Colours were also assigned to the twelve zodiacal signs—to Aries, white and red; to Taurus, white and lemon; to Gemini, white and red (the same as Aries); to Cancer, green or russet; to Leo, red or green; to Virgo, black speckled with blue; to Libra, black, or dark crimson, or tawny colour; to Scorpio, brown; to Sagittarius, yellow, or a green sanguine (this is as strange a colour as the gris rouge of Molière's L'Avare); Capricorn, black or russet, or a swarthy brown; to Aquarius, a sky-coloured blue; to Pisces, white glistening colour (like a fish just taken out of the water).

The chief fixed stars had various influences assigned to them by astrologers. These influences were mostly associated with the imaginary figures of the constellations. Thus the bright star in the head of Aries, called by some the Ram's Horn, was regarded as dangerous and evil, denoting bodily hurts. The star Menkar in the Whale's jaw denoted sickness, disgrace, and ill-fortune, with danger from great beasts. Betelgeux, the bright star on Orion's right shoulder, denoted martial honours or wealth; Bellatrix, the star on Orion's left shoulder, denoted military or civic honours; Rigel, on Orion's left foot, denoted honours; Sirius and Procyon, the greater and lesser Dog Stars, both implied wealth and renown. Star clusters seem to have portended loss of sight; at least we learn that the Pleiades were 'eminent stars,' but denoting accidents to the sight or blindness, while the cluster Præsepe or the Beehive in like manner threatened blindness. The cluster in Perseus does not seem to have been noticed by astrologers. The variable star Algol or Caput Medusæ, which marks the head of Gorgon, was accounted 'the most unfortunate, violent, and dangerous star in the heavens.' It is tolerably clear that the variable character of this star had been detected long before Montanari (to whom the discovery is commonly attributed) noticed the phenomenon. The name Algol is only a variation of Al-ghúl, the monster or demon, and it cannot be doubted that the demoniac, Gorgonian character assigned to this star was suggested by its ominous change, as though it were the eye of some fierce monster slowly winking amid the gloom of space. The two stars called the Aselli, which lie on either side of the cluster Præsepe, 'are said' (by astrologers) 'to be of a burning nature, and to give great indications of a violent death, or of violent and severe accidents by fire.' The star called Cor Hydræ, or the serpent's heart, denotes trouble through women (said I not rightly that Astrology was a masculine science?); the Lion's heart, Regulus, implied glory and riches; Deneb, the Lion's tail, misfortune and disgrace. The southern scale of Libra meant bad fortune, while the northern was eminently fortunate.

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.

Not only do the names remain, but some of the observances connected with the old astrological systems remain even to this day. As ceremonies derived from Pagan worship are still continued, though modified in form, and with a different interpretation, in Christian and especially Roman Catholic observances, so among the Jews and among Christians the rites and ceremonies of the old Egyptian and Chaldæan astrology are still continued, though no longer interpreted as of yore. The great Jewish Lawgiver and those who follow him seem, for example, to have recognised the value of regular periods of rest (whether really required by man or become a necessity through long habit), but to have been somewhat in doubt how best to continue the practice without sanctioning the superstitions with which it had been connected. At any rate two different and inconsistent interpretations were given in the earlier and later codes of law. But whether the Jews accepted the Sabbath because they believed that an All-powerful Being, having created the world in six days, required and took rest ('and was refreshed') on the seventh, as stated in Exodus (xx. 11 and xxxi. 17), or whether they did so in remembrance of their departure from Egypt, as stated in Deuteronomy (v. 15), there can be no question that among the Egyptians the Sabbath or Saturn's day was a day of rest because of the malignant nature of the powerful planet-deity who presided over that day. Nor can it be seriously doubted that the Jews descended from the old Chaldæans, among whom (as appears from stone inscriptions recently discovered) the very word Sabbath was in use for a seventh day of rest connected with astrological observances, were familiar with the practice even before their sojourn in Egypt. They had then probably regarded it as a superstitious practice to be eschewed like those idolatrous observances which had caused Terah to remove with Abraham and Lot from Ur of the Chaldees. At any rate, we find no mention of the seventh day of rest as a religious observance until after the Exodus.[15] It was not their only religious observance having in reality an astrological origin. Indeed, if we examine the Jewish sacrificial system as described in Numbers xxviii. and elsewhere, we shall find throughout a tacit reference to the motions or influences of the celestial bodies. There was the morning and evening sacrifice guided by the movements of the sun; the Sabbath offering, determined by the predominance of Saturn; the offering of the new moon, depending on the motions of the moon; and lastly, the Paschal sacrifice, depending on the combined movements of the sun and moon—made, in fact, during the lunation following the sun's ascending passage of the equator at the sign of Aries.

Let us return, however, after this somewhat long digression, to astrological matters.
