Rustico
The DecameronRustico is a young hermit whose encounter with Alibech turns the language of religious devotion into an instrument of sexual deception. He initially presents himself as a teacher of spiritual service, but after yielding to desire he invents a lesson that Alibech accepts literally; the resulting reversal leaves him dependent on the young woman he meant to manipulate.
Identity and Introduction
Rustico lives as a hermit in the Desert of Thebais, where Alibech arrives seeking someone to teach her how to serve God. She is about fourteen, inexperienced, and has left her home in Capsa alone after hearing Christians praise their faith and learning that desert dwellers renounce worldly things. The first holy man she meets gives her food and directs her onward, as does another. Rustico, described as a devout and good young hermit, receives her into his cell instead of sending her away.
His decision is presented as a test of his own constancy. He gives Alibech a bed of palm fronds for the night, but soon finds that his resistance has failed. The account makes the change stark: he abandons prayer and mortification, dwells on her youth and beauty, and considers how to obtain what he wants without appearing to her a debauched man. His religious station and his private intention thus diverge before he begins to teach her anything.
The Deception and Its Language
Rustico first questions Alibech and confirms that she has never known a man and is as inexperienced as she appears. He then fashions a false religious explanation for sexual intercourse. He describes the devil as God’s enemy and tells her that the most acceptable service to God is to put the devil back into hell. When Alibech asks how, he offers himself as the example and stages the act under the appearance of prayer.
The trick depends on Alibech’s sincere effort to follow instruction, not on her recognizing a joke. She accepts Rustico’s account in good faith and consents because she believes the act is a service to God. On their first attempt she feels discomfort and remarks on it; Rustico assures her it will not always be so. The narrator relates that they repeat the act six times before leaving the bed, and that Alibech gradually comes to enjoy what she continues to understand through his invented devotional vocabulary.
That vocabulary then changes hands. Alibech begins returning to Rustico and urging him to resume the supposed service, insisting that she came to serve God rather than remain idle. She also reasons that, if the devil were content to stay in hell, he would not keep escaping. Her remarks expose the gap between Rustico’s euphemism and her literal interpretation, while making her, in practice, the one who repeatedly initiates their encounters.
Reversal and Relationship with Alibech
Rustico’s contrivance produces a reversal he cannot comfortably manage. At first, he directs the encounter and controls its meaning by disguising his desire as instruction. As Alibech becomes more eager, however, he can no longer meet her requests with the same frequency. He lives on roots and water and says that many devils would be needed to quiet her hell; he satisfies her only occasionally, which she considers inadequate service.
The description of Rustico’s dwindling strength sharpens the comic reversal. Alibech’s repeated demands have so lightened his doublet that he shivers when another person would be sweating. He tries to restrain her by revising his doctrine: the devil should be put in hell only when pride makes him rise, and, by God’s grace, theirs has been chastened enough to pray for peace. His explanation is another effort to govern her through the religious fiction he created, but it does not erase the imbalance now driving their relationship: Alibech is willing and persistent, while Rustico lacks the capacity to satisfy her as often as she wants.
Departure and Narrative Significance
Their arrangement ends through events beyond Rustico’s control. A fire in Capsa kills Alibech’s father, his other children, and the rest of his household, leaving her heir to his estate. Neerbale, who has squandered his own property, hears that she is alive and finds her before the authorities can claim the inheritance as the estate of someone thought to have died without an heir. To Rustico’s great satisfaction and against Alibech’s will, Neerbale takes her back to Capsa, marries her, and succeeds to the inheritance through her. The story gives no further account of Rustico after Alibech’s departure.
Rustico’s episode makes religious vocabulary itself part of the plot’s machinery: words meant to describe spiritual service become cover for desire, then are taken up by Alibech as a rule she applies with greater devotion than her teacher can bear. His initial authority rests on her ignorance, but the outcome makes that authority unstable. The comic ending removes Alibech from his cell through marriage and inheritance, without providing a moral conversion or a stated punishment for him; the account leaves his fate unstated while exposing the distance between his profession of devotion and the use he makes of it.
