The magic lantern, also known by its Latin name lanterna magica, is an early type of image projector employing pictures painted, printed or produced photographically on transparent plates (usually made of glass), one or more lenses, and a light source. It was mostly developed in the 17th century and commonly used for entertainment purposes. It was increasingly applied to educational purposes during the 19th century. Since the late 19th century smaller versions were also mass-produced as a toy for children. The magic lantern was in wide use from the 18th century until the mid-20th century, when it was superseded by a compact version that could hold many 35 mm photographic slides, the slide projector.Collection
