He sent two eagles flying from the eastern and western extremities, and the path of the eagles crossed over Delphi where the omphalos, or navel of Gaia was found.
include traditions that Pythia, or the Delphic oracle, already was the site of an important oracle in the pre-classical Greek world (as early as 1400 BC) and, rededicated from about 800 BC, when it served as the major site during classical times for the worship of the god Apollo.
After the battle of Plataea, the Greek cities extinguished their fires and brought new fire from the hearth of Greece, at Delphi; in the foundation stories of several Greek colonies, the founding colonists were first dedicated at Delphi.
Apollo is connected with the site by his epithet Δελφίνιος Delphinios, "the Delphinian".
The epithet is connected with dolphins (Greek δελφίς,-ῖνος) in the Homeric Hymn to Apollo (line 400), recounting the legend of how Apollo first came to Delphi in the shape of a dolphin, carrying Cretan priests on his back. Another legend held that Apollo walked to Delphi from the north and stopped at Tempe, a city in Thessaly, to pick laurel (also known as bay tree) which he considered to be a sacred plant.
In commemoration of this legend, the winners at the Pythian Games received a wreath of laurel picked in the Temple.
Apollo was said to have slain Python, a "drako" a serpent or a dragon who lived there and protected the navel of the Earth.
Erwin Rohde wrote that the Python was an earth spirit, who was conquered by Apollo, and buried under the Omphalos, and that it is a case of one deity setting up a temple on the grave of another.Delphi would have been a renowned city whether or not it hosted these games; it had other attractions that led to it being labeled the "omphalos" (navel) of the earth, in other words, the centre of the world.In the inner hestia (hearth) of the Temple of Apollo, an eternal flame burned.The "Theoxenia" was held each summer, centred on a feast for "gods and ambassadors from other states".Myths indicate that Apollo killed the chthonic serpent Python, Pythia in older myths, but according to some later accounts his wife, Pythia, who lived beside the Castalian Spring.It occupies an impressive site on the south-western slope of Mount Parnassus, overlooking the coastal plain to the south and the valley of Phocis.
