Dante's death mask

Dante's death mask is a plaster cast of the poet's face, kept in the Palazzo Vecchio museum, that becomes the central object of a desperate search after Robert Langdon and Ignazio Busoni steal it. The mask conceals a hidden message from Bertrand Zobrist—a spiral poem written in gesso on its reverse side—that leads Langdon and Sienna Brooks first to Venice and then to Istanbul, where Zobrist's plague, Inferno, awaits. The mask is ultimately returned to its display case by Langdon at the novel's end.

Identity and History

The death mask is a plaster cast of Dante Alighieri's face, taken shortly after his death in 1321. It is described as having a "hooked nose and protruding chin" and a "crinkled visage" with closed eyes. The mask is kept in a narrow corridor called the andito of the Palazzo Vecchio museum, displayed in an antique cabinet against the sidewall. Marta Alvarez, the museum's arts and culture administrator, explains that the mask was brought to Florence as a tribute to Dante, who was exiled from the city and buried in Ravenna. The mask is owned not by the museum but by a wealthy patron, the Swiss biochemist Bertrand Zobrist, who purchased it and left it on permanent display. Zobrist's ownership is key: he had private access to the mask and could have written on it without anyone knowing.

Theft and Discovery

On the night before the novel's main events, Langdon and Ignazio Busoni, the director of the Museo dell'Opera del Duomo, steal the mask from its case. Security footage shows Langdon putting on surgical gloves, opening the cabinet, and lifting the mask out while Busoni keeps watch. They place it in a Ziploc bag and hide it in Busoni's briefcase. Busoni dies of a heart attack that same night, but before dying he leaves a voicemail for Langdon saying the mask is "safely hidden" and giving a clue: "Paradise Twenty-five." Langdon, suffering from retrograde amnesia, does not remember the theft. He and Sienna later find the mask hidden in the baptismal font of the Baptistry of San Giovanni, where Busoni had placed it. When Langdon lifts the mask out, he sees it is still sealed in its Ziploc bag.

The Hidden Message

Examining the mask, Langdon notices the back is whiter and rougher than the front, with a "toothy" texture. He realizes it has been coated with acrylic gesso, which is water-soluble. On the gesso, seven identical letters are written: "PPPPPPP." Langdon recognizes this as a reference to Dante's Purgatorio, where an angel writes seven Ps (for peccatum, Latin for "sin") on a penitent's forehead. He wets a cloth and wipes the gesso away, revealing a second layer of calligraphy underneath. The full text is a spiral poem beginning with Dante's line "O you possessed of sturdy intellect" and continuing in Zobrist's imitation of Dante's style. The poem instructs the reader to "seek the treacherous doge of Venice" who "severed the heads from horses" and "plucked up the bones of the blind," then to "kneel within the gilded mouseion of holy wisdom" and listen for trickling water, and finally to "follow deep into the sunken palace" where "the chthonic monster waits, submerged in the bloodred waters of the lagoon that reflects no stars." The poem ends with the word "stars," the same word that ends each of the three sections of The Divine Comedy.

Narrative Role and Significance

The mask functions as the novel's central MacGuffin and puzzle box. It is the object that Langdon and Sienna must find, and its hidden message is the key to locating Zobrist's plague. The mask's theft sets the entire chase in motion, and its recovery and decoding provide the narrative's turning point. The mask also embodies the novel's theme of hidden knowledge: the truth is literally written on the face of the dead poet, concealed beneath a layer of false writing. Langdon's act of wiping away the seven Ps to reveal the true message mirrors the poem's own instruction to "observe the teaching that is hidden here beneath the veil of verses so obscure." At the novel's end, Langdon returns the mask to its display case in the Palazzo Vecchio, restoring it to its proper place.
