These were held in the sanctuary of *Zeus at *Nemea (1). They were said to have been founded by *Adrastus (1) of *Argos (1), in memory of the child Opheltes, killed there by a snake during the expedition of the *Seven against Thebes, or by *Heracles after he had killed the Nemean lion. They were reorganized as a Panhellenic festival in 573 bce, held in July every second and fourth year in each Olympiad, and were at first managed by Cleonae, later by Argos. The prize was a crown of fresh celery.
