It was well known that there were wandering stars, they appeared in different nightly positions against their neighbors and they became known as planets. It took centuries, in fact, it took millennia, for man to 4 the true nature of these wandering stars and to evolve a model of the world to accommodate them and to 5 their positions in the sky.
