In Greek mythology, Andromeda is the daughter of the Aethiopian king Cepheus and his wife Cassiopeia. When Cassiopeia's hubrisleads her to boast that Andromeda is more beautiful than the Nereids, Poseidon sends a sea monster, Cetus, to ravage Aethiopia as divine punishment. Andromeda is stripped and chained naked to a rock as a sacrifice to sate the monster, but is saved from death byPerseus.
Her name is the Latinized form of the Greek Ἀνδρομέδα (Androméda) or Ἀνδρομέδη (Andromédē): "ruler of men", from ἀνήρ, ἀνδρός(anēr, andrós) "man", and medon, "ruler".
As a subject, Andromeda has been popular in art since classical times; it is one of several Greek myths of a Greek hero's rescue of the intended victim of an archaic hieros gamos (sacred marriage), giving rise to the "princess and dragon" motif. From the Renaissance, interest revived in the original story, typically as derived from Ovid's account.
