Praxinoscope. Historical engraving of a young girl watching a man using a praxinoscope. Invented by M. Reynaud of Paris, France, the praxinoscope was a nineteenth century novelty item that was a precursor to modern cinematography. As with cinematography, the praxinoscope depended on persistence of vision. When viewing the revolving drum though a slit (upper right), the pictures appeared to move.
