Each of the twelve signs (thirty degrees on the arc of the heavens) was divided into three "faces" (ten degrees). The position of the planet was most auspicious when in the first face of the house; if in the third its favorable influence was doubtful. As the reader will see from the first table given above, the signs of the Zodiac were supposed to sustain a relation to the elements and to temperaments. Aries, Leo and Sagittarius were warm, dry, fiery and choleric. Mars entering these signs--excepting that of Aries which was his own house, in which he was auspicious--must therefore bode draught, conflagration and pestilence. Taurus, Virgo and Capricornus, were cold, dry, earthy, melancholic. Saturn in the second sign of Taurus might consequently betoken a severe winter. The signs of Cancer, Scorpio and Pisces were cold, damp, watery and sanguine. The dominion of the Zodiacal constellations over the human body was divided as follows: Aries presided over the head and face, Taurus over the neck and throat, Gemini over the shoulders, arms and hands, Cancer over the breast, ribs, lungs and spleen, Leo over the upper part of the stomach, back and side, Virgo over the lower part of the stomach and intestines, Scorpio over the generative organs, Sagittarius over the anus, Capricornus over the knees, Aquarius over the thighs, Pisces over the feet. The planets exercised the same influence as their houses, and all elementary things subordinated to a planet were considered to be, during auspicious aspects, excellent remedies for affections in the limbs presided over by that planet. The series of analogies, of which we have given an example above, were therefore inexhaustible mines even for the physicians of the Middle Ages. Since, for instance, Capricornus which presided over the knees, is the house of Saturn, and all crawling animals are connected with this planet, the fat of snakes is an effective remedy against gout in the knees, especially on Saturday, the day of Saturn. [34] The days bear yet, in many languages, the names of the planets which were assigned to them in gray antiquity by Astrology. Sunday, dies Solis, is the day of the Sun. Monday, dies Lunæ, is the day of the Moon. Tuesday, dies Martis, is the day of Mars, _i. e._, Tiw. Wednesday, dies Mercurii, is the day of Mercury. Thursday, dies Jovis, is the day of Jupiter, _i. e._, Thor. Friday, dies Veneris, is the day of Venus, _i. e._, Freja. Saturday, dies Saturni, is the day of Saturn.
