"Astrology (Gr.) The Science which defines the action of celestial bodies upon mundane affairs, and claims to foretell future events from the position of the stars. Its antiquity is such as to place it among the very earliest records of human learning. It remained for long ages a secret science in the East, and its final expression remains so to this day, its exoteric application having been brought to any degree of perfection in the West only during the period of time since Varaha Muhira wrote his book on Astrology some 1400 years ago. Claudius Ptolemy, the famous geographer and mathematician, wrote his treatise Tetrabiblos about 135 A.D., which is still the basis of modern astrology. The science of Horoscopy is studied now chiefly under four heads: viz., (1) Mundane, in its application to meteorology, seismology, husbandry, etc. (2) State or civic, in regard to the fate of nations, kings and rulers. (3) Horary, in reference to the solving of doubts arising in the mind upon any subject. (4) Genethliacal, in its application to the fate of individuals from the moment of their birth to their death. The Egyptians and the Chaldees were among the most ancient votaries of Astrology, though their modes of reading the stars and the modern practices differ considerably."
