Hippomenes (sometimes called Milanion in alternate traditions) is the young suitor in Ovid's Metamorphoses, Book X, who wins the hand of the swift-footed Atalanta by using three golden apples provided by the goddess Venus. As Atalanta races ahead, Hippomenes throws the apples one by one, and her curiosity or desire for the beautiful objects causes her to pause, allowing him to reach the finish line first. The couple then consummates their union in the temple of Cybele, provoking the goddess's wrath and their transformation into lions.

In the Atalanta Fugiens, Hippomenes occupies the complementary position to Atalanta as the male, fixed, pursuing principle. He appears on the frontispiece racing against Atalanta at the bottom of the composition, while Venus stands to the right handing him the golden apples. The epigram to the frontispiece identifies the alchemical correspondence: Hippomenes is philosophical Sulphur, the fixed principle that pursues the volatile Mercury (Atalanta) and can only fix it through the mediation of the golden apples (the catalytic art).

De Jong reads Hippomenes as the figure for the disciplined application of alchemical knowledge (De Jong, pp. 314-316). Brute force — outrunning Mercury through sheer speed — is impossible; the volatile principle is inherently faster than the fixed. Only by deploying the apples, which represent the art or technique of the Work, can Hippomenes slow Atalanta enough to catch her. The golden apples' origin in the Garden of the Hesperides connects them to the same treasure that Hercules labors to obtain, placing Hippomenes's victory within the broader tradition of heroic alchemical quest.

In the three-voice fugues that accompany each emblem, Hippomenes's voice represents the pursuing agent, the fixed principle that chases after the volatile. Wescott's modal analysis suggests that the musical structure of each fugue encodes the dynamic relationship between the fixed and volatile principles through the interaction of the three voices. Hippomenes is always pursuing, always behind, always dependent on the golden apple (the third voice) to close the gap.

In Emblem XLIV's comprehensive catalogue of mythological equivalences, Maier lists Hippomenes among the solar-masculine figures that represent aspects of the Philosophical Sun — alongside Osiris, Dionysus, Adonis, Oedipus, Perseus, Achilles, Triptolemus, and Pelops. All are aspects of the same fixed, active, sulphurous principle, expressed through different mythological narratives.

The frontispiece narrative's conclusion — the couple's transformation into lions by Cybele — signals that Hippomenes's victory is not final. Catching and fixing Mercury is only one phase of the Work; the united substance must undergo further transformation. The transition from human lover to lion corresponds to the transition from raw conjunction to the mature, powerful substance symbolized by the alchemical lion.

Alchemically, Hippomenes encodes the principle that Sulphur alone cannot fix Mercury. The golden apples represent the knowledge, the technique, and the catalytic agents that the adept must possess. De Jong identifies Robertus Vallensis's De Veritate et Antiquitate Artis Chemicae as the text that established the hermeneutic precedent for Maier's reading of the race as an allegory for the fixation of the volatile by the fixed.

For a general reader, Hippomenes teaches that intelligence and strategy matter more than raw power in the alchemical art. The adept who tries to fix mercury by brute force will fail; only the one who understands the proper catalytic agents — the golden apples of accumulated wisdom — will succeed in capturing the fleeing substance.

Meanings Across Registers

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

Alchemical

The suitor of Maier's title who arrests Atalanta with three golden apples: figure of the operative artist who fixes volatile mercury through the timely interposition of solar gold.

Medical

The therapeutic intelligence that slows runaway vital spirit by interposing nourishing substances at the right intervals; the physician's art of cadence and dosage.

Spiritual

The contemplative who paces the soul's pursuit of wisdom by deploying compelling images at the right moments; the reader of Atalanta Fugiens as Maier scripts him.

Cosmological

The Sun overtaking the swift Moon at the conjunction; the solar principle whose three apples (gold) successively brake the lunar flight until they meet at the same celestial degree.
