Scholars who had engaged themselves into alchemy, during the Middle Ages, had other names than that of alchemists: the children of the art, the initiated, the cosmopolitan, the adepts, the Rosicrucians, the whisperers, or the hermetic philosophers…
Aristotle adopted Democritus’ theory on the conception of matter. This conception resurfaced with John Dalton.
The four affirmations constituting the basis of alchemy:
. That matter is continuous and uniform
. That matter is composed of four elements: earth, air, water, and fire.
. The four fundamental characteristics are: cold, dry, hot, humid.
. The void does not exist.
Alchemy started, in fact, at Alexandria around the IXth century before J.C. In Arab, “Al-Kimiya”, means “philosopher stone”. The goal is the fabrication of a philosopher’s stone that transmutes metals into gold, and that permits the preparation of the panacea or universal remedy.
The alchemist language esoteric on purpose, so it can stay that of the initiated. In alchemy, the bodies are classified into solids, liquids, and vapors; according to their colors. The interact according to sympathetic and antipathetic notions.
