The Hermetic literature divides into two branches. On the one hand

there are the philosophical treatises, such as those in the Corpus Hermeticum,

and the Asclepius, to which can be added some other specimens of

this literature, particularly the fragments preserved in the anthology of

excerpts compiled by Stobaeus. 1 On the other hand there is the astrological,

alchemical, and magical literature, much of which also went

under the name of Hermes Trismegistus. These two branches cannot be

kept entirely separate from one another. 2 Not only do we have in the

Asclepius an actual description of magical practices in the admiring reference

to the methods by which the Egyptians “made gods”, but also

even the loftiest and most mystical of the philosophical Hermetic treatises

presuppose, as we have seen, an astrological pattern in the cosmos.

Gnosticism and magic go together. The pessimist gnostic needs to

know the magical passwords and signs by which he may rid himself of

the evil material power of the stars in his upward ascent through the

spheres. The optimist gnostic has no fear to draw down by sympathetic

magic, invocations, talismans, those same powers of the universe

which he believes to be good.


The methods of sympathetic magic3 presuppose that continual effluvia

of influences pouring down onto the earth from the stars of which

the author of the Asclepius speaks. It was believed that these effluvia and

influences could be canalised and used by an operator with the requisite

knowledge. Every object in the material world was full of occult

sympathies poured down upon it from the star on which it depended.

The operator who wished to capture, let us say, the power of the planet

Venus, must know what plants belonged to Venus, what stones and

metals, what animals, and use only these when addressing Venus. He

must know the images of Venus and know how to inscribe these on

talismans made of the right Venus materials and at the right astrological

moment. Such images were held to capture the spirit or power of the

star and to hold or store it for use. Not only the planets had attached to

each of them a complicated pseudo-science of occult sympathies and

image-making, but the twelve signs of the zodiac each had their plants,

animals, images, and so on, and indeed so had all the constellations and

stars of the heavens. For the All was One, united by an infinitely complex

system of relationships. The magician was one who knew how to

enter into this system, and use it, by knowing the links of the chains of

influences descending vertically from above, and establishing for himself

a chain of ascending links by correct use of the occult sympathies

in terrestrial things, of celestial images, of invocations and names, and

the like. The methods and the cosmological background presupposed

are the same whether the magician is using these forces to try to obtain

concrete material benefits for himself, or whether he is using them

religiously, as in the hieratic magic described in the Asclepius, for insight

into the divine forces in nature and to assist his worship of them.

Into the Hellenistic astrology which is the background of the philosophical

Hermetica an Egyptian element had been absorbed, namely the

thirty-six decans, or thirty-six gods who ruled over the divisions into

ten of the 360 degrees of the circle of the zodiac. 4 That strange people,

the Egyptians, had divinised time, not merely in the abstract sense but

in the concrete sense that each moment of the day and night had its

god who must be placated as the moments passed. The decans, as they

came to be called in Hellenistic times, were really Egyptian sidereal

gods of time who had become absorbed in the Chaldean astrology and

affiliated to the zodiac. They all had images, which vary in different lists

of them, and these lists of the powerful images of the decans had come

out of the archives of the Egyptian temples. The decans had various

aspects. They had definite astrological significance, as “Horoscopes”

presiding over the forms of life born within the time periods over

which they presided, and they were assimilated to the planets domiciled

in their domain, and to the signs of the zodiac, three decans going

with each sign as its three “faces”. But they were also gods, and powerful

Egyptian gods, and this side of them was never forgotten, giving

them a mysterious importance. The high place which the author of the

Asclepius assigns to the “Thirty-Six Horoscopes” in his list of gods is a

genuinely Egyptian feature of that work, and in one of the Stobaeus

fragments we hear, within the familiar framework of a conversation

between Hermes and his son Tat, of the great importance of the



We have said, my child, that there is a body which envelops the whole

ensemble of the world: you should represent it to yourself as a circular

figure, for thus is the All.


I represent to myself such a figure, as you say, O father.


Represent now to yourself that, below the circle of this body, are

ranged the thirty-six decans, in the middle between the universal circle

and the circle of the zodiac, separating these two circles, and, as it

were sustaining the circle of the All and circumscribing the zodiac,

moving along the zodiac with the planets, and having the same force

as the movement of the All, alternatively with the Seven. . . . Pay attention

to this: since the decans command over the planets and we are

under the domination of the seven, do you not see how there comes to

us a certain influence of the decans, whether through the children of

the decans, or through the intermediary of the planets? 5


The decans appear here as powerful divine or demonic forces, close to

the circle of the All, and above the circles of the zodiac and the planets

and operating on things below either directly through their children or

sons, the demons, or through the intermediary of the planets.

Thus the philosophical Hermetica belong into the same framework of

thought as the practical Hermetica, the treatises on astrology or alchemy,

the lists of plants, animals, stones and the like grouped according to

their occult sympathies with the stars, the lists of images of planets,

signs, decans, with instructions as to how to make magical talismans

from them. The following are only a few examples from this vast and

complex literature ascribed to Hermes Trismegistus. There is a treatise

supposedly by Hermes on the names and powers of the twelve signs of

the zodiac6; others on which plants go with the signs and the planets7;

a book of Hermes Trismegistus to Asclepius on the occult virtues of

animals8; a treatise on astrological medicine dedicated by Hermes to

Ammon the Egyptian which describes how to treat illnesses caused by

bad stellar influences by building up links with the methods of sympathetic

magic and talismans to draw down, either an increase of good

virtue from the star which has been causing the trouble or bringing in

influences from another star. 9


The name of Hermes Trismegistus seems to have been particularly

strongly connected with the lists of images of the decans. The Liber

Hermetis Trismegisti, 10 a treatise on astrology and astrological magic which

has been brought to light in recent years begins with the decans, and

the Liber Sacer, 11 or sacred book, of Hermes, is a list of decan images, and

of the stones and plants in sympathy with each decan, with instructions

as to how to engrave the images on the correct stone, which is to

be fixed into a ring together with the relative plant; the wearer of the

ring must abstain from all foods antipathetic to the decan.

In short, Hermes Trismegistus is indeed a name to conjure with in

all this type of literature concerned with occult sympathies and talismans.

Again in his capacity as Hermes-Thoth, inventor of language, of

words which bind and unbind, he plays a rôle in magic, 12 and some of

the magical prayers and invocations assigned to him are like those in

the Corpus Hermeticum.


The name of Hermes Trismegistus was well known in the Middle

Ages and was connected with alchemy, and magic, particularly with

magic images or talismans. 13 The Middle Ages feared whatever they

knew of the decans as dangerous demons, and some of the books

supposedly by Hermes were strongly censured by Albertus Magnus as

containing diabolical magic. 14 The Augustinian censure of the demonworship

in the Asclepius (by which he may have meant in particular,

decan-worship) weighed heavily upon that work. However, mediaeval

writers interested in natural philosophy speak of him with respect;

for Roger Bacon he was the “Father of Philosophers”, 15 and he is

sometimes given a genealogy which makes him even more ancient

than Ficino or the designer of the Siena mosaic thought. In the preface

to a twelfth-century translation of an alchemical work, it is stated that

there were three Hermeses, namely Enoch, Noah, and the king, philosopher,

and prophet who reigned in Egypt after the Flood and was

called Hermes Triplex. The same genealogy of “Hermes Mercurius

Triplex” is also given in a thirteenth-century treatise on astrology, and

the same explanation of why he is “three-fold”. 16 It will be remembered

that Ficino in his argumentum before the Pimander gives a similar

explanation of “Trismegistus” as referring to Hermes in his triple capacity

of priest, philosopher, and king or law-giver. The mediaeval

genealogy, however, takes Hermes Triplex back before Moses to the

time of Noah.


There is an extremely comprehensive treatise on sympathetic and astral

magic, with particular reference to talismans, which goes under the

name of Picatrix. Though the authorship of Picatrix is not assigned to

Hermes Trismegistus, the work frequently mentions him with great

respect and it is important because it may have been one of Ficino’s

authorities on talismans and sympathetic magic.


Like many of the magical works attributed to Hermes which reached

the Western Middle Ages and the Renaissance, the Picatrix was originally

written in Arabic, 17 probably in the twelfth century. There was a big

influence of Hermetic and gnostic literature and ideas on the Arabic

world and particularly among the Arabs of Harran. Talismanic magic

was practised by these Arabs, and the influence came through the

Sabeans who were immersed in Hermetism, in both its philosophical

and religious, and its magical aspects. Picatrix is by an Arabic writer

under strong Sabean, that is to say, Hermetic, influence, and he gives

his lists of magic images, his practical advice on magical procedures, in

an elaborate philosophical setting, the philosophy expounded being in

many respects similar to that which we find in some treatises of the

Corpus Hermeticum and in the Asclepius. Ficino and his friends would be

able to recognise in the Picatrix many of the ideas and philosophicoreligious

sentiments expressed by the wonderful author of Pimander, the

Egyptian Moses and the prophet of Christianity, and yet here this philosophy

is in a context of practical magic, how to make talismans, how

to draw down the influences of the stars by establishing the chains of

links and correspondencies with the upper world.


The Latin translation of Picatrix18 is shorter than the Arabic text; in the

proem it is stated that the work has been translated from Arabic into

Spanish by order of Alfonso the Wise, but this Spanish translation has

not survived. The Latin Picatrix was certainly circulating a good deal in

the Italian Renaissance. 19 There was a copy of Picatrix in Pico della

Mirandola’s library. 20 It was known to Ludovico Lazzarelli, 21 a most

ardent Hermetist contemporary with Pico. Giovanni Francesco Pico,

nephew of the great Pico, shows some knowledge of it in a work

written after his uncle’s death. 22 Symphorien Champier, who edited a

new edition of the Hermetica but was anxious to dissociate Christian

Hermetism from the magic of the Asclepius, speaks of Picatrix (in 1514)

with disapproval and accuses Peter of Abano of having borrowed from

it. 23 The popularity of this text-book of magic is attested by the fact that

Rabelais directed one of his shafts at it when he spoke of “le reuerend

pere en Diable Picatris, recteur de la faculté diabologique”. 24 The

secretive way in which such a book circulated is described by

Agrippa D’Aubigné in a letter written between 1572 and 1575 in

which he says that King Henri III of France had imported some

magical books from Spain which he was allowed to see, after much

difficulty and not without solemnly swearing not to copy them;

amongst them were “les commantaires de Dom Jouan Picatrix de

Tollede”. 25


Thus there is a good deal of evidence that this Picatrix, though it was

never printed, had a considerable circulation in manuscript during the

fifteenth and sixteenth centuries. Since there is no manuscript of it

earlier than the fifteenth century, 26 it is possible that it began to circulate

in the same century as that which saw the apotheosis of Hermes



The Picatrix opens with pious prayers and promises to reveal profound

secrets. For knowledge is the best gift of God to man, to know

what is the root and principle of all things. The primal truth is not a

body, but it is One, One Truth, One Unity. All things come from it and

through it receive truth and unity in the perpetual movement of generation

and corruption. There is a hierarchy in things, and lower things

are raised to higher things; and higher things descend to lower things.

Man is a little world reflecting the great world of the cosmos, but

through his intellect the wise man can raise himself above the seven



From this short sample of the philosophy of Picatrix, it can be seen

that the magician bases himself upon a gnosis, an insight into the

nature of the All.


The order of nature is further expounded in two passages. 27 God or

the prima materia is without form. There derives from the formless

incorporeal One the series of


Intellectus or mens


Materia, or material nature, the elements and the elementata.


Spiritus descends from the above to the below and resides in the place

where it is caught (ubi captus est). Or, as it is put in another chapter28 “the

virtues of the superior bodies are the form and power of the inferiors,

and the form of the inferiors is of a material related to the virtues of the

superiors; and they are as it were joined together, because their corporeal

material (of terrestrial things) and their spiritual material (of the

stars) are one material.” The whole art of magic thus consists in

capturing and guiding the influx of spiritus into materia.

The most important of the means of doing this is through the making

of talismans, images of the stars inscribed on the correct materials,

at the right times, in the right frame of mind, and so on. The whole of

the first two long and complicated books of Picatrix is devoted to this

most difficult art which demands a deep knowledge of astronomy,

mathematics, music, metaphysics, and indeed practically everything,

for the introduction of spiritus into talismans is a most tricky business

and no one can succeed in it unless he is a resolute philosopher.

Lists of the images suitable for use on talismans are given, of which

the following are a few examples from the lists of planet images. 29


Two images of Saturn.

“The form of a man with a crow’s face and foot, sitting on a throne,

having in his right hand a spear and in his left a lance or an arrow.”

“The form of a man standing on a dragon, clothed in black and

holding in his right hand a sickle and in his left a spear.”


Two images of Jupiter.

“The form of a man sitting on an eagle, clothed in a garment, with

eagles beneath his feet. . . .”

“The form of a man with a lion’s face and bird’s feet, below them a

dragon with seven heads, holding an arrow in his right hand. . . .”


An image of Mars.

“The form of a man, crowned, holding a raised sword in his right hand.”


An image of Sol.

“The form of a king sitting on a throne, with a crown on his head and

beneath his feet the figure (magic character) of the sun.”


An image of Venus.

“The form of a woman with her hair unbound riding on a stag, having

in her right hand an apple, and in her left, flowers, and dressed in

white garments.”


An image of Mercury.

“The form of a man having a cock on his head, on a throne, having

feet like those of an eagle, with fire in the palm of his left hand and

having below his feet this sign (a magic character).”


An image of Luna.

“The form of a woman with a beautiful face on a dragon, with horns

on her head, with two snakes wound around her. . . . A snake is wound

around each of her arms, and above her head is a dragon, and another

dragon beneath her feet, each of these dragons having seven heads.”

As can be seen from these examples, the magic images of the planets

are usually recognisably related to the classical forms of these gods and

goddesses but with strange and barbaric additions and modifications.

There is a full list in Picatrix of the images of the thirty-six decans, 30

grouped with the signs of the zodiac to which they belong.


The images of the decans of Aries.

First decan. “A huge dark man with red eyes, holding a sword, and

clad in a white garment.”

Second decan. “A woman clad in green and lacking one leg.”

Third decan. “A man holding a golden sphere and dressed in red.”


And so the list goes on, for all the thirty-six decans belonging to the

twelve signs, all with weird and barbaric images.


Having fully dealt with talismans and their manufacture in his first

two books, the author of Picatrix discusses in his third book31 what

stones, plants, animals, and so on go with the different planets, signs,

and so on, giving full lists, what parts of the body go with the signs,

what are the colours of the planets, how to invoke the spirits of the

planets by calling on their names and powers, and so on. The fourth

book32 deals with similar matters, and with fumigations and ends with

orations to the planets.


The work is thus a most complete text-book for the magician, giving

the philosophy of nature on which talismanic and sympathetic magic is

based together with full instructions for its practice. Its objects are

strictly practical; the various talismans and procedures are used to gain

specific ends, for the cure of diseases, for long life, for success in

various enterprises, for escaping from prison, for overcoming one’s

enemies, for attracting the love of another person, and so on.

Hermes Trismegistus is often mentioned, as the source for some

talismanic images and in other connections, but there is in particular

one very striking passage in the fourth book of Picatrix in which

Hermes is stated to have been the first to use magic images and is

credited with having founded a marvellous city in Egypt.


There are among the Chaldeans very perfect masters in this art and

they affirm that Hermes was the first who constructed images by

means of which he knew how to regulate the Nile against the motion

of the moon. This man also built a temple to the Sun, and he knew

how to hide himself from all so that no one could see him, although he

was within it. It was he, too, who in the east of Egypt constructed a City

twelve miles (miliaria) long within which he constructed a castle which

had four gates in each of its four parts. On the eastern gate he placed

the form of an Eagle; on the wester gate, the form of a Bull; on the

southern gate the form of a Lion, and on the northern gate he constructed

the form of a Dog. Into these images he introduced spirits

which spoke with voices, nor could anyone enter the gates of the City

except by their permission. There he planted trees in the midst of

which was a great tree which bore the fruit of all generation. On the

summit of the castle he caused to be raised a tower thirty cubits high

on the top of which he ordered to be placed a light-house (rotunda) the

colour of which changed every day until the seventh day after which it

returned to the first colour, and so the City was illuminated with these

colours. Near the City there was abundance of waters in which dwelt

many kinds of fish. Around the circumference of the City he placed

engraved images and ordered them in such a manner that by their

virtue the inhabitants were made virtuous and withdrawn from all

wickedness and harm. The name of the City was Adocentyn. 33

Passed through the vivid imagination of the Arab of Harran, we seem

to have here something which reminds us of the hieratic religious

magic described in the Asclepius. Here are the man-made gods, statues of

the animal- and bird-shaped gods of Egypt, which Hermes Trismegistus

has animated by introducing spirits into them so that they speak with

voices and guard the gates of this magical Utopia. The colours of the

planets flash from the central tower, and these images around the circumference

of the City, are they perhaps images of the signs of the

zodiac and the decans which Hermes has known how to arrange so

that only good celestial influences are allowed into the City? The lawgiver

of the Egyptians is giving laws which must perforce be obeyed,

for he constrains the inhabitants of the City to be virtuous, and keeps

them healthy and wise, by his powerful manipulation of astral magic.

The tree of generation in the City may perhaps also mean that he

controls the generative powers, so that only the good, the wise, the

virtuous and the healthy are born.


In his striking passage about the City of Adocentyn, the author of

Picatrix soars above the level of his utilitarian prescriptions of individual

talismans as cures for tooth-ache, aids to business progress, means

for downing rivals, and the like, to a wider view of the possibilities

of magic. One might say that this City shows us Hermes Mercurius

Triplex in his triple rôle of Egyptian priest and god-maker, of

philosopher-magician, and of king and law-giver. Unfortunately no

date is given for the founding of Adocentyn, so we have no means of

knowing whether this took place in the time of Noah and soon after the

Flood, or in the time of Moses, or not much later than Moses. But the

pious admirer of those two “divine” books by the most ancient

Hermes—the Pimander and the Asclepius—might surely have been much

struck, by this vivid description of a City in which, as in Plato’s ideal

Republic, the wise philosopher is the ruler, and rules most forcibly by

means of the priestly Egyptian magic such as is described in the Asclepius.

The City of Adocentyn in which virtue is enforced on the inhabitants by

magic helps also to explain why, when the magical Egyptian religion

decayed, manners and morals went to rack and ruin, as is so movingly

described in the Lament. And in the prophecy in the Asclepius, after the

Lament, of the eventual restoration of the Egyptian religion, it is said:

The gods who exercise their dominion over the earth will be restored

one day and installed in a City at the extreme limit of Egypt, a City

which will be founded towards the setting sun, and into which will

hasten, by land and by sea, the whole race of mortal men. 34

In the context of the Asclepius, the City of Adocentyn might thus be seen,

both as the ideal Egyptian society before its fall, and as the ideal pattern

of its future and universal renovation.


The author of Picatrix also states, at the beginning of the passage

quoted above, that Hermes Trismegistus built a Temple to the Sun,

within which he presided invisibly, though this Sun Temple is not

explicitly connected with his City. Hermes as a builder of a Temple to

the Sun could also connect in the mind of the pious reader of Pimander

(by which I mean, of course, the fourteen treatises of the Corpus Hermeticum

which Ficino included under that title) and of the Asclepius, with the

many passages on the sun in those works. For example, in the Corpus

Hermeticum V it is stated that the sun is supreme among the gods of

heaven35; in the Corpus Hermeticum X, the author, using Platonic terminology,

compares the sun to the Good and its rays to the influx of the

intelligible splendour. 36 And in the list of the gods of Egypt in the

Asclepius the Sun ranks as far greater than one of the planets. 37 He is

above the thirty-six horoscopes in the list of gods, and the thirty-six are

above the spheres of the planets. To find Hermes Trismegistus in the

Picatrix as the builder of a Temple of the Sun, would thus accord perfectly

with the teaching of that holy priscus theologus in the Pimander and in

the Asclepius.


When Marsilio Ficino began to dabble in his magic, which included a

tentative use of talismans, there were plenty of mediaeval authorities

which he might have used who give lists of talismanic images, amongst

them Peter of Abano, who lists the decan images, and whom Ficino

cites by name38 in his treatise De vita coelitus comparanda, a possible translation

of which might be “On capturing the life of the stars”. He would

also find much encouragement for the practice of magic in certain of

the Neoplatonic authors whom he studied and translated, particularly

Proclus, or Iamblichus “On the Egyptian Mysteries”. Nevertheless, as D.

P. Walker has shown, his chief incentive or exemplar was almost certainly

the description of magic in the Asclepius. 39 Walker has suggested

Picatrix as among the possible sources for Ficino’s practical magic, 40 and

as the above analysis of that work has shown, the pious admirer of the

“divine” Pimander and the “divine” Asclepius would find much in this

practical treatise on talismanic magic to remind him of the utterances

of the most ancient Hermes Trismegistus in his two divine books. It

could have been the Picatrix, read in the context of his Hermetic studies,

which enabled the pious Christian Neoplatonic philosopher to make

the transition to a practice of magic.


Magic had never died out during the Middle Ages, in spite of the

efforts of the ecclesiastical authorities to exercise some check over it

and to banish its more extreme forms. Nor was it by any means only in

Florence and under cover of Ficino’s Neoplatonism, that the interest in

the magic images of the stars was reviving in Italy. On the other side of

the Appenines, in Ferrara, the Duke Borso d’Este had covered a great

room in his palace with a cycle of paintings representing the months of

the year and showing, in its central band, the signs of the zodiac with

the images of the thirty-six decans most strikingly painted. In this

room, the decoration of which was finished before 1470,41 we may

see, in the lowest band of the frescoes the omniform life of the court of

Ferrara and above it the images of the thirty-six strung out along the

zodiac. The series begins with the three decans of Aries and their sign

(Pl. 1a); though their forms are slightly variant from the images which

we quoted from the list in Picatrix they are easily recognisable as in the

main the same, the tall dark man in white (Pl. 1b), the woman who is

hiding under her skirts the unfortunate fact that she has only one leg,

the man holding a sphere or circle. Despite their charmingly modernised

costumes, these are really the Egyptian gods of time, the demons

banned by Augustine.


We are not, however, here concerned with revivals of star images in

other centres and outside the main current of Florentine Neoplatonism.

We are concerned with how it was that Marsilio Ficino, who took

such extreme care to present the revival of Plato and Neoplatonism as a

movement which could be accorded with Christianity, allowed a

fringe of magic to penetrate into this movement, thus inaugurating

those philosophies of the Renaissance in which magical undercurrents

are never far absent. The theory of the prisca theologia, of the piety and

antiquity of Hermes Trismegistus, priscus theologus and Magus, offered an

excuse for Ficino’s modern philosophical magic. The attraction of the

Asclepius had probably already been exerting its pull in the earlier

Renaissance, 42 and when Ficino—dropping Plato in order to translate

the Corpus Hermeticum first—found here a new revelation of the sanctity

of Hermes and a confirmation of Lactantius’ high opinion of him as

the prophet of the “Son of God”, he felt authorised to adopt the Lactantian

view and tried to evade the Augustinian warning. The presence of

Hermes Trismegistus inside the Duomo of Siena in the character of a

Gentile prophet which Lactantius had given him, is symptomatic of the

success of this rehabilitation.


We must not forget that the other prisci theologi, such as Orpheus or

Zoroaster, were also Magi, and also authorised by their antiquity

revivals of forms of magic. Yet Hermes Trismegistus is the most

important of the prisci magi from the point of view of the incorporation

of magic with philosophy, for in his case there was a body of supposedly

most ancient philosophical writings to be studied, and these

writings, in addition to their echoes of Moses and their prophetic

understandings of Christianity before Christ, also prophetically

shadowed the teachings of the divine Plato.


Lactantius wrote his Divine Institutes in the context of the rather superficially

Christianised Empire of Constantine, and his apologetics in that

work are directed towards persuading pagans to become Christians by

emphasising how much in paganism is close to Christianity, or prophetic

of Christianity. Between Lactantius and Augustine there had taken

place the pagan reaction under the apostate Emperor Julian, with its

attempt to drive out the new upstart religion by a return to the philosophical

“religion of the world” and to the mystery cults. In his “Hymn

to Helios”, Julian worships the Sun as the supreme god, the image of

the intelligible Good; and he says that there are also in the heavens a

multitude of other gods.


For as he (the Sun) divides the three spheres by four through the

zodiac . . . so he divides the zodiac also into twelve divine powers; and

again he divides every one of these twelve by three, so as to make

thirty-six gods in all. 43


Throughout Origen’s reply to Celsus it is evident how large a part

Egyptianism had played in the type of Neoplatonic religion which

came back in the pagan reaction. Celsus argues about how much “one

may learn from the Egyptians”, and Origen quotes the following

passage from his lost work:


They (the Egyptians) say that the body of man has been put under the

charge of thirty-six daemons, or ethereal gods of some sort. . . . Each

daemon is in charge of a different part. And they know the names of

the daemons in the local dialect, such as Chnoumen, Chnachoumen,

Knat, Sikat, Biou, Erou, Erebiou, Rhamanoor, and Rheianoor, and all

the other names which they use in their language. And by invoking

these they heal the sufferings of the various parts. What is there to

prevent anyone from paying honour both to these and to others if he

wishes, so that we can be in good health rather than ill, and have good

rather than bad luck, and be delivered from tortures and



To this Origen replies:


By these remarks Celsus is trying to drag our souls down to the daemons,

as though they had obtained charge over our bodies. He has

such a low opinion of paying an undivided and indivisible honour to

the God of the universe that he does not believe that the only God who

is worshipped and splendidly honoured is sufficient to grant the man

who honours Him, in consequence of the actual worship he offers to

Him, a power which prevents the attacks of daemons against the righteous

person. For he has never seen how, when the formula “in the

name of Jesus” is pronounced by true believers, it has healed not a few

people from diseases and demonic possession and other distresses.

. . . According to Celsus we might practise magic and sorcery

rather than Christianity, and believe in an unlimited number of daemons

rather than in the self-evident, and manifest supreme God. . . . 44

Writing after the pagan reaction, Augustine cannot accept Lactantius’

hopeful view of Hermes Trismegistus as the holy prophet of Christianity,

and utters his warning against the demon-worship of the Asclepius.

Yet even Augustine lent his support to the colossal misdating of that

work, by which Hermes appears as prophesying the coming of Christianity,

though he had this knowledge through the demons.


Believing in the immense antiquity of the Corpus Hermeticum and the

Asclepius, and following Lactantius’ estimate of their holy and divine

character, the pious Christian, Ficino, returns in his study of them, not,

as he thinks, to the antiquity of a priscus theologus who prophetically saw

into Christian truth (and authorised the practice of magic), but to the

type of pagan philosophical gnosis with Egyptianising and magical

tendencies, which characterised the anti-Christian reaction under

Julian the Apostate.


The type of magic with which we are to be concerned differs profoundly

from astrology which is not necessarily magic at all but a

mathematical science based on the belief that human destiny is irrevocably

governed by the stars, and that therefore from the study of a

person’s horoscope, the position of the stars at the time of his birth,

one can foretell his irrevocably foreordained future. This magic is astrological

only in the sense that it too bases itself upon the stars, their

images and influences, but it is a way of escaping from astrological

determinism by gaining power over the stars, guiding their influences

in the direction which the operator desires. Or, in the religious sense, it

is a way of salvation, of escape from material fortune and destiny, or of

obtaining insight into the divine. Hence “astrological magic” is not a

correct description of it, and hereafter, for want of a better term, I shall

call it “astral magic”.


It is in a very timid hesitating and cautious manner that Ficino

embarks on a mild form of astral magic, attempting to alter, to escape

from, his Saturnian horoscope by capturing, guiding towards himself,

more fortunate astral influences. Yet this comparatively harmless

attempt at astral medical therapy was to open a flood-gate through

which an astonishing revival of magic poured all over Europe.


1 Text of the Stobaeus fragments, with French translation, in C. H., vols. III and IV.

2 Scott tried to make such a separation, treating the philosophical Hermetica as quite

distinct from, and infinitely superior to, the “masses of rubbish” going under the name

of Hermes (Scott, I, p. 1). Festugière, on the other hand, devotes the first volume of his

Révélation to “L’Astrologie et les Sciences Occultes” in which he treats of the magical and

astrological texts as the necessary preliminary to the study of the philosophical Hermetica.

Cf. also Thorndike, I, pp. 287 ff.

Sciences in Antiquity (Princeton, 1952), Harper Torchbook Reprint, 1962, pp. 81 ff. The

specialised study of the decan images is that by W. Gundel, Dekane und Dekansternbilder,

Studien der Bibliothek Warburg, XIX, 1936.

5 C. H., III, pp. 34, 36 (Stobaeus Excerpt, VI). In the notes to this passage (ibid., p. L),

Festugière explains the children or sons of the decans as demons. Cf. also Révélation, I, pp.

118– 20; Scott, III, p. 374 (where a diagram is given to illustrate the fact that, according to

this passage, the decans are outside and above the circle of the zodiac).

8 Festugière, ibid., pp. 207 ff., discussing the “Livre court médical d’Hermès Trismégiste

selon la science astrologique et l’influx naturel des animaux, publié à l’adresse de son

disciple Asklépios.” As can be seen from this French translation of the title, this type of

treatise often brings in the same characters as those whom we meet in the philosophical

Hermetica. This treatise on animals is addressed by Hermes to Asclepius, like the

him in 1936.

Thorndike, II, p. 220. Albertus Magnus is one of the mediaeval writers who perhaps

knew the Latin Asclepius (see C. H., II, pp. 268– 9).

16 Ibid., pp. 215, 222. These are perhaps echoes of the twelfth-century pseudo-Hermetic

Liber Hermetis Mercurii Triplicis de VI rerum principiis, which has been published by Th. Silverstein

in Archives d’histoire doctrinale et littéraire du Moyen Age, 1955 (22), pp. 217– 302. On the

influence of this work, see above, p. 13, note 3.

17 The Arabic text of Picatrix, ed. H. Ritter, is published in Studien der Bibliothek Warburg, Vol.

XII, 1933, A German translation by H. Ritter and M. Plessner of the Arabic text is

published in Studies of the Warburg Institute, University of London, Vol. 27, 1962; an outline

in English of the contents of the Arabic text is given in this volume.

Besides these editions, see on the Picatrix, H. Ritter, Picatrix, ein arabisches Handbuch

hellenistischer Magie, in Vorträge der Bibliothek Warburg, 1922; Thorndike, II, pp. 813 ff.;

Festugière, I, pp. 389, 397 (in the appendix on Arabic Hermetic literature by Louis

Massignon); Garin, Cultura, pp. 159 ff.

18 Of this Latin translation there is as yet no edition. But it is the Latin translation which

was used in the Renaissance, not the Arabic original, and, since it differs somewhat from

the Arabic original, it must be used by students of Renaissance writers.

The manuscript of the Latin Picatrix which I have used is Sloane, 1305. Though a

seventeenth-century manuscript, it corresponds closely to earlier manuscripts (see

Thorndike, II, p. 822) and it has the advantage of being written in a clear and legible
