AEDON

in Greek mythology, a daughter of Pandareus of Ephesus. According to Homer, she was the wife of Zethus, the king of Thebes. She had only two children and envied her sister-in-law, Niobe, who had many. She planned to murder Niobe's eldest son in his sleep, but by mistake killed her own son, Itylus, who was sharing his room. Zeus took pity on Aedon in her grief and changed her into a nightingale; her song was a lament for her dead son.
