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.
