ATHENS, Greece -- Wrestling is a really ancient sport. It has been documented in prehistoric cave paintings. There are literary allusions of wrestling matches in 13th century BC, when the Greeks besieged Troy. It was a staple of the ancient Olympics, having been introduced at the 18th Olympiad, in 708 BC, and remained at the program until the very end, 273 Games later. It was a part of the modern revival of the Olympics in 1896 and has been held at every Games since. Yet, wrestling's many practitioners around the world are hoping it won't be history anytime soon.This weekend, more than 100 wrestlers, men and women, from 12 countries, as well as top officials of the International Federation of Associated Wrestling Styles (FILA) came back to the sport's roots in Ancient Olympia to find inspiration in the place and, perhaps, to consult with the gods on their campaign to keep wrestling in the Olympics.
