Tria Prima (Three Primes): Meanings

Updated: Jul 30

The tria prima or Three Primes are the three main elements of ancient philosophers, medieval physicians and ubiquitous alchemists. They're portrayed as salt, sulfur, and mercury, and apply physically and symbolically to health, psychology and world view.

Salt represents that which is fixed and stable. Sulfur symbolizes the flammable or volatile and mercury is neither fixed nor flammable. Paracelsus (1493 - 1541 AD) introduces the tria prima based on Islamic alchemy, based on Greek thought.


Nature holds the key to healing. A holistic approach opens the way for future developments in medical science and influences alternative medicine today. Before the tria prima, the concept of the four elements and interaction of mercury (female) and sulfur (male) prevails.

Paracelsianism, a pioneering medical movement inspired by his groundbreaking theories and therapies, emerges after his death. Alternative to conventional medicine, methods are rooted in Galen (129 - 216 AD) who promotes theory and typology of human temperaments.


The concept of tria prima is fundamental to the practice of Renaissance alchemy, helping unlock the mysteries of this ancient discipline. At this time alchemy is focused more on medicine, spirituality, wisdom and eternal life than on chrysopoeia.

Chrysopoeia or turning base metals to gold is illegal in medieval England with the 1404 edict by Henry IV called the Act Against Multiplying. It's also unlawful to take existing gold or silver and cause it to magically increase. The act is finally repealed in 1689.


The Three Primes or tria prima


  • Mercury (Quicksilver) is fusible and elusive, representing substances able to evaporate without undergoing combustion.

  • Sulfur (Sulphur) is associated with soul and combustibility, embodying the flammable nature of certain substances.

  • Salt represents solidity and stability, symbolizing what remains fixed under the intense heat of alchemical processes.

Alchemy sees these elements not only as physical substances but also as spiritual and philosophical principles. Salt, sulfur, and mercury correspond to the body, soul, and spirit respectively, forming a trinity to unite the material and the immaterial realms.


The tria prima exist in all matter, influencing properties and behavior of elements and the human consciousness. Understanding and manipulating these elements lets Renaissance alchemists unlock secrets of nature, attain enlightenment and understand cosmic mysteries.
