In Ray Bradbury's short story, "The Flying Machine," set in fifth century China, the Emperor is told by a servant of the miracle he has seen: a man flying using a machine made of paper and bamboo. The Emperor demands to see this man.
The inventor explains to the Emperor that he made the machine for the sake of innovation. The Emperor shows the other man his own invention, a miniature world placed within a box. It is a wind-up machine with trees and tiny birds. Even though it is a beautiful thing, the Emperor fears that such things bring about change, and will, ultimately destroy the Emperor's desire for peace in the world as he knows it.
This is an example of foreshadowing. If the Emperor will not share his machine with the world, he certainly will not agree that the inventor's machine can exist or even be spoken about to the world at large.
So the Emperor orders that the inventor must be killed, his machine destroyed, and those who have witnessed the "miracle" be "silenced."
