At the foot of Mount Parnassos, within the angle formed by the twin rocks of the Phaedriades, lies the Pan-Hellenic sanctuary of Delphi, which had the most famous oracle of ancient Greece. Delphi was regarded as the centre of the world. According to mythology, it is here that the two eagles sent out by Zeus from the ends of the universe to find the navel of the world met. The sanctuary of Delphi, set within a most spectacular landscape, was for many centuries the cultural and religious centre and symbol of unity for the Hellenic world.
The history of Delphi begins in prehistory and in the myths of the ancient Greeks. In the beginning the site was sacred to Mother Earth and was guarded by the terrible serpent Python, who was later killed by Apollo. Apollo’s sanctuary was built here by Cretans who arrived at Kirrha, the port of Delphi, accompanied by the god in the form of a dolphin. This myth survived in plays presented during the various Delphic festivals, such as the Septerion, the Delphinia, the Thargelia, the Theophania and, of course. the famous Pythia, which celebrated the death of Python and comprised musical and athletic competitions.
The earliest finds in the area of Delphi, which date to the Neolithic period (4000 BC), come from the Korykeion Andron, a cave on Parnassos, where the first rituals took place. The remains of a Mycenaean settlement and cemetery were discovered within the sanctuary, but traces of occupation are rare and very fragmentary until the eighth century BC, when the cult of Apollo was established and the development of the sanctuary and the oracle began. The first stone temples of Apollo and Athena, who was also officially venerated under the name of “Pronaia” or “Pronoia” and had her own sanctuary, were built towards the end of the seventh century BC. According to literary and archaeological evidence other gods were associated with the sanctuary; these included Artemis, Poseidon, Dionysus, Hermes, Zeus Polieus, Hygeia and Eileithyia.
