Cocytus
Cocytus is the frozen lake that constitutes the Ninth and final Circle of Hell, the place where traitors are punished and where Lucifer himself is imprisoned. It is the culmination of Dante's descent, the point of utter cold and stillness that stands in absolute opposition to the warmth and motion of the divine. The lake is formed by the tears of the Statue of Time, which flow down through the infernal rivers—Acheron, Styx, and Phlegethon—and finally collect in this frozen basin, a pool of congealed grief and evil.
Geography and Structure of the Frozen Lake
The lake of Cocytus is not a body of water but a vast expanse of ice, so thick that it resembles glass rather than a liquid. Dante describes it as having a veil of frost so dense that neither the Danube in Austria nor the Don beneath the frigid sky ever formed such a covering; even if the mountains Tambernich or Pietrapana had fallen upon it, the ice would not have given a creak at the edge. The shades of the traitors are fixed within this ice at various depths, their positions determined by the nature of their sin. The lake is divided into four concentric rings, each named for a famous traitor: Caina, for those who betrayed their kindred; Antenora, for those who betrayed their country; Ptolomaea, for those who betrayed their guests and friends; and Judecca, for those who betrayed their lords and benefactors. The entire frozen expanse is overshadowed by the immense form of Lucifer, whose three pairs of bat-like wings generate the winds that keep Cocytus perpetually congealed.
The Punishments of the Traitors
The sinners in Cocytus are punished by the cold itself, a contrapasso that freezes the warmth of human love and loyalty they violated. In Caina, the traitors to their kin are immersed in the ice up to their necks, their heads bowed and their teeth chattering like storks. They are so close together that their hair mingles, and their tears freeze, sealing their eyes shut. In Antenora, the traitors to their country are frozen more deeply, with only their heads above the ice, and they are unable to weep because their tears freeze into a crystal visor that fills the cup beneath the eyebrow. In Ptolomaea, the traitors to their friends and guests lie supine, their faces turned upward, and their tears are frozen in such a way that they cannot even weep, the grief turning inward to increase their anguish. In Judecca, the deepest zone, the shades are completely encased in the ice, visible only as forms within the transparent mass, like straws in glass. The most terrible punishment is reserved for the three arch-traitors whom Lucifer himself eternally devours in his three mouths: Judas Iscariot, who betrayed Christ, and Brutus and Cassius, who betrayed Julius Caesar.
The Encounter with Lucifer
At the very center of Cocytus, at the point where all the weight of the universe converges, Lucifer is fixed in the ice from his mid-breast downward. He is a monstrous giant, far larger than any of the giants Dante saw in the previous circle, and he has three faces: one vermilion, one between white and yellow, and one black, like those from the Nile. Beneath each face, two enormous bat-like wings emerge, and their flapping generates the three winds that freeze Cocytus. From his six eyes, tears and bloody drivel trickle down his three chins. In each of his three mouths, he crunches a sinner: Judas Iscariot, whose head is inside the mouth while his legs kick outside, and Brutus and Cassius, who hang head-downward from the other two mouths. This is the ultimate image of betrayal and its punishment, the point where all evil is concentrated and where the journey through Hell reaches its absolute nadir.
The Ascent from Cocytus
After witnessing Lucifer, Dante and Virgil begin their ascent from Hell. Virgil seizes the moment when Lucifer's wings are open and climbs down his shaggy sides, passing through the ice and the thick hair. When they reach the point where the thigh revolves on the haunch, Virgil turns himself around, reversing his orientation, and begins to climb upward through the opening of a rock. This maneuver brings them past the center of the earth, and they emerge on the other side, now in the southern hemisphere, where they see the stars once more. The frozen lake of Cocytus is thus not only the final prison of the damned but also the pivot point of the entire cosmos, the place from which the journey toward Purgatory and Paradise begins.
Narrative and Thematic Significance
Cocytus represents the absolute negation of love and community, the ultimate consequence of the sin of treachery, which destroys the bonds of trust that hold society and the soul together. The cold that pervades the lake is the opposite of the fire of divine love, and the stillness of the ice is the opposite of the motion of the celestial spheres. The presence of Lucifer, the once-most-beautiful angel who rebelled against God, at the center of this frozen waste underscores the theme of pride and its fall. The journey through Cocytus is the final test of Dante's endurance and faith, and the ascent from it marks the beginning of his purification and redemption. The lake itself, formed from the tears of the Statue of Time, is a symbol of the sorrow that sin brings into the world, a sorrow that is finally overcome only by the grace that leads the pilgrim to the stars.
