Andromeda, << an DROM uh duh, >> in Greek mythology, was the daughter of Cassiopeia and Cepheus, rulers of Ethiopia. Cassiopeia dared to compare her own beauty to that of the Nereids (sea nymphs) who attended Poseidon. In anger, Poseidon sent a sea monster to attack Ethiopia. An oracle said Andromeda should be sacrificed to the serpent to save the land. Perseus saw Andromeda chained to a rock, fell in love with her, and killed the monster. He then married Andromeda. Among their descendants was Hercules. After her death, Andromeda became a constellation.
