The 7 Metals of Alchemy and the Planets

The 7 Metals of Alchemy represent the foundational correspondences between the telluric kingdom and the celestial spheres. In the Western Alchemical Tradition, these metals are not merely chemical substances but physical manifestations of planetary energies—the "condensed light" of the wandering stars trapped within the womb of the Earth.

The process of alchemical transformation involves the gradual purification and "exaltation" of these metallic spirits. From the heavy, restrictive influence of Lead (Saturn) to the radiant, perfect sovereignty of Gold (Sun), the metals trace the evolution of the human soul as it undergoes the Great Work. Each metal offers a specific lesson in geometry, resonance, and spiritual refinement.

Below is the complete index of our studies into the seven planetary metals:

• The 7 Metals of Alchemy: 1 - Lead and the Geometry of Saturn
• The 7 Metals of Alchemy: 2 - Tin and the Geometry of Jupiter
• The 7 Metals of Alchemy: 3 - Iron and the Geometry of Mars
• The 7 Metals of Alchemy: 4 - Copper and the Geometry of Venus
• The 7 Metals of Alchemy: 5 - Mercury and the Geometry of Mercury
• The 7 Metals of Alchemy: 6 - Silver and the Geometry of Moon
• The 7 Metals of Alchemy: 7 - Gold and the Geometry of Sun

Seven metals, seven heavens

Ancient and medieval alchemists linked each of the seven metals known to antiquity with one of the seven classical planets:

• Gold (Au): the Sun.
• Silver (Ag): the Moon.
• Mercury (Hg): Mercury.
• Copper (Cu): Venus.
• Iron (Fe): Mars.
• Tin (Sn): Jupiter.
• Lead (Pb): Saturn.

The planetary symbols are still used today, in astronomy and astrology alike. The chemical symbols in parentheses come from modern chemistry, which uses the Latin names for several of them.

Alchemy and chemistry

Alchemy was the ancestor of chemistry. Its experiments contributed to the discovery of acids, alloys, and distillation. Even Isaac Newton wrote more on alchemy than on physics, although he kept most of it private.

A real warning

• Mercury and lead are toxic. Medieval alchemists often fell ill from their own laboratories.
• Never handle them as a hobby. Old thermometers and paints can still contain them.
• Take these correspondences as symbols and history, not as medicine.

Gold was the end of the road. But for many alchemists, the one being refined was the alchemist.

To master the alchemy of the metals is to understand the hidden threads that connect the macrocosm with the microcosm. By aligning our internal state with the vibrational qualities of these planetary signatures, we participate in the ancient art of transmuting the base lead of the ego into the eternal gold of the spirit.
