The Zoopraxiscope

The Zoopraxiscope (earlier known as the Zoogyroscope) was essentially a projecting version of the old Phenakisticsope or ‘spinning picture disk’.   The device projected sequences of images from glass discs and was devised in order to prove the authenticity of Muybridge's galloping horse pictures.   The earlier Zoogyroscope took the 16 inch discs while the latter Zoopraxiscope took the 12 inch discs.

Biunial Lantern

Muybridge's Biunial Lantern has several curious features.  It appears to have had its footprint reduced for reasons unknown.  It also has a facility for extending the two lenses and thereby allowing for a mechanism to be placed between the light source and the lenses.  It is possible that this adapted lantern may have doubled-up as a second zoopraxiscope.
