Aedon (Ἀηδών) is the Greek word for "nightingale." Daughter of Pandareus, who accidentally killed her own son Itylus and was transformed by Zeus into a nightingale — mourning him eternally with her song.
Mentioned in Homer's Odyssey Book 19 — the earliest version of the nightingale myth, predating Philomela.
Aedon reduces to six — the number of Greek nightingale.
