Lasciate ogne speranza, voi ch’entrate

Lasciate ogne speranza, voi ch’entrate — "Abandon all hope, ye who enter here" — is the most famous line in all of Dante Alighieri's Inferno, the first part of The Divine Comedy. In Dan Brown's novel Inferno, this medieval inscription is not merely quoted as a literary reference but becomes a literal, terrifying soundscape that marks the story's climactic descent into a real-world hell. The line is chanted by the chorus of the Istanbul State Symphony Orchestra during a performance of Franz Liszt's Dante Symphony inside the Yerebatan Sarayi, the ancient subterranean cistern in Istanbul, at the precise moment Robert Langdon and Agent Christoph Brüder descend into the space to find Bertrand Zobrist's plague. The phrase thus functions as a direct, diegetic warning that the characters have entered a space of genuine, manufactured damnation.

Origin and Meaning in Dante's Work

The line originates from Canto III of Dante's Inferno, where it is inscribed above the gates of hell. In the poem, it serves as the threshold warning for all who would enter the underworld, signaling the absolute finality and hopelessness of the damned. The phrase is so iconic that it has become synonymous with the entire concept of hell in Western culture. In Inferno, the novel, this cultural weight is exploited to its fullest: the line is not just a quotation but a structural and thematic anchor. The novel's prologue, narrated by the Shade (Bertrand Zobrist), echoes the poem's opening, and the entire plot is a modern-day descent into a manufactured inferno. The line's appearance at the climax is therefore a return to the source, a moment where the literary metaphor becomes physical reality.

The Performance in the Cistern

The line is performed by the Istanbul State State Symphony Orchestra as part of a week-long series of free concerts of Liszt's Dante Symphony, which was underwritten by an anonymous donor — strongly implied to be Zobrist himself. The concert is held in the Yerebatan Sarayi, a vast, columned underground water cistern that has been converted into a tourist attraction and cultural venue. The cistern is described as a "subterranean cavern" bathed in red light, with a glassy sheet of dark, still water — the "lagoon that reflects no stars" from Zobrist's poem. As Langdon and Brüder descend the stairs, the warm, humid wind from the cistern carries the sound of the orchestra and chorus. The choir's chanting of "Lasciate ogne speranza, voi ch’entrate" wells up from the bottom of the stairs "like the ominous stench of death," accompanied by a swell of trumpets and horns. The performance is not background music; it is a deliberate, theatrical announcement that the characters are entering a space of manufactured damnation.

Thematic Significance: Hell as a Constructed Space

The use of this line at the climax of the novel underscores a central theme: that hell is not a supernatural realm but a human-made catastrophe. Zobrist, a genetic engineer and Dante fanatic, has created a literal plague called Inferno, designed to render one-third of the human population sterile. He has chosen the Yerebatan Sarayi as the release point, and the concert series is a mechanism to ensure maximum exposure. The chanting of Dante's line is therefore not a metaphor but a literal description of the space the characters have entered. The cistern, with its red-lit columns and still water, is a physical recreation of Dante's vision of hell, and the plague is the modern equivalent of divine punishment. The line serves as a bridge between the medieval poem and the contemporary bioterrorism plot, suggesting that the horrors of the Inferno are not confined to literature but can be engineered by human genius and madness.

The Moment of Revelation

For Langdon, the sound of the chorus is a moment of profound recognition. He has been haunted by visions of Dante's hell all day, and now he is standing in a physical space that mirrors those visions. The line "Abandon all hope, ye who enter here" is no longer a literary quotation but a direct address to him and Brüder. The novel uses the line to create a powerful sense of inevitability and dread. The characters have been racing against time to prevent the release of the plague, but the concert's week-long run reveals that they are too late: the Solublon bag containing the virus has already dissolved, and the contagion has been in the air for days. The chanting of the line is thus a confirmation of their failure, a musical announcement that the hell they feared has already arrived.

The Line as a Structural Echo

The line also echoes the novel's own opening. The prologue, narrated by the Shade, ends with the words "I whisper my amen … and take my final step, into the abyss." The novel's climax, with the chorus chanting Dante's warning, brings the narrative full circle. The Shade's suicide is the first step into the abyss; the concertgoers' inhalation of the virus is the collective step. The line thus functions as a structural marker, signaling that the descent into hell, which began with Zobrist's jump from the Badia tower, has now been completed by the entire audience. The novel's use of the line is therefore not decorative but integral to its architecture, a way of mapping the modern thriller onto the medieval epic.
