A place in Epirus, northwestern Greece. It is the location of the oldest oracle of Greece (Hellas) and is sacred to Zeus and his consort Dione. Its priests, called Selloi, who were forbidden to wash their feet, interpreted the rustling of a great oak as the will of Zeus. It was consulted by Greeks and foreigners alike and was second only to the oracle of Delphi.
The shrine was destroyed by the Aetolians in 219 BCE but was probably restored later.
