Maistryefull merveylous and Archimastrye Is the tincture of holy Alkimy;

A wonderful Science, secrete Philosophie,

A singular grace and gifte of th’Almightie:

Which never was found by labour of Mann,

But it by Teaching, or by Revalacion begann.

(THOMAS NORTON, The Ordinall of Alchemy, c. 1477)

In 1477, having succeeded after years of study in preparing both the Great Red Elixir and the Elixir of Life, only to have them stolen from him, Thomas Norton of Bristol composed the lively early English poem, The Ordinall of Alchemy. Here he expounded in an orderly fashion the procedures to be adopted in the alchemical process, just as an Ordinal lists chronologically the order of the Church’s liturgy for the year. Unfortunately, although the reader learns much of would-be alchemists’ mistakes, and of the ingredients and apparatus, of the subtle and gross works, and of the financial backing, workers and astrological signs needed to conduct the ‘Great Work’ successfully, the secret of transmutation remains tantalisingly obscure.

The historian Herbert Butterfield once dismissed historians of alchemy as ‘tinctured with the kind of lunacy they set out to describe’; for this reason, he thought, it was impossible to discover the actual state of things alchemical. Nineteenth-century chemists were less embarrassed by the subject. Justus von Liebig, for example, used the following notes to open his Giessen lecture course:

Distinction between today’s method of investigating nature from that in olden times. History of chemistry, especially alchemy …

Liebig’s presumption, still widespread, was that alchemy was the precursor of chemistry and that modern chemistry arose from a rather dubious, if colourful, past¹:

The most lively imagination is not capable of devising a thought which could have acted more powerfully and constantly on the minds and faculties of men, than that very idea of the Philosopher’s Stone. Without this idea, chemistry would not now stand in its present perfection …[for] in order to know that the Philosopher’s Stone did not really exist, it was indispensable that every substance accessible … should be observed and examined.

To most nineteenth-century chemists, and historians and novelists, alchemy had been a human aberration, and the task of the historian seemed to be to sift the wheat from the chaff and to discuss only those alchemical views (chiefly practical) that had contributed positively to the development of scientific chemistry. As one historiographer of the subject has put it²:

[the historian] merely split open the fruit to get the seeds, which were for him the only things of value. In the fruit as a whole, its shape, colour, and smell, he had no interest.

But what was alchemy? The familiar response is that it involved the pursuit of the transmutation of base metals such as lead into gold. In practice, the aims of the alchemist were often a good deal broader, and it is only because we take a false perspective in seeing chemistry as arising from alchemy that we normally narrowly focus on to alchemy’s concern with the transformation of metals. However, as Carl Jung pointed out in his study Psychology and Alchemy, there are similarities between the emblems, symbols and drawings used in European alchemy and the dreams of ordinary twentieth-century people. One does not have to believe in psychoanalysis or Jungism to see that the most obvious explanation for this is that alchemical activities were often concerned with a spiritual quest by humankind to make sense of the universe. It follows that alchemy could have taken different forms in different cultures at different times.

At the beginning of the twentieth century, after the elderly French chemist, Marcellin Berthelot, had made available French translations of a number of Greek alchemical texts, an American chemist, Arthur J. Hopkins (1864–1939), showed how they could be interpreted as practical procedures involving dyeing and a series of colour changes. He was able to show how Greek alchemists, influenced by Greek philosophy and the practical knowledge of dyers, metallurgists and pharmacists, had followed out three distinctive transmutation procedures, which involved either tincturing metals or alloys with gold (as described in the Leiden and Stockholm papyri), or chemically manipulating a ‘prime matter’ mixture of lead, tin, copper and iron through a series of black, white, yellow and purple stages (which Hopkins was able to replicate in the laboratory), or, as in the surviving fragments of Mary the Jewess, using sublimating sulphur to colour lead and copper.

While Hopkins’ explanation of alchemical procedures has formed the basis of all subsequent historical work on early alchemical texts, and while Jung’s psychological interpretation has stimulated interest in alchemical language and symbolism, it was the work of the historian of religion, Mircea Eliade (1907–86), who, following studies of contemporary metallurgical practices of primitive peoples in the 1920s, firmly placed alchemy in the context of anthropology and myth in Forgerons et Alchimistes (1956).

These three twentieth-century interpretations of alchemy, dyeing, psychological individuation and anthropology, together with the historical investigation of Chinese alchemy being undertaken by Joseph Needham and Nathan Sivin in the 1960s, stimulated the late Harry Sheppard to devise a broad definition of the nature of alchemy³:

Alchemy is a cosmic art by which parts of that cosmos – the mineral and animal parts – can be liberated from their temporal existence and attain states of perfection, gold in the case of minerals, and for humans, longevity, immortality, and finally redemption. Such transformations can be brought about on the one hand, by the use of a material substance such as ‘the philosopher’s stone’ or elixir, or, on the other hand, by revelatory knowledge or psychological enlightenment.

The merit of such a general definition is not only that it makes it clear that there were two kinds of alchemical activity, the exoteric or material and the esoteric or spiritual, which could be pursued separately or together, but that time was a significant element in alchemy’s practices and rituals. Both material and spiritual perfection take time to achieve or acquire, albeit the alchemist might discover methods whereby these temporal processes could be speeded up. As Ben Jonson’s Subtle says in The Alchemist, ‘The same we say of Lead and other Metals, which would be Gold, if they had the time.’ And in a final sense, the definition implies that, for the alchemist, the attainment of the goals of material, and/or spiritual, perfection will mean a release from time itself: materially through riches and the attainment of independence from worldly economic cares, and spiritually by the achievement of immortality.

The definition also helps us to understand the relationship between the alchemies of different cultures. Although some historians have looked for a singular, unique origin for alchemy, which then diffused geographically into other cultures, most historians now accept that alchemy arose in various (perhaps all?) early cultures. For example, all cultures that developed a metallurgy, whether in Siberia, Indonesia or Africa, appear to have developed mythologies that explained the presence of metals within the earth in terms of their generation and growth. Like embryos, metals grew in the womb of mother Nature. The work of the early metallurgical artisan had an obstetrical character, being accompanied by rituals that may well have had their parallel in those that accompanied childbirth. Such a model of universal origin need not rule out later linkages and influences. The idea of the elixir of life, for example, which is found prominently in Indian and Chinese alchemy, but not in Greek alchemy, was probably diffused to fourteenth-century Europe through Arabic alchemy. The biochemist and Sinologist, Joseph Needham, has called the belief and practice of using botanical, zoological, mineralogical and chemical knowledge to prepare drugs or elixirs ‘macrobiotics’, and has found considerable evidence that the Chinese were able to extract steroid preparations from urine.

Alongside macrobiotics, Needham has identified two other operational concepts found in alchemical practice throughout the world, aurifiction and aurifaction. Aurifiction, or gold-faking, which is the imitation of gold or other precious materials – whether as deliberate deception or not depending upon the circumstances (compare modern synthetic products) – is associated with technicians and artisans. Aurifaction, or gold-making, is ‘the belief that it is possible to make gold (or “a gold”, or an artificial “gold”) indistinguishable from or as good as (if not better than) natural gold, from other different substances’. This, Needham suggests, tended to be the conviction of natural philosophers rather than artisans. The former, coming from a different social class than the aurifictors, either knew nothing of the assaying tests for gold, or jewellery, or rejected their validity.
