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.
| Symbol | Name | Planet | Properties | Traditional Uses |
|---|---|---|---|---|
| ☉ | Gold | Sun | Perfection, nobility, incorruptibility | Medicine for heart conditions, symbol of spiritual illumination |
| ☽ | Silver | Moon | Purity, receptivity, flux | Mental disorders, linked to emotions and intuition |
| ♀ | Copper | Venus | Balance, harmony, attraction | Treatments for female ailments, beauty elixirs |
| ♂ | Iron | Mars | Strength, heat, aggression | Blood disorders, strengthening medicines |
| ♃ | Tin | Jupiter | Wisdom, benevolence, expansion | Liver treatments, breath ailments |
| ♄ | Lead | Saturn | Density, stability, melancholy | Chronic diseases, stabilizing preparations |
