Delphi, in legend previously called Pytho (Πυθώ), in ancient times was a sacred precinct that served as the seat of Pythia, the major oracle who was consulted about important decisions throughout the ancient classical world. The oracle was international in character and also fostered sentiments of Greek nationality, even though the nation of Greece was centuries away from realization. The ancient Greeks considered the centre of the world to be in Delphi, marked by the stone monument known as the omphalos (navel). The sacred precinct was in the region of Phocis, but its management had been taken away from the Phocians, who were trying to extort money from its visitors, and had been placed in the hands of an amphictyony, or committee of persons chosen mainly from Central Greece. According to the Suda, Delphi took its name from the Delphyne, the she-serpent (drakaina) who lived there and was killed by the god Apollo.

The Temple of Apollo, god of music, harmony, light, healing, and oracles occupied the most important and prominent position in the Delphic Panhellenic Sanctuary. The edifice with the partially restored colonnade visible today dates to the 4th century BC; it is the third temple built at the same place. The famous oracle, the Pythia, operated inside the temple, the location chosen, according to one tradition, due to a sacred chasm beneath the site emitting vapors, which were inhaled by the Pythia. Some ancient writers state that the Pythia then entered a state of delirium and uttering inarticulate cries, which were then turned into equivocal oracles by the priests. This interpretation is controversial, and has been challenged by scholars such as Joseph Fontenrose and Lisa Maurizio, who argue that the ancient sources uniformly represent the Pythia speaking intelligibly, and giving prophecies in her own voice.

Abae was an ancient town in the northeastern corner of ancient Phocis, in Greece, near the frontiers of the Opuntian Locrians, said to have been built by the Argive Abas, son of Lynceus and Hypermnestra, and grandson of Danaus.

The site of the oracle was rediscovered at Kalapodi and excavated in modern times. The results confirm an archaeological existence dating from the Bronze Age, as is suggested by the lore.
