The latter is more particularly the study of a primitive age; when the mind, incapable of arriving at the stupendous fact that the myriads of minute lights glowing in the firmament are the centres of systems as glorious as our own, is naturally led to speculate on their probable uses, and to connect them in some way or other with man, for whose convenience every other object in the universe seems to have been created. As the eye of the simple child of nature watches, through the long nights, the stately march of the heavenly bodies, and sees the bright hosts coming up, one after another, and changing with the changing seasons of the year, he naturally associates them with those seasons, as the periods over which they hold a mysterious influence. In the same manner, he connects their appearance with any interesting event of the time, and explores, in their flaming characters, the destinies of the new-born infant.[197] Such is the origin of astrology, the false lights of which have continued from the earliest ages to dazzle and bewilder mankind, till they have faded away in the superior illumination of a comparatively recent period. The astrological scheme of the Aztecs was founded less on the planetary influences than on those of the arbitrary signs they had adopted for the months and days. The character of the leading sign in each lunar cycle of thirteen days gave a complexion to the whole; though this was qualified in some degree by the signs of the succeeding days, as well as by those of the hours. It was in adjusting these conflicting forces that the great art of the diviner was shown. In no country, not even in ancient Egypt, were the dreams of the astrologer more implicitly deferred to. On the birth of a child, he was instantly summoned. The time of the event was accurately ascertained; and the family hung in trembling suspense, as the minister of Heaven cast the horoscope of the infant and unrolled the dark volume of destiny. The influence of the priest was confessed by the Mexican in the very first breath which he inhaled.[198]
