Phen`a*kis"to*scope, n. Etym: [Gr. -scope.]
Definition: A revolving disk on which figures drawn in different relative
attitudes are seen successively, so as to produce the appearance of
an object in actual motion, as an animal leaping, etc., in
consequence of the persistence of the successive visual impressions
of the retina. It is often arranged so that the figures may be
projected upon a screen.
