were so called from Nemea, a village between the cities of Cleone and Philus, where they were celebrated every third year. The exercises were chariot races, and all the parts of the pentathlon. These games were instituted in memory of Opheltes, or Archemorus, the son of Euphates and Creusa, and nursed by Hypsipyle; who leaving him in a meadow, while she went to slay the besiegers of Thebes a fountain, at her return found him dead, and a serpent twined about his neck; whence the fountain, before called Langes, was named Archemorus; and the captains, to comfort Hypsipyle, instituted these games. Others ascribe their institution to Hercules, after his victory over the Nemean lion.
