The Complete Alchemy Symbols Reference Guide

Introduction to Alchemy Symbols

Alchemy, the ancient philosophical and protoscientific tradition, employed a rich visual language of symbols to represent elements, compounds, processes, and philosophical concepts. These symbols served both practical and esoteric purposes: they functioned as shorthand notation in alchemical manuscripts and reflected the hermetic belief in correspondences between the macrocosm (universe) and microcosm (human body). Dating back to Hellenistic Egypt and flourishing across medieval Europe and the Islamic world, alchemical symbolism combines astronomical signs, geometric shapes, and pictographic representations to communicate the complex principles of alchemical work—from laboratory procedures to spiritual transformation.

The Seven Planetary Metals

Alchemists associated seven primary metals with celestial bodies, establishing foundational correspondences in alchemical work.

The Four Classical Elements

The four elements formed the basis of all matter in both alchemical theory and ancient philosophy.

🜄AirHot & WetDissolution, volatility, intellect
🜃WaterCold & WetSolution, emotion, intuition
🜁EarthCold & DryCoagulation, stability, manifestation
🜀Quintessence/AetherBalance of allThe fifth element, spirit, divine essence

Three Philosophical Principles (Tria Prima)

Introduced by Paracelsus in the 16th century, these principles were considered the true constituents of all substances.
