The starry sky is the heritage of all humanity.
Since the Man is Man, he did not cease looking at the starry sky, he transcribed there his own representation and the knowledge which he had of it. Today even, we share the same sky, which knew how to cross centuries without changing. If the Man of today can pass on(transmit) such to us of knowledge on the starry sky as current science studies him, it is a bit thanks to all these representations of past. They allow to the astronomers of today to explore other tracks(runways) of investigation than those of the past which as for them, do not bring scientific answer.
