Latin Alchemy
In the 12th century the Christian West began to shed its habit of indifference or hostility to the secular literature of ancient and alien civilizations. Christian scholars were particularly attracted to Muslim Spain and Sicily and there made translations from both Arabic and Greek works, many of which were in some degree familiar, but some of which, including the literature of alchemy, were new.
The Greek alchemy of the Venice-Paris manuscript had much less impact than the work of ar-Razi and other Arabs, which emerged among the voluminous translations made in Spain about 1150 by Gerard of Cremona. By 1250 alchemy was familiar enough to enable such encyclopaedists as Vincent of Beauvais to discuss it fairly intelligibly, and before 1300 the subject was under discussion by the English philosopher and scientist Roger Bacon and the German philosopher, scientist, and theologian Albertus Magnus.
To learn about alchemy was to learn about chemistry, for Europe had no independent word to describe the science of matter. It had been touched upon in works concerned with other forms of change--e.g., the motion of projectiles, the aging of man, and similar Aristotelian concepts. On the practical side there were also artists' recipe books; but for the first time in the works of Bacon and Albertus Magnus change was discussed in a truly chemical sense, with Bacon treating the newly translated alchemy as a general science of matter for which he had great hopes.
But the more familiar alchemy became, the more clearly it was understood that gold making was the almost exclusive objective of alchemy, and Europeans proved no more resistant to the lure of this objective than their Arabic predecessors. By 1350, alchemical tracts were pouring out of the scriptoria (monastic copying rooms), and the Europeans had even taken over the tradition of anonymity and false attribution.
One authority wrote at length about supposed disagreements between two Arabs, Iahiae Abindinon and Geber Abinhaen, who were probably two versions of the name of Jabir ibn Hayyan. The most famous Jabirian work in Europe, The Sum of Perfection, is now thought to have been an original European composition. At about this time personal reminiscences of alchemists began to appear. Most famous was the Paris notary Nicolas Flamel (1330-1418), who claimed that he dreamed of an occult book, subsequently found it, and succeeded in deciphering it with the aid of a Jewish scholar learned in the mystic Hebrew writings known as the Kabbala. In 1382 Flamel claimed to have succeeded in the "Great Work" (gold making); certainly he became rich and made donations to churches.
By 1300 alchemists had begun the discovery of the mineral acids, a discovery that occupied about three centuries between the first evidence of the new strong water (aqua fortis--i.e., nitric acid) and the clear differentiation of the acids into three kinds: nitric, hydrochloric, and sulfuric. These three centuries saw prodigious efforts in European alchemy, for these spontaneously reactive and highly corrosive substances opened a whole new world of research. And yet, it was of little profit to chemistry, for the experiments were inhibited by the old objectives of separating the base metals into their "elements," concocting elixirs, and other traditional procedures.
The "water of life" (aqua vitae; i.e., alcohol) was probably discovered a little earlier than nitric acid, and some physicians and a few alchemists turned to the elixir of life as an objective. John of Rupescissa, a Catalonian monk who wrote c. 1350, prescribed virtually the same elixirs for metal ennoblement and for the preservation of health. His successors multiplied elixirs, which lost their uniqueness and finally simply became new medicines, often for specific ailments. Medical chemistry may have been conceived under Islam, but it was born in Europe. It only awaited christening by its great publicist, Paracelsus (1493-1541), who was the sworn enemy of the malpractices of 16th-century medicine and a vigorous advocate of "folk" and "chemical" remedies. By the end of the 16th century, medicine was divided into warring camps of Paracelsians and anti-Paracelsians, and the alchemists began to move en masse into pharmacy.
Paracelsian pharmacy was to lead, by a devious path, to modern chemistry, but gold making still persisted, though methods sometimes differed. SalomonTrismosin, purported author of the Splendor solis, or "Splendour of the Sun" (published 1598), engaged in extensive visits to alchemical adepts (a common practice) and claimed success through "kabbalistic and magical books in the Egyptian language." The impression given is that many had the secret of gold making but that most of them had acquired it from someone else and not from personal experimentation. Illustrations, often heavily symbolic, became particularly important, those of Splendor solis being far more complex than the text but clearly exercising a greater appeal, even to modern students.
Modern Alchemy
The possibility of chemical gold making was not conclusively disproved by scientific evidence until the 19th century. As rational a scientist as Sir Isaac Newton (1643-1727) had thought it worthwhile to experiment with it. The official attitude toward alchemy in the 16th to 18th century was ambivalent. On the one hand, The Art posed a threat to the control of precious metal and was often outlawed; on the other hand, there were obvious advantages to any sovereign who could control gold making. In "the metropolis of alchemy," Prague, the Holy Roman emperors Maximilian II (reigned 1564-76) and Rudolf II (reigned 1576-1612) proved ever-hopeful sponsors and entertained most of the leading alchemists of Europe.
This was not altogether to the alchemist's advantage. In 1595 Edward Kelley, an English alchemist and companion of the famous astrologer, alchemist, and mathematician John Dee, lost his life in an attempt to escape after imprisonment by Rudolf II, and in 1603 the elector of Saxony, Christian II, imprisoned and tortured the Scotsman Alexander Seton, who had been traveling about Europe performing well-publicized transmutations.
The situation was complicated by the fact that some alchemists were turning from gold making not to medicine but to a quasi-religious alchemy reminiscent of the Greek Synesius. Rudolf II made the German alchemist Michael Maier a count and his private secretary, although Maier's mystical and allegorical writings were, in the words of a modern authority, "distinguished for the extraordinary obscurity of his style" and made no claim to gold making. Neither did the German alchemist Heinrich Khunrath (c. 1560-1601), whose works have long been esteemed for their illustrations, make such a claim.
Conventional attempts at gold making were not dead, but by the 18th century alchemy had turned conclusively to religious aims. The rise of modern chemistry engendered not only general skepticism as to the possibility of making gold but also widespread dissatisfaction with the objectives of modern science, which were viewed as too limited. Unlike the scientists of the Middle Ages and Renaissance, the successors of Newton and the great 18th-century French chemist Antoine-Laurent Lavoisier limited their objectives in a way that amounted to a renunciation of what many had considered the most important question of science, the relation of man to the cosmos. Those who persisted in asking these questions came to feel an affinity with the alchemists and sought their answers in the texts of "esoteric," or spiritual, alchemy (as distinct from the "exoteric" alchemy of the gold makers), with its roots in Synesius and other late Greek alchemists of the Venice-Paris manuscript.
This spiritual alchemy, or Hermetism, as its practitioners often prefer to call it, was popularly associated with the supposititious Rosicrucian brotherhood, whose so-called Manifestoes (author unknown; popularly ascribed to the German theologian Johann Valentin Andreä) had appeared in Germany in the early 17th century and had attracted the favourable attention not only of such reforming alchemists as Michael Maier but also of many prominent philosophers who were disquieted by the mechanistic character of the new science. In modern times alchemy has become a focal point for various kinds of mysticism. The old alchemical literature continues to be scrutinized for evidence, because alchemical doctrine is claimed to have on more than one occasion come into the possession of man but always again been lost. Nor is its association with chemistry considered accidental.
In the words of the famous 19th-century English spiritual alchemist Mary Anne Atwood,
"Alchemy is an universal art of vital chemistry which by fermenting the human spirit purifies and finally dissolves it. . . . Alchemy is philosophy; it is the philosophy, the finding of the Sophia in the mind."
Assessments of alchemy
Accomplishments
The most persistent goals of alchemy have been the prolongation of life and the transmutation of base metals into gold. It appears that neither was accomplished, unless one credits alchemy with the consequences of modern chemotherapy and the cyclotron.
It has been said that alchemy can be credited with the development of the science of chemistry, a keystone of modern science. During the alchemical period the repertoire of known substances was enlarged (e.g., by the addition of sal ammoniac and saltpetre), alcohol and the mineral acids were discovered, and the basis was laid from which modern chemistry was to rise. Historians of chemistry have been tempted to credit alchemy with laying this base while at the same time regarding alchemy as mostly "wrong." It is far from clear, however, that the basis of chemistry was in fact laid by alchemy rather than medicine. During the crucial period of Arabic and early Latin alchemy, it appears that innovation owed more to nascent medical chemistry than to alchemy.
But those who explore the history of the science of matter, where matter is considered on a wider basis than the modern chemist understands the term, may find alchemy more rewarding. Numerous Hermetic writers of previous centuries claimed that the aims of their art could yet be achieved--indeed, that the true knowledge had been repeatedly found and repeatedly lost. This is a matter of judgment, but it can certainly be said that the modern chemist has not attained the goal sought by the alchemist. For those who are wedded to scientific chemistry, alchemy can have no further interest. For those who seek the wider goal, which was also that of the natural philosopher before the advent of "mechanical," "Newtonian," or "modern" science, the search is still on.
Interpretations
Charlatanism was a prominent feature of European alchemy during the 16th century, and such monarchs as Rudolf II--even if they had mainly themselves to blame--were not entirely without reason in incarcerating some of their resident adepts. The picturesqueness of this era, which also saw the birth of the modern science of chemistry, has led many historians of chemistry to view alchemy in general as a fraud.
Other historians of chemistry have attempted to differentiate the good from the bad in alchemy, citing as good the discovery of new substances and processes and the invention of new apparatus. Some of this was certainly accomplished by alchemists (e.g., Maria), but most of it is more justifiably ascribed to early pharmacists.
Scholars generally agree that alchemy had something to do with chemistry, but the modern Hermetic holds that chemistry was the handmaiden of alchemy, not the reverse. From this point of view the development of modern chemistry involved the abandonment of the true goal of the art.
Finally, a new interpretation was offered in the 1920s by the Swiss psychoanalyst Carl Jung, who, following the earlier work of the Austrian psychologist Herbert Silberer, judged alchemical literature to be explicable in psychological terms. Noticing the similarities between alchemical literature, particularly in its reliance on bizarre symbolic illustrations, and the dreams and fantasies of his patients, Jung viewed them as manifestations of a "collective unconscious" (inherited disposition). Jung's theory, still largely undeveloped, remains a challenge rather than an explanation.
