Pleisthenes

Pleisthenes, in Greek mythology, was the son of Atreus and Aerope. According to Hesiod, Pleisthenes married Cleolla, daughter of Dias, and became the father of Agamemnon, Menelaus, and Anaxibia. Aeschylus also followed this tradition when he called the Atreidai "the race of Pleisthenes".
