Andromeda

Andromeda, daughter of Cepheus, King of AEthiopia, and of Cassiopeia. The latter disputed the palm of beauty with the Nereids, and thus provoked Poseidon, who sent a sea-monster to devastate the realms of Cepheus. Andromeda was chained to a rock as a propitiatory victim, but Perseus slew the brute, rescued the princess, and was rewarded with her hand. Andromeda after death was, like her mother, enrolled amongst the constellations.
