8. In Greek mythology, Cepheus and Cassiopeia were the King and Queen of mythical Ethiopia. Cassiopeia was very vain and bragged that she was more beautiful than the Nereid sea nymphs. The Nereids asked the gods and Poseidon to punish her, so they caused famine and pestilence. When the people could not bear it any longer they asked how they could be spared from this misery. The Nereids said they must sacrifice the beloved and beautiful Princess Andromeda to the sea monster Cetus by chaining her to a rock by the sea. Cepheus and Cassiopeia were heartbroken, but now had no choice. As Cetus rose from the sea, about to devour Andromeda, Perseus was on his way home from killing the Medusa, and riding on Pegasus, the Winged Horse. Perseus saw the beautiful Andromeda and fought the monster to save her. He was not doing very well, when he remembered the Medusa head (Algol). He took it from his bag (under Mirfak) and stretched it out in the face of Cetus, who turned to a pillar of stone. Perseus was a hero, and married Andromeda. All are remembered as constellations in our sky, but Cassiopeia and Cepheus were punished by the gods by appearing upside down for half of every year.
