A History of Animation
The Zoetrope was originally named the 'Daedalum' [pronounced 'day-da-lum'] by its inventor, William Horner, and was based on Plateau's Phenakistoscope.
A Zoetrope is shaped like a drum, with an open top. Underneath it is supported in middle by a stand. There are a series of hand-drawn pictures on the inside. All the pictures are drawn slightly different to advance the movement, as flick books do.
The drum has slits on the outside and if the viewer looks through these while the drum is spinning, the pictures appear to be connected together and moving like a short animated film.
