Magic lanterns, also known as optical lanterns, provided one of the most popular forms of entertainment during their heyday in the 18th and 19th centuries, establishing many of the first 2-D special effects. Using an artificial light source and a combination of lenses, these devices enlarged small transparency images or miniature models and projected them onto a wall or screen. While most magic lanterns were designed as simple wooden boxes fitted with a handful of precision brass parts, a few were ornately decorated with exotic painted scenes or engraved metal casings.
