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 is perhaps best known for its oracle, the Pythia, the sibyl or priestess at the sanctuary dedicated to Apollo. One tale of the sanctuary's discovery states that a goatherd, who grazed his flocks on Parnassus, one day observed his goats playing with great agility upon nearing a chasm in the rock; the goatherd noticing this held his head over the chasm causing the fumes to go to his brain; throwing him into a strange trance. She had to be an older woman of blameless life chosen from among the peasants of the area.
The culmination of the festival was a display of an image of the gods, usually hidden in the sanctuary, to worshippers.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.formerly also called Pytho (Πυθώ), is famous as the ancient sanctuary that grew rich as the seat of Pythia, the oracle who was consulted about important decisions throughout the ancient classical world.The ancient Greeks considered the centre of the world to be in Delphi, marked by the stone monument known as the omphalos (navel).
