Merope (Ancient Greek: Μερόπη) was a Queen of Messenia in Greek mythology, daughter of King Cypselus of Arcadia and wife of Cresphontes, the Heraclid king of Messenia. After the murder of her husband and her two older children by Polyphontes (another Heraclid), Merope was forced to marry the murderer, but she managed to save her youngest son Aepytus, whom she sent secretly to Aetolia. Several years later, when Aepytus grew up, he killed Polyphontes with the collaboration of Merope, and he took revenge for the murder of his relatives and the insult to his mother.
