The Pythian Games were one of the four Panhellenic Games of Ancient Greece. Founded circa the 6th century BCE, the festival was held in honor of the god Apollo and took place at his sanctuary in Delphi to commemorate the mytho-historic slaying of Python and the establishment of the Oracle at Delphi. The Pythian Games took place every four years, two years after the Olympic Games, and between each Nemean and Isthmian Games. They continued until the 4th century AD.
