Magic lantern slides: ghosts, gospel, and proto-cinema on painted glass

Montréal MAY 25 2026

Scroll through eBay's Collectible Magic Lantern Slides category and you get a strange cross-section of the 19th century: hand-painted Bible scenes next to grim Temperance-society warnings, alpine travelogues next to Mickey-era comic strips, single slides for a few dollars next to boxed lecture sets going for hundreds. It looks like a junk drawer. It is in fact the residue of the dominant projected-image medium for roughly 250 years — the thing the cinema replaced.

What you're actually looking at

A magic lantern slide is a piece of glass, typically 3.25 inches square (British standard) or 3.25 × 4 inches (American standard), with an image on it. The image is either:

Hand-painted in oil, watercolour, or varnish-bound transparent pigment ("cold paint") — usually on one piece of glass, sometimes sealed under a cover glass with paper or wood tape binding the edges.
Photographic, after about 1849 — a glass plate exposed by contact or reduction printing from a negative, developed as a positive transparency.
Chromolithographed or printed and then hand-tinted — mass production from roughly the 1820s onward, after Philip Carpenter worked out a copper-plate process for printing slide outlines that could then be coloured by workshop hands.

The fancier slides have moving parts: levers that slide one painted glass over another to make a sleeper open his eyes, a comet cross the sky, a drunkard fall off a stool. The pinnacle of the mechanical form is the chromatrope — two geared glass discs counter-rotating to throw spinning kaleidoscope patterns on a screen. It is, basically, the screensaver, invented in 1844.

Origins: a Dutchman who regretted his invention

The magic lantern shows up in usable form in November 1659, when Christiaan Huygens sketched a skeleton taking off its skull over the note "for representations by means of convex glasses with the lamp." The Jesuit polymath Athanasius Kircher described a similar device around the same time and is sometimes credited as co-inventor, though the Kircher version was almost certainly less developed.

Huygens, who otherwise spent his career on respectable things like pendulum clocks and the rings of Saturn, regretted the lantern almost immediately. In a 1662 letter to his brother he dismissed it as a bagatelle — a trifle — and tried to bury it. Too late. By the end of the 17th century itinerant showmen were already projecting moving slides of a bear mauling a Swiss peasant. The thing he was embarrassed about would outlive him by 280 years.

Phantasmagoria: horror cinema before cinema

The first genuine cultural moment for the lantern was the phantasmagoria — a late-18th-century horror show pioneered by Étienne-Gaspard Robert ("Robertson") in Revolution-era Paris. Robertson worked in a converted Capuchin convent, on smoke instead of a screen, with rear projection so the audience couldn't see the lantern. Skeletons rushed at the crowd. Ghosts dissolved into demons. He'd use multiple lanterns on wheeled trolleys to make figures grow as they "approached." People fainted. There was at least one documented suicide attempt blamed on a show.

This matters because it's the first instance of a medium being used deliberately for jump-scare horror, with the apparatus hidden and the audience encouraged to suspend disbelief in the dark. Everything from the Universal monster films to A24 inherits something from those nights at the Convent of the Capuchins.

The Victorian peak: every parlour, every chapel, every lecture hall

The lantern hit its real cultural saturation between roughly 1870 and 1900. By then the gear had matured — limelight (a literal lump of quicklime heated in an oxyhydrogen flame) gave you enough output for a hall of a thousand people; biunial and triunial lanterns let you stack two or three optical systems to do dissolving views, where one image faded into another. This was projected montage decades before Eisenstein had a word for it.

The slides on eBay are mostly artefacts of this period, and they map onto the four social functions the lantern actually served:

Religion. Sunday-school lecture sets of the Pilgrim's Progress, Old Testament narratives, missionary stories from the colonies. Nonconformist chapels in Britain bought enormous numbers of these. The Salvation Army ran lantern services as outreach.
Education and "improvement." Travel slides — pyramids, Niagara, Jerusalem, the Alps — sold the empire's exotic peripheries to people who would never leave their county. Astronomy slides, anatomy slides, microscope photomicrographs. Every Mechanics' Institute had a lantern.
Moral reform. Temperance slides showing the drunkard's progress from beer to gin to the workhouse. Anti-smoking, anti-gambling, anti-cruelty. The Royal Society for the Prevention of Cruelty to Animals had its own slide sets.
Pure entertainment. Comic slips, Christmas stories, fairy tales, music-hall song slides where the audience sang along to the projected lyrics. The proto-karaoke slide is a real thing.

What the listings on eBay don't always make obvious is that lanterns were also a home medium. By the 1880s you could buy a tin-bodied "toy" lantern in a department store for a few shillings, with a starter set of chromolithographed slides. Middle-class families projected onto a sheet hung in the parlour. The category — cheap printed slides for domestic lanterns — is most of what survives, because it was made in industrial quantities.

Why it died, and why the slides didn't

The lantern didn't die when cinema arrived in 1895. It coexisted. Lecturers kept using lanterns into the 1920s and 1930s because slides were cheap, you controlled the pace, and you could talk over them. Schools used 3.25 × 4 lantern slides well into the 1940s; the format only really died when 35mm Kodachrome and the Carousel projector ate the educational market in the 1950s.

The slides themselves survived in absurd numbers for two reasons. First, they're glass, sealed under cover glass with paper tape. They don't rot, fade fast, or curl the way film does. A Victorian slide kept in a dry attic is in better condition than a 1990s VHS tape. Second, they were mass-produced for nearly a century by big firms — York & Son, Newton & Co., Bamforth, T.H. McAllister, Briggs, the Keystone View Company — so the supply going into the collector market is enormous.

This is why the eBay category is a junk drawer. You can buy a single anonymous chromolithographed comic slide for the price of a coffee, and you can also buy a complete boxed Bamforth narrative set in original packaging for several hundred dollars. The medium was both industrial and artisanal at the same time, and the resale market reflects that.

Why any of it matters now

The interesting thing about magic lantern slides isn't that they're the technical ancestor of the cinema — though they are; dissolving views are cross-fades, chromatropes are abstract animation, phantasmagoria is found-footage horror, song slides are music videos. The interesting thing is that they're the first mass medium where a projected, shared, dark-room image shaped how ordinary people understood the world they couldn't see directly. Empire, scripture, death, faraway cities, the inside of a cell — all of it arrived as a glass square in front of a lamp.

When you look at a tray of slides on eBay, you're looking at the substrate of 19th-century visual imagination. It's the same job YouTube does now, with worse resolution and a much longer service life.
