Thus are dissipated for ever the conclusions which people had drawn from some ill explained monuments, against the newness of the continents and nations; and we might have dispensed with treating of them so much in detail had they not been so recent, and had they not made sufficient impression still to retain their influence over the minds of some individuals. _The Zodiac is far from bearing in itself a certain and excessively remote date._ But there are writers who have maintained that the zodiac bears in itself the date of its invention, because the names and figures given to its constellations are an index of the position of the colures at the time when it was invented; and this date, according to several, is so evident and so remote, that it is quite a matter of indifference whether the representations which we possess of this circle are more or less ancient. They do not attend to the circumstance that, in this sort of argument, there is a complication of three suppositions equally uncertain: the country in which the zodiac is presumed to have been invented, the signification which is supposed to have been given to the constellations which occupy it, and the position in which the colures were with relation to each constellation, when this signification was attributed to it. According as other allegories have been imagined, or as these allegories are admitted to have referred to the constellation of which the sun occupied the first degrees, or to that of which it occupied the middle, or to that into which it began to enter, that is to say, of which it occupied the last degrees; or, lastly, to that which was opposite to him, and which rose at night; or according as the invention of these allegories is placed in a different climate, must the date of the zodiac also be changed. The possible variations in this respect might comprehend so much as the half of the revolution of the fixed stars, that is to say, 13,000 years, and even more.
