Alchemy

The exploration and application of the sciences, particularly chemistry and astrology. Alchemists were mainly dedicated to the producing of gold from baser metals and other various materials.

Alchemy is an early protoscientific practice combining elements of chemistry, physics, astrology, art, semiotics, metallurgy, medicine, mysticism, and religion. There were three main goals many alchemists sought for. The most renowned goal of alchemy is the transmutation of any metal into either gold or silver.Also they tried to create universal panacea, a remedy that would cure all diseases and prolong life indefinitely.

Although these were not the only uses for the science, they were the ones most documented and well known. Starting with the Middle Ages, European alchemists invested much effort on the search for the "philosopher's stone", a legendary substance that was believed to be an essential ingredient for either or both of those goals.
