Alchemy
Encyclopedia
Alchemy is an influential philosophical tradition whose early practitioners’ claims to profound powers were known from antiquity. The defining objectives of alchemy are varied; these include the creation of the fabled philosopher's stone
Philosopher's stone

 practical applications, and its esoteric aspects. The former is pursued by historians of the physical sciences who have examined the subject in terms of proto-chemistry, medicine, and charlatanism. The latter is of interest to the historians of esotericism, psychologists, spiritual and new age communities, and hermetic philosophers. The subject has also made an ongoing impact on literature and the arts. Despite the modern split, numerous sources stress an integration of esoteric and exoteric approaches to alchemy. Holmyard, when writing on exoteric aspects, states that they can not be properly appreciated if the esoteric is not always kept in mind. The prototype for this model can be found in Bolos of Mendes' second century BCE work, Physika kai Mystika (On Physical and Mystical Matters). Marie-Louise von Franz

 applauded alchemy for its consistency with Christian teachings. Both the transmutation of common metals into gold and the universal panacea symbolized evolution from an imperfect, diseased, corruptible, and ephemeral state towards a perfect, healthy, incorruptible, and everlasting state; and the philosopher's stone then represented a mystic key that would make this evolution possible. Applied to the alchemist himself, the twin goal symbolized his evolution from ignorance to enlightenment, and the stone represented a hidden spiritual truth or power that would lead to that goal.

In his 1766 Alchemical Catechism, Théodore Henri de Tschudi denotes that the usage of the metals was a symbol:
During the renaissance, alchemy broke into more distinct schools placing spiritual alchemists in high contrast with those working with literal metals and chemicals. While most spiritual alchemists also incorporate elements of exotericism, examples of a purely spiritual alchemy can be traced back as far as the sixteenth century, when Jacob Boehme used alchemical terminology in strictly mystical writings.

The recent work of Principe and Newman, seeks to reject the 'spiritual interpretation' of alchemy, stating it arose as a product of the Victorian occult revival. There is evidence to support that some classical alchemical sources were adulterated during this time to give greater weight to the spiritual aspects of alchemy.

The etymology is still open, and recent research indicates that the Egyptian derivation may be valid.

History

Alchemy covers several philosophical traditions spanning some four millennia and three continents. These traditions' general penchant for cryptic and symbolic language makes it hard to trace their mutual influences and "genetic" relationships. One can distinguish at least three major strands, which appear to be largely independent, at least in their earlier stages: Chinese alchemy

. According to Aristotle, each element had a sphere to which it belonged and to which it would return if left undisturbed. The four elements of the Greek were mostly qualitative aspects of matter, not quantitative, as our modern elements are. "...True alchemy never regarded earth, air, water, and fire as corporeal or chemical substances in the present-day sense of the word. The four elements are simply the primary, and most general, qualities by means of which the amorphous and purely quantitative substance of all bodies first reveals itself in differentiated form." Later alchemists extensively developed the mystical aspects of this concept.

Most of the Greco-Roman alchemists preceding Zosimos are known only by pseudonyms, such as Moses, Isis, Cleopatra, Democritus, and Ostanes. Others authors such as Komarios, and Chymes, we only know through fragments of text. After 400 CE, Greek alchemical writers occupied themselves solely in commenting on the works of these predecessors. By the middle of the seventh century alchemy was almost an entirely mystical discipline. It was at that time that Khalid Ibn Yazid sparked its migration from Alexandria to the Islamic world, facilitating the translation and preservation of Greek alchemical texts in the 8th and 9th centuries.

Thus, Jabir theorized, by rearranging the qualities of one metal, a different metal would result. By this reasoning, the search for the philosopher's stone

In his authentic works such as the Book of Minerals, he observed and commented on the operations and theories of alchemical authorities like Hermes and Democritus, and unnamed alchemists of his time. Albertus critically compared these to the writings of Aristotle and Avicenna, where they concerned the transmutation of metals. From the time shortly after his death through to the fifteenth century, twenty-eight or more alchemical tracts were misattributed to him, a common practice giving rise to his reputation as an accomplished alchemist. Likewise, alchemical texts have been attributed to Albert’s student Thomas Aquinas

 around 1247, he dramatically shifted his studies towards a vision of a universal science which included alchemy and astrology.

 highlighted this integration, calling attention to the importance of alchemy to the papacy. Like the Greeks before him, Bacon acknowledged the division of alchemy into the practical and theoretical. He notes that the theoretical lied outside the scope of Aristotle, the natural philosophers, and all Latin writers of his time. The practical however, confirmed the theoretical through experiment, and Bacon advocated its uses in natural science and medicine.

It was notable for its inclusion of practical chemical operations alongside sulphur-mercury theory, and the unusual clarity with which they were described. By the end of the 13th century, alchemy had developed into a fairly structured system of belief. Adepts believed in the macrocosm-microcosm theories of Hermes, that is to say, they believed that processes that affect minerals and other substances could have an effect on the human body (for example, if one could learn the secret of purifying gold, one could use the technique to purify the human soul

Alchemy in the Renaissance and modern age

European alchemy continued in this way through the dawning of the Renaissance

. The era also saw a flourishing of con artists who would use chemical tricks and sleight of hand to "demonstrate" the transmutation of common metals into gold, or claim to possess secret knowledge that—with a "small" initial investment—would surely lead to that goal.

However, it is important to emphasize that the terms "chemia" and "alchemia" were used as synonyms in the Renaissance, and the differences between alchemy, chemistry and small-scale assaying and metallurgy were not as neat as in the present day. There were important overlaps between practitioners, and trying to classify them into wizards (alchemists), scientists (chemists) and craftsmen (metallurgists) is anachronistic.

One of these men who emerged at the beginning of the 16th century was the German Heinrich Cornelius Agrippa
Heinrich Cornelius Agrippa
Heinrich Cornelius Agrippa von Nettesheim was a German magician, occult writer, theologian, astrologer, and alchemist.-Life:Agrippa was born in Cologne in 1486...

 (1486–1535). This alchemist believed himself to be a wizard capable of summoning spirits. His influence was negligible, but like Flamel, he produced writings which were referred to by alchemists of later years. Again like Flamel, he did much to change alchemy from a mystical philosophy to an occult

ist magic. He did keep alive the philosophies of the earlier alchemists, including experimental science, numerology, etc., but he added magic theory, which reinforced the idea of alchemy as an occultist belief. In spite of all this, Agrippa still considered himself a Christian, though his views often came into conflict with the church.

, and Pythagorean philosophies; however, Hermetical science had so much Aristotelian theory that his rejection of Gnosticism was practically meaningless. In particular, Paracelsus rejected the magic theories of Agrippa and Flamel.

Paracelsus pioneered the use of chemicals and minerals in medicine, and wrote "Many have said of Alchemy, that it is for the making of gold and silver. For me such is not the aim, but to consider only what virtue and power may lie in medicines." His hermetical views were that sickness and health in the body relied on the harmony of man the microcosm and Nature the macrocosm. He took an approach different from those before him, using this analogy not in the manner of soul-purification but in the manner that humans must have certain balances of minerals in their bodies, and that certain illnesses of the body had chemical remedies that could cure them. While his attempts of treating diseases with such remedies as Mercury might seem ill-advised from a modern point of view, his basic idea of chemically produced medicines has stood time surprisingly well. Alchemy became known as the spagyric art after Greek words meaning to separate and to join together the word probably being coined by Paracelsus. Compare this with one of the dictum

The decline of Western alchemy

The demise of Western alchemy was brought about by the rise of modern science with its emphasis on rigorous quantitative experimentation and its disdain for "ancient wisdom". Although the seeds of these events were planted as early as the 17th century, alchemy still flourished for some two hundred years, and in fact may have reached its apogee in the 18th century. As late as 1781 James Price claimed to have produced a powder that could transmute mercury into silver or gold.

He assumed nothing in his experiments and compiled every piece of relevant data; in a typical experiment, Boyle would note the place in which the experiment was carried out, the wind characteristics, the position of the Sun and Moon, and the barometer reading, all just in case they proved to be relevant.

The words "alchemy" and "chemistry" were used interchangeably during most of the seventeenth century; only during the eighteenth century was a distinction drawn rigidly between the two. In the eighteen century, "alchemy" was considered to be restricted to the realm of "gold making", leading to the popular belief that most, if not all, alchemists were charlatans, and the tradition itself nothing more than a fraud. The obscure and secretive writings of the alchemists was used as a case by those who wished to forward a fraudulent and non-scientific opinion of alchemy. In order to protect the developing science of modern chemistry from the negative censure of which alchemy was being subjected, academic writers during the scientific Enlightenment attempted, for the sake of survival, to separate and divorce the "new" chemistry from the "old" practices of alchemy. This move was mostly successful, and the consequences of this continued into the nineteenth and twentieth centuries, and even to the present day.

During the occult revival of the early nineteenth century, alchemy received new attention as an occult science. The esoteric or occultist school, which arose during the nineteenth century, held (and continues to hold) the view that the substances and operations mentioned in alchemical literature are to be interpreted in a spiritual sense, and it downplays the role of the alchemy as a practical tradition or protoscience. This interpretation further forwarded the view that alchemy is an art primarily concerned with spiritual enlightenment or illumination, as opposed to the physical manipulation of apparatus and chemicals, and claims that the obscure language of the alchemical texts were an allegorical guise for spiritual, moral or mystical processes. In the first half of the 19th century, one established chemist, Baron Carl Reichenbach

In the nineteenth century revival of alchemy, the two most seminal figures were Mary Anne Atwood, and Ethan Allen Hitchcock

Modern alchemy

Due to the complexity and obscurity of alchemical literature, and the eighteenth century disappearance of remaining alchemical practitioners into the area of chemistry; the general understanding of alchemy in the general public, modern practitioners, and also many historians of science, have been strongly influenced by several distinct and radically different interpretations. Hundreds of books including adulterated translations of classical alchemical literature were published throughout the early nineteenth century. Many of these continue to be reprinted today by esoteric book publishing houses, along with modern books on spiritual alchemy and poor translations of older alchemical texts. These are then used as sources by modern authors to support spiritual interpretations. Over half of the books on alchemy published since 1970 support spiritual interpretations, mostly using previously adulterated documents to support their conclusions. Many of these books continue to be taken seriously, even appearing in university bookshelves.

Esoteric interpretations of alchemy remains strong to this day, and continue to influence both the public and academic perceptions of the history of alchemy. Today, numerous esoteric alchemical groups continue to perpetuate modern interpretations of alchemy, sometimes merging in concepts from New Age

Jung did not completely reject the material experiments of the alchemists, but he massively downplayed it, writing that the transmutation was performed in the mind of the alchemist. He claimed the material substances and procedures were only a projection of the alchemists' internal state, while the real substance to be transformed was the mind itself.
