First a Semitic tribe, but later the magi of Babylonia, astrologers and diviners. From among them came "the wise men from the East.
We know little of Chaldaean astrology, but some idea of their teachings are to be gleaned from the Chaldaean Oracles. With them Astrology was a religion, but of a far different type from any which has survived to modern times. The Chaldaean priests were famous Astrologers. They held that the world is eternal, without beginning or end; that all things are ordered by Divine providence; and that the Sun, Mars, Venus, Mercury and Jupiter are "interpreters," concerned with making known to man the will of God.
From the regularity of motions in the heavenly bodies, they inferred that they were either intelligent beings, or were under some presiding intelligence. From this arose Sabianism, the worship of the host of heaven: Sun, Moon and Stars. It originated with the Arabian kingdom of Saba (Sheba), whence came the Queen of Sheba. The chief object of their worship was the Sun, Belus. To him was erected the tower of Belus, and the image of Belus.
They did not worship the stars as God, who they thought of as too great to be concerned with mundane affairs; but they worshipped those whom they believed He had appointed as mediators between God and man. Their religion was based upon a belief in one impersonal, universal Principle, but to which they gave no name. To their lesser gods they erected huge temples, of a peculiar construction, specially adapted for star worship. Here they healed the sick, and performed certain magical ceremonies.
An inscription on the pedestal of a statue erected to Nebo, reads: "To the god Nebo, guardian of the mysteries, director of the stars: he who presides at the rising and setting of the sun; whose power is immutable, and for whom the heaven was created." In the time of Alexander the Great, 356 B.C., the Chaldaeans alleged that their Astrology had existed 473,000 years
