In Greek mythology, Andromeda (ancient Greek Ἀνδρομέδα / Andromeda, "that leads men"), is the daughter of Cepheus and Cassiopeia, king and queen of Ethiopia.
Cassiopeia, having proclaimed that his daughter (or other versions of itself) was equal to the beauty of Nereides, had attracted the wrath of Poseidon, which provoked a revenge flooding and sent a sea monster ( Cetus the whale), which began to destroy men and cattle.
The oracle of Ammon showed no respite would be possible as the king does not deliver his daughter to a monster. It was therefore committed to a bare rock on the coast. Perseus, which was returning from his victory on the Gorgon Medusa, found Andromeda, slew the monster and freed the girl. Ovid says that algae solidified by the venom of snakes of Medusa established the property rigidifiante coral sea, when it comes into contact with air.
Perseus married Andromeda although it was promised to Phineas, the brother of Cepheus. During the marriage, a quarrel took place between the two contenders Phineas and was in turn changed into stone by the head of the Gorgon.
Andromeda followed her husband to Tiryns in Argolis and became the ancestor of the family Perseid through his son Persians. Perseus and Andromeda had six son: Persians, Alcea, Heleos, Mestor, Sthenelos and Electryon, and a daughter: Gorgophoné. Their descendants ruled the Mycenie of Electryon up Eurysthea, Atreus who received the kingdom, and the great hero Hercules is part of that descent.
After his death, Andromeda was placed by Athena amongst the constellations, near Perseus and Cassiopeia.
Sophocles and Euripides, and in modern times, Corneille, wrote the story of his tragedy and his misfortune is the subject of numerous works of ancient art.(Sony)
