Alchemy is a tradition of natural philosophy and practice that sought to transform matter, above all to turn base metals into gold, to prepare medicines and elixirs of long life, and, for many practitioners, to perfect the soul. It flourished in Greco-Roman Egypt, the Islamic world, China, India and Europe, and it contributed techniques and ideas to early modern chemistry.

Origins
Western alchemy emerged in Greco-Roman Egypt, where metalworking and dyeing recipes met Greek philosophy and religious ideas. The earliest author whose works partly survive is Zosimos of Panopolis, active around 300 CE, who cited earlier authorities such as Mary the Jewess and the writings attributed to Democritus. Alchemical texts were often attributed to Hermes Trismegistus, which is why the art is also called the Hermetic art. The word itself passed from Greek khemeia into Arabic as al-kimiya and then into Latin; its deeper origin is uncertain, with proposals including an Egyptian word for the black soil of Egypt and a Greek word for pouring or casting metal.
Independent traditions developed elsewhere. Chinese alchemy, linked with Daoism, pursued elixirs of immortality through external preparations (waidan) and later through inner cultivation of the body's energies (neidan). Indian alchemy (rasashastra) centered on mercury and medicine.
Islamic and Medieval European Alchemy
Scholars in the Islamic world translated, systematized and expanded Greek alchemy. Writings attributed to Jabir ibn Hayyan, many probably composed by a circle of authors in the 9th and 10th centuries, proposed that metals are formed from sulfur and mercury in varying proportions and gave detailed laboratory procedures. The physician Abu Bakr al-Razi described substances and apparatus in practical terms.
Latin Europe learned alchemy from Arabic sources in the 12th century; Robert of Chester completed a translation in 1144. Words such as alkali, alembic, elixir and athanor came into European languages through this route. Medieval authors such as those writing under the name "Geber" produced influential technical texts, while others emphasized allegory and secrecy.
Theory and Symbols
Alchemists generally accepted the four elements of Aristotle and believed that all matter shared a common substrate, the prima materia, which could be purified and recombined. The great work (magnum opus) was often described in stages marked by color: blackening (nigredo), whitening (albedo), sometimes yellowing, and reddening (rubedo). Its goal was the philosopher's stone, a substance said to transmute metals and heal the body.
Alchemical writing is deliberately symbolic. The seven metals corresponded to the seven planets, and images such as the ouroboros, the green lion, the royal marriage of king and queen, and the hermaphrodite expressed processes of dissolution and union. Legends of the homunculus, an artificial human, also belong to this literature. The Hermetic principle of correspondence, summed up as as above, so below, linked laboratory work to the cosmos.
Alchemy and the Rise of Chemistry
In the 16th century Paracelsus redirected much alchemical effort toward medicine, promoting mineral remedies and the three principles of salt, sulfur and mercury. Court alchemists served rulers across Europe, while figures such as John Dee mixed alchemy with other occult pursuits. Robert Boyle and Isaac Newton both studied alchemy seriously; Newton left a very large body of alchemical manuscripts. Historians of science now see a gradual transition rather than a sharp break between alchemy and chemistry, with many laboratory techniques, such as distillation and sublimation, carried over. The belief that metals could be transmuted by chemical means was abandoned as modern chemistry and atomic theory developed; nuclear physics can change one element into another, but by entirely different processes and not economically into gold.
Key Texts
- The Emerald Tablet: a short Hermetic text, first known in Arabic, treated as a foundational statement of alchemical principles.
- The Jabirian corpus: a large body of Arabic writings on alchemy and natural philosophy attributed to Jabir ibn Hayyan.
- The Summa perfectionis: an influential Latin treatise of the late 13th century written under the name Geber.
- The Rosarium philosophorum: a 16th-century illustrated compilation whose images Jung later analyzed.
Spiritual Alchemy and Modern Influence
From the 19th century many occultists, including writers influenced by Eliphas Levi, interpreted alchemy mainly as a spiritual discipline in which the practitioner, not the metal, is transformed. The psychologist Carl Jung, in Psychology and Alchemy (1944) and later works, read alchemical images as projections of unconscious processes and as symbols of what he called individuation. Historians caution that most historical alchemists were also doing real laboratory work, so purely spiritual readings do not describe the whole tradition. Alchemy remains a rich source of imagery for art, literature, tarot and modern esoteric practice.

Frequently asked questions
What was the goal of alchemy?
Alchemists pursued several goals: transmuting base metals such as lead into gold or silver, preparing the philosopher's stone, making medicines and an elixir of long life, and, for many, purifying the soul. Different traditions weighted these aims differently, and the practical and spiritual sides were often intertwined.
Did alchemists ever turn lead into gold?
No verified alchemical transmutation of lead into gold has ever been documented. Reported successes were due to error, contamination or fraud. Modern nuclear physics can convert tiny amounts of one element into another in particle accelerators or reactors, but this is unrelated to alchemical methods and is far too costly to be practical.
Was Isaac Newton an alchemist?
Yes, in the sense that Newton studied alchemy intensively for decades, copying texts and performing experiments. He wrote more on alchemy than on optics. Historians see his alchemical work as part of his wider search for the hidden principles of nature, alongside his physics and theology.
