The first known document concerning the magic lantern is a page on which Christiaan Huygens made ten small sketches of a skeleton taking off its skull, above which he wrote for representations by means of convex glasses with the lamp. This page was found between documents dated in 1659, suggesting the invention occurred in that same year, yet Huygens himself soon regretted the creation. He considered the device too frivolous and feared it would harm his family's reputation if people discovered the lantern came from him. In a letter to his brother Lodewijk in 1662, he dismissed the invention as an old bagatelle and even asked Lodewijk to sabotage the lantern before it could be shown to the court of King Louis XIV at the Louvre. Despite this initial rejection, the device would evolve from a family secret into a global phenomenon that would haunt and educate audiences for three centuries. The core mechanism relied on a simple optical truth: a single lens inverts an image projected through it, meaning slides had to be inserted upside down to render the projected image correctly oriented. This inversion principle, known since the time of the camera obscura, became the defining technical challenge that inventors had to overcome to create a functional projector.
The Dane and The Jesuit
While Christiaan Huygens is often credited with the invention, the history of the magic lantern is a tangled web of competing claims and parallel developments across Europe. A separate early tradition seems to have been developed in southern Germany, including lanterns with horizontal cylindrical bodies, while Huygens and the Dane Thomas Walgensten both used vertical bodies. Walgensten, a mathematician from Gotland, studied at the university of Leiden between 1657 and 1658, possibly meeting Huygens and learning about the lantern from him. From 1664 until 1670, Walgensten demonstrated the magic lantern in Paris, Lyon, Rome, and Copenhagen, selling so many lanterns to Italian princes that they became almost everyday items in Rome by 1671. He is credited with coining the term Laterna Magica, which Claude Dechales published about seeing the machine of the erudite Dane in 1674. Meanwhile, German Jesuit scholar Athanasius Kircher had described a primitive projection system in his 1645 book Ars Magna Lucis et Umbrae, known as the Steganographic Mirror. Kircher used a concave mirror reflecting sunlight to project text or pictures, mostly intended for long-distance communication. He expressed hope that someone would find a method to improve on this, and Walgensten is thought to have reworked Kircher's ideas into a better lantern. The connection between these figures remains murky, with some reports suggesting that the Belgian Jesuit mathematician André Tacquet, a friend of Huygens, may have been an early adapter of the technique Huygens developed around this period.
The evolution of the magic lantern was inextricably linked to the history of artificial light sources, as early versions using candles and oil lamps produced very dim projected images. The invention of the Argand lamp in the 1790s helped to make the images brighter, but it was the invention of limelight in the 1820s that truly revolutionized the medium, emitting about 6000 to 8000 lumens and making the images vivid enough for large audiences. This chemical light source, which involved burning a mixture of oxygen and hydrogen to create an intensely bright flame, allowed for the spectacular shows that defined the 19th century. The invention of the intensely bright electric arc lamp in the 1860s eventually eliminated the need for combustible gases or hazardous chemicals, and the incandescent electric lamp further improved safety and convenience, although not brightness. Before these advancements, the lantern was often called a lanterne de peur or lantern of fear, as the dim light and the ability to project images onto smoke or walls created an eerie atmosphere. The earliest reports suggest that the new medium was not just used for horror shows, but that many kinds of subjects were projected, including figures, paintings, portraits, faces, hunts, and even entire comedies with all their lively colors. The transition from dim candlelight to the brilliance of limelight transformed the magic lantern from a curiosity into a powerful tool for entertainment and education.
Mechanical Marvels
The magic lantern was not merely a static projector but a sophisticated engine for animation that predated the motion picture camera by nearly a century. Some suggestion of movement could be achieved by alternating between pictures of different phases of a motion, but most magic lantern animations used two glass slides projected together, one with the stationary part of the picture and the other with the part that could be set in motion by hand or by a simple mechanism. By 1709, a German optician and glass grinder named Themme made moving lantern slides, including a carriage with rotating wheels, a cupid with a spinning wheel, a shooting gun, and falling bombs. Wheels were cut from the glass plate with a diamond and rotated by a thread that was spun around small brass wheels attached to the glass wheels. Various types of mechanisms were commonly used to add movement, including slipping slides where a movable glass plate was slipped over a stationary one, lever slides operated by a handle, and pulley slides that rotated moving parts. A more complex astronomical rackwork slide showed the planets and their satellites orbiting around the sun, while fantoccini slides used jointed figures set in motion by levers, thin rods, or cams and worm wheels. These mechanical slides allowed for repetitive movements like the sails on a windmill turning around or children on a seesaw, and could be performed at different speeds to create convincing illusions of life.
The Dissolving View
The effect of a gradual transition from one image to another, known as a dissolve in modern filmmaking, became the basis of a popular type of magic lantern show in England in the 19th century. The effect was reportedly invented by phantasmagoria pioneer Paul de Philipsthal while in Ireland in 1803 or 1804, who thought of using two lanterns to make the spirit of Samuel appear out of a mist in his representation of the Witch of Endor. While working out the desired effect, he got the idea of using the technique with landscapes, presenting what was possibly a relatively early incarnation of a dissolving views show in 1812. Another possible inventor is Henry Langdon Childe, who purportedly once worked for De Philipsthal and is said to have invented the dissolving views in 1807, improving and completing the technique in 1818. The oldest known use of the term dissolving views occurs on playbills for Childe's shows at the Adelphi Theatre in London in 1837. Biunial lanterns, with two projecting optical sets in one apparatus, were produced to more easily project dissolving views, and later triple lanterns enabled additional effects, such as the effect of snow falling while a green landscape dissolves into a snowy winter version. A mechanical device could be fitted on the magic lantern, which locked up a diaphragm on the first slide slowly whilst a diaphragm on a second slide opened simultaneously, creating a seamless transition that amazed audiences.
The Horror Show
Phantasmagoria was a form of horror theater that used one or more magic lanterns to project frightening images, especially of ghosts, and it was very popular in Europe from the late 18th century to well into the 19th century. It is thought that optical devices like concave mirrors and the camera obscura have been used since antiquity to fool spectators into believing they saw real gods and spirits, but it was the magician physicist Phylidor who created what must have been the first true phantasmagoria show. He probably used mobile magic lanterns with the recently invented Argand lamp to create his successful ghost apparitions in Vienna from 1790 to 1792. As Paul Filidort, he presented his Phantasmagorie in Paris from December 1792 to July 1793, probably using that term for the first time. One of many showmen who were inspired by Phylidor, Etienne-Gaspard Robert became very famous with his own Fantasmagorie show in Paris from 1798 to 1803, later performing throughout Europe and returning to Paris for a triumphant comeback in 1814. He patented a mobile Fantascope lantern in 1798, and showmen used rear projection, mobile or portable projectors, and a variety of effects to produce convincing necromantic experiences. In 1670, Walgensten projected an image of Death at the court of King Frederick III of Denmark, which scared some courtiers, but the king dismissed their cowardice and requested to repeat the figure three times. The king died a few days later, adding a layer of grim legend to the history of the device.
The Slide Revolution
In 1848, a New York optician began advertising imported slides and locally produced magic lanterns, but by 1860, mass production began to make magic lanterns more widely available and affordable, with much of the production in the latter half of the 19th century concentrated in Germany. These smaller lanterns had smaller glass sliders, which instead of wooden frames usually had colorful strips of paper glued around their edges with the images printed directly on the glass. The first photographic lantern slides, called hyalotypes, were invented by the German-born brothers Ernst Wilhelm and Friedrich Langenheim in 1848 in Philadelphia and patented in 1850. After 1820, the manufacturing of hand colored printed slides started, often making use of decalcomania transfers, and many manufactured slides were produced on strips of glass with several pictures on them. Philip Carpenter's London company, which became Carpenter and Westley after his death, started manufacturing a sturdy but lightweight and transportable Phantasmagoria lantern with an Argand style lamp in 1821. Carpenter also developed a secret copper plate printing burning process to mass-produce glass lantern slides with printed outlines, which were then easily and quickly hand painted ready for sale. The first known set The Elements of Zoology became available in 1823, with over 200 images in 56 frames of zoological figures, classified according to the system of the Swedish scientist Carl Linnaeus. This shift from hand-painted glass to mass-produced printed slides democratized the technology, making it a staple of science lecturing and museum events.
The Silent Cinema
The magic lantern was in wide use from the 18th century until the mid-20th century when it was superseded by a compact version that could hold many 35 mm photographic slides: the slide projector. The popularity of magic lanterns waned after the introduction of movies in the 1890s, but they remained a common medium until slide projectors became widespread during the 1950s. Some enthusiasts claim that the brilliant quality of color in lantern slides is unsurpassed by successive projection media, and the magic lantern and lantern slides are still popular with collectors and can be found in many museums like the Museum of Precinema in Padua where 60 magic lanterns and more than 10000 original slides are preserved. However, of the original lanterns from the first 150 years after its invention only 28 are known to still exist as of 2009. Because the original slides are fragile, rather than display or project them, museums often digitize the slides for exhibition. A collaborative research project of several European universities called A Million Pictures started in June 2015 and lasted until May 2018, addressing the sustainable preservation of the massive, untapped heritage resource of the tens of thousands of lantern slides in the collections of libraries and museums across Europe. Genuine public lantern shows are relatively rare today, with several regular performers claiming they are the only one of their kind in their part of the world, including Pierre Albanese and glass harmonica player Thomas Bloch who have performed live Magic Lantern Phantasmagoria shows since 2008 in Europe.
