The Assyro-Babylonian priests (Chaldeans) were the professional astrologers of classic antiquity. In its origin Chaldaic astrology also goes back to the worship of stars; this is proved by the religious symbolism of the most ancient cuneiform texts of the zodiac. The oldest astrological document extant is the work called "Namar-Beli" (Illumination of Bel) composed for King Sargon I (end of the third millennium B.C.) and contained in the cuneiform library of King Asurbanipal (668-626 B.C.). It includes astronomical observations and calculations of solar and lunar eclipses combined with astrological predictions, to which the interpretation of dreams already belonged. Even in the time of Chaldean, which should be called Assyrian, astrology, the five planets, together with the sun and moon, were divided according to their character and their position in the zodiac as well as according to their position in the twelve houses. As star of the sun, Saturn was the great planet and ruler of the heavens. The weather, as far back as this time, was predicted from the colour of the planets and from their rising and setting. Classical antiquity looked upon Berosus, priest of the temple of Bel at Babylon, as the oldest writer on astrology; and according to Vitruvius Berosus founded a school of astrology at Cos. Seneca says that a Greek translation, made by Berosus, of the "Namar-Beli" from the library the Asurbanipal was known to classical antiquity. The Egyptians and Hindus were as zealous astrologers as the nations on the Euphrates and Tigris. The dependence of the early Egyptian star (sun) worship (the basis of the worship of Osiris) upon early Chaldaic influences belongs to the still unsettled question of the origin of early Egyptian civilization. But undoubtly the priest of the Pharaohs were the docile pupils in astrology of the old Chaldean priests
