Fra Alberto and Lisetta's Angel Gabriel Deception and Affair
The DecameronFra Alberto and Lisetta's Angel Gabriel Deception and Affair turns a clandestine liaison into a public exposure of religious hypocrisy: Fra Alberto uses his standing as a priest to make Lisetta da Ca' Quirino believe that their sexual encounters are visits from the Angel Gabriel. The affair depends on two performances—the friar's feigned holiness and the angelic disguise he assumes for Lisetta—and ends when her pride makes their secret public, leaving him exposed and humiliated in Venice.
A confession becomes an opportunity
Fra Alberto's reputation as a holy man conceals a life of persistent wrongdoing. Though he had been a thief, pimp, forger, and killer, he became a priest and cultivated a public image of sanctity through preaching and tears at the altar. The Venetians trusted him with wills and money and sought him as confessor and counsellor; his fame for holiness, the narrative says, surpassed that of Saint Francis at Assisi. This contrast between office and conduct establishes the authority he will exploit.
Lisetta da Ca' Quirino, a young and vain woman, comes to confess with other ladies while her merchant husband is away with the galleys in Flanders. When Fra Alberto asks whether she has a lover, she answers by boasting that her beauty could attract lovers in abundance, though she is too distinguished to give herself to just anyone. The friar recognizes her vanity as an opening. He rebukes her for conceit, but the rebuke disguises his own desire: he has fallen in love with her and is waiting for a chance to approach.
After several days, Fra Alberto visits Lisetta's house with a trusted companion and speaks with her in private. He asks her to forgive his earlier rebuke, claiming that the Angel Gabriel appeared to him that night, beat him for disparaging her beauty, and ordered him to seek her pardon. The story turns Lisetta's boast into supposed heavenly testimony. She believes him, forgives him, and presses him to disclose the rest of the angel's message.
Fra Alberto then claims that the Angel Gabriel loves her and wishes to spend a night with her in human form, since an angel in angelic form could not be touched. He tells her that the angel will enter using Fra Alberto's body: the friar's soul will go to Paradise while the angel occupies his flesh. Lisetta accepts this account as a privilege rather than a deception. She agrees to be alone in her chamber and to leave the house door open, giving Fra Alberto the access he needs.
The disguise and the affair
Fra Alberto prepares for the encounter as an adulterous lover, not as a messenger from Heaven. He fortifies himself with confections and other food, then goes first to the house of a woman friend, where his companion can remain. When night comes, he disguises himself in angelic trappings and enters Lisetta's chamber dressed in white. She kneels before the apparent angel; he blesses her, signals her to get into bed, and lies with her. He also speaks to her about the glories of Heaven, keeping the spiritual fiction in place while he pursues the bodily affair.
At dawn he takes away his costume and returns to his companion. Lisetta visits him later that day and recounts the angel's supposed revelations. Fra Alberto sustains the fiction by claiming that, while the angel was with her, his own soul had been carried to a place filled with roses and other flowers. When she tells him that his body had lain in her arms and points to a kiss-mark beneath her left breast, he pretends that this confirms the angel's visit. The physical evidence of the affair is thus folded into the deception rather than allowed to challenge it.
Fra Alberto returns to Lisetta repeatedly in angel form, and the arrangement continues without interruption until she betrays the secret. In an argument with a female acquaintance about women's beauty, Lisetta hints that her own charms are desired by someone beyond comparison. The acquaintance encourages her to say more. Lisetta then identifies the Angel Gabriel as her lover and claims that he often comes to lie with her, adding that he is a better bedfellow than her husband. Her boast transforms a secret sustained between two people into a story for others to repeat.
Exposure in Venice
Lisetta's acquaintance repeats the tale at a gathering of ladies. It passes from them to their husbands and onward through other households, so that within two days the story has spread throughout Venice. Among those who hear it are Lisetta's brothers-in-law. They do not confront her immediately; instead, they watch for several nights, hoping to catch the supposed angel. When Fra Alberto comes to Lisetta's house one night, they see him arrive and move to open her chamber door.
Fra Alberto hears them and understands that he is trapped. He escapes through a window facing the Grand Canal and plunges into the water. Because he can swim, he reaches the opposite bank unharmed and takes refuge in an open house, where he begs a poor man to hide him. He is naked, and his explanation for appearing there at that hour is a story of his own invention. The man leaves him in a bed while he attends to his business.
The brothers-in-law enter Lisetta's chamber but find that the Angel Gabriel has flown, leaving his trappings behind. They berate her and take the costume away. Meanwhile, the man sheltering Fra Alberto hears at the Rialto that the angel has escaped into the canal and concludes that the naked friar in his house is the fugitive. He secures fifty ducats from Fra Alberto in return for not giving him up, then proposes a further disguise as the only apparent means of escape.
From angel to wild man
A festival is being held in St. Mark's Place, where people bring costumed figures as part of a public hunt. The man smears Fra Alberto with honey, covers him with down, puts a chain around his neck and a mask over his face, and gives him a staff and two dogs. He then announces that the Angel Gabriel can be seen at St. Mark's Place. Fra Alberto is led through the city as a wild man, drawing a crowd that follows the spectacle to the festival.
Once the crowd has gathered, the man ties Fra Alberto to a raised column and removes his mask, announcing that this is the angel who comes down from Heaven at night to comfort Venetian ladies. The revelation reverses the performance Fra Alberto had used on Lisetta: the angelic identity is now a public joke, and the friar is displayed as a captive. The crowd recognizes him, insults him, and throws filth at him. His brethren eventually arrive, unchain him, cover him with a gown, and carry him back to the convent amid a general outcry. The narrative reports that he was believed to have died in prison after a wretched life.
Lisetta remains disconsolate after her brothers-in-law take the angel's costume and leave her. Fra Alberto's exposure is not simply the end of a private affair: it reveals how his clerical reputation made his deception possible, while his punishment converts the borrowed signs of holiness into instruments of shame. The man who claimed that his soul was in Paradise is finally remembered for the gap between his sacred appearance and his conduct.
