In Greek mythology, Andromeda (; or ) is the daughter of Cepheus, the king of Aethiopia, and his wife, Cassiopeia. When Cassiopeia boasts that she (or her daughter) is more beautiful than the Nereids, Poseidon sends the sea monster Cetus to ravage the coast of Aethiopia as divine punishment. Andromeda is chained to a rock as a sacrifice to sate the monster, but is saved from death by Perseus, who marries her and takes her to Greece to reign as his queen.
As a subject, Andromeda has been popular in art since classical times; rescued by a Greek hero, Andromeda's narration is considered the forerunner to the "princess and dragon" motif. From the Renaissance, interest revived in the original story, typically as derived from Ovid's Metamorphoses. The story has appeared many times in such diverse media as plays, poetry, novels, operas, classical and popular music, film, and paintings. A significant part of the northern sky contains several constellations named after the story's figures; in particular, the constellation Andromeda is named after her.
The Andromeda tradition, from classical times onwards, has incorporated elements of other stories, including Saint George and the Dragon, introducing a horse for the hero, and the tale of Pegasus, Bellerophon's winged horse. Ludovico Ariosto's epic poem , which tells a similar story, has introduced further confusion. The tradition has been criticized for depicting the princess of Aethiopia as white; few artists have chosen to portray her as dark-skinned, despite Ovid's account of her. Others have noted that Perseus's liberation of Andromeda was a popular choice of subject among male artists, reinforcing a narrative of male superiority with its powerful male hero and its submissive female in bondage.
Etymology
The name Andromeda is from the Greek , perhaps meaning 'mindful of her husband'. The name is from the noun meaning 'man', and a verb, whether , , or , all related to , the likely origin of the name of Medea, the sorceress.
Classical mythology
Central story
In Greek mythology, Andromeda is the daughter of Cepheus and Cassiopeia, king and queen of ancient Aethiopia. Her mother Cassiopeia foolishly boasts that she is more beautiful than the Nereids, a display of hubris by a human that is unacceptable to the gods. To punish the queen for her arrogance, Poseidon floods the Ethiopian coast and sends a sea monster named Cetus to ravage the kingdom's inhabitants. In desperation, King Cepheus consults the oracle of Ammon, who announces that no respite can be found until the king sacrifices his daughter, Andromeda, to the monster. She is thus stripped naked and chained to a rock in Jaffa by the sea to await her death. Perseus is just then flying near the coast of Ethiopia on his winged sandals or on Pegasus the winged horse, having slain the Gorgon Medusa and carrying her severed head, which instantly turns to stone any who look at it. Upon seeing Andromeda bound to the rock, Perseus falls in love with her, and he secures Cepheus' promise of her hand in marriage if he can save her. Perseus kills the monster with the magical sword he had used against Medusa, saving Andromeda. Preparations are then made for their marriage, in spite of her having been previously promised to her uncle, Phineus. At the wedding, a quarrel between the rivals ends when Perseus shows Medusa's head to Phineus and his allies, turning them to stone.
Andromeda follows her husband to his native island of Serifos, where he rescues his mother, Danaë. They next go to Argos, where Perseus is the rightful heir to the throne. However, after accidentally killing his grandfather Acrisius, the king of Argos, Perseus chooses to become king of neighboring Tiryns instead. The mythographer Apollodorus states that Perseus and Andromeda have six sons: Perses, Alcaeus, Heleus, Mestor, Sthenelus, Electryon, and a daughter, Gorgophone. Their descendants rule Mycenae from Electryon down to Eurystheus, after whom Atreus attains the kingdom. The Greek hero Heracles is also a descendant, as his mother Alcmene is the daughter of Electryon.
According to the Catasterismi, Andromeda is placed in the sky by Athena as the constellation Andromeda, in a pose with her limbs outstretched, similar to when she was chained to the rock, in commemoration of Perseus' bravery in fighting the sea monster.
