Antique magic lantern.. It is made of metal with two magnifying lenses.. One is outside and one us inside.. Both lenses are in great condition with no breaks.. The original kerosene burner is still intact.. Two of its feet are missing.. The rest of the majic lantern is in great condition.. There is an original wooden box of 13 slides to go with it but no room for pictures.. Email me for pictures of the glass slides.. Most are in great condition.. I took pictures of the laying on an upturned light so the shadows show up badly.. It is very hard to get pictures of these but I do have them.. Varied subjects like boats, trains, people with scenery and children..I have a stack of slides I will be selling separately.. If anyone wants them all please let me know and I will make you a great deal on them and include them with the shipping on the magic lantern.. Here is the information I found on them.. A lot of the slides do look hand painted..
A page of Willem 's Gravesande's 1720 book Physices Elementa Mathematica with Van Musschenbroek's magic lantern projecting a minotaur. The depicted magic lantern is the oldest known to be preserved and is in the collection of Museum Boerhaave, Leiden The magic lantern used a concave mirror in back of a light source to direct as much of the light as possible through a small rectangular sheet of glass—a "lantern slide"—on which was the image to be projected, and onward into a lens at the front of the apparatus. The lens was adjusted to optimally focus the plane of the slide at the distance of the projection screen, which could be simply a white wall, and it therefore formed an enlarged image of the slide on the screen. Some lanterns, including those of Christiaan Huygens and Jan van Musschenbroek, used 3 lenses.
Originally the pictures were hand painted on glass slides. Initially figures were rendered with black paint but soon transparent colors were also used. Sometimes the painting was done on oiled paper. Usually black paint was used as a background to block superfluous light, so the figures could be projected without distracting borders or frames. Many slides were finished with a layer of transparent lacquer, but in a later period cover glasses were also used to protect the painted layer. Most hand-made slides were mounted in wood frames with a round or square opening for the picture.
After 1820 the manufacturing of hand colored printed slides started, often making use of decalcomania transfers. Many manufactured slides were produced on strips of glass with several pictures on them and rimmed with a strip of glued paper.
Not long after the introduction of photography in 1839 photographic images could be projected with magic lanterns.
Apart from sunlight, the only light sources available at the time of invention in the 17th century were candles and oil lamps, which were very inefficient and produced very dim projected images. The invention of the Argand lamp in the 1790s helped to make the images brighter. The invention of limelight in the 1820s made them very much brighter. The invention of the intensely bright electric arc lamp in the 1860s eliminated the need for combustible gases or hazardous chemicals, and eventually the incandescent electric lamp further improved safety and convenience, although not brightness.
