An oracle (Greek: χρησμός) refers primarily to a person or agent who claims to have prophetic gifts and be able by a deity holding a whispered message across, whether it refers to that statement itself. The term oracle is thus used both for the wise counsel of (or more) alleged deities, as the place or person where that advice was taken.
