Mercury is considered by astrologers 'a cold, dry, melancholy star.' The Mercurial is neither dark nor fair, but between both, long-faced, with high forehead and thin sharp nose, 'thin beard (many times none at all), slender of body, and with small weak eyes;' long slender hands and fingers are 'especial marks of Mercury,' says Raphaël. In character the Mercurial is busy and prattling. But when well affected, Mercury gives his subjects a strong, vigorous, active mind, searching and exhaustive, a retentive memory, a natural thirst for knowledge.13 The persons signified by Mercury are astrologers, philosophers, mathematicians, politicians, merchants, travellers, teachers, poets, artificers, men of science, and all ingenious, clever men. When he is ill affected, however, he represents pettifoggers, cunning vile persons, thieves, messengers, footmen, and servants, etc.
The moon comes last in planetary sequence, as nearest to the earth. She is regarded by astrologers as a cold, moist, watery, phlegmatic planet, variable to an extreme, and, like the sun, partaking of good or evil according as she is aspected favourably or the reverse. Her natives are of good stature, fair, and pale, moon-faced, with grey eyes, short arms, thick hands and feet, smooth, corpulent and phlegmatic body. When she is in watery signs, the native has freckles on the face, or, says Lilly, 'he or she is blub-cheeked, not a handsome body, but a muddling creature.' Unless the moon is very well aspected, she ever signifies an ordinary vulgar person. She signifies sailors (not as Mars does, the fighting-men of war-ships, but nautical folk generally) and all persons connected with water or any kind of fluid; also all who are engaged in inferior and common offices.
We may note, in passing, that to each planet a special metal is assigned, as also particular colours. Chaucer, in the Chanones Yemannes' Tale, succinctly describes the distribution of the metals among the planets:—
Sol gold is, and Luna silver we threpe;
Mars iren, Mercurie silver we clepe:
Saturnus led, and Jupiter is tin,
And Venus coper, by my [the Chanones Yemannes'] faderkin.
The colours are thus assigned:—to Saturn, black; to Jupiter, mixed red and green; to Mars, red; to the sun, yellow or yellow-purple; to Venus, white or purple; to Mercury, azure blue; to the moon, a colour spotted with white and other mixed colours.
Again, the planets were supposed to have special influence on the seven ages of human life. The infant, 'mewling and puking in the nurse's arms,' was very appropriately dedicated to the moist moon; the whining schoolboy (did schoolboys whine in the days of good Queen Bess?) was less appropriately assigned to Mercury, the patron of those who eagerly seek after knowledge: then very naturally, the lover sighing like furnace was regarded as the special favourite of Venus. Thus far the order has been that of the seven planets of the ancient astrology, in supposed distance. Now, however, we have to pass over the sun, finding Mars the patron of mid life, appropriately (in this respect) presiding over the soldier full of strange oaths, and so forth; the 'justice in fair round belly with good capon lined' is watched over by the respectable sun; maturer age by Jupiter; and, lastly, old age by Saturn.
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,
