Magic was, in ancient times, a favourite study among the learned. Plato, Pythagoras, and other men of note, travelled over many countries to learn this art. After studying for a long time, they publicly communicated the knowledge of magic to students from every quarter of the globe. The knowledge acquired by magicians, if real, was wonderful. One discovered that, by tying a bull to a fig tree, the animal, though of a furious nature, instantly became subdued. The same authority states that, by hanging an old tough fowl on the same description of tree, it would become tender. Another professor of magic taught that the feathers of an eagle, mixed with those of other birds, would consume them, and that a small fish called Remora could stop the progress of a ship at sea. Magicians supplied precious stones to public speakers, the possession of which made them eloquent, and brought them into favour with princes. A certain gem carried in a husband's pocket made him love his wife, and enabled him to overcome his enemies. Coral was a preventative against witchcraft, hence the fashion of ladies and children wearing necklaces and bracelets of this material. Hyacinth brought down rain, obscured the sun, and preserved from lightning. One stone resisted drunkenness, so that the bearer could be able to drink freely without becoming intoxicated. A chalcedony made the wearer lucky at law, increased the vigour of one's body, and prevented illusions of the devil. Those acquainted with magical art concluded that all stones possessed virtues, infused into them by the influence of planets. Alexander, Hermes, Zoroaster, and several other ancients, entertained this opinion. Magicians were the first to set stones in rings—an invention which, if not beneficial to man and woman, has helped to adorn their persons.

Gems used for magical purposes required to be set in such metals as had affinity with the planets whereby they (the gems) were influenced. The image of Saturn should be made in lead; of Sol, in gold; of Luna, in silver; of Jupiter, in tin; of Mars, in iron; of Venus, in copper; of Mercury, in quicksilver. A proper time should be observed for the graving of magical figures. If love is to be procured, the graving must be done under proper and friendly aspects, as in the hour of Venus. Such signs as ascend in the day must be taken in the day. If they increase in the night, then the work must be done in the night. Wise men tell us that an olive planted by a virgin will thrive, but if by an unchaste woman it will wither. If a serpent be found in a hole, it may be safely pulled out by the left hand, but to attempt to do so with the right would be dangerous.

Learned writers on magic say that if one take a new knife, and cut a lemon with it while the operator is expressing words of hatred or dislike against a person he or she may wish evil to, the object of hatred will feel uneasy, and become unwell. If a live pigeon be cut through the heart while an evil wisher is venting curses against a friend or neighbour, the individual against whom the evil wishes are made will suffer in body and mind. A man will be put in great fear if his image, prepared according to the arts of magic, be suspended by a single hair or thread, however far distant he may be from the scene of operation. If a person suffering from toothache or asthma catch a live frog before sunrise, and spit into its mouth, immediate relief will be the result. If the plague or any epidemic disease threaten a village or town, the disorder will be stayed by a live toad being suspended for three or four days in a chimney. The dried body of a dead toad, worn in the breast, prevents the possessor of the charm from being injured by any infectious disease. Hippocrates had great honours conferred on him on account of the cures he effected by the application of certain parts of reptiles to disordered persons. The heart of a toad, suspended by a blue ribbon round the neck, will cure the king's evil. Rape seed, sown with cursing and imprecation, grows better, we are told, than when the seed is blessed. If one wear a girdle of civet-cat skin in battle, he will escape unhurt. Those skilled in such secrets say they can be easily explained. In their arguments they point to the antipathy of certain natural things, animate and inanimate, to other things in nature. The wing of a bat and the heart of a lapwing repel evil spirits and wicked passions; the bustard flies off when a horse comes in sight, and the hart bounds away at the sight of a ram or viper; a lion trembles at the crowing of a cock. If one swallow the heart of a lapwing, mole, or weasel, taken from the animal when alive, it will improve his understanding, and enable him to prophesy.

Democritus says that if one cut the tongue out of a live frog, and lay it on a woman's breast opposite her heart, she will be compelled to answer every question put to her. Dogs will never attack a person that has a weasel's tail in his pocket or breast, provided the appendage has been severed from the little animal when it was alive. If one has a chameleon's tongue, cut out before the creature's death, he may defy all the sharpers in the world. If the blood of a civet-cat be sprinkled on the doors and windows of a house, witches and sorcerers will be prevented from entering it or molesting the inmates thereof. If an enemy desire to render any one hateful to friends and neighbours, it may be done by the touch of an ointment composed of the ashes of a calcined ankle-bone of a man, oil extracted from the left foot of the same body, and the blood of a weasel. Civet-cat gut tied round a man's left arm, makes all the ladies look on him with favour; and civet-cat skin worn as a cap, protects the wearer against the art of witches. If a stone that has been in a mad dog's mouth be put into ale handed round at a feast, discord will take place. If a bone taken from a toad's left side be secretly put into any part of a woman's dress, it will kindle her love into a burning flame; but if the corresponding bone of the toad's right side be used, the most ardent love of the woman will be cooled. If the snaffle of a bridle be made of a sword that has killed a man, the rider may with ease control a horse, however wild the animal may be; and if a sword that has been used in beheading a person be dipped in wine, it will impart a medicinal virtue to the liquor.

Pliny is accountable for a few of the foregoing and many other similar stories, all of which were believed at one time.

Fires kindled with human fat or oil frightens away evil spirits. On the other hand, vapours exhaled from certain suffumigations induce spirits to appear. The lungs of an ass, when burned, drive evil spirits away. Magicians say that if gold or silver be hid when the moon is in conjunction with the sun, and the place be perfumed with saffron, henbane, and black poppy, the treasure will never be feloniously carried away, for spirits will constantly watch over it. The blood of doves, lapwings, and bats possesses peculiar virtues—attracting spirits to places where they may be required to appear, and exciting love passions.

Magicians, when sacrificing to the planets with the view of securing their diabolical ends, throw into the flames such things as raise a pleasant perfume when they wish to perform good actions; but when they desire to bring about wicked results, they raise disagreeable smells. When soliciting the aid of the sun, it was customary to take the brain of an eagle or the blood of a white cock; when appealing to the moon, the blood of a goose was supposed to be good; when sacrificing to Saturn, the brain of a cat and the blood of a bat were indispensable; when soliciting Jupiter's assistance, the blood of a swallow or stork and the brains of a hart were recommended; when sacrificing to Mars, the blood of a man or of a black cat was thought best; and when Mercury was sacrificed to, the brain of a fox or of a weasel and the blood of a magpie were burned on the altar.

All instruments, vessels, and other things used for magical purposes were recommended to be new; and when a magical missive was to be written, the parchment was prepared from the skin of a black kitten, the pen was a feather plucked from a live crow or raven, and the ink consisted of human blood, or a preparation of calcined cuttle-fish bones, nutgalls, and rain water, prepared in the day and hour of Saturn.

In order to secure success in the magical art, it was necessary for the operator to have his whole soul in his work, otherwise his labour was in vain. Ancient philosophers have informed us that when the human mind is intent upon magical work, it is joined with the mind and intelligence of the stars, and hence the wonderful result of secret art.

Magicians pretended to possess the power of producing monstrous creatures, even devils. They could, if their statements can be relied upon, create a cockatrice by artificially hatching an egg in a preparation of arsenic and the poison of serpents. The ashes of a burned duck, treated in a magical manner, produced a huge toad. Numerous writers conclude that there are two species of toads—the one produced by ordinary generation, and the other by devilish science. Plutarch and more modern writers say that frogs descend from the clouds in rain. Egyptian magicians produced proof of mice, frogs, and serpents growing out of earth and flowers. It was said that Damnatus Hispanus could make them in any number he pleased.

By certain charms, magicians could place a horse or an ass's head upon a man's shoulders, and change the head of an inferior animal into that of a human pate.

Magicians attached great importance to their circles. One of the fraternity, when about to proceed with his secret art, clothed himself with a black robe reaching to the knee, and under that a white garment of fine linen. He then took his position in the centre of the place where he intended to perform his conjurations, and, throwing his old shoes about ten yards from the circle, put on consecrated sandals with curious figures on each. (Here we may observe that not a few antiquarians are of opinion that from these practices arose the custom of persons throwing old shoes after newly-wedded pairs and others for luck, and of shoemakers making fanciful outlines on shoes by means of pegging and stitching.) With a magical wand of hazel the magician stretched forth his arm to the four winds, turning himself round to every wind, and beseeching his "master" to consecrate the circle. All these ceremonies being performed, he claimed the consecrated ground as a defence from all malignant spirits, that they might not have power over his soul or body.

The most suitable time for making circles was during bright moonlight, or when storms of wind or thunder were raging, because then the infernal spirits were nearer the earth than at other times, and could more easily hear the invocations of those who sought their assistance. Magical circles were recommended to be formed at dark lonely places—either in woods or deserts, or in places where three ways met, or among ruins of castles, abbeys, or monasteries, or on the sea-shore. But if the conjuration was to raise the ghost of one deceased, the fittest places for the purpose were spots where persons had been slain, woods in which suicides had been committed, churchyards, and burying-vaults. If any one doubts the correctness of what is here stated, perhaps he will change his mind after reading the following story:—

"A certain hangman, passing the image of our Lady, saluted her, and commended himself to her protection. Afterwards, while he prayed before her, he was called away to hang an offender, but his enemies slew him by the way. And lo! a certain priest, who walked nightly about every church in the city, rose that night to go to our Lady's church. In the churchyard he saw the ghosts of many dead men. On demanding what was the matter, he was told that the hangman was slain, and that the devil demanded his soul, but which our Lady said was hers, and that the judges were at hand to hear the cause. The priest having made up his mind to be at the trial, hid himself behind a tree. When the judges had taken their seats, the hangman was brought forward pinioned, and proof adduced that his soul belonged to the devil. On the other side it was pleaded by our Lady, that at the hour of death the hangman commended his soul to her. The judges gave sentence that the hangman's soul should return to his body until he made sufficient satisfaction. The priest was called from his hiding-place and sent to the Pope with a rose of rare beauty, and instructions to crave the prayers of his Holiness for the poor man." Although we are not made acquainted with the result of the application to the Pope, there can be little doubt but that, through our Lady and his Holiness, Satan lost his eagerly desired victim.

Directions are given by the learned how to raise ghosts and evil spirits. To raise the ghost of one who had hanged himself, the exorcist was to provide himself with a straight hazel wand, and bind the head of an owl with a bunch of St. John's-wort to the end thereof. This done, he was to repair to a place where a miserable wretch had strangled himself, and at twelve o'clock at night, while the body remained suspended, begin his conjurations. First, he was directed to stretch forth his wand towards the four corners of the world, saying, "I conjure and exorcise thee, thou distressed spirit, to present thyself here and reveal unto me the cause of thy calamity—why thou didst offer violence to thine own life, where thou art now in being, and where thou wilt hereafter be?" Then, gently striking the body nine times with the wand, he was to demand the spirit of the deceased to reveal unto him what secrets he wished made known, whether these referred to the past or future. The conjuration being thrice repeated, we are assured the spirit would rise and answer the exorcist's questions. Directions were next given for laying the spirit, and that might be done by burying the body naked with lime, salt, and sulphur. If the ghost which the exorcist consulted was of one who died a common death, and received the usual burial, it was essential to dig the body out of the grave at twelve o'clock at night; and while the exorcist held a torch in his left hand, he was to smite the corpse three times with his consecrated rod, held in the right hand, and demand answers to his questions. When the ceremonies were gone through in a regular way, the interrogatories were truly answered. A caution was offered to the practiser of this art. The magician of no great experience was told that if the constellation and position of the stars at his nativity were not favourable, it would be dangerous for him to encounter a ghost for fear of being slain, as the ghosts of men could easily destroy magicians not protected by the stars.

Magicians were instructed how to raise the spirits Paymon, Bathin, and Barma, and secure their assistance. These spirits, though of various ranks and orders, were of one power, ability, and nature, and the mode of raising them is the same. The magician who desired to consult with these spirits had to appoint a night in the waxing of the moon, when the planet Mercury reigned, at eleven o'clock at night. But for four days before the appointed night he was required to shave his beard every morning, change his linen, and put on a consecrated girdle made of a black cat's skin. When all was prepared for the summoning of the spirits, the magician was instructed to enter a dark parlour or cellar, to light seven candles, and draw a circle with his own blood. When the candles were lighted, it was essential for the magician to protect himself with two drawn swords, and consecrate the circle, so that all evil spirits might be expelled. Everything being ready, the conjuration commenced in these words: "I conjure and exorcise you, the three gentle and noble spirits of the power of the north, by the great and dreadful name of your king, and by the silence of the night, and by the holy rites of magic, and by the number of the infernal legions, I adjure and advocate you that without delay ye present yourselves here before the northern quarter of the circle, all of you, or any one of you, and answer my demands." This, we are informed, had to be repeated three times, and then the three spirits appeared, or one of them by lot, if the others were engaged elsewhere. Before their appearance, they sent in advance three swift hounds in pursuit of a hare, which ran round the circle for seven and a half minutes. After this chase more hounds came in, and after all a little ugly Ethiopian, who snatched the hare from the hounds. Next was heard a hunter's horn, and a herald on horseback came galloping swiftly with three hunters behind him upon black horses. After riding round the circle seven times, they stood at the northern quarter. The magician then demanded the demons to be faithful and obedient, which they readily agreed to be. Valuable information was obtained from the spirits, who gave the magician the powerful girdle of victory, which, on being tied about him, enabled him to conquer armies, and all men, however powerful. The spirits also were compelled to bring, at the magician's bidding, the richest treasure earth could afford, and to reveal the positions of hidden gold and silver mines.

The spirits could bestow the gift of invisibility, and the foreknowledge of the change of the weather; they could teach the exorcist how to raise storms and tempests, and how to calm them again; they could bring news in an instant of the result of any battle or other important event, wherever it took place. They could also teach the language of birds, and how to fly unseen through the air.
