At an early date the conflict arose between those who wished to use the magic shadows to entertain and instruct and those who wished to use them for purposes of deception.
The Egyptian priests have first claim on the title of light and shadow showmen. Some of the fragments of hieroglyphics indicate that they used optical devices to deceive. It is likely that a simple mirror was used to throw images into space. But that would have amazed the people and would have been taken as a sure sign of miraculous power.
The oldest media of light and shadow entertainment and deception was developed by another great and scholarly group, the early Chinese scientists. These were the Chinese Shadow Plays, the origin of which is lost in antiquity, dating back perhaps to 5000 B.C. Silhouette figures shown on a background of smoke and animated as in a puppet show entertained a public thousands of years ago in the Far East. The Chinese Shadow Plays appear to have a close relation to the old-time fireside tricks of twisting the fingers so as to form what appeared to be the shadow of a donkey’s head or a representation of a rabbit or of some other animal. Despite the troubled history of China, these Shadow Plays were never lost and they are still presented in remote parts of China and in Java.
Dates of the Chinese contributions to the story of the origin of the cinema and related sciences are uncertain. The Chinese empire was founded around 2800 B.C. and within 500 years of that time the heavens had been charted by the Chinese. A hundred years after an hereditary monarchy was established in China, about 2200 B.C., the ruling powers executed two astronomers for failing to observe properly an eclipse of the sun.
After the Chinese Shadow Plays, mention should be made of another Oriental light and shadow invention. This one was developed by the Japanese. The devices are known as Japanese Mirrors. These are famed in legend and history as being endowed with great magical powers. They, as in the inventions of the Egyptians, used an optical illusion to entertain and also to trick.
The method of the Japanese Mirrors was simple: They were of polished bronze with a design embossed on the surface. When held to the sun, the reflected light would fall on a wall or other smooth surface, and the spectators would see the design, appearing as if through the power of the devil or some propitious deity. If the operator did not allow his mirror to be closely examined by the audience he could certainly be credited with magical powers—the power to bring animals and men, and any kind of design to life. Not a devil or a god; but in reality only an early showman! And done with mirrors!
The so-called English Mirrors, of a much later date, worked on a similar principle, but were even more ingenious. They had greater “magical” power. The English Mirrors resembled the Japanese Mirrors, yet on close examination no embossing would be discovered on the surface. Even today one might have a difficult time discovering the secret.
The picture to be projected was very carefully and lightly etched with acid upon the brass surface of the English Mirrors. The mirror was then polished until the etched pattern could not be detected by eye or touch. But the imperceptible roughness outlining the pattern remained on the mirror and was sufficient to record and reflect the outline of the design in what seemed a magical fashion.
After a vague start in Babylonia, Egypt and the Far East, the study of light and shadow, like many another art and science, began in a thorough way in Greece.
Aristotle, great Greek philosopher, born about 384 B.C., made the first important contribution to the history of the light and shadow art-science which can be assigned to an identifiable individual.
