Part of speech: noun

Definitions

1. A historical optical device that creates an illusion of motion by displaying a sequence of drawings or photographs through slits on a spinning disc; a precursor to modern animation tools; used for entertainment and visual demonstration of movement
2. An early animation apparatus designed to produce moving images by spinning a disc with sequential pictures viewed through narrow openings; an important step in the development of cinematic technology and motion perception
3. A mechanical invention consisting of a rotating circular card with pictures in progressive phases and slits to view them in rapid succession, generating the effect of continuous motion; a foundational instrument in the history of animation and visual arts

Etymology: The name rests on an ancient Greek word, "phenakistes," meaning "cheat" or "impostor." That makes it a fitting label for a device that tricks the eye into seeing motion where none exists. The ending "-scope" comes from Greek roots meaning to look or view, the same element found in "microscope" and "telescope." Together the parts suggest a deceptive viewer. The name reached English through French, where it was coined as "phénakistiscope," so the English form is a borrowing of that French formation rather than a direct import from Greek.

Synonyms: optical toy, animation disc
