The Eighth Day’s Theme of Deception and Pranks

The Eighth Day’s Theme of Deception and Pranks gives a governing pattern to stories in which women trick men, men trick women, and men trick one another. The reversals are comic, but their stakes are not merely playful: a stratagem can answer an earlier injury, expose a self-serving rule, or turn another person’s confidence into a vulnerability. Across the day, deception becomes both a means of amusement and a way to test who has power to define what counts as justice.

The Day’s Frame and Governing Pattern

The day is announced under the governance of Lauretta as a discussion of tricks played throughout the day among women and men, in every direction. Its storytelling follows the company’s established routine: on Sunday they rise, walk through the dewy grass, visit a nearby church, and return for their customary gathering by the fountain after the sun has passed its height. Neifile begins the day’s tales. The setting places deliberate invention within a shared, convivial practice: these stories are told for an audience that listens together, laughs together, and weighs the designs as they unfold.

The frame also sits within a larger defense of storytelling as consolation. The book’s opening account distinguishes the restricted circumstances of women in love, often confined to their chambers and subject to the wishes of family and husbands, from the many diversions available to men. Stories offer women a form of mental relief and pleasure. The Eighth Day’s tricks give that entertainment an active shape: characters do not merely endure their circumstances but devise ways to alter them, however briefly, through concealment, performance, or a timely reversal.

Requital, Money, and the Price of Trust

Neifile’s story of Gulfardo makes the day’s moral argument explicit. Gulfardo, a German serving the state in Milan and known as a punctual borrower, loves Madam Ambruogia, the wife of his friend Guasparruolo Cagastraccio. The tale’s title describes a bargain in which Gulfardo borrows money, agrees to pay it for Madam Ambruogia’s sexual favors, and then gives the sum to her. In her presence he tells her husband that he has paid her; she confirms the account. The stratagem depends on the husband’s trust in Gulfardo and on the wife’s participation in the claim that the money has changed hands.

The teller distinguishes this episode from ordinary fraud. In her framing, a woman who sells her chastity for money deserves condemnation, while one who yields for love merits a more forgiving judgment; she presents Gulfardo’s trick as a just requital and recalls the case of Madam Filippa. That earlier story concerns a Prato statute that threatened women found in adultery with burning, treating them like women who sold sex. Caught with Lazzerino de' Guazzagliotri, Madam Filippa chooses to appear before the provost rather than flee, and the tale presents her as answering the accusation with courage. The parallel does not make the stories identical: it places private bargains and sexual conduct against public judgments that may be cruel or unequal. The day’s comedy thus asks whose conduct is being condemned, who benefits, and whether a reversal can plausibly be called justice.

A different balance of advantage appears in the story of Salabaetto and Madam Biancofiore. The account introduces a woman in Palermo who artfully strips a merchant of the merchandise he has brought there; the merchant returns pretending to possess still greater quantities, borrows money from her, and leaves water and tow as payment. The story’s setup describes the customs-house records through which brokers learn what goods merchants have brought and how much they own, showing information itself as part of the contest. Where Gulfardo’s plan makes a disputed payment legible to a husband, Salabaetto’s counterplot turns a merchant’s performance of wealth into a means of reclaiming advantage.

Tricks That Recoil and Tricks That Expose

The day’s comic reversals can be harsh. In the story of Calandrino, Bruno, and Buffalmacco, the title identifies a search along the Mugnone for the Heliotrope: Calandrino thinks he has found it, returns home laden with stones, and, when his wife scolds him, flies into a rage and beats her. The episode’s framing presents Calandrino as simple-witted and his companions as shrewd men who enjoy his gullibility. Yet the ending shifts the damage beyond the practical joke: the deceived man directs his anger at his wife, who is not the architect of the trick. Laughter at credulity is therefore shadowed by the consequences of misplaced blame.

The story of Elena and Rinieri makes retaliation the central structure. Elena is a widowed Florentine who chooses not to remarry and secretly enjoys the company of a young man, aided by a trusted maid. Rinieri, a gentleman who has returned from studying in Paris, falls in love with her. The story’s heading supplies the sharp reversal: Elena makes him spend a winter night waiting in the snow; later, through his own stratagem, she is made to remain naked on a tower through a mid-July day, exposed to flies, gadflies, and sun. Pampinea introduces the episode as a just retribution and warns against taking pleasure in mocking others without considering the possibility of revenge. The change of season and bodily circumstance makes the payback visible, while the near-fatal consequence cautions that cleverness does not leave its targets untouched.

Madam Piccarda’s encounter with the rector of Fiesole offers another kind of resistance. A noble widow living near the cathedral, she is young and fair; the rector is old, arrogant, and presumptuous, and his desire does not make him welcome. When he declares his love, Piccarda refuses him, invoking his position as her spiritual father and priest, his age, and the discretion expected of a widow. Here the contest begins not with a completed prank but with an unwanted claim. Her measured refusal exposes the gap between clerical status and conduct, and establishes her as a woman who can answer pressure in her own terms.

Comic Invention and Uneasy Judgment

The Eighth Day’s theme is broad enough to include ingenuity, retaliation, and simple abuse without pretending they are morally interchangeable. Gulfardo’s narrator calls his stratagem a requital; Pampinea treats Rinieri’s revenge as a warning; Calandrino’s anger reveals how a prank can injure someone who did not devise it. The teller of Salabaetto’s story, meanwhile, praises the subtlety of outwitting someone skilled in deception. Each framing directs the audience’s judgment, but the contrasting outcomes keep the day from settling into a single rule that every successful trick is admirable.

Deception also recurs elsewhere in the book in darker forms. Abraham visits the court of Rome and sees churchmen given to lust, greed, and gluttony; rather than concluding that Christianity is false, he interprets its continued growth despite their behavior as evidence of the faith’s divine foundation and chooses baptism. In another episode, Ferondo returns from a drug-induced, deathlike sleep believing that the abbot’s prayers have delivered him from purgatory, and the abbot publicly presents the return as a miracle. These stories are not part of the Eighth Day’s sequence, but they sharpen the distinction between a trick played for comic or retaliatory effect and deception sustained by religious authority. Across the book, false appearances may expose hypocrisy, manipulate belief, or redistribute power; the Eighth Day makes that instability its organizing pleasure.
