The magic lantern is the predecessor of the modern day projector. It consisted of a translucent oil painting and a simple lamp. When put together in a darkened room, the image would appear larger on a flat surface.Athanasius Kircher spoke about this originating from China in the 16th century.[citation needed] Some slides for the lanterns contained parts that could be mechanically actuated to present limited movement on the screen.
