  • n. An optical toy similar to the phenakistoscope. See Phenakistoscope.

from The Century Dictionary and Cyclopedia

  • n. An instrument used in the study of the periodic motion of a body, as one in rapid revolution or vibration, by illuminating it at frequent intervals (for example, by electric sparks or by a beam of light made intermittent by passing through a moving perforated plate), or again by viewing it through the openings of a revolving disk: also used as a toy. The phenakistoscope and zoëtrope represent one form of stroboscope.
