Part of Lantern Slide Collection
This sub-series contains 31 glass lantern slides with various forms of mechanisms, including the rack and pinion, double pulley, single lever (or Fantoccinni) and glass slipping slides (with a single or double slipper).
A variety of techniques were developed in an attempt to create the illusion of movement in lantern slides. For instance, in the slipping slide, a glass overlay with selective blackout was used to conceal and reveal portions of the drawing. in a rack and pinion slide, glass discs were rotated using a handle. This mechanism was often used for chromatropes, or to demonstrate astrological concepts.
