The New Student's Reference Work/Andromeda
Andromeda (an-drom' e-dä), in Greek mythology the daughter of Cassiopeia and Cepheus, king of Ethiopia. Boasting that she was more beautiful than Juno, the latter's brother, Neptune, sent a sea monster to threaten her life and ravage the country. From this peril and being chained to a rock, Andromeda was rescued by Perseus, and after death was transformed into a constellation. The constellation, with its satellites, is represented by a woman in chains.
