The location of the incident is located in the Agora of Athens (ancient Athens) but it is unclear where the contest took place.
Dioxippus (Διόξιππος) was an ancient Greek pankratiast, renowned for his Olympic victories in the sport of pankration. His fame and skill were such that he was crowned Olympic champion by default in 336 BC when no other pankratiast dared meet him on the field. This kind of victory was called "akoniti" (literally: without getting dusted) and remains the only one ever recorded in the Olympics in this discipline. The most famous story of Dioxippus is his victory over Coragus of the Macedonian Army.
