Her mother Cassiopeia boasted of her beauty, and said that she surpassed the
Nereids. The latter prevailed on Poseidon to visit the country by an
inundation, and a sea-monster was sent into the land. The oracle of Amnion
promised that the people should be delivered from these calamities, if
Andromeda was given up to the monster; and her father, Cepheus, being
obliged to yield to the wishes of his people, chained Andromeda to a rock.
Here she was found and saved by Perseus, who slew the monster and obtained
her as his wife.
Andromeda had previously been promised to Phineus and this gave rise to the
famous fight of Phineus and Perseus at the wedding, in which the former and
all his associates were slain. Andromeda thus became the wife of Perseus,
and bore him many children. Athena placed her among the stars, in the form
of a maiden with her arms stretched out and chained to a rock, to
commemorate her delivery by Perseus.
The scene where Andromeda was fastened to the rock is placed by some of the
ancients in the neighbourhood of lope in Phoenicia, while others assign to
it a place of the same name in Ethiopia.
