The pre-science of transformation, and the root system of chemistry.
Documented
A word that crossed three civilizations
Khem or kheme may come from the Egyptian name for Egypt, the black land, or from Greek chymeia, the art of pouring. Arabic wrapped it as al-kimiya, medieval Latin as alchimia. The chemistry that replaced it kept the same root and dropped the article.
Assessment: Documented etymology across three languages. The word is a fossil of the discipline's migration.
Stories
The gold was never the point
The beloved retelling: serious alchemists were never chasing metal, gold was a metaphor for the perfected soul, and only fools read the recipes literally. Jung built an entire psychology on this reading.
Assessment: Half true. Spiritual allegory is documented in the texts, but so are actual furnaces, actual recipes, and actual charlatans who sold gold-making to kings. Both alchemies existed, often in the same person.
Interesting claims
A suppressed technology of consciousness
The claim: alchemical literature encodes a working method for transforming human consciousness, suppressed first by the Church and then by materialist science, readable only by initiates.
Assessment: The encoding is real, since alchemical texts were deliberately veiled. The working method is unverifiable by design, which is why the claim has survived four centuries of chemistry. Filed as living mythology with a real documentary base.

Worth asking
If a discipline can be killed by its own success, did chemistry kill alchemy or become it?
