Pythian Games, celebrated from very early times till the 4th century A.D. every four years, near Delphi, in honour of Apollo, who was said to have instituted them to commemorate his victory over the Python; originally were contests in singing only, but after the middle of the 6th century B.C. they included instrumental music, contests in poetry and art, athletic exercises, and horse-racing.
