In the sixteenth century, Fernel, who, inasmuch as he was a mathematician and an astronomer, published his Cosmotheria, where he indicated the means of measuring a meridian degree with exactitude; his remarkable works on physiology (De naturali parte medicinæ, 1542), on pathology and therapeutics, which gave him the nickname of the French Galen. Fernel fully admitted the action of evil spirits on the body of man; he believed that adorers of the Demons could, by the aid of imprecations, enchantments, invocations and talismans, draw fallen angels into the bodies of their enemies, and that these Demons could then cause serious sickness. He compared the possessed to maniacs, but that the former had the gift of reading the past and divining the most secret matters. He affirmed that he had been witness of a case of delirium caused by the presence of the Devil in a patient, that which was denied by several doctors at the epoch.[61] He also believed in lycanthropy.... In the same century, another of our medical glories, Ambroise Pare, the Father of French surgery, also adopted the theory of the Inquisitors regarding sorcery in his works,[62] in which may be found his remarkable anatomical and surgical discoveries. We read the following quaintly conceived passage: “Demons can suddenly change themselves into any form they wish; one often sees them transformed into serpents, frogs, bats, crows, goats, mules, dogs, cats, wolves, and bulls; they can be transmuted into men as well as into angels of light; they howl in the night and make infernal noises as though dragging chains, they move chairs and tables, rock cradles, turn the leaves of books, count money, throw down buckets, etc., etc. They are known by many names, such as cacodemons, incubi, succubi, coquemares, witches, hobgoblins, goblins, bad angels, Satan, Lucifer, etc.
“The actions of Satan are supernatural and incomprehensible, passing human understanding, and we can no more understand them than we can comprehend why the loadstone attracts the needle. Those who are possessed by demons can speak with the tongue drawn out of their mouth, through the belly and by other natural parts; they speak unknown languages, cause earthquakes, make thunder, clear up the weather, drag up trees by the roots, move a mountain from one place to another, raise castles in the air and put them back in their places without injury, and can fascinate and dazzle the human eye.
“Incubi are demons in the disguise of men, who copulate with female sorcerers; succubi are demons disguised as women, who practice vile habits not only on sleeping, but wakeful men.”
“Ambroise Pare,” says Calmeil, “believed that demons hoarded up all kinds of foreign bodies in their victims’ persons, such as old netting, bones, horse-shoes, nails, horsehair, pieces of wood, serpents, and other curious odds and ends, and cites the wellknown case of Ulrich Neussersser.”
The celebrated surgeon concludes from this that “it was the Devil who made the iron blades and other articles found in the stomach and intestines of the unfortunate Ulrich.”
What would Pare have thought had he seen the strange objects so commonly found by modern surgeons in ovarian cysts? How many demons would it take to produce the numerous objects noticed at the present day?
Happily these demonological physicians accepted purely and simply the suggestion that demons could act on men, and abandoned the victims to the tender mercy of the theologians and their tools the lawyers. Yet, even in this time of atrocities there were a few courageous physicians who struggled for humanity as against ecclesiastical despotism. Let us quote, according to Calmeil, one Francoise Ponzinibus, who destroyed one by one all the arguments that served to support the criminal code against demons. It was this brave doctor who dared to write that demonidolatry constituted a true disease; that all the sensations leading the ignorant to believe in spirits who adored the Devil were due to a depraved moral and physical condition; that it was false that certain persons could isolate their souls from their bodies at night and thus leave their homes for far off places inhabited by demons; that the accouplement of sorcerers and all the crimes attributed to them could not be logically supposed but must be legally proven; that it was cruel and atrocious to burn demented people at the stake for witchcraft.
Let us also quote from Andre Alciat, another courageous physician, who dared accuse an Inquisitor of murdering a multitude of insane people on the plea of witchcraft. He considered the vigil (sabbat) of sorcerers as an absurd fiction, and saw in so-called possessed only so many poor demented women given over to fanatical delusions and wild dreams.
Paul Zacchias, the author of “Medico-Legal Questions” (Questiones Medico-legales), a work in which he shows himself to be as wise an alienist as Doctor of Laws. The avowed and open enemy of supernaturalism, he boldly denounced the cruelties committed against the demented.
Let us finally inscribe on the roll of honor, with our respects, the name of Jean Wier,[63] or rather of Joannes Wierus, physician to the Duke of Cleves, who studied in Paris, where he received the degree of doctor, and was afterwards the disciple of Cornelius Agrippa, a partisan of demonology. Like the latter, Jean Weir believed in astrology, alchemy, the cabala, sorcerers and female mediums; likewise in demons who possessed control of human beings through magic power. But in his works that he published in 1560 he proclaims the innocence of those unfortunates punished for witchcraft, and declares them to have been insane and melancholic; likewise asserting that they could have been cured by proper treatment. He declares that he is fully persuaded that sorcerers, witches, and lycanthropic patients who were burned at the stake were crazy people whose reason had been overthrown; and that the faults imputed to these unfortunates were dangerous to none but themselves; that the possessed were dupes to false sensations that had been experienced during the time of their ecstatic transports or in their sleep.
