Dodona is supposedly the location of the oldest oracle in Greece. While Strabo says that the oracle was moved there by the command of Apollo, Herodotus claimed that the arrival of a black dove from Thebes in Egypt into an oak tree at Dodona prompted the oracle. Dodona is mentioned in both the Iliad and the Odyssey. According to Herodotus, the oracle was a woman who interpreted the rustling of the wind in the oak trees as well as the sounds of copper vessels being struck. Like the Pythia at Delphi, the oracle was fabled to enter a trance-like frenzy while delivering her responses to questions written on lead tablets.

Dione, also worshipped at this site, was one of Zeus' many consorts and was a Titaness. Her name is literally the feminine form of Zeus. In some traditions, she was the mother of Aphrodite and she may have once had the role that Hera later filled.

It was also a piece of the oak tree at Dodona that Athena used to make into a magical, speaking prow or figurehead for the Argo, the ship sailed by Jason and the Argonauts.
