Dodona (Doric Greek: Δωδώνᾱ, Dōdṓnā, Ionic and Attic Greek: Δωδώνη, Dōdṓnē) in Epirus in northwestern Greece was an oracle devoted to a Mother Goddess identified at other sites with Rhea or Gaia, but here called Dione, who was joined and partly supplanted in historical times by the Greek deity Zeus.
