Magic Lanterns
in the 18th Century

At its most basic level, describing what is a magic lantern is a bit like describing an early sort of slide show. Light is projected through a painted glass slide (or, later in the century, through a transparent print) and onto a screen. This spectacle was portable, and could be displayed for paying spectators in public settings, or at a private home.

Jean-Baptiste le Rond d'Alembert provided a good definition of a magic lantern with a diagram showing how it works in his Encyclopédie in 1765; a 1798 Encyclopædia provides an even more thorough description of “this very remarkable machine, which is now known all over the world,” with sections on a Method of Painting the Glaſſes for the Lantern, To repreſent a Tempeſt by the Magic Lantern, The Nebulous Magic Lantern (projecting images onto “a cloud of ſmoke”), To produce the Appearance of a Phantom upon a Pedeſtal placed in the middle of a Table, and The Magic Theatre.

Many depictions of magic lantern shows are intended as satires, setting forth the illusionistic nature of the spectacle as a metaphor for current events. I’ve also gathered some newspaper advertisements featuring references to magic lanterns and descriptions magic lantern shows.

(Later on in the 19th century, the slides were capable of movement to display animation, as demonstrated in a video from the V&A.)

Lanterne Magique.

Magic Lantern, machine invented by Father Kircker, Jesuit, that has the property of making small figures painted on thin pieces of glass appear larger on a white wall, and with fully transparent colors.

For this effect, one places a strong light behind the painted glass, on which is placed the representation of the object, and in front, some distance away from the glass, one places two lenticular lenses that have the property of separating the rays that leave the object, of making them diverge, and consequently projecting on the opposite wall a representation of the image that is much larger than the object. Ordinarily, one places these two lenses in a tube, where they are mobile, so that one can move them closer together or farther apart sufficiently to render the image distinctly on the wall.

This tube is attached to the front of a square box within which is the object-holder; and so that the lantern makes an even greater effect, a spherical mirror is placed in the same box, whose light occupies the foyer; and in front of the object-holder, between it and the light, a third lenticular lens is placed. Ordinarily, one slides the object-holder by using a runner operated at M close to the third lenticular lens. N O is the object-holder, on which are painted different figures that we know how to pass successively between the tube and the box, as represented in the figure.  On the magic lantern, we can consult the physics essay of Mr. Musschenbroek section 1320 and following, and the Leçons de Physique of the Abbé Nollet, book V near the end. The theory of the magic lantern is founded on a simple proposition; if one places an object a little beyond the foyer of a lens, the image of this object will be found on the other side of the lens, and the size of the image will be the same as the object, more or less as the distance between the image and the lens is the same as that between the object and the lens. Thus, we can make magic lanterns with one lenticular lens; the multiplication of these lenses serves to augment the effect.

18th century artwork and illustrations depicting magic lanterns

Several of these illustrations depict itinerant showmen carrying a large box (probably a peep show or raree show) with a magic lantern mounted on top. Many of them also carry a barrel organ or hand organ to accompany the show; this is also described in a newspaper advertisement (a couple who left behind “a Hand Organ and Magick Lanthorn” at a dwelling-house, The Gloucester Journal, February 23, 1778). See also The Hurdy-Gurdy and the Magic Lantern.

Advertisements for magic lanterns and shows

Several of the wondrous spectacles advertised in 18th century puppet shows may have also been performed with magic lanterns. For example, the entertainments promised by “Signor Gulielmo Pittachio” (The Northern Star, September 14, 1795) include both a magic lantern and a puppet show.
