Sirens

In the Divine Comedy, the Sirens are not encountered as literal monsters but as a symbolic vision that crystallizes the moral psychology of Purgatory. They represent the allure of false goods that can divert the soul from its path toward God, and their appearance serves as a crucial lesson in the purgative process.

The Dream Vision of the Siren

Dante encounters the Sirens in a dream while resting on the Fifth Terrace of Purgatory, where the sin of Avarice is purged. The vision comes at the hour when the diurnal heat can no longer warm the coldness of the moon, and geomancers see their Fortuna Major rising in the orient before the dawn. In this liminal time, a stammering woman appears to Dante: she is squint-eyed, distorted in her feet, with dissevered hands and a sallow hue. As Dante gazes at her, the sun's restorative power seems to act upon her: her tongue becomes voluble, she stands erect, and her lost countenance takes on the colour that love desires. She then begins to sing with such sweetness that Dante can hardly turn his thoughts away from her. She proclaims herself "the Siren sweet / Who mariners amid the main unman," claiming to have drawn Ulysses from his wandering way to her song and asserting that he who dwells with her seldom departs, so wholly does she content him.

The Exposure of the Siren's Deception

The Siren's seductive power is immediately broken by the intervention of a saintly and alert Lady, who appears at Dante's side and sternly calls out to Virgil. The Lady seizes the Siren, rends her garments, and exposes her belly, from which issues a stench that wakes Dante from his dream. This act of unveiling reveals the true nature of the Siren's allure: beneath the beautiful surface lies corruption and decay. The dream thus functions as a moral allegory, teaching that the pleasures of the world, when pursued as ends in themselves, conceal a foul reality that can only be recognized through the aid of divine grace and the guidance of reason and virtue.

The Siren's Thematic Significance in Purgatory

The Siren dream occurs at a pivotal moment in Dante's journey, just before he ascends to the Sixth Terrace. Virgil interprets the vision for Dante, identifying the Siren as "that old enchantress" who alone above them is lamented, and instructs Dante to "smite earth with thy heels" and lift his eyes upward to the lure that the Eternal King whirls with revolutions vast. The Siren thus embodies the temptation to remain fixated on earthly, transient goods—a temptation that the penitent souls on the Mountain of Purgatory must overcome. The dream also echoes the broader structure of the Comedy, where Dante himself, at the very beginning of his journey, found himself lost in a dark forest, having abandoned the straightforward pathway. The Siren represents the kind of false promise that had led him astray, and her exposure reinforces the necessity of the purgative process that strips away the soul's attachment to sin.

The Siren and the Classical Tradition

Dante's Siren draws on classical mythology, where the Sirens were creatures who lured sailors to their doom with enchanting songs. In Homer's Odyssey, Ulysses stops his crew's ears with wax and has himself bound to the mast to resist their call. Dante reimagines this tradition: his Siren claims to have drawn Ulysses from his wandering way, but the context of the dream—and the Lady's intervention—suggests that her power is ultimately illusory when confronted with divine truth. The Siren's boast is undercut by the stench of her exposed belly, revealing that her beauty is a mask for spiritual decay. This transformation of the classical figure into a moral symbol exemplifies Dante's method of using pagan mythology to serve Christian allegory, where the Siren becomes a type of the "old enchantress" of worldly desire that must be recognized and rejected on the path to salvation.
