Sulphur is the first element of the tria prima, or three primes, which also consist of the elements salt (body) and mercury (mind).
In alchemy, sulphur represents the soul of all material and living things. The element is synonymous with consciousness and the expansion of thought. To the ancient alchemist, sulphur’s properties are dryness, heat, masculinity, evaporation, expansion, and dissolution.
Sometimes in Greek philosophy there is a link between sulphur and the “Logos,” meaning divine thought or the origin of speech.
To the alchemist, sulphur is the bridge that connects the body with mind. It is the understanding of the element’s presence in all living things and materials that is fundamental in all alchemical processes. Sulphur is the key to unlocking the inner workings of the soul and consciousness.
