The Great Work

Magnum Opus — the central work of alchemy

Alchemy is a historical discipline that sought the transmutation of base metals, alongside aims in medicine, longevity, and the preparation of potent remedies.

The Great Work, or Magnum Opus, is the ordered labor upon prima materia toward the philosopher’s stone, the substance believed to perfect metals and yield an elixir of life.

The Work in Four Colors

Nigredo

The blackening initiates the work. Matter is broken down, impurities are separated, and the fixed is brought to a state of dissolution.

It is a disciplined descent into the raw, where form is loosened so that it can be re-formed.

Keynotes: Blackening · Putrefaction · Dissolution · Separation

Albedo

The whitening follows with cleansing and clarification. The mixture is purified, and the volatile is refined into a clearer substance.

This stage steadies the work and prepares the material for a higher union.

Keynotes: Purification · Clarification · Washing · White

Citrinitas

The yellowing signals dawning maturity. The work gains warmth and coherence as the substance moves toward a solar clarity.

It is the stage of illumination, where the matter is made ready for completion.

Keynotes: Yellowing · Illumination · Maturity · Solar

Rubedo

The reddening is the culmination. The work reaches its fixed, unified form and the elements are reconciled.

It marks completion, when the substance is fully integrated and stabilized.

Keynotes: Reddening · Completion · Integration · Fixation
