The Public Dissection of the Sea Monster at Versailles is a court-sponsored anatomical demonstration in which the dead male creature is opened before Louis XIV while the surviving female remains within hearing of the proceedings. Its decisive tension is between the dissection’s public claims to knowledge and the living sea monster’s cries: the audience can watch a body become an object of study, but cannot make its audible response disappear. The event ends not with a completed account of the anatomy, but with the King’s order to publish Yves de la Croix’s notes and sketches and commission a medal.

Royal staging and preparation

The demonstration is organized around the King’s convenience. Before the procedure begins, two lackeys remove ice and insulating sawdust from the dissection table, uncovering the shrouded body. Other attendants hold large mirrors so Louis XIV can follow the work without craning his neck. A surgical theater in Paris might have served the other spectators better and allowed more people a clear view; at Versailles, however, the arrangement favors the sovereign. Scientific observation takes place inside the court’s hierarchy, and even the tools for seeing are positioned to accommodate royal authority.

Marie-Josèphe de la Croix stands ready at her drawing box, which contains paper, charcoal, and pastels. Drawing had been forbidden to her at the convent in Martinique, and she had lacked time to practice at Saint-Cyr. She nevertheless hopes to do justice to Yves’s work. Her assigned task makes her a recorder as well as a spectator: while the dissection proceeds, she sketches the creature’s body, leg, and webbed, clawed foot, until her hand cramps. The sequence of drawings accumulates across the frame, giving the demonstration a visual record even as the King later orders that Yves’s notes and sketches be published.

The setting gathers different kinds of attention around the table. Chartres watches eagerly, intent on capturing whatever knowledge Yves offers; Marie-Josèphe briefly imagines his eagerness extending to the menial work of removing ice or holding a mirror. The quartet’s familiar music provides a courtly frame, but that frame proves unstable. Madame, an accomplished musician herself, reacts when the music seems to depart from its expected course, and even Louis XIV glances toward the players. The musicians have not changed the piece: the sea monster’s voice has risen above it, then dropped below it, its low rumble felt by Marie-Josèphe as a chill.

Opening the body

Yves presents the dissection as a staged progression. He says he will begin with a gross dissection, proceeding through the creature’s skin, fascia, and muscles, then pulls the canvas aside. The male sea monster is coarser-featured than the female, with pale-green, tangled, uneven hair. Its appearance does not shock Marie-Josèphe, who has helped Yves dissect frogs, snakes, wharf-rats, worms, and sharks. For her, the sight belongs to a practice of examination; for the assembled court, the dead body is also a spectacle.

The contrast between the two creatures is established before the cutting begins. Yves declares that Louis XIV’s resources enabled him to find the yearly gathering place of the last sea monsters and capture two alive. He says the male resisted until death, while the female survives because, in his account, she lacks the same will to freedom. That assertion is Yves’s explanation, not an independent finding established by the scene. Its language nevertheless exposes a conflict built into the demonstration: the captured female’s continued life is presented as evidence about her character even as her captivity prevents her from acting freely.

When Yves makes the first incision, cutting the dead creature’s skin from sternum to pubis, the female sea monster screams. The musicians play louder in an attempt to drown out the shrieks, but fail. Yves raises his voice over both music and cries to explain that the skin is thick and leathery, offering protection from predators such as sharks, whales, and kraken. He points to the tail’s especially thick, heavily armored skin as evidence that the creature’s defense is escape. The explanation is anatomical and functional, yet the female’s cry interrupts its orderly delivery: the body on the table is being interpreted as evidence while another member of its kind audibly responds.

The living creature and the court

The dissection does not silence the female throughout. Servants take down the sides of a silken tent and fasten the material to the bars of her cage, placing a thin curtain between her and Louis XIV. Marie-Josèphe recognizes the limits of the expedient: the silk will hardly block the sound and will not make enough darkness for the creature to sleep. Heavier canvas cannot be fetched from Versailles town within an hour, or from Paris in less than a day. The intervention is improvised, constrained by time, and aimed at separating the royal audience from the captive without truly isolating her.

After the silk is hung, the cries fade. The crowd, with the King as the exception, turns toward the cage in surprise; whistles give way to quiet, and relief passes among the spectators. Lucien de Barenton, Count de Chrétien, gestures for the servants to resume their places and bows toward Marie-Josèphe. She returns an uncertain smile, unable to know whether her suggestion caused the silence or whether it is coincidence. The menagerie’s answering roars also taper off, ending with a tiger’s hoarse cough. The sequence links the cage, the gathered animals, and the court’s attempt to contain sound, but it does not establish why the female becomes quiet.

The quartet softens, Yves resumes his lecture, and Marie-Josèphe returns to her sketches. Louis XIV watches the dissection of the chest and shoulder muscles with interest. Once Yves announces that he will next expose the internal organs, the King speaks to Lucien, who signals for the royal deaf-mutes to take their places. The seated courtiers rise in a rush of silk and satin. The scene’s attention shifts again from the body under examination to the forms of access and service surrounding the King.

Publication and aftermath

At the close of the observed proceedings, Louis XIV tells Lucien to order the French Academy of Sciences to publish Father de la Croix’s notes and sketches and to commission a medal. The command turns the demonstration into an officially sponsored record and commemorative object. Yves’s account will travel beyond the tent through publication, while the medal will give the event a royal form of remembrance. The King also tells Yves that Lucien will inform him when he is free to observe again, adding that the Pope might wish to attend. The dissection is therefore presented as a continuing undertaking rather than a finished inquiry; the excerpt does not establish the results of the later examination.

After Louis XIV leaves, the musicians follow him, still playing, and the court, servants, guards, and visitors depart. Marie-Josèphe remains with Yves and Lucien. She sits only after the royal departure, choosing a chair still warm from the Chevalier de Lorraine rather than the King’s seat, which etiquette makes unavailable to her. Her charcoal-smudged riding habit and painfully pinching new shoes bring the elaborate public occasion back to her own tired body. The demonstration has moved from royal spectacle to official scientific record, but its ending leaves the most unsettled presence beyond the table: the living female, whose cries briefly broke through the music and the language of dissection.
