The Cassiopeia constellation is a constant presence in the northern sky after the queen of Aethiopia. Cassiopeia was the wife of Cepheus, King of Aethiopia and mother of Princess Andromeda. She was exiled to the sky as punishment for boasting that Andromeda was more beautiful than the Nereids and consequently forced to wheel around the North Celestial Pole on her throne clinging for dear life.
