Andromeda

Andromeda was a woman from Greek mythology who, as divine punishment for her mother's bragging, was chained to a rock as a sacrifice to a sea monster. She was saved from death by Perseus, her future husband. Her name is the Latinized form of the Greek Ανδρομέδη (Andromēde). The etymology of the name is "to think of a man," from ανδρός (andros) "man" combined with μήδομαι (mēdomai) "to think, to be mindful of."

Her mother Cassiopeia bragged that she was more beautiful than the Nereids, the nymph-daughters of the sea god Nereus and often seen accompanying Poseidon. To punish the Queen for her arrogance, Poseidon, brother to Zeus and God of the Sea, sent a sea monster called Cetus to ravage the coast of Ethiopia and the kingdom of the vain Queen. The desperate King consulted the Ammon, the Oracle of Zeus, who announced that no respite would be found until the king sacrificed his virgin daughter Andromeda to the monster. She was chained naked to a rock on the coast of Jaffa. The rock is allegedly still visible today.
Perseus, returning from having slain the Gorgon Medusa, found Andromeda and slew the monster Cetus. He set her free, and married her in spite of Andromeda having been previously promised to Phineus. 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).
