Mythic, worshipped in ancient Greece, dates vary, beginning circa 1600 B.C.E.
Python was a Greek serpent goddess and a daughter of Gaea. She guarded the oracle of Delphi on Mount Parnassus until she was slain by Apollo, who claimed the oracle as his own. To commemorate his victory, the Pythian games were initiated and held every four years in Delphi. These games were a precursor to the modern Olympics.
