A raree show, peep show or peep box is an exhibition of pictures or objects (or a combination of both), viewed through a small hole or magnifying glass. In 17th and 18th century Europe, it was a popular form of entertainment provided by wandering showmen. History Peep shows, also known as peep box or raree show ("rarity show") can be traced back to the early modern period (15th century in Europe) and are known in various cultures. Around 1437 Italian humanist author, artist, architect, poet, priest, linguist, philosopher and cryptographer Leon Battista Alberti is thought to have created the earliest impressive peep show boxes with painted pictures to be viewed through a small hole. He had two kinds: night scenes with the moon and stars, and day scenes. It is thought these pictures may have been transparent and lit from behind, possibly changing from day to night by changing the lighting. It has also been suggested that it may have been a predecessor of the magic lantern that could project images.In the 17th and 18th century peep shows were exhibited on streets and fairs across Europe by itinerant showmen, competing with other entertainment like dancing bears, jugglers, conjurers, et cetera. Their wooden cabinets could have several viewing holes and contain sets of pictures to be set into a viewing position by pulling a corresponding string. The show was accompanied by spoken recitation that explained or dramatized what was happening inside. The boxes were often decorated inside to resemble theatrical scenes. Peep shows were most popular in the 17th century in Holland. Some artists from the 17th-century Dutch Golden Age painting, like Pieter Janssens Elinga and Samuel Dirksz van Hoogstraten created a type of peep shows with an illusion of depth perception by manipulating the perspective of the view seen inside, usually the interior of a room. From around 1700 many of these "perspective boxes" or "optica" had a bi-convex lens with a large diameter and small dioptre for an exaggerated perspective, giving a stronger illusion of depth. Most pictures showed architectural and topographical subjects with linear perspectives. From around 1745 similar perspective view prints became very popular for the zograscope, which used the same principle with the lens on a stand rather than in a box. Peep shows were further developed with translucent painting techniques, perforations and cut-out shapes that provided special effects when lit from behind by candles. Changing
