The Delphic Seer, also known as the ORACLE of Delphi, was an ancient Greek priestess who served as a seer and prophet. She was believed to be able to provide divinely inspired prophecies and advice to those who sought her counsel. The ORACLE of Delphi was consulted by many of the most powerful figures in ancient Greece, including kings, generals, and philosophers. The term 'Delphic Seer' is derived from the ancient Greek city of Delphi, where the ORACLE was located.
