THE ANCIENT ORACLES
The telling of fortunes and the predicting of the future in ancient times was the work of the Oracles. In the ancient religions the Oracle was believed to be a revelation made by some god or divinity in reply to the questions of men. The word “oracle” was applied both to the answer and to the sacred place where the answer was given. The responses were made either by priests and priestesses or by signs and portents.
At the Oracle of Dodona the responses were given either by the movements of leaves, the noise of brazen vessels, or the murmurings of the waters of a fountain. Usually springs or grottos of which the waters were known to have delirious effects were selected for the sites of the oracles. At Dydima the vapor of the water affected both the priestess and person who consulted her. At Delphi the priestess, who was called the “Pythia,” delivered her utterances from a tripod placed over a chasm, from which intoxicating vapors arose. In some of the oracles, incense and artificial fumigations were used.
