In Greek mythology, Andromeda ("ruler of men") was the daughter of Cepheus and Cassiopeia, king
and queen of Aethiopia.
Paul Gustave Doré painted Andromeda exposed to the sea-monster.Cassiopeia, having boasted herself equal in beauty to
the Nereids, drew down the vengeance of Poseidon, who sent an inundation on the land and a sea-monster, which destroyed man
and beast. The oracle of Ammon announced that no relief would be found until the king exposed his daughter Andromeda to the
monster, so she was fastened to a rock on the shore.
Perseus, returning from having slain the Gorgon, found Andromeda, slew the monster, set her free, and married her in spite
of Phineus, to whom she had before been promised. At the wedding a quarrel took place between the rivals, and Phineus was
turned to stone by the sight of the Gorgon's head (Ovid, Metamorphoses v. 1).
Andromeda followed her husband to Tiryns in Argos, and became the ancestress of the family of the Perseidae through Perseus'
and Andromeda's son, Perses. Perseus and Andromeda had six sons (Perseides): Perses, Alcaeus, Heleus, Mestor, Sthenelus, and
Electryon, and one daughter, Gorgophone. Their descendants ruled Mycenae from Electryon down to Eurystheus, after whom Atreus
got the kingdom, and include the great hero Heracles. According to this mythology, Perses is the ancestor of the Persians.
After her death she was placed by Athena amongst the constellations in the northern sky, near Perseus and Cassiopeia. Sophocles
and Euripides (and in more modern times Corneille) made the story the subject of tragedies. The tale is represented in numerous
ancient works of art.
Andromeda is represented in the northern sky by the constellation Andromeda which contains the Andromeda Galaxy.
This event was depicted in a modified version in the 1981 movie Clash of the Titans.
