The Regina (Queen) is one of the two royal personae that populate alchemical allegory, paired with the Rex (King) as complementary principles whose marriage, dissolution, and reconstitution drive the drama of the Great Work. In the planetary-metallic correspondence system, the Queen represents Luna (the Moon) and silver, as the King represents Sol (the Sun) and gold. Her elemental qualities are cold and moist — the phlegmatic-sanguine temperament that contrasts with the King's hot, dry, choleric nature.

In the Atalanta Fugiens, the Queen does not appear under a single dedicated emblem but participates in the work's pervasive imagery of gendered opposition and union. The marriage emblems — particularly Emblem IV, with its motto 'Join brother and sister, and hand them the cup with the love potion' — present the Queen as the cold, moist, phlegmatic sister who must be united with her hot, dry, choleric brother. Maier's discourse explains that the brother is burning hot, dry, and choleric while the sister is cold, moist, and phlegmatic, and that their properties correspond to the contradictory elements of fire and water.

De Jong reads the Queen as Maier's figure for the receptive mercurial principle that completes the King's solar fixity. In the coniunctio emblems, the feminine figure receives, contains, and nurtures the active masculine seed — just as silver receives the solar tincture, just as Mercury dissolves and re-forms the Sulphur, just as the earth receives the rain. The Queen's role is not passive in the modern sense but receptive in the Aristotelian sense: she provides the material cause that the King's formal cause requires.

The Queen connects to the broader pattern of feminine figures in the AF — Atalanta, Isis, Venus, Latona, Ceres — all of whom represent aspects of the lunar, volatile, mercurial principle. In Emblem XLIV's grand catalogue, the feminine figures are listed as the lunar counterparts to the solar-masculine pantheon. But the Queen is the most abstract and archetypal of these figures — stripped of specific mythological narrative, she represents the feminine principle itself.

In the Rosarium Philosophorum, which Forshaw identifies as the most likely structural model for the Atalanta Fugiens, the King and Queen appear in a famous series of images depicting their meeting, marriage, copulation, death, decomposition, and resurrection as the Hermaphrodite. Maier draws on this same tradition but distributes the narrative across many emblems rather than concentrating it in a single sequence.

Alchemically, the White Queen represents philosophical Mercury in its purified, lunar aspect — the volatile, moist substance that must be fixed by union with the Red King (Sulphur). The marriage of King and Queen produces the Hermaphrodite (Emblems XXXIII-XXXVIII), and their mutual death and resurrection yields the philosopher's stone. The Queen's whiteness connects her to the albedo stage, while the King's redness connects to the rubedo — their union spans the entire color sequence of the Work.

For a general reader, the Queen represents one half of alchemy's central metaphor: the marriage of opposites. She is everything the King is not — cold where he is hot, moist where he is dry, volatile where he is fixed — and only their union can produce the perfected substance. The alchemical marriage is not a romantic partnership but a chemical reaction, expressed in the language of royal ceremony.

Meanings Across Registers

De Jong shows that alchemical terms operate simultaneously across material, medical, spiritual, and cosmological dimensions.

Alchemical

The White Queen: philosophical Mercury, the lunar-feminine principle whose volatile, moist nature must be fixed and united with the Red King to complete the work.

Medical

The receptive, nourishing aspect of the body's economy; the phlegmatic-sanguine balance that sustains fertility, moisture, and regenerative capacity.

Spiritual

The soul's receptive wisdom; the feminine principle of intuition and contemplation that complements and completes the active masculine will.

Cosmological

The Moon as cosmic consort; the reflective, generative, and cyclical principle that receives solar light and transmits it to the sublunary world.
