But out of this jungle of silly superstitions the elements of an enlightened and philosophical religion had evolved themselves in early Accadian times, and were continually developed as Semitic influences gradually fused themselves with Accadian, and formed the composite races and religions which came to be known in later times as Babylonian and Assyrian. The fundamental principle of this religion was the same as that of Egypt, and of most of the great religions of the East, viz. Pantheism. The great underlying First Cause, or Spirit of the universe, was considered as identical with his manifestations. The subtle metaphysical conceptions which still survive in the Creed of St. Athanasius, were invoked to make the incomprehensible comprehensible, by emanations, incarnations, and personified attributes. These again were attached to the striking phenomena of the universe, the sun, moon, and planets, the earth and sky, the winds, rains, and thunder. And ever as more phenomena were observed more gods were invented, who were thought to be symbols, or partial personifications, of the one great Spirit, and not more inconsistent with his unity than the "and yet there are not three Gods, but one God" of Athanasius. But the Chaldæan, like the Egyptian priests, did not stop at one Trinity, but invented a whole hierarchy of Trinities, rising one above the other to form the twelve great gods, while below them were an indefinite number of minor gods and goddesses personifying different aspects of natural phenomena, and taken for the most part from astronomical myths of the sun, moon, planets, and seasons. For the religion of the Chaldees was, even more than that of the Egyptians, based on astronomy and astrology, as may be seen in their national epic of Izdubar, which is simply a solar myth of the passage of the sun through the twelve signs of the zodiac, the last chapter but one being a representation of the passage through the sign of Aquarius, in the fable of a universal deluge.
