Adon ??d?n [key], in Greek legend, the wife of Zethus, king of Thebes. She had only one son, while her sister-in-law, Niobe, had many. Her jealousy increased until, in trying to murder Niobe's oldest son, she killed her own child. She was changed to a nightingale, and her song was a mournful call for her son, Itys or Itylus.
