SYMBOLS OF THE ALCHEMISTS AND THEIR SIGNIFICATIONS
I love this definition:
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. As practiced historically, 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, andspiritual concepts, theories and practices.
P.S. I painted this chart the other night, can you tell I used gold paint? It look really cool when the sunlight hits it at an angle.
