The early Greek philosophers who visited Egypt and the East in search of knowledge, found very little to reward their curiosity or industry,--not much beyond preposterous claims to a high antiquity, and to an esoteric wisdom which has not yet been revealed. Plato and Eudoxus spent thirteen years in Heliopolis for the purpose of extracting the scientific knowledge of the Egyptian priests, yet they learned but little beyond the fact that the solar year was a trifle beyond three hundred and sixty-five days. No great names have come down to us from the priests of Babylon or Egypt; no one gained an individual reputation. The Chaldaean and Egyptian priests may have furnished the raw material of observation to the Greeks, but the latter alone possessed the scientific genius by which undigested facts were converted into a symmetrical system. The East never gave valuable knowledge to the West; it gave the tendency to religious mysticism, which in its turn tended to superstition. Instead of astronomy, it gave astrology; instead of science, it gave magic, incantations, and dreams. The Eastern astronomers connected their astronomy with divination from the stars, and made their antiquity reach back to two hundred and seventy thousand years. There were soothsayers in the time of Daniel, and magicians, exorcists, and interpreters of signs. They were not men of scientific research, seeking truth; it was power they sought, by perverting the intellect of the people. The astrology of the East was founded on the principle that a star or constellation presided over the birth of an individual, and that it either portended his fate, or shed a good or bad influence upon his future life. The star which looked upon a child at the hour of his birth was called the "horoscopus," and the peculiar influence of each planet was determined by the astrologers. The superstitions of Egypt and Chaldaea unfortunately spread among both the Greeks and Romans, and these were about all that the Western nations learned from the boastful priests of occult Oriental science. Whatever was known of real value among the ancients is due to the earnest inquiries of the Greeks.
