Illustrations of Belief in Magic in Mediæval and in Early Modern
Times
Evena slight acquaintance with European history
reveals the existence of a number of curious and apparently
unreasonable beliefs prevalent throughout a period extending from
early mediæval to comparatively recent times. There is the belief
in witchcraft, for instance. From the canons of synods in the early
Middle Ages down to the pitiless executions during the witchcraft
delusion, there is abundant evidence of its prominence. It played
its part not only in humble life, but in court intrigues and in the
accusations brought at state trials.The belief that one's future could be learned by observing
the stars was equally widespread. Astrologers throve at the courts
of kings, and sometimes their advice was taken even by him whose
every act was held to be under special divine direction. It would
be a great mistake to think that the astrologer was maintained
merely for the amusement of king and court, like the jester. His
utterances were taken most seriously, and the principles of his art
were so generally accepted as to become the commonplaces of the
thought and the conversation of daily life. In 1305, for instance,
when certain cardinals urged Pope Clement V to return to Rome, they
reminded him that every planet was most powerful in its own
house.[1]Indeed, even in our speech
to-day numerous vestiges of the astrological art survive.[2]Moreover, a grander and more imposing witchcraft displayed
itself in the stories of the wizard Merlin and in the persons of
the wicked magicians with whom knights contended in the pages of
mediæval romance. So strong was the tendency to believe in the
marvelous, that men of learning were often pictured by subsequent
tradition, if not by contemporary gossip, as mighty necromancers.
Even Gerbert, who seems to have done nothing more shocking than to
write a treatise on the abacus and build a pipe-organ, was pictured
as running off with a magician's book and daughter, hanging under
bridges between earth and water to escape noxious spells, and
making compacts with Satan.[3]The attitude of the average mind as it has just been
illustrated was to a large extent characteristic of the best
instructed and most widely read men. The erudite poet Dante
accepted the influence of the constellations upon human destiny.
Bodin maintained in hisRepublic—perhaps the
greatest book on political science written during the sixteenth
century—that astrology was very useful in tracing the development
of society.[4]Aquinas, chief of the
mediæval theologians, accepted astrological theory, except as
limited by human free will, and further admitted that most men make
little use of their liberty of action but blindly follow their
passions, which are governed by the stars.[5]Among other great mediæval churchmen and canonists, d'Ailly
and Gerson both believed that God signified important events in
advance through the stars, and d'Ailly made some astrological
predictions himself. Astrology was much taught in the mediæval
universities,[6]and was regarded as the
climax of mathematics and as an essential part of
medicine.It is with such beliefs, accepted by educated men and forming
a part of the learning and science of the times, that we are
concerned in this essay. First, it is necessary to give some
further evidence of the nature and of the general acceptance of
these beliefs. This object will be most quickly and effectively
secured by a résumé of the views of a few of the men most prominent
in the intellectual history of the past. These men should offer
fair, if not flattering, illustrations of the learning and culture
of their times. In especial we shall notice the curious notions of
those who wrote on scientific subjects or showed even a
considerable approach towards the modern scientific spirit. This we
shall do partly because their writings seem at first thought the
place where we should least expect to find such notions, and hence
furnish striking illustration of the almost universal acceptance of
these beliefs; partly because, as we shall soon find reason to
conclude, there is really some connection between such beliefs and
science.The early Middle Ages are not distinguished for the
prevalence of education and of culture in Latin Christendom, to say
nothing of profound knowledge or original thought in any particular
branch of learning. But in such learning and science as there was
may be found examples of the beliefs which we wish to consider. We
see them in Isidore of Seville, whoseEtymologies,we may well
believe, constituted an oft-consulted encyclopedia in many a
monastic library for several centuries after the seventh, when it
appeared. This saint, like almost all good Christians of his day,
believed that marvels could be effected through magic by the aid of
demons, although such resort to evil spirits he could not condemn
too strongly.[7]But he saw no harm in
holding that certain stones possess astonishing powers,[8]that the dog-star afflicts bodies with
disease, and that the appearance of a comet signifies pestilence,
famine or war.[9]He maintained that it
was no waste of time to look into the meaning of the numbers which
occur in the Bible. He thought that they might reveal many sacred
mysteries.[10]Bede expressed similar
views in his scientific treatises.[11]Also, if we may regard as his two little essays about the
authenticity of which there is some question, he ascribed such
extraordinary influence to the moon as to maintain that the
practice of bleeding should be regulated by its phases, and
wrote—with some hesitation lest he should be accused of magic—an
explanation of how to predict coming disasters by observing the
time and direction of peals of thunder.[12]Passing over several centuries during which judicial
astrology is very conspicuous in the mathematical treatises which
formed the greater part of the scientific literature of the
times,[13]we come at the close of the
twelfth century to theDe Naturis
Rerumof Alexander Neckam (1157-1217). We
find him ecstatically musing over the consonance of celestial
harmony and associating the seven planets with the seven liberal
arts and the seven gifts of the Holy Spirit,[14]as if believing that there is some occult
virtue in that number or some potent sympathy between these
material bodies and such abstractions as branches of learning and
generic virtues. Descending from the skies to things earthly—the
transition is easy since he believes in the influence, saving human
free will, of the planets on our lower creation[15]—he tells us that mugwort prevents the
traveler from feeling fatigue,[16]and
that the Egyptian fig makes the wrinkles of old age vanish and can
tame the fiercest bulls once they are gathered beneath its
branches.[17]He describes fountains
with properties as marvelous as those of the herb or of the
tree.[18]He tells of stones which,
placed on the head of the sleeping wife, provoke confession of
marital infidelity,[19]or which,
extracted from the crop of a rooster and carried in one's mouth,
give victory in war.[20]What is more,
words as well as plants and stones are found by the careful and
industrious investigator of nature to have great virtue, as
experiment shows beyond doubt.[21]Neckam, despite the fact that according to his editor, Thomas
Wright, he "not infrequently displays a taste for experimental
science,"[22]was, after all, more of a
moralizing compiler than anything else. But greater men than
Neckam, men who were interested in learning and science for their
own sake, men who knew more and wrote more, still cherished beliefs
of the same sort. There was Michael Scot in the early years of the
thirteenth century, the wonder of the cultured court of Frederick
II, perhaps that monarch's tutor, the "Supreme Master" of Paris,
the man who helped much to make the treasures of learning amassed
by the Arabs in Spain the common property of Latin Christendom, the
introducer to Western Europe of a Latin version of Averroes and of
an enlarged Aristotle.[23]Scot composed
a primer of astrology for young scholars. His writings on alchemy
show that he experimented in it not a little. HisPhysionomiaaccepts the
doctrine of signatures, tells us that these signs on the outward
body of the soul's inner state are often discovered through dreams,
and contains a chapter giving an extended description of the rules
of augury—an art on which the author, though a Christian,
apparently bestowed his sanction. Prophetic verses foretelling the
fate of several Italian cities have come down to us under his name.
A poem of Henri d'Avranches, written in 1235-6, recalls to mind the
fact that certain prophecies concerning the emperor had been made
by the then deceased Michael Scot, whom the poet proceeds to call a
scrutinizer of the stars, an augur, a soothsayer, averidicus vates, and a
second Apollo.[24]A most interesting
recipe for invoking demons to instruct one in liberal arts is
attributed to Michael Scot in a manuscript collection ofOccultain the Laurentian
library.[25]Later in the same century stands forth the famous figure of
Roger Bacon, the stout defender of mathematics and physics against
scholasticism. Some have ascribed to him numerous important
innovations in the realm of natural science and of the mechanical
arts, and have regarded his promulgation of the experimental
method, guided by the mathematical method, as the first herald note
of that modern science which was not destined really to appear for
yet several centuries. Yet he held that the alchemist, if given
sufficient time and money, could discover a way not only to meet
the state's expenses by converting baser metals into gold, but also
to prolong human existence beyond that limit to which it can be
drawn out by nature.[26]Indeed these
objects constituted two of the three examples he gave of the great
advantages to be gained from the pursuit of that experimental
science which was to disprove and blot out all magical
nonsense.[27]How far Bacon let the principles of astrology carry him a
citation or two will show. That a woman had succeeded in living
twenty years without eating was, he explained, no miracle, but due
to the fact that during that period some constellation was able to
reduce the concourse of the four elements in her body to a greater
degree of harmony than they usually attain.[28]Nor is it health alone that the stars
control; they affect human character.[29]They implant in the babe at birth good or evil dispositions,
great or small talents. Human free will may either better these
innate tendencies through God's grace or modify them for the worse
by yielding to Satan's temptings; but in general the stars so far
prevail that there are different laws and customs and national
traits under different quarters of the heavens.[30]Nay more, astrology offers proof of the
superiority of Christianity to other religions and gives insight
into the nature of Antichrist.[31]As one might surmise from Bacon's belief in the potent effect
of sidereal emanations, he makes much of the theory that every
agent sends forth its own virtue and species into external matter.
This leads him to accept fascination as a fact. Just as Aristotle
tells that in some localities mares become pregnant by the mere
odor of the stallions, and as Pliny relates that the basilisk kills
by a glance, so the witch by the vapor from her bleary eye draws
her victims on to destruction. In short, "Man can project virtue
and species outside himself, the more since he is nobler than all
corporeal things, and especially because of the virtue of the
rational soul."[32]Hence the great
effects possible from spoken words or written characters; although
one must beware of falling into the absurdities and abominations of
the magicians. Bacon, moreover, was like Scot a believer in the
doctrine of signatures.[33]Other men of the same period prominent in science who held
similar beliefs we can scarcely stop to mention. There was Vincent
de Beauvais, the great encyclopedist, and Bernard Gordon, a
physician of Montpellier and a medical writer of considerable note,
who nevertheless recommended the use of a magic formula for the
treatment of epilepsy.[34]There was
Albertus Magnus with his trust in such wonderful powers of stones
as to cure ulcers, counteract potions, conciliate human hearts, and
win battles; and his theory that ligatures and suspensions, and
gems carved with proper images possess similar strange
virtues.[35]There was Arnald of
Villanova who propounded such admirable doctrines as that a
physician ought first of all to understand the chief functions of
life and chief organs of the body and that the science of
particular things is the foundation of all knowledge, and yet who
believed in astrological medicine, wrote on oneiromancy and
interpreted dreams, translated treatises on incantations, ligatures
and other magic devices, and composed a book on theTetragrammatonor
ineffable name of Jehovah.[36]That marvelous power of words—especially of the divine names
of angels and of the Supreme Deity—which we may suppose Arnald to
have touched upon in hisTetragrammaton,was
discussed at length by a series of scholars at the close of the
fifteenth and beginning of the sixteenth century whose names are
most familiar to the student of those times. These men pushed the
practice of allegorical interpretation of sacred writings, which
had been in constant vogue among religious and theological writers
from the days of the early Christian Fathers, to the extreme of
discovering sublime secrets not only by regarding every incident
and object in Scripture as a parable, but by treating the text
itself as a cryptogram. Not only, like Isidore, did they see in
every numerical measurement in the Bible mystic meaning, but in the
very letters they doubted not there was hidden that knowledge by
which one might gain control of all the processes of the universe;
nay, penetrate through the ten sephiroth to the unspeakable and
infinite source of all. For our visible universe is but the
reflected image of an invisible, and each has subtle and
practically unlimited power over the other. The key to that power
is words. Such were the doctrines held by Pico Della Mirandola
(1463-1494) who asserted that no science gave surer proof of
Christ's divinity than magical and cabalistic science;[37]such were the doctrines of the renowned
humanist, John Reuchlin, who connected letters in the sacred text
with individual angels;[38]of Henry
Cornelius Agrippa (1486-1535) who, inspired by Reuchlin'sDe verbe mirificoandDe arte
cabalistica, declared that whoever knew
the true pronunciation of the name Jehovah had "the world in his
mouth;"[39]of Trithemius from whom
Paracelsus is said to have acquired the "Cabala of the spiritual,
astral and material worlds."[40]Moreover, the writings of men primarily devoted to science
continued through the sixteenth and on into the seventeenth century
to contain much the same occult theories that Michael Scot, Roger
Bacon and Albertus Magnus had accepted and discussed. Jerome
Cardan, one of the most prominent men of his time in mathematics
and medicine—indeed, the discoverer of new processes in the former
science—nevertheless believed in a strong attraction and sympathy
between the heavenly bodies and our own, cast horoscopes and wrote
on judicial astrology. In hisArithmetiche treated of
the marvelous properties of certain numbers; in other writings he
credulously discussed demons, ghosts, incantations, divination and
chiromancy. His thirteen books on metoposcopy explain how to tell a
person's character, ability and destiny by a minute examination of
the lines on different portions of the body and by warts. He owned
a selenite which he believed prevented sleep and a jacinth to which
he attributed an opposite influence.[41]The vagaries of Paracelsus are notorious, and yet he was far
more than a mere quack. Tycho Brahe (1546-1601) was a faithful
follower of experimental method. He saw that the science of the
stars could amount to little unless based on a mass of correct
observations, and was one of the first to devote his life to that
foundation of patient and systematic drudgery on which the great
structure of modern science is being reared. His painstaking
endeavor to have accurate instruments and his care to make
allowance for possible error were the marks, rare enough in those
days, of the true scientist. Yet he made many an astrological
prognostication, and was, as his biographer puts it, "a perfect son
of the sixteenth century, believing the universe to be woven
together by mysterious connecting threads which the contemplation
of the stars or of the elements of nature might unravel, and
thereby lift the veil of the future."[42]He also dabbled in alchemy, believed in relations of occult
sympathy between "the ethereal and elementary worlds," and filled
his mind with the teachings of Hermes Trismegistus, Geber, Arnald
of Villanova, Raymond Lullius, Roger Bacon, Albertus Magnus, and
Paracelsus.Finally, even Francis Bacon, famed as the draughtsman of the
chart which henceforth guided explorers in the domain of science,
thought that there was considerable value in physiognomy and the
interpretation of natural dreams, though the superstition and
phantasies of later ages had debased those subjects;[43]and in divination if not "conducted by
blind authority."[44]He said that by a
reformed astrology one might predict plagues, famines, wars,
seditions, sects, great human migrations and "all great
disturbances or innovations in both natural and civil
affairs."[45]Such are the beliefs which for a long time pervaded the
thought and learning of Europe; beliefs of the widespread
acceptance of which we have noted but a few striking illustrations.
They constitute a varied and formidable class of convictions. There
was the notion that from such things as the marks upon one's body,
or from one's dreams, or from peals of thunder, flight of birds,
entrails of sacrificial victims and the movements of the stars, we
can foretell the future. There was the assumption that certain
precious stones, certain plants and trees and fountains, certain
animals or parts of animals have strange and wonderful virtues.
There was the idea that man, too, possesses marvelous powers to the
extent that he can fascinate and bewitch his fellows. Nor should we
forget the attribution to the heavenly bodies of an enormous
influence over minerals and vegetation, over human health and
character, over national constitutions and customs, even over
religious movements. We find this notion of occult virtue extended
to things without physical reality: to words, to numbers, to
written characters and formulæ. It is applied to certain actions
and ways of doing things: to "ligatures and suspensions," for
instance. Then there was the belief that wonders may be wrought by
the aid of demons, and that incantations, suffumigations, and the
like are of great value in invoking spirits. Finally, there was a
vague general notion that not only are the ethereal and elementary
worlds joined by occult sympathy, but that all parts of the
universe are somehow mystically connected, and that perhaps a
single magic key may be discovered by which we may become masters
of the entire universe.
