The use of image sequences to depict motion dates back nearly two centuries. One of the earlier approaches to motion picture “display” was invented in 1834 by the mathematician William George Horner. Originally called the Daedaleum (after Daedalus, who was supposed to have made figures of men that seemed to move), it was later called the Zoetrope (literally “life turning”) or the Wheel of Life. The Daedaleum works by presenting a series of images, one at a time, through slits in a circular drum as the drum is rotated.
