Cepheus the King
This constellation is believed to date as far back as 23 centuries and that is was recognized by the Chaldeans. Cepheus, King of Ethiopia, and husband of the vain Caaaiopeia sits on his throne as he circles the pole. It has also been said that Cepheus was one of the Argonauts and that he accompanied Jason on the quest for the golden fleece. For his honor and bravery, he was placed in the sky. The Chinese regarded these stars highly and associated them with royalty by calling them the Inner Throne of the Five Emperors. The Arabs saw in these stars a shepherd, his dog and a flock of sheep.
