Penitenziagite

Penitenziagite is a distorted, vernacular rendering of the Latin "Penitentiam agite" ("Repent ye"), the opening words of John the Baptist's preaching in the Gospels. In the novel, it is first spoken by the misshapen, multilingual monk Salvatore when he accosts William and Adso outside the abbey church. Salvatore's garbled cry—"Penitenziagite! Watch out for the draco who cometh in futurum to gnaw your anima!"—immediately marks him as a creature of the margins, his speech a Babelish patchwork of Latin, Provençal, and other tongues, reflecting his rootless, vagabond past. William, hearing the word, at once suspects Salvatore's connection to the radical Franciscan offshoots, asking him directly whether he has lived among the "so-called apostles." Salvatore's fearful reaction—blanching, blessing himself, and fleeing—confirms William's suspicion that the word is a shibboleth of the heretical movements that had swept northern Italy decades earlier.

Origins and Heretical Associations

The cry "Penitenziagite" is explicitly linked to Gherardo Segarelli, the founder of the Apostolic Brethren in Parma in the late thirteenth century. Ubertino of Casale, recounting the history of heresy to Adso, explains that Segarelli "began preaching, exhorting all to a life of penitence, and he would go along the roads crying 'Penitenziagite!'—which was the uneducated man's way of saying 'Penitentiam agite, appropinquabit enim regnum coelorum.'" Segarelli's movement, which demanded absolute poverty and apostolic simplicity, was condemned by the Church, and Segarelli himself was burned at the stake in 1300. His disciple Fra Dolcino took up the same cry and led a far more violent rebellion in the mountains of Novara, gathering thousands of followers who lived in promiscuity and waged war against the clergy and feudal lords. The word thus becomes a verbal emblem of the entire tradition of radical, often apocalyptic, penitential heresy that the novel explores.

William's Investigation and the Cellarer's Confession

William's alertness to the word proves crucial. When he hears Salvatore utter it, he immediately connects it to the Spiritual Franciscans and the Apostolic Brethren, a connection that later deepens when he interrogates Salvatore about his past. Under pressure, Salvatore confesses that he and the cellarer, Remigio of Varagine, had been followers of Fra Dolcino on Bald Mountain, and that they had fled together after the movement's defeat. The word "Penitenziagite" thus becomes a thread linking the abbey's present crimes to the violent history of heresy. During Bernard Gui's trial of Remigio, the cellarer's confession is punctuated by the same cry: he admits that he and his fellow Dolcinians "went through villages and seduced people crying 'Penitenziagite,'" using the call to draw crowds and legitimize their looting and violence. The word, originally a summons to repentance, is thus perverted into a battle cry for destruction.

Thematic Significance: The Ambiguity of Penitence

"Penitenziagite" encapsulates one of the novel's central themes: the dangerous proximity between authentic religious fervor and heretical excess. The call to repentance, which should lead to humility and conversion, becomes in the mouths of Segarelli and Dolcino a justification for social upheaval, violence, and the rejection of all ecclesiastical authority. William reflects on this paradox when he tells Adso that "the great age of penitence is over" and that the preachers of his own day, by using fear of hell to control the simple, have replaced true repentance with a "penitence of the imagination." The word "Penitenziagite" thus marks the point where the Gospel's call to metanoia is twisted into a tool of fanaticism, a theme that resonates throughout the novel's exploration of the relationship between faith, power, and violence. The word's final appearance in the text comes during Remigio's trial, when he confesses to having used it to seduce crowds, and it is immediately followed by his descent into a litany of demonic names, a grotesque parody of prayer that seals his condemnation. The cry that began as a summons to the kingdom of heaven ends as a prelude to the stake.
