Alchemy

Alchemy is an ancient tradition, the primary objective of which was the creation of the mythical "philosopher's stone," which was said to be capable of turning base metals into gold or silver, and also act as an elixir of life that would confer youth and immortality upon its user. Alchemy can be viewed as a protoscience, a precursor to modern chemistry, having provided procedures, equipment, and terminology that are still in use. However, alchemy also included various non-scientific mythological, religious, and spiritual concepts, theories and practices.
