The daughter of Pleisthenes and Aerope, and sister
and Menelaus. She was married to king Strophius
of Crissa, with whom she had a son and a daughter: Pylades and Astydameia.
Pylades grew up with his cousin Orestes, who had been sent to Crissa by his sister Electra to avoid the torments of their mother Clytemnestra and her lover Aegisthus. Pylades was later to marry Electra after Agamemnon had been revenged and Orestes acquitted for killing his mother.
Apart from losing her brother Agamemnon, Anaxibia was the only of Atreus' children who escaped the curse of the family.
