Fantoscope disc, 1833.

Made by Ackermann and Co in 1833, the disc shows a dancer turning on the spot. The Fantascope is another name for the Phenakistoscope, which was invented by the Belgian physicist Joseph Plateau (1801-1883) in 1832. By spinning the disc, picture side towards a mirror, and looking through the slits which act as shutters, a brief reflection of each succesive picture can be seen, making the subjects in the pictures appear to move.
