Cleopatra ( Kleopatra; "Glory of the father") in Greek mythology was the name of two Danaides of altogether 50 daughters of Danaus sired with different women. Each of the two Cleopatras married â like all their sisters â one of the 50 sons of Danausâ twin brother Aegyptus. One Cleopatra, whose mother was a hamadryad (Atlantia or Phoebe), married Agenor, and the other Cleopatra, the daughter of the naiad Polyxo, married Hermus. Like all Danaides â except Hypermnestra â both Cleopatras killed their husbands on their wedding night.
