"Should it be asked at what epoch this system took its birth, we shall answer on the testimony of the monuments of astronomy itself; that its principles appear with certainty to have been established about seventeen thousand years ago,* and if it be asked to what people it is to be attributed, we shall answer that the same monuments, supported by unanimous traditions, attribute it to the first tribes of Egypt; and when reason finds in that country all the circumstances which could lead to such a system; when it finds there a zone of sky, bordering on the tropic, equally free from the rains of the equator and the fogs of the North;** when it finds there a central point of the sphere of the ancients, a salubrious climate, a great, but manageable river, a soil fertile without art or labor, inundated without morbid exhalations, and placed between two seas which communicate with the richest countries, it conceives that the inhabitant of the Nile, addicted to agriculture from the nature of his soil, to geometry from the annual necessity of measuring his lands, to commerce from the facility of communications, to astronomy from the state of his sky, always open to observation, must have been the first to pass from the savage to the social state; and consequently to attain the physical and moral sciences necessary to civilized life. * The historical orator follows here the opinion of M. Dupuis, who, in his learned memoirs concerning the Origin of the Constellations and Origin of all Worship, has assigned many plausible reasons to prove that Libra was formerly the sign of the vernal, and Aries of the autumnal equinox; that is, that since the origin of the actual astronomical system, the precession of the equinoxes has carried forward by seven signs the primitive order of the zodiac. Now estimating the precession at about seventy years and a half to a degree, that is, 2,115 years to each sign; and observing that Aries was in its fifteenth degree, 1,447 years before Christ, it follows that the first degree of Libra could not have coincided with the vernal equinox more lately than 15,194 years before Christ; now, if you add 1790 years since Christ, it appears that 16,984 years have elapsed since the origin of the Zodiac. The vernal equinox coincided with the first degree of Aries, 2,504 years before Christ, and with the first degree of Taurus 4,619 years before Christ. Now it is to be observed, that the worship of the Bull is the principal article in the theological creed of the Egyptians, Persians, Japanese, etc.; from whence it clearly follows, that some general revolution took place among these nations at that time. The chronology of five or six thousand years in Genesis is little agreeable to this hypothesis; but as the book of Genesis cannot claim to be considered as a
