Organized athletics in Greece traditionally date back to 776 BC, with ongoing activity recorded up to 393 BC. These ancient Olympic Games tested warrior skills and consisted of running, long jump, boxing, wrestling, Pankration (combat sport), discus throw, and javelin throw. In the Bayankhongor Province of Mongolia, Neolithic-era cave paintings dating to 7000 BC depict a wrestling match surrounded by crowds. Prehistoric cave-paintings in Japan show a sport similar to sumo wrestling. In Wadi Sura, near Gilf Kebir in Libya, a Neolithic rock painting in the cave of swimmers shows evidence of swimming and archery being practiced around 6000 BC.
