The oracle at Dodona was the oldest in Greece, with only Delphi rivaling it in prestige. There was a main temple, probably dedicated to Zeus and Dione, with several smaller temples around the site. (At least one, near the theatre, had dedications to Aphrodite, Dione’s daughter by Zeus, according to local myth.)
Dione, whose name means Divine or Goddess, is mainly known as Aphrodite’s mother, but she had her own cult, centred around the oracle at Dodona. She was probably a Mycenean goddess, but her origin is somewhat mysterious.
