Adonis is the dying god of Near Eastern and Greek mythology, a figure of extraordinary beauty born from the incestuous union of Myrrha and her father Cinyras, king of Cyprus. In the Ovidian tradition that Maier draws upon, Venus falls in love with the youth, but he is killed by a wild boar during a hunt. Venus, rushing to aid him, wounds her foot on a thorn, and her blood stains the white roses red. The myth encodes a seasonal cycle: Adonis spends six months with Proserpina in the underworld and six months with Venus above, mirroring the agricultural rhythm of sowing and harvest.

In the Atalanta Fugiens, Adonis appears centrally in Emblem XLI, whose motto reads: 'Adonis is killed by a boar, and Venus, rushing up to him, painted the roses red with her blood.' The epigram specifies the incestuous origin, opening with the line: 'From her own father, Myrrha received the beautiful Adonis.' The plate depicts the narrative sequence of the hunt, the boar's attack, and Venus's grief. In the discourse, Maier explicitly rejects the standard mythological interpretation connecting Adonis with the common sun or with plant seeds, insisting instead on an alchemical reading.

Maier identifies Adonis as the Philosophical Sun, not the celestial sun but the solar principle within the alchemical work. He cites Orpheus as authority that Adonis has 'several names and is boy and girl at the same time,' establishing the figure's hermaphroditic character. The discourse equates Adonis with Dionysus, Sol, and Osiris of Emblem XLIV, making him one of several mythological guises for the same philosophical substance. His death by the boar represents destruction by a corrosive acid or dissolving liquid, while Venus's coloring of the roses traces the color transition from white to red.

Alchemically, the Adonis narrative encodes the putrefactio and the subsequent color change that signals progress in the Work. De Jong reads the incestuous birth as Maier's expression of the fundamental alchemical principle that all manifestations emerge from one primary matter, making all differentiations ultimately related to a single origin (De Jong, pp. 264-266). The killing by the boar represents the stage of putrefaction, where the Lapis Philosophorum is 'killed in the first instance.' The love of Venus and Adonis then enacts the transition from whiteness (the white roses, albedo) to redness (the tinctura rubea, rubedo), as Venus colors the roses red with her blood.

Maier further develops the parallel between Adonis and Osiris: both are killed violently, both are mourned with annual rites of lamentation followed by celebration of resurrection, and both encode the same alchemical cycle of death and renewal. The Belinus metaphor in the Rosarium Philosophorum provides Maier with Sol's speech about his own dismemberment and reconstitution, which he applies to the Adonis narrative. De Jong notes that the discourse connects the story to Emblem XII (Saturn) and to the broader pattern of incestuous unions that recurs throughout the second half of the work.

For a lay reader, Adonis represents one of several mythological figures Maier uses to dramatize the idea that something precious must be destroyed before it can be perfected. The beauty that Venus loves must die violently, be mourned, and then, through the goddess's own sacrifice of blood, achieve a transformation from white to red — the alchemist's code for the final stages of producing the philosopher's stone.

Meanings Across Registers

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

Alchemical

The beautiful youth slain by the boar: an allegory of the precious substance destroyed in the violent phase of the work, whose blood (tincture) colors the white rose red.

Medical

The principle of youthful vitality cut short by violence or disease; the transience of bodily beauty that must be preserved through the physician's art.

Spiritual

The dying and rising god of desire; the soul's attachment to sensory beauty that must be sacrificed before resurrection into a higher, imperishable form.

Cosmological

The annual vegetation cycle embodied: Adonis's death in autumn and rebirth in spring mirrors the cosmic rhythm of solar withdrawal and return.
