The History of Stop Motion:
The Daedalum and The Zoetrope
The Daedalum, a reference to the Greek myth of Daedalus, was created a year after the Phenakistoscope in 1833 by British Mathematician William Horner, after studying its mathematical principles. The phases of movement are seen in the form of an infinite loop through the slits in between the changing images. You see one image then no image then a slightly different second image, giving the impression of movement.
The Daedalum later became the Zoetrope, which was invented by William Lincoln and Milton Bradley in 1865. The Zoetrope was almost identical to the design of the Daedalum, however the slits were placed on the level above the pictures rather than between them, which allowed easily replaceable strips of images. When evaluating the new version of the Daedalum, the Zoetrope, I discovered that this same model was then improved 3 years later by James Maxwell which used concave lenses instead of slits, resulting in the image appearing in the middle must sharper and steadier than the original Zoetrope.
