Aedon  (a-ē´dōn ).—Daughter of Pandareus and wife of Zethus, king of Thebes. Jealous of Niobe, her brother Amphion's wife, having six sons and six daughters, while she had but one son, she determined to kill the eldest of Niobe's sons, but by mistake slew her own son Itylus. Jupiter changed her into a nightingale, whose melancholy notes are represented as Ædon's lamentations for her son.
