Perseus in Myth
Perseus Part Three – Savior of Andromeda
Andromeda was the daughter of Cepheus, Ethiopian King and Queen Cassiopeia.
Cassiopeia had the bad sense to boast she and her daughter were more beautiful than the Nereids (sea nymphs). They complained to their protector Poseidon, who sent a flood followed by Cetus, a sea monster, to destroy their city.
Cepheus consults an oracle and learns he must sacrifice his daughter.
Perseus flies by and views the beautiful Andromeda chained naked to a rock. He makes a deal with her parents to save her from the beast – her hand in marriage.
Perseus slays Cetus and prepares to get married. Cepheus & Cassiopeia renege on the arrangement and try to have Perseus killed. Perseus wins the ensuing battle using an ancient weapon of mass destruction, Medusa’s head.
 Accounts differ about who placed their constellations in the sky. Some indicate Poseidon placed the dishonored Cassiopeia and Cepheus in the heavens as a punishment for their conniving ways with both circling the pole star while vain Cassiopeia combs her hair for eternity. He also placed Cetus, the sea monster in the heavens as a reward for the creature’s service to him. Other accounts indicate Athena placed all of them in the sky as constellations to serve as lessons, good and bad, for earthbound mortals in their common tale.
Cassiopeia had the brother of Cepheus, Phineus attempt to murder Perseus at his wedding feast.
