A moment ago you read about the woman who prophesized from Sibyl Rock over 3,000 years ago. By the 8th century BC, her role evolved into the Oracle of Delphi. A priestess who held this title was called Pythia. Her divine power of seeing the future was bestowed by Apollo. Her advice was highly sought by people across the classical world. The Oracle of Delphi followed a strict ritual. She was only available on the 7th day of a month for nine months (excluding winter). She first purified herself in the Castalian Spring while a priest sprinkled holy water on the floor of the Temple of Apollo. She would then be led in a procession to the temple while wearing a purple veil. After a goat was sacrificed and burned at the Altar of Chios, Pythia would meet individually with people who sought her counsel. Their order of admission was based on the size of their donation and then on drawing lots. The Oracle of Delphi ended in the late 4th century AD.
