The birth of cinema began with a concept called persistence of vision, which British physician Peter Mark Roget introduced in 1824. Based on this concept, individual still pictures set into motion create the illusion of movement. The early 17th to late 18th centuries saw the inventions of technologies that included optical toys and mechanical inventions related to motion and vision. Athanasius Kircher invented the magic lantern in the 17th century. The magic lantern was a device with a lens that can project images from transparencies onto a screen with a simple light source like a candle. In 1824 Peter Mark Roget invented the Thaumatrope, the earliest version of an optical illusion toy that applied the concept of persistence of vision. English scientist Michael Faraday discovered the law of electromagnetic induction in 1831. Faraday’s principle made contributions to the development of film equipment. A year later, Belgian inventor Joseph Plateau invented the Fantascope, a device that stimulated motion. A series of separate pictures that depicted stages of an activity like dancing were arranged around the edges of a slotted disk. This disk was placed before a mirror and rotated as the spectator looked at the moving picture through the slots. Another inventor, William George Horner invented the stroboscopic device adaptation, the Daedalum in 1834. This device was a hollow, rotating cylinder with a crank and strip of sequential photographs, drawings, paintings or illustrations on the interior surface. It also had narrow slits where the spectator looked through to see the drawings in motion. This was like how you watch movies online free streaming except that you look through a device and see the drawings spring to life. Another device, the Kinematoscope, was patented by Coleman Sellers in 1861 to view still pictures. This device was a rotating paddle machine where you could see a series of stereoscopic still pictures on glass plates that were sequentially mounted in a cabinet-box. In 1870, Henry Renno Heyl invented the Phasmotrope that showed a rapid succession of still photographs of dancers, giving an illusion of motion. These photographs are just like the scenes that change when you watch movies online free streaming. If it were not for all these inventions, you would not be able to watch movies online free streaming. All these inventions apply the concept of the illusion of motion which led to the creation of films.
