cornucopia (kôrˌnyōkōˈpēə) [key], in Greek mythology, magnificent horn that filled itself with whatever meat or drink its owner requested. Some legends designate it as a horn of the river god Achelous, others as a horn of the goat Amalthaea. It is often represented as filled with fruits and flowers and has become the symbol of plenty.
