The necromancers, who were supposed to be able to conjure up spirits and raise the dead, were accounted on a somewhat higher plane than the interpreters of dreams. They also based their authority on the Old Testament. The nature of the art was gruesome and awe-inspiring, and there is little doubt many dark deeds were perpetrated by those who practised it. One method of evocation was to kill a child and place its head upon a dish surrounded by lighted candles; the desired spirit was supposed to enter this ghastly object and speak through its mouth. Sometimes the spirit simply consisted of some muttered words from behind a curtain in a dark cellar; another method was to cause the appearance of a sepulchral figure out of smoke or vapour, which would indicate by gesture and reply to questions asked. To evoke a dead man’s spirit, it was necessary to go to the grave at midnight with a companion who bore a candle in the left hand and a crystal stone in the right, the conjurer holding a hazel wand with the name of God written on it, and repeating the words:—

“Tetragrammaton + Adonai + Agla + Craton +”

Then striking three times on the ground, with a prayer he commanded the spirit into the stone, when it appeared in the shape of a child.

The conjurer often wore a girdle of lion’s skin with the name of God written on it, and the Solomon’s circle he described with a bright knife, on the blade of which were written certain mystic words. Necromancy gradually merged into sorcery, which has occasionally come to the surface in comparatively recent years.

Chiromancy, the art of divining or foretelling future events from marks on the palm of the hand, was also practised in antiquity, but in mediæval times it was strongly opposed by the Church. The practice is supposed to have been brought into Europe from the East by the Bohemians in the early part of the fifteenth century. This art eventually merged into astrology, which exerted the greatest influence of all the occult sciences.

The antiquity of astrology is very great, it having been originated by the Chaldeans, and was thought by some of the Jews to have been a method by which the Creator could communicate with His people. The art itself was based on astronomy, and, like alchemy, was the beginning of the study of real natural science. The teller of the stars was not only supposed to foretell forthcoming misfortunes to individuals, but also to forecast the destinies of kings and empires.

The belief in its power was so great that it became the fashion among royal personages of the sixteenth century to keep their own special astrologers, who were lodged easy of access and loaded with honours and wealth. These men were mostly astute Jews well versed in the science of their time, and by means of their supposed powers they often played a very important part in the political affairs of the nation. Thus in the fifteenth century Rovigo, an astrologer of eminence, who is said to have perfected the astrolabe, was attached to the Court of King John II. of Portugal; and Simon Pharès figured at the Court of France in the time of Charles VIII. We must not forget to mention Cosmo Ruggieri, the Florentine astrologer and the confidant of Catherine de Medicis; also the celebrated Nostradamus, astrologer and trusted adviser of Charles IX. This extraordinary man played a prominent part in the history of his time, and was supposed to practise magic and alchemy as well as the healing art. He was consulted by the king in all positions of difficulty, and it is said became immensely wealthy. He died in 1566 at Salon, after having written several notable works.

CHAPTER IX.
THE ART OF FORETELLING.

The early theory of the art of foretelling by means of the stars, and casting horoscopes, was as follows: The seven planets then known, including the Sun, with the twelve figures of the Zodiac, comprised the astrological system. Each unit or body or nation was supposed to be governed or influenced by a certain star or constellation, and this power extended to all things connected with the person or nation. Thus, Saturn was supposed to influence life, sciences, and buildings; Jupiter—honour, wishes, and wealth; Mars—wars, persons, marriages, and quarrels; the Sun—hope, gain, and happiness; Venus—love and friendship; Mercury—fear, disease, debts, and commerce; the Moon—robberies, wounds, and dreams. The intrinsic quality was denoted by the planet. The Sun was regarded as favourable; Saturn, cold; Jupiter, temperate; Mars, ardent; Venus, fruitful; Mercury, inconstant; the Moon, melancholy. The days, colours, and metals also came under the same influences.
