The Phenakistiscope used a rotating disc, the Zoetrope, Daedatelum, and Praxinoscope rotating drums; all displayed sequential images that were viewed through slots.
A zoetrope is a device that produces an illusion of action from a rapid succession of static pictures. It consists of a cylinder with slits cut vertically in the sides. Beneath the slits, on the inner surface of the cylinder, is a band which has individual images from a set of sequenced drawings or photographs. As the cylinder spins, the user looks through the slits at the pictures on the opposite side of the cylinder’s interior. The scanning of the slits keeps the pictures from simply blurring together, so that the user sees a rapid succession of images producing the illusion of motion. It was invented in 1834 by George Horner, who called it a “daedalum” or “daedatelum”. Horner’s invention was based on a similar device, the phenakistoscope, invented in 1832 by Joseph Plateau. William F. Lincoln promoted Horner’s device in America as a “zoetrope”.
