Astrology was divided into three distinct branches—the doctrine of nativities, horary astrology, and state astrology. The first assigned the rules for determining the general fortunes of the native, by drawing up his scheme of nativity or casting his horoscope. It took into account the positions of the various planets, signs, stars, etc., at the time of the native's birth; and as the astrologer could calculate the movements of the planets thereafter, he could find when those planets which were observed by the horoscope to be most closely associated with the native's fortunes would be well aspected or the reverse. Thus the auspicious and unlucky epochs of the native's life could be predetermined. The astrologer also claimed some degree of power to rule the planets, not by modifying their movements in any way, but by indicating in what way the ill effects portended by their positions could be prevented. The Arabian and Persian astrologers, having less skill than the followers of Ptolemy, made use of a different method of determining the fortunes of men, not calculating the positions of the planets for many years following the birth of the native, but assigning to every day after his birth a whole year of his life and for every two hours' motion of the moon one month. Thus the positions of the stars and planets, twenty-one days after the birth of the native, would indicate the events corresponding to the time when he would have completed his twenty-first year. There was another system called the Placidian, in which the effects of the positions of the planets were judged with sole reference to the motion of the earth upon her axis. It is satisfactory to find astrologers in harmony amongst each other as to these various methods, which one would have supposed likely to give entirely different results. 'Each of them,' says a modern astrologer, 'is not only correct and approved by long-tried practice, but may be said to defy the least contradiction from those who will but take the pains to examine them (and no one else should deliver an opinion upon the subject). Although each of the above methods are different, yet they by no means contradict each other, but each leads to true results, and in many instances they each lead to the foreknowledge of the same event; in which respect they may be compared to the ascent of a mountain by different paths, where, although some paths are longer and more difficult than others, they notwithstanding all lead to the same object.' All which, though plausible in tone labours under the disadvantage of being untrue.
Ptolemy is careful to point out, in his celebrated work the 'Tetrabiblos,' that, of all events whatsoever which take place after birth, the most essential is the continuance of life. 'It is useless,' he says, 'to consider what events might happen to the native in later years if his life does not extend, for instance, beyond one year. So that the enquiry into the duration of life takes precedence of all others.' In order to deal properly with this question, it is necessary to determine what planet shall be regarded as the Hyleg, Apheta, or Lord of Life, for the native. Next the Anareta, or Destroyer of Life, must be ascertained. The Anaretic planets are, by nature, Saturn, Mars, and Uranus, though the sun, moon, and Mercury may be endowed with the same fatal influence, if suitably afflicted. The various ways in which the Hyleg, or Giver of Life, may be afflicted by the Anareta, correspond to the various modes of death. But astrologers have always been singularly careful, in casting horoscopes, to avoid definite reference to the native's death. There are but few cases where the actual day of death is said to have been assigned. One is related in Clarendon's 'History of the Rebellion.' He tells us that William Earl of Pembroke died at the age of fifty, on the day upon which his tutor Sandford had predicted his decease. Burton, the author of the 'Anatomy of Melancholy,' having cast his own horoscope, and ascertained that he was to die on January 23, 1639, is said to have committed suicide in order that the accuracy of his calculations might not be called in question. A similar story is related of Cardan by Dr. Young (Sidrophel Vapulans), on the authority of Gassendi, who, however, says only that either Cardan starved himself, or, being confident in his art, took the predicted day for a fatal one, and by his fears made it so. Gassendi adds that while Cardan pretended to describe the fates of his children in his voluminous commentaries, he all the while never suspected, from the rules of his great art, that his dearest son would be condemned in the flower of his youth to be beheaded on a scaffold, by an executioner of justice, for destroying his own wife by poison.
Horary astrology relates to particular questions, and is a comparatively easy branch of the science. The art of casting nativities requires many years of study; but horary astrology 'may be well understood,' says Lilly, 'in less than a quarter of a year.' 'If a proposition of any nature,' he adds, 'be made to any individual, about the result of which he is anxious, and therefore uncertain whether to accede to it or not, let him but note the hour and minute when it was first made, and erect a figure of the heavens, and his doubts will be instantly resolved. He may thus in five minutes learn whether the affair will succeed or not: and consequently whether it is prudent to accept the offer made or not. If he examine the sign on the first house of the figure, the planet therein, or the planet ruling the sign, will exactly describe the party making the offer, both in person and character, and this may at once convince the enquirer for truth of the reality of the principles of the science. Moreover, the descending sign, etc., will describe his own person and character—a farther proof of the truth of the science.'
There is one feature of horary astrology which is probably almost as ancient as any portion of the science, yet which remains even to the present day, and will probably remain for many years to come. I refer to the influence which the planets were supposed to exert on the successive hours of every day—a belief from which the division of time into weeks of seven days unquestionably had its origin—though we may concede that the subdivision of the lunar month into four equal parts was also considered in selecting this convenient measure of time. Every hour had its planet. Now dividing twenty-four by seven, we get three and three over; whence, each day containing twenty-four hours, it follows that in each day the complete series of seven planets was run through three times, and three planets of the next series were used. The order of the planets was that of their distances, as indicated above. Saturn came first, then Jupiter, Mars, the Sun, Venus, Mercury, and the Moon. Beginning with Saturn, as ruling the first hour of Saturn's day (Saturday), we get through the above series three times, and have for the last three hours of the day, Saturn, Jupiter, and Mars. Thus the next hour, the first hour of the next day, belongs to the sun—Sunday follows Saturday. We again run three times through the series, and the three remaining hours are governed by the sun, Venus, and Mercury—giving the moon as the first planet for the next day. Monday thus follows Sunday. The last three hours of Monday are ruled by the moon, Saturn, and Jupiter; leaving Mars to govern the next day—Martis dies, Mardi, Tuesday or Tuisco's day. Proceeding in the same way, we get Mercury for the next day, Mercurii dies, Mercredi, Wednesday or Woden's day; Jupiter for the next day, Jovis dies, Jeudi, Thursday or Thor's day; Venus for the next day, Veneris dies, Vendredi, Friday or Freya's day; and so we come to Saturday again.[14]
The period of seven days, which had its origin in, and derived its nomenclature from astrological ideas, shows by its wide prevalence how widely astrological superstitions were once spread among the nations. As Whewell remarks (though, for reasons which will readily be understood he was by no means anxious to dwell upon the true origin of the Sabbatical week), 'the usage is found over all the East; it existed among the Arabians, Assyrians, and Egyptians. The same week is found in India, among the Brahmins; it has there also its days marked by the names of the heavenly bodies; and it has been ascertained that the same day has, in that country, the name corresponding with its designation in other nations. … The period has gone on without interruption or irregularity from the earliest recorded times to our own days, traversing the extent of ages and the revolutions of empires; the names of ancient deities, which were associated with the stars, were replaced by those of the objects of the worship of our Teutonic ancestors, according to their views of the correspondence of the two mythologies; and the Quakers, in rejecting these names of days, have cast aside the most ancient existing relic of astrological as well as idolatrous superstition.
