After Delphi, Dodona was the most important of the oracles in Ancient Greece. The somewhat limited literary references to Dodona's history have been supplemented in recent years by valuable archaeological findings, illustrating particularly its use by private inquirers. In this book, the first time the subject has been treated at length, H. W. Parke examines in detail the chief problems concerning Dodona's activity and assesses all the available evidence while clearly distinguishing between what is certain, what is probable, and what is merely speculative. He combines his analysis with studies of Olympia and Ammon, the two other sites where the Greeks consulted Zeus.
