[Gr. ἐν, in, ὀρθός, upright, correct, and τρέπειν, to turn.] A toy, consisting of a card, upon the sides of which confused or incomplete figures are so drawn that when it is rapidly revolved, these representations, being combined by the eye, in consequence of the persistence of the luminous impression, form regular and perfect figures; a thaumatrope.
