alchemy

Definition

The premodern and early modern study of physical changes, particularly in Europe, Arabia, and China; and chiefly in pursuit of an elixir of immortality, a universal panacea, and/or a philosopher's stone able to transmute base metals into gold, eventually developing into chemistry.

Etymology

From Old French alkimie, arquemie (French alchimie), from Medieval Latin alchēmia, from Arabic اَلْكِيمِيَاء (al-kīmiyāʔ), from Ancient Greek χυμείᾱ (khumeíā, “art of alloying metals”), from χύμα (khúma, “ingot, bar”). Compare Spanish alquimia and Italian alchimia.

Example Sentences

• "And yet surely to alchemy this right is due, that it may be compared to the husbandman whereof Æsop makes the fable; that, when he died, told his sons that he had left unto them gold buried underground in his vineyard; and they digged over all the ground, and gold they found none; but by reason of their stirring and digging the mould about the roots of their vines, they had a great vintage the year following: so assuredly the search and stir to make gold hath brought to light a great number of good and fruitful inventions and experiments, as well for the disclosing of nature as for the use of man’s life."
• "The [Isaac] Newton that emerges from the [unpublished] manuscripts is far from the popular image of a rational practitioner of cold and pure reason. The architect of modern science was himself not very modern. He was obsessed with alchemy."
• "The purpose of physical alchemy—as opposed to its various spiritual pursuits—was to treat the supposed leprosity of base metals such as lead, refining and purifying them into gold."
