It was almost evening at the Nemean Games when Creugas from Epidamnus and Damoxenus from Syracuse were boxing. So they agreed that they would each allow the other on free punch to decide the match. In those times the boxers wore soft gloves and their fingers were left uncovered. Creugas started and punched Damoxenus in the head. Damoxenus then asked his opponent to raise his arm. No sooner had Creugas raised his arm, than Damoxenus used his straightened fingers to strike right under his rib-cage. It was such a hard hit and because he had sharp fingernails that his hand went into his opponent’s body where he grabbed intestines and tore them out with force.
However Creugas, now dead, was declared the victor by the judges because they considered the blow from each of Damoxenus’ fingers as an individual punch even though they had agreed on one punch.
