Clad in a tunic, a barefoot woman strides out of the stadium tunnel at a recent revival of the Nemean Games. In 1995, a group decided to bring back the ancient athletic festival, allowing participants to change in the apodyterion, oil their bodies and proceed through the tunnel to the arena—just as athletes did in the fourth century B.C. About 1,900 people now belong to the Society for the Revival of the Nemean Games, which will hold the third Nemead beginning on July 31.
