Today we recognize alchemy as a pseudoscience, and give chemistry its rightful place as a serious scientific field, but the two terms initially overlapped in meaning before separating by the 17th century, just as astrology and astronomy did during the same period.

Alchemy and alchemist are in fact older words than chemistry and chemist in English. Alchemists believed that lead could be “perfected” into gold, that diseases could be cured, and that life could be prolonged through transmutation, or a change of some essential element into a superior form. Their secretive experiments, usually involving heat and the mixing of liquids, led to the development of pharmacology and the rise of modern chemistry.

The long route to English for alchemist began with the Greek word chēmeia, which probably came from the word chyma (“fluid”), derived from the verb chein, meaning “to pour.” It then passed to Arabic, which added its definite article al- (“the”) to the Greek root. The word then passed from Latin to French before coming to English. Some other words derived from Arabic also retain the al- in English, such as algebra, algorithm, and alcohol; in fact, the transformative liquid that was constantly being sought through experimentation by alchemists is another word with the Arabic al- prefix: elixir.

This power to transform things for the better, real or imagined, led to figurative meanings for alchemy and alchemist.

The History of Alchemy

The medieval chemical science and speculative philosophy that focused on the attempt to change less valuable metals into gold, to find a universal cure for disease, and to discover a means of prolonging life indefinitely is called alchemy. It was practiced in much of the ancient world, from China and India to Greece. Alchemy migrated to Egypt and was later revived in 12th-century Europe through translations of Arabic texts into Latin. Medieval European alchemists made some useful discoveries, including mineral acids and alcohol. The revival led to the development of pharmacology and to the rise of modern chemistry. The gold-making processes of alchemists were finally discredited, but not until the 19th century.
