    • n praxinoscope An instrument allied to the phenakistoscope and zoetrope, and giving like effects. Pictures representing a cycle of positions of a moving object, as a running horse or a dancer, are arranged in due order on the inside surfaces of a polygonal box in the center of which is also placed a polygonal prism having one side facing each picture in the cycle. On each face of the prism is affixed a flat mirror. The box with its contained pictures and mirrors is rotated horizontally. The eye, fixed upon the central arrangement of mirrors, then sees the object apparently performing its natural movements.
