Detail of galloping horses on disc. Derived from the chronophotographs made by the photographer Eadweard Muybridge (1830-1904), this disc was one of several made for the Zoopraxiscope projector he designed in 1879. The Zoopraxiscope was devised to project a cycle of natural human and animal movements from a series of still photographs upon a screen. Based on the principle of the Phenakistoscope, the Zoopraxiscope had a counter-rotating shutter which briefly flashed each image onto the screen as the disc rotated. Muybridge gave highly succesful lectures with this apparatus for many years. He was the first photographer to carry out the analysis of movement by sequence photography, an important stage in the invention of cinematography.
