Delphi, a town of ancient Greece in Phocis, at the foot of Parnassus, where Apollo had a temple, and whence he was wont to issue his oracles by the mouth of his priestess the Pythia, who when receiving the oracle used to sit on a tripod over an opening in the ground through which an intoxicating vapour exhaled, deemed the breath of the god, and that proved the vehicle of her inspiration; the Pythian games were celebrated here.
