A monstrous serpent in Greek mythology, and the child of Gaia, the goddess earth. It was produced from the slime and mud that was left on the earth by the great flood of Deucalion. It lived in a cave and guarded the oracle of Delphi on mount Parnassus.
No man dared to approach the beast and the people asked Apollo for help. He came down from Mount Olympus with his silver bow and golden arrows. With using only one arrow he killed the serpent and claimed the oracle for himself. After that, he was known as Pythian Apollo. In memory of this victory, Apollo started the Pythian games, which were held every four years. The old name of Delphi, Pytho, refers to the serpent.
