The Red Lion is a central symbol in alchemical tradition, representing mastery, transformation, and the culmination of the Great Work, or Magnum Opus. It embodies the fiery energy of life, linked to Rubedo, the final stage of alchemy where opposites are harmonized. The Red Lion symbolizes the integration of raw and refined forces, merging the earthly and the celestial. Tied to the element of fire, Mars, and the Philosopher’s Stone, it signifies spiritual perfection and self-mastery. Its enduring relevance lies in its metaphorical invitation to embrace transformation and achieve harmony within oneself and the universe.
