About the praxinoscope we can say that it is the successor of the zoetrope. It is a more elaborate ingenuity whose inventor was the French Charles Emile Raynaud, and which consisted of a rotating drum with a mirror ring placed in the center, and a strip full of drawings that were located on the inner wall of the drum. By turning the drum by hand, the drawings begin to come to life. It was used in the optical theater, giving a great spectacle from the projection of different cartoons placed in a flexible band with perforations that managed to present up to 15 images per second. The images that were projected inside the praxinoscope had to be drawn on the film by hand and their projections were adequately synchronized with music and some different sound effects.
The praxinoscope is the instrument that followed after the zoetrope was discontinued. It is an invention that had a rotating drum with mirrors placed in the center and a strip of drawings on the inside of the drum that as it spins, gave life to the different drawings it had.
The praxinoscope was a device created for theatre and was invented by Emile Reynaud in 1879. This apparatus was very similar to the zoetrope and even used almost the same system to give animation to the images, it was in itself a kind of zoetrope, with the difference that replaced the drum slots with mirrors inside it. The biggest difference that existed with the zoetrope is that in the praxinoscope, the moving images are seen through a crystal that reflects a latent still image that is the stage.
During the 30’s of the 19th century different types of optical toys were developed whose function was to offer movement illusion through different images sequences that passed by different types of shutters. At that time, Reynaud was responsible for making praxinoscopes that were then traded and sold as toys.
The invention received an honorable mention at the Universal Exhibition in Paris in 1878. Years after having invented the praxinoscope, Charles-Émile Reynaud made several improvements to his invention, and in 1888 he baptized it with the name of Théâtre Optique (Optical Theatre). This device was widely used in Europe and the United States as a form of entertainment. In 1888 a step forward was made, and the optical theatre was invented, in which the images of the praxinoscope were projected in public on a large screen.
The praxinoscope is a toy which function is to create a series of images that constantly change and consists of drawings that follow an order and sequence which are placed on a rotating drum, specifically on its internal wall, which at the same time are reflected by another drum that has different sides provided with a set of mirrors in equal quantity to the number of drawings being presented. These drawings rotate in opposite form so that, they can be seen through special lens designed for this purpose.
As a result of this process, people can observe a clear and clean sequence in which images can merge in a correct way achieving an animation effect. The praxinoscope moves through repetitive movements forming an action marked by activation and deactivation of each object’s mechanism. The gaze and the correct manipulation of the apparatus are two crucial aspects for its good functioning since the spectator must keep his sight fixed.
