In January 1798, a notice for Étienne-Gaspard Robert’s Fantasmagorie at the Pavillon de l’Échiquier in Paris promised apparitions of spectres and revenants, experiments with the new fluid called galvanism, and a distinguished artist at the glass harmonica.
Robert performed as Robertson. He was a Liège-born physicist, showman, and later balloonist who had studied the older literature of the magic lantern, including Athanasius Kircher, and had watched rivals. Paul Philidor had already been selling a “Phantasmagorie” in the early 1790s. Robertson did not invent the hunger. He industrialized the dark.
The first public home of his refined show was not a crypt. It was a pavilion. After police attention, a shutdown, a Bordeaux interlude, and a quarrel with assistants who had kept performing without him, he reopened in a more theatrical ruin: the former Convent of the Capuchines, from early 1799, near what Parisians were still learning to call the Place Vendôme. There the architecture finally matched the advertisement. Stone, tombs, a corridor, a room that could be made to forget it had ever been used for anything but waiting.
What the audience was not supposed to see, in either venue, was the machine.
A Lantern That Had Been Too Honest
Christiaan Huygens described a working laterna magica around 1659: a lamp, a reflector, a lens, a painted glass. For more than a century the device was a traveling companion, the wooden box of the savoyard, good for comic slides, Bible pictures, and astronomy. It had a structural honesty problem. The lantern sat in the room. You could smell the lamp. You could watch the showman change the slip of glass. The picture on the wall kept a rectangular border, a little glowing postcard that never forgot it was a postcard.
Robertson’s wager, shared with the better of his competitors, was that terror needs the postcard to disappear. Put the lantern behind a translucent screen. Paint the slide’s ground so black that only the figure carries light. Then the white rectangle dies, and the mind has no wall to attach the ghost to.
His 1799 patent described a large walnut apparatus, several feet high, closed like a small room, with a square tube for the lens. He called the wheeled instrument a Fantascope or Fantoscope, depending on the document. The useful parts are easier than the name. Rails or a guided path let the whole box roll toward the screen or away from it. As the throw distance changed, the operator had to keep the image sharp. Robertson linked focus to the travel so that a figure could swell as if it were coming through the air, not as if a postcard were being enlarged.
A diaphragm, the so-called cat’s-eye, could starve the lamp. Combined with the blacked-out ground of the slide, a skeleton could be born from empty dark and returned to it. Rear projection is the whole trick and none of the romance. The romance is what the audience does when the trick works.
Glass That Moves, Smoke That Thickens
A still slide can startle. A slide that changes can hold.
Phantasmagoria glasses were painted in mineral colors on plate, then housed in frames with tabs, levers, and sometimes gears. A slipping slide is two layers. Pull the brass and a closed eye becomes an open one, or a face becomes a skull. Lever work can send a painted gaze traveling. Rotary discs can flutter a wing. These are not cinema frames. They are mechanical comics, one transformation at a time, timed to music and to the lantern’s approach.
Smoke is the other amplifier, and here a writer has to stay honest. Period accounts and later reconstructions agree that showmen used vapor and incense so that light would catch in volume instead of dying on a flat linen. Robertson’s own memoirs, mediated and self-serving, like to linger on atmosphere. What can be said without inventing a recipe is that a beam in particulate air stops looking like a drawing pinned to cloth. It looks like a body with weather inside it. People swung at it. That part of the legend is consistent because it is psychologically cheap. If you cannot find the surface, you try to find the volume with a cane.
Sound did advertised work. The glass harmonica, Franklin’s instrument of spinning bowls, is named on the 1798 bill. It produces a thin, continuous cry that sits in the teeth. Thunder sheets and speaking tubes belong to the same family of stage carpentry that later haunted houses never abandoned. Galvanism on the program is a period signature: the new electricity as a cousin of resurrection, shown in the same evening as the ghosts, so that science and superstition could rent the same dark.
After the Convent
Robertson kept the Capucines shows running for years, then took the act on the road, including a famous Russian passage. In London, Paul de Philipsthal presented phantasmagoria at the Lyceum in 1801. The fashion moved the way fashions do. Once everyone knows the lantern is behind the sheet, the sheet has to work harder.
The lineage into later media is real and should be kept modest. Méliès came out of theatrical illusion, including the Robert-Houdin house, and carried lantern habits of superposition and dissolve onto film. He did not “steal” Robertson so much as inherit a problem every illusionist already had: how to make a figure appear without a wooden frame around it. John Henry Pepper’s ghost, in the 1860s, is a different optical contract: a live actor and a hidden reflection sharing a stage. Theme-park dark rides still combine a vehicle path, a sudden change of scale, blackout, and sound from the wrong direction. Disney’s Haunted Mansion is not a copy of Robertson. It is a descendant of the same problem: how to make a paying crowd accept that the dark is occupied.
Chiaroscuro in gothic cinema inherits the architectural half of that problem. In-camera shadow inherits the practical half. Optical illusion as a wider craft includes Pepper and the lantern both. This page’s job is the evening when the projector learned to hide.
Robertson died in 1837, leaving Mémoires that are as much performance as record. The Fantascope in collections, including the walnut veteran associated with the Conservatoire, is more trustworthy than any single ghost story he told about a night in the convent.
The useful image is not a demon. It is a closed box on wheels, a painted glass with the sky blacked out, and an operator walking backward so that a figure can grow. Cinema is what happens when that walk is replaced by a strip of time. The fear, if the room is dark enough, does not notice the difference at first.
