Replica. Eadweard Muybridge (1830-1904) designed the Zoopraxiscope in 1879 to project upon a screen a cycle of natural human and animal movements from a series of still photographs. 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 was the first photographer to carry out the analysis of movement by sequence photography, an important stage in the invention of cinematography.
