In Greek mythology, Apollo was the Olympian god associated with the oracle at Delphi.
The Delphic oracle operated at the Temple of Apollo, on the slopes of Mount Parnassus. Its priestess, called the Pythia, delivered prophecies after entering a trance, and Greek rulers and visitors consulted her about wars, laws, travel, and religious matters.
Apollo became connected with Delphi after defeating Python, a serpent or dragon that guarded the site in many versions of the myth. The sanctuary was also linked to Apollo’s roles as a god of prophecy, music, healing, and archery.
A common mix-up is confusing Delphi with Dodona, another famous Greek oracle. Dodona was especially associated with Zeus, while Delphi was the principal sanctuary of Apollo. The Pythian Games, held at Delphi, honored Apollo through music and athletic competitions.
