The Oracle of Apollo, most famously known as the Oracle of Delphi, is a figure from Greek mythology which refers to a priestess (known as the Pythia) who served as a medium through which Apollo, the god of prophecy, spoke. These prophesies were considered highly reliable and authoritative, and they played a major role in Greek politics, religion, and daily life. The Oracle of Apollo was based in the Temple of Apollo at Delphi, a significant site of worship and pilgrimage in ancient Greece. Each oracle’s pronouncements were believed to be the responses of Apollo to specific questions asked by individuals or states.
