Mercury (Alchemy)
In the ancient art of alchemy, such as in Hermeticism, mercury, sulfur, and salt were the Earth's three principle substances that represent the trinity in creation. As sulphur is the symbol for the active principle, mercury is the symbol of the passive principle.The symbol of Mercury is the cosmic womb being incubated by the cross of the four elements of creation - earth, air, fire and water. Rising up out of the Cosmic womb of the Creatrix Field, is a partial form whose features are not yet determined as the raw substances undergo purification under each Law of Alchemy to reach the final Magnum Opus.The light-energy of the Solar Force is the source all life and thus in alchemy considered the Universal Mercury. Also, on the earth in the physical plane, Mercury is described as a water element. When the raw material of the Earth unites with the Cosmic Womb of Mother, the divine fire water or Azoth is manifested. In the natural laws, all forms of energy are transferable from one source to another.
Each civilization had its own legends about Mercury (Alchemy), and it was used as everything from a medicine to a talisman. Mercury's chemical symbol, Hg, comes from the Greek "hydrargyrum" meaning liquid silver. Mercury is also known as "quicksilver," a reference to its mobility and used as the physical symbol to represent the Azoth or fire-water in ancient alchemy. Speed and mobility were characteristics of the Greek-Roman god, Mercury (Hermes), who served as a messenger of knowledge to all the other gods and shares his name with the planet nearest the sun.
Hermeticism
Parts of the Hermetica appeared in the 4th-century Gnostic library found in Nag Hammadi.— another famous tract is the Emerald Tablet of Thoth, which teaches the doctrine "as above, so below". The Hermetica are Egyptian-Greek wisdom texts from the 2nd and 3rd centuries CE, which are mostly presented as dialogues in which a teacher, generally identified as Hermes Trismegistus ("thrice-greatest Hermes"), enlightens a disciple. The texts form the basis of Hermeticism. They discuss the divine, the cosmos, mind, and nature. Some touch upon alchemy, astrology, and related concepts.
