The ancient civilization known for its oracle at Delphi is the Greeks, specifically the ancient city-states of Greece. Delphi was considered the center of the world in Greek mythology and hosted the Pythia, a priestess who served as the oracle. The oracle was consulted by individuals and city-states alike for guidance on matters ranging from governance to warfare. The site attracted pilgrims who sought insights from the divine, and the responses were often cryptic, requiring interpretation. Delphi's significance extended beyond religion, influencing politics, culture, and the arts in ancient Greek society, further solidifying its status as a pivotal cultural and spiritual landmark.
