Hermeticism and Alchemy

The Western esoteric tradition has often been described as a single “long conversation” running from Hellenistic Egypt to the present day, but that figure flattens what is in fact a tangle of distinct, sometimes competing, sometimes antagonistic lineages. There is the Greek and Latin literary tradition of the Corpus Hermeticum and the Latin Asclepius; there is the practical and laboratory tradition of alchemy, with its Greek, Arabic, Latin, and Chinese branches; there is the Neoplatonic theurgic tradition of Iamblichus and Proclus; there is the Christian Kabbalah of the Renaissance, in which the Jewish mystical tradition was rerouted into a Hermetic-prisca-theologia framework by Pico della Mirandola and Johannes Reuchlin; and there is the post-Enlightenment revival, in which groups like the Hermetic Order of the Golden Dawn re-synthesised the whole into a ritual-magic system that is still operative in the West today. The two oldest and most pervasive currents in this tangle are Hermeticism proper and alchemy. They share a cosmology and a vocabulary; they are not the same thing, and the relationship between them changed more than once across two millennia.

A note on vocabulary: “Hermeticism” here refers narrowly to the body of texts and doctrines attributed to Hermes Trismegistus and to the lineages that took those texts as their foundation. “Alchemy” refers to the practical and theoretical tradition of transmutative work, whether material, spiritual, or both. The two are often braided; they were braided from the start. The Egyptian milieu that produced the Corpus Hermeticum in the second or third century CE is the same milieu that produced the earliest Greek alchemical papyri, and the late-antique practitioners who copied Hermetic treatises into the same codices with alchemical recipes (the Leiden and Stockholm papyri, dated to roughly the third century CE) did not draw the boundary we draw today. What follows is a tour through that braided tradition as it has actually been transmitted — with named scholars, dated texts, and the disputed points marked as such.

The Hermetic Texts

The literary foundation of the tradition is a corpus of treatises gathered under the name of Hermes Trismegistus — “thrice-greatest Hermes” — a syncretic figure in whom the Greek Hermes and the Egyptian Thoth were merged. The most important surviving collection is the Corpus Hermeticum, a group of seventeen Greek treatises discovered in 1460, almost certainly by the monk Leonardo da Pistoia, in Macedonia. The single manuscript that survives (now Codex Parisinus graecus 1220) was brought to Italy, where Marsilio Ficino translated it into Latin in 1463 at the request of his patron Cosimo de’ Medici. The first printed Latin edition appeared in 1471 as part of Ficino’s Opera (the editio princeps), and the first printed Greek edition was edited by Adrien Turnèbe in Paris in 1554 (Copenhaver 1992; Fowden 1993).

The opening treatise of the Corpus, the Poimandres, sets the tone for the whole collection. Written in the form of a vision granted to Hermes in a state of deep trance, it describes the generation of the cosmos by the divine mind (nous), the soul’s descent into the material realm, and the soul’s eventual return to the divine. The human being is described, in the Greek phrase Copenhaver translates as “a marvel to be wondered at,” as the only creature capable of contemplating the cosmos and so of recovering its origin. This is the doctrine that medieval and Renaissance readers took as the signature Hermetic claim about the human place in the world.

A second Latin treatise, the Asclepius, was known in the Latin West centuries before the rest of the corpus resurfaced. It carries a more political theology than the Poimandres, including a famous passage in which Egyptian cult statues are described as receptacles of divine spirit, animated by ritual technique. That passage caused considerable discomfort among Christian readers, and was one of the texts Isaac Casaubon cited in his De rebus sacris et ecclesiasticis exercitationes of 1614 — the study that effectively killed the Renaissance belief that the Hermetic texts were of pre-Mosaic Egyptian antiquity and forced the modern view that they are products of the early Christian centuries, composed in Greek, in dialogue with both Middle Platonism and the Jewish and Christian traditions of their time (Copenhaver 1992; Faivre 1995; Hanegraaff 2013).

A third text, the Emerald Tablet (Latin Tabula Smaragdina), is a short, dense, aphoristic work. Its famous central sentence — “that which is below is like that which is above, and that which is above is like that which is below” — became the single most quoted formula of the Western esoteric tradition. The Latin text is generally treated by modern scholars as a translation, made in the Latin Middle Ages, of an Arabic original usually dated to the seventh through tenth centuries CE; a small number of scholars continue to defend a Latin or Syriac priority, but the Arabic-first view is the modern consensus (Copenhaver 1992; Principe 2013).

In the early twentieth century a fourth Hermetic text became widely influential, especially in the English-speaking world: the Kybalion, published in 1908 by the Yogi Publication Society of Chicago under the pseudonym “Three Initiates.” The work is now generally attributed to William Walker Atkinson (1862–1932), an American New Thought writer who also wrote as “Yogi Ramacharaka.” The seven Hermetic principles set out in the Kybalion — mentalism, correspondence, vibration, polarity, rhythm, cause and effect, gender — are not found together in any older Hermetic text, and the work is best read, as modern scholarship reads it, as a 1908 compilation drawing on the Corpus, the Emerald Tablet, Knorr von Rosenroth’s Kabbala Denudata (1677–1684), and the New Thought movement of the period. The seven principles are treated in detail in a separate article. The point worth making here is that the Kybalion is a modern text, not a recovered ancient one; the sevenfold scheme is Atkinson’s, not the Corpus’s.

As Above, So Below

The principle of correspondence, “as above, so below,” is the structural key to the entire Hermetic worldview. The cosmos, in this framework, is a graded continuum running from the highest reaches of the divine mind, through the heavenly spheres, the four elements, the mineral, plant, and animal kingdoms, the human being, and the lower orders of being. Each level reflects the others. The laws that operate at one level operate analogously at every other level, and the practitioner who learns the signature of a thing on one level can read it on every other level (Fowden 1993; Hanegraaff 2013).

This is the framework in which astrology becomes meaningful, but in a different sense from the modern horoscopic one: the movement of the planets is not a mechanical cause in the modern sense, but a sign of changes in the human soul, and the correspondence between planet and soul is a real, structural one, not a symbolic convenience. The same framework makes alchemy meaningful. The transformation of base metal into gold is at the same time, and on the same continuum, a transformation of the practitioner. The famous obscurity of alchemical writing — the riddles, the red herrings, the deliberate veils — is at least partly a strategy for keeping both readings in play at once.

The corollary is the doctrine of the human being as microcosm — the “little world” that contains, in compressed form, the structure of the macrocosm, the greater world. To know oneself is to know the cosmos. To purify the soul is to participate in the purification of the world. The doctrine is older than the Hermetic texts: one finds it in the Timaeus of Plato, in the De Mundo attributed to Aristotle, and in the fragments of the Pythagoreans; what the Hermetic texts add is the technical vocabulary of ascent, descent, regeneration, and the divine nous by which the ascent is performed. The lineage is mapped in Fowden’s The Egyptian Hermes (1993) and in Bouthoorn and Hanegraaff (2005).

Hermes Trismegistus and the Doctrine of Ancient Theology

The figure at the heart of the tradition is not a historical person. Hermes Trismegistus is a composite, formed in the Hellenistic period by the merger of the Egyptian god Thoth, credited with the invention of writing and the keeping of the divine records, with the Greek Hermes, the messenger of the gods and the guide of souls. The earliest known references to “Thoth the thrice-greatest” appear in Hellenistic Egypt of the second century BCE; by the early Christian centuries, lists of supposed writings by Hermes ran into the tens of thousands. Augustine, in the De Civitate Dei, complains, with some weariness, that the books of Hermes were “innumerable.”

What Hermes represented to later tradition was the idea of an original, revealed wisdom given to humanity at the beginning of history and preserved in a chain of transmission. This is the doctrine of prisca theologia — the “ancient theology” — which held that a single divine truth had been revealed to all the great sages of antiquity and that their apparent disagreements were differences of language, not of substance. In the Renaissance this doctrine, given its modern form by Marsilio Ficino, made it possible to treat Moses, Plato, Orpheus, Zoroaster, and Hermes as all teaching the same underlying wisdom. The doctrine, in Hanegraaff’s analysis (2013), is less a philosophical claim than a rhetorical strategy: it allowed Renaissance humanists to import the older esoteric corpus into Christian theology. Casaubon’s 1614 demonstration that the Hermetic texts were not of pre-Mosaic antiquity was therefore not merely a philological finding; it was a destabilisation of the prisca theologia framework on which the Renaissance had rested (Faivre 1995; Hanegraaff 2013; Copenhaver 1992).

The Birth of Alchemy

Alchemy arose independently in several places, but the Western alchemical tradition is rooted in the Hellenistic Egypt of the first few centuries CE, the same milieu that produced the Hermetic texts. The earliest identifiable alchemical author is Zosimos of Panopolis, who wrote in Greek in the late third or early fourth century CE and who described the alchemical work in terms drawn directly from the religious imagery of death, dissolution, and resurrection. Zosimos wrote of the prima materia, the first matter from which all things are made, and developed the central alchemical image of the telos, the perfected state, in vocabulary taken from the religious mystery traditions. His treatise On the Letter Omega and the Final Account of his visionary ascent through the cosmic spheres are the first extant examples of alchemical writing that is also self-consciously esoteric. The question of exactly how much of the technical laboratory vocabulary in Zosimos is borrowed from older Greek metallurgical writing, and how much is original, is still debated, but the technical and the esoteric are unmistakably braided in his work (Principe 2013; Newman 2004; Bouthoorn and Hanegraaff 2005).

In China a parallel tradition developed. The earliest named figure is Wei Boyang, who in the second century CE composed the Cantong qi, a waidan (“external alchemy”) text on the preparation of elixirs of immortality. The later neidan (“internal alchemy”) tradition took the waidan vocabulary and rerouted it inward: the elixir is no longer a substance compounded in the furnace but a state cultivated in the body. The fourth-century Taoist Ge Hong is the most important figure of the waidan tradition; his Baopuzi (c. 320 CE) contains the first extended Chinese treatment of laboratory alchemy. The Chinese tradition, like the Western, operated on both a material and a spiritual level, and the two readings were not so much alternatives as two registers of the same practice. The differences are real: the Chinese tradition has no figure exactly corresponding to Hermes Trismegistus, no Corpus of revealed writings, and no doctrine of correspondence of the specific “as above, so below” form; but the family resemblance is close enough that Joseph Needham, in the relevant volume of his Science and Civilisation in China (1974), treats the two as comparative cases in the history of speculative chemistry (Needham 1974; Principe 2013).

In the Islamic world the Greek and Egyptian alchemical texts were taken up, translated into Arabic, and significantly extended from the eighth century onward. The most important figure is Jabir ibn Hayyan, an Arab polymath traditionally said to be from Khorasan (modern Iran; the question of his exact ethnicity is contested, and modern scholars treat him as ethnically Arab, born in Tus), whose vast corpus systematised alchemical theory by linking the metals to the planets, the elements, and the qualities of hot, cold, wet, and dry. Jabir’s sulphur–mercury theory of metallic composition — that all metals are composed of sulphur and mercury in varying proportions — became the standard theory of metallic composition in the Arabic and Latin traditions. His work is also the source of much of the practical laboratory technique associated with medieval European alchemy: distillation, sublimation, calcination, crystallisation, and the use of apparatus (the alembic, the athanor, the cucurbit) recognisably ancestral to the apparatus of modern chemistry. The Jabirian corpus runs to several thousand pages in the critical edition of Kraus and Holmyard, and the question of which treatises are by Jabir himself and which by later followers is one the modern scholarship has not fully resolved (Principe 2013; Newman 2004; Holmyard 1957).

The Medieval Latin Tradition

When the Greek and Arabic alchemical corpus was translated into Latin in the twelfth and thirteenth centuries, alchemy entered the European university world and acquired a new set of practitioners and patrons. The most important translation centre was Toledo, where the work of Gerard of Cremona (d. 1187) and his successors produced a stream of Latin translations of Arabic scientific, philosophical, and alchemical texts; the secondary centres were Sicily (where Frederick II’s court was a major patron) and, later, Venice and the other Italian cities. Albertus Magnus wrote alchemical treatises alongside his commentaries on Aristotle and his work in natural science. Roger Bacon used alchemical imagery in his philosophical and theological writings and proposed, in his Opus Maius and the De Admirabili Scientia, that alchemy could in principle contribute to the prolongation of life. These figures are often remembered as proto-scientists, but in their own context they were working firmly within a tradition that saw the transformation of matter and the transformation of the soul as a single project (Principe 2013; Newman 1991).

The Summa Perfectionis attributed to “Geber” (the Latin Geber, distinct from the Arabic Jabir) and probably composed in the late thirteenth century by Paul of Taranto (fl. c. 1250–1300) — gives the most influential Latin description of the philosopher’s stone: a single substance, prepared from a single raw material, possessing the two properties the tradition attributed to it. The Summa is also the most important Latin statement of the sulphur–mercury theory of metallic composition, and it remained the standard alchemical textbook for two centuries. Lawrence Principe’s The Aspiring Adept (1998) and William R. Newman’s The “Summa Perfectionis” of Pseudo-Geber (1991) are the standard modern studies of this text and its context.

The dominant alchemical figure of the sixteenth century is Paracelsus, the Swiss physician whose real name was Theophrastus von Hohenheim. Paracelsus did not so much reject the older Arabic and Latin traditions as add to them: he kept the four elements of the older tradition but added, as a deeper level, the tria prima of salt, sulphur, and mercury, and he insisted that the proper aim of alchemy was the making of medicines, not the making of gold. He called this new art iatrochemistry, medicine by chemical means, and he used alchemical ideas — the doctrine of signatures, the correspondence between planets and organs, the correspondence between poisons and cures — to design new treatments. Paracelsus is also the source of much of the magical and theurgical dimension of later European esotericism, and his influence runs directly into the Rosicrucian manifestos of the early seventeenth century and from there into the whole edifice of modern occultism. The standard modern study of the Paracelsian revolution is Principe’s The Secrets of Alchemy (2013).

The English alchemical tradition of the same period includes two figures of very different kinds. John Dee (1527–1608/9), the mathematician, navigator, and Hermetic philosopher who served as adviser to Elizabeth I, is not primarily remembered as a practicing alchemist; he was a mathematician, a cartographer, a Hermeticist, and a scryer, and his alchemical interests, though real, were secondary to his Hermetic and Enochian work. The “British Empire” attribution sometimes given to Dee in popular writing is not secure: the phrase appears in continental usage as early as Gerardus Mercator (1564), and Dee’s use of it in his The Brytish Monarchie of 1577 is not the first. Isaac Newton, in the late seventeenth and early eighteenth centuries, devoted a significant portion of his intellectual life to alchemical experimentation. Newton’s alchemical papers, only fully catalogued in the twentieth century (the bulk purchased by John Maynard Keynes and Abraham Yahuda in the 1930s; the major modern catalogue is by William R. Newman and the Chymistry of Isaac Newton project, begun in 2002), are one of the largest bodies of his unpublished work. The standard modern study is Newman’s Promethean Ambitions (2004).

Alchemy in the Arabic World

The Arabic alchemical tradition, often called al-kīmiyā’ in its original language, is the bridge through which the Greek and Egyptian alchemical material reached medieval Europe, and one of the great creative periods of the alchemical tradition in its own right. The tradition begins with the translation of Greek alchemical texts into Arabic under the Abbasid caliphs, particularly during the eighth and ninth centuries, when Baghdad was the centre of a vast translation movement under caliphs like al-Mansur, al-Mahdi, and al-Ma’mun. The work of the translators produced a new vocabulary of chemical and alchemical terms — al-iksīr, al-anbīq, al-qinnab — that is still the basis of the modern European chemical vocabulary. From this base, the Arabic alchemists developed alchemical theory in ways the Greek tradition had not anticipated. The sulphur–mercury theory of metallic composition, the planetary-metal correspondences, the laboratory techniques of distillation and sublimation, the systematic classification of mineral, vegetable, and animal substances, and the use of the balance and the alembic are all in significant measure the work of the Arabic tradition. Principe’s The Secrets of Alchemy (2013) gives a good accessible account in the context of the wider history.

The Stages of the Great Work

Whatever their disagreements, Western alchemists from Zosimos onward described the alchemical process as a sequence of stages, generally four, often assigned characteristic colours. The first stage is nigredo, the blackening: the putrefaction of the prima materia. In the symbolic reading, this is the encounter with the shadow, the descent into the unconscious. The second stage is albedo, the whitening: a purification in which the washed and rectified matter emerges in a state of innocence, often represented as a white powder or a white queen. The third stage, citrinitas, the yellowing, is recognised in some traditions as a transitional moment; in older Latin and Arabic traditions it is often folded into the albedo, and the four-stage scheme is reduced to three. The fourth stage is rubedo, the reddening: the final perfection in which the matter is fixed, the stone is produced, the work is complete. The central alchemical motto solve et coagula — dissolve and coagulate — is the running summary of the whole sequence.

The relationship between these four stages and the chemical operations of the alchemist has been debated for centuries. The chemical reading treats the stages as a literal laboratory procedure: dissolve the ore, separate the volatile from the fixed, recombine, repeat. The symbolic reading treats them as a description of inner transformation. Most historical alchemists held to both readings simultaneously, often deliberately. The modern psychological reading, most influentially developed by Carl Gustav Jung in Psychology and Alchemy (German 1944, English 1953) and Mysterium Coniunctionis (German 1955–56, English 1963), treats the alchemical images as symbolic descriptions of the process of individuation. Marie-Louise von Franz, Jung’s principal collaborator on the alchemical material, developed the symbolic reading in Aureum Speculum (1980). The Jungian reading has been criticised from several directions. William R. Newman, in The “Summa perfectionis” of Pseudo-Geber (1991) and Promethean Ambitions (2004), and Lawrence Principe, in The Aspiring Adept (1998) and The Secrets of Alchemy (2013), have argued that Jung and his followers selected alchemical texts that fit the psychological model and ignored those that did not. The criticisms are serious. The Jungian reading remains, however, a powerful and influential interpretation.

The Philosopher’s Stone

The product of the Great Work was the lapis philosophorum, the philosopher’s stone, an emblematic substance of extraordinary power. The alchemists attributed to it two main properties. The first was the transmutation of base metals into gold. The second was the prolongation of life, often described as an elixir or as a medicine. Neither claim, taken literally, has been substantiated, and no modern laboratory has reproduced either. The alchemists themselves often warned that the stone was not a substance in the ordinary sense and that those who sought it only in the laboratory would not find it; the most consistent alchemical voices — from the Aurora Consurgens to Michael Maier’s Atalanta Fugiens (1617/18) to the Rosarium Philosophorum of 1550 — are explicit on the point. But the warning should not be over-generalised. Albertus Magnus, Roger Bacon, the Latin Geber, George Ripley (fl. 1470s), and Johann Joachim Becher (1635–1682) took the laboratory work seriously as laboratory work, and the symbolic reading does not exhaust what they were doing.

In the symbolic reading the stone represents the perfected self, the conjunction of opposites, the unification of the human and the divine. The tradition often distinguishes between a white stone and a red stone, associated with the moon and the sun, with silver and gold, with the albedo and the rubedo; the white stone is the medicine of the soul, the red stone the medicine of the body.

The most famous name in alchemical legend is Nicolas Flamel (c. 1330–1418), a Parisian scrivener (a scribe and copyist of documents) who also worked in the book trade and owned several properties; the popular description of him as a “notary” is not quite right, but it is close enough. The legend that he had produced the stone began to circulate in the seventeenth century and became the prototype of the romance of the alchemist who succeeds where all others fail. The historical Flamel did in fact endow several Parisian churches and hospitals with the proceeds of his business, which is part of the basis of the legend; the Livre des figures hiéroglyphiques attributed to him is now generally treated by scholarship as a seventeenth- or eighteenth-century forgery (Principe 2013).

Hermeticism and Christian Kabbalah

In the Renaissance the Hermetic tradition entered into a deep and lasting marriage with another tradition it had never before encountered: the Jewish mystical tradition of the Kabbalah. The two were brought together in the work of Giovanni Pico della Mirandola, the Florentine philosopher, and in the translations and commentaries of his circle, especially the work of the Christian Hebraist Johannes Reuchlin (1455–1522), whose De Arte Cabbalistica of 1517 is the first systematic Christian treatment of the Kabbalah. Pico was the younger man; Reuchlin was the elder. The Kabbalah offered a rich and developed symbolic system — the ten sephirot, the four worlds, the Tree of Life — that could be mapped onto Hermetic theology, and the Hermetic texts offered a Greek and Egyptian pedigree that could lend dignity to the new study of Jewish mysticism. The result was a synthetic tradition often called Christian Kabbalah, later known as Hermetic Qabalah, that would dominate the esoteric world of Europe for the next three centuries. The standard modern study of the Christian Kabbalah is the relevant sections of Gershom Scholem’s Kabbalah (1974) and the more recent work of Joseph Dan; the standard treatment of the Hermetic synthesis is Faivre’s The Eternal Hermes (1995) and Hanegraaff’s Western Esotericism (2013).

This synthesis is the direct ancestor of the most important esoteric order of the modern period, the Hermetic Order of the Golden Dawn of the late nineteenth century, and through the Golden Dawn it is the direct ancestor of much of contemporary Western occultism, including most contemporary Wicca, most contemporary Thelema, and a great deal of contemporary ceremonial magic. The Tarot, the astrological correspondences, the ritual magic of the pentagram and the hexagram, the grade system of many modern orders — all of these are direct descendants of the Renaissance marriage of Hermes and the Kabbalah.

The Survival of Hermetic Ideas

By the eighteenth century the philosophical establishment had largely turned away from Hermeticism. The Royal Society of London, founded in 1660, was one of several institutions that explicitly rejected the alchemical tradition in favour of an empirical programme of natural philosophy. The Hermetic tradition survived in three main currents. The first was the continuing practice of alchemy by small groups of adepts, particularly in German-speaking lands and in the Czech lands, into the nineteenth century. The second was the Romantic revival of the late eighteenth and early nineteenth centuries, in which the alchemists and Hermeticists were rediscovered by poets and philosophers as ancestors of a more spiritual and imaginative relationship to nature. The third, and most important, was the new occult revival of the late nineteenth century, in which figures like Helena Blavatsky, the founders of the Golden Dawn, the Theosophical Society, and a host of smaller orders recovered the Hermetic and alchemical corpus and reinterpreted it in a modern spiritual framework.

This revived tradition has remained a continuous presence in Western esotericism from the late nineteenth century to the present. It is the tradition behind contemporary ceremonial magic, much of contemporary witchcraft and Wicca, most contemporary Tarot practice, the modern revival of astrology, and the continuing practice of alchemy as a contemplative and therapeutic art. The symbol of the ouroboros, the principle of correspondence, the doctrine of the microcosm, the four stages of the Great Work — all of these remain live, working parts of contemporary esoteric culture. The standard scholarly treatment of the post-Enlightenment survival of the tradition is Hanegraaff’s Western Esotericism: A Guide for the Perplexed (2013) and Antoine Faivre’s Theosophy, Imagination, Tradition (2000).

The Hermetic tradition, then, is not an antique curiosity. It is a working intellectual and practical current that has shaped the way many people in the West have thought about the relationship between the human being and the world for two thousand years. The question that has exercised historians, and that the modern academic study of Western esotericism has been working on for a generation, is whether and how to treat the tradition as a single object of study: as a religion, as a philosophy, as a cultural current, or as a network of practices. The most useful answer, perhaps, is the one that Wouter Hanegraaff has offered: as a network of practices and discourses that share a family resemblance and that have been in continuous conversation with one another, often across confessional and disciplinary boundaries (Hanegraaff 2013).
