The Pythian Games were one of the four Panhellenic Games of Ancient Greece. They were held in honour of Apollo at his sanctuary in Delphi every four years, two years after the Olympic Games, and between each Nemean and Isthmian Games. The Pythian Games were founded sometime in the 6th century BC. In legend they were started by Apollo after he killed Python and set up the Oracle at Delphi. They continued until the 4th century AD.
