Aerope

In Greek mythology, Aerope (Ancient Greek: Ἀερόπη) was a Cretan princess as the daughter of Catreus, king of Crete. She was the sister to Clymene, Apemosyne and Althaemenes. Aerope's father Catreus gave her to Nauplius, to be drowned, or sold abroad, but Nauplius spared her, and she became the wife of Atreus, or Pleisthenes, (or both?) and by most accounts the mother of Agamemnon and Menelaus. While the wife of Atreus, she became the lover of his brother Thyestes, and gave Thyestes the golden lamb, by which he became the king of Mycenae.
