Lettres Juives

Lettres Juives is an eighteenth-century epistolary novel whose most consequential role in the book is not its independent plot but its transformation into supposed evidence. Published in 1738 and widely attributed to Jean-Baptiste de Boyer, Marquis d’Argens, it supplied Antoine Augustin Calmet with an account of vampirism that described official investigations, grave exhumations, and the destruction of a suspected vampire. Although the work is now understood to be fictional, readers treated its documentary manner as an authorization of the supernatural, making it a revealing case of how stories acquire institutional force.

Identity and Publication

Lettres Juives was an epistolary novel published in 1738 and commonly attributed to Jean-Baptiste de Boyer, Marquis d’Argens, a French author and religious critic. Its letter-based form helped give the material an air of transmission and testimony: rather than presenting a legend as a simple folktale, it framed extraordinary claims as information passed between correspondents. That literary arrangement mattered because the book’s apparent authority did not depend only on the marvel itself. It depended on the suggestion that the marvel had been reported, checked, and preserved through channels resembling correspondence and official communication.

The novel appeared during a period when European society was unusually receptive to supernatural explanations. The nineteenth century would later become associated with an especially curious mixture of industrial transformation, spiritualism, and belief in witchcraft, but the earlier eighteenth-century vampire craze had already shown how quickly local fears could become public narratives. In eastern Europe, entire villages were reported to have suspected corpses dug up and staked. Against that background, an epistolary account of a vampire investigation could travel between literary entertainment and historical testimony without a clear boundary separating the two.

The Kivsiloa Account

The passage later quoted from Lettres Juives places the alleged incident in Hungary and presents it as duly attested by two officers of the tribunal of Belgrade and an imperial officer at Graditz who claimed to have witnessed the proceedings. In the account, an old man from the village of Kivsiloa died at the age of sixty-two. Three days after his burial, he appeared at night to his son, asked for food, ate what he was given, and disappeared. After the son told his neighbours, the father appeared again two nights later. The next day the son was found dead in his bed, while five or six other villagers suddenly fell ill and died in quick succession.

The local bailiff reported the circumstances to the tribunal of Belgrade, which sent two officers and an executioner to investigate. An imperial officer from Graditz also travelled to the village to observe the examination, presenting the episode as a convergence of local testimony, legal authority, military observation, and ritual action. The story therefore constructs a chain of verification. Its supernatural conclusion is made to seem less like village gossip than the result of an official inquiry.

The investigators opened the graves of people who had been dead for six weeks. The old man’s corpse was described as having open eyes, a fine colour, and natural respiration, although it remained motionless like the dead. From these features the examiners concluded that he was unmistakably a vampire. The executioner drove a stake through his heart, after which the body was placed on a pyre and reduced to ashes. The account added that no mark of vampirism was found on the corpse of the son or on the other dead villagers, preserving a narrow distinction between the alleged source of the contagion and its victims.

Fiction Mistaken for Testimony

The extraordinary force of Lettres Juives lay in the tension between its fictional status and its documentary posture. The novel is now believed to be a work of fiction, yet Calmet was not the only reader who assumed that it recorded fact. The narrative’s references to officers, tribunals, witnesses, graves, physical signs, and an executioner gave it the outward structure of a report. Such details did not merely decorate the story; they supplied a framework through which readers could mistake narrative arrangement for verification.

Antoine Augustin Calmet, a Benedictine monk and renowned academic from Lorraine, quoted the account in The Phantom World, his treatise on angels, demons, spirits, revenants, and vampires. Calmet had been exceptionally well read, wrote extensively on occult mysteries, and was admired by contemporaries; Voltaire is believed to have visited him at his abbey in Senones. His decision to reproduce the Kivsiloa episode placed a fictional account inside a learned discussion and helped extend its authority beyond the novel itself.

Calmet’s use of the passage was more complicated than simple credulity. In a chapter addressing the arguments of the author of Lettres Juives, he declared that there were two ways to eliminate belief in such ghosts: explaining the phenomena through physical causes or denying the stories altogether, with denial being the surest and wisest course. Yet he also recorded the claims at length, including the assertion that they were legally attested by people of probity. The result was an intellectual contradiction with cultural consequences: skepticism preserved and circulated the very narrative it sought to dismantle.

Law, Medicine, and the Supernatural Body

The Kivsiloa story belongs to a wider history in which unexplained deaths and ambiguous corpses were interpreted through competing systems of knowledge. In eighteenth-century Serbia, thirteen deaths in one village in 1731 were attributed by residents to vampire attacks even after a doctor proposed malnutrition as the cause. Exhumed bodies were said to show little decomposition and fresh-looking blood, and Johann Flückinger was sent from Vienna with other doctors and army officers to examine them. The episode shows how medical explanations could coexist uneasily with communal interpretations that identified a dead person as an active agent of further deaths.

Later accounts of blood around a corpse’s mouth or in its stomach could arise from ordinary decomposition. Purge fluid, produced as body tissues break down and pressure forces decaying liquid through the mouth and nose, can appear red-black and be mistaken for blood. Staking a corpse could also release fluids from the body cavities, while gases might have produced a sound interpreted as a corpse’s shriek. These physical processes reveal why the evidence presented in stories like the Kivsiloa account could appear persuasive without requiring a supernatural explanation.

Other corpse phenomena carried similar narrative power. Airtight coffins or heavy clay soil can slow decomposition, while saponification produces adipocere, or corpse wax, through the anaerobic hydrolysis of body fats. The result may preserve facial features and make a corpse look waxen rather than decayed. In a culture without modern knowledge of post-mortem change, such bodies could become material confirmation of revenants. Lettres Juives thus occupies a historical zone in which the body was simultaneously a medical object, a legal exhibit, a religious sign, and a literary device.

Cultural Afterlife and Significance

The novel’s importance extends beyond the Kivsiloa episode because it illustrates a recurring process in vampire history: fear generates a story, the story acquires witnesses and authorities, and later readers mistake those signs of transmission for proof. The same mechanism appears in reports of New England vampire panic, where tuberculosis was interpreted as the dead draining the life force of surviving relatives. In the Mercy Brown case, a corpse’s expected preservation during a cold winter was treated as supernatural freshness, and her heart and lungs were burned in an attempt to save Edwin. The ashes were mixed with water and given to him, but he died on 2 May 1892.

The logic also survives in modern media campaigns. During the Gorbals Vampire panic, the Daily Mirror promoted the idea that imported horror comics had caused children’s hysteria and discussed banning the genre. A confidential government memo later argued that such comics were not legally obscene under the Obscene Publications Act 1857 but were harmful enough to justify stronger powers against their circulation. In both cases, narrative circulation produced institutional reaction: a story did not remain confined to entertainment but helped organize fear, blame, and proposed regulation.

Lettres Juives is therefore significant as an object lesson in the unstable boundary between fiction and knowledge. Its epistolary presentation made an invented account resemble a chain of testimony; Calmet’s learned quotation gave that account a second life as evidence; and the wider history of medical ignorance, corpse transformation, village panic, and press sensationalism supplied an audience ready to believe. The book did not simply preserve a vampire legend. It demonstrates how literary form can manufacture credibility, how credibility can become authority, and how authority can keep an impossible story alive even when its most careful reader argues that the story should be rejected.
