Until 1880 attributed to Chardin. The magic lantern or 'Laterna Magica' is an early type of image projector invented in the late 16th century, where translucent painted slides were lit up and magnified by a concave mirror reflecting the light of a candle or lamp. This popular form of entertainment was often featured in travelling fairs and used to create supernatural illusions such as images of the devil, phantoms, or ghosts. It is effectively one of the direct ancestors of cinematographic projectors (and of horror films).
