Nemean Games
When the army of the Seven against Thebes was passing through Nemea on its way to Thebes, Lycurgus' infant son Opheltes was killed by a serpent, through the negligence of his nursemaid Hypsipyle. The child's funeral games were said to have been the origin of the Nemean Games and Lycurgus' tomb was said to be in the grove of Nemean Zeus.
