion of the worlds. His wisdom is infinite, for of all those mysteries which man tries in vain to fathom he has the key, he is the author. But it is not only as the Creator of the world that he is omniscient: he knows all things, because, being all light, he sees all things. In the naturalistic psychology of the Aryans, to see and to know, light and knowledge, eye and thought, are synonymous terms. With the Hindoos, Varuna is omniscient because he is the Infinite light; because the sun is his eye; because from the height of his palace with its pillars of red brass, his white looks command the world; because under the golden mantle that covers him, his thousands, his myriads of spies, active and untiring agents, sunbeams during the day, stars during the night, search out for him all that which exists from one world to the other, with eyes that never sleep, never blink. And in the same way, if Zeus is the all-seeing, the πανόπτης, it is because his eye is the sun, this universal witness, the infallible spy of both gods and men (Θεῶν σκοπὸν ἠδὲ καὶ ἀνδρῶν). The light knows the truth, it is all truth; truth is the great virtue which the god of heaven claims; and lying is the great crime which he punishes. In Homer, the Greek taking an oath, raises his eyes towards the expanse of heaven and calls Zeus and the sun to witness; in Persia, the god of heaven resembles in body the light, and
