Alchemy refers to both an early form of the investigation of nature and an early philosophical and spiritual discipline. They both combine elements of chemistry, metallurgy, physics, medicine, astrology, semiotics, mysticism, spiritualism, and art. It has been practiced in Mesopotamia, Ancient Egypt, Persia, India, and China, in Classical Greece and Rome, in Muslim civilization, and then in Europe up to the 19th century in a complex network of schools and philosophical systems spanning at least 2500 years. Today the discipline is still active but is of interest mainly to historians of science and philosophy, and for its mystic, esoteric, and artistic aspects. Alchemy was one of the main precursors of modern sciences, and many substances and processes of ancient alchemy continue to be used by modern chemical and metallurgical industries.
Although alchemy has many aspects, it is perhaps best known in popular culture as the process used to change lead (or other elements) into gold. Another well known aspect is the search for the Philosopher's Stone, the possession of which would supposedly give a person the ability to transmute gold or to have eternal life..
Alchemical symbols, were used to denote most elements and some compounds until the 18th century. While the notation method was mostly standardized, styles and symbols varied between alchemists, this page shows the most commonly used ones, with some more recent additions used by alchemists today for substances unknown prior to the 19th century.
Planetary Glyphs Planetary metals were "dominated" or "ruled" by one of the seven planets known by the ancients. Although they occasionally have a symbol of their own (see table below), they were usually symbolized by the planet's symbol. Uranus, Neptune, and Pluto were not yet discovered while Alchemy was commonly practiced, though many modern alchemists consider them representative of Uranium, Neptunium and Plutonium, respectively.
