Eukles was the grandson of Diagoras and the son of Akousilaos, who won the Olympic boxing championships in 464 and 448 BCE. To this time, women were never permitted at Olympia and were put to death if they were discovered watching the events. Eukles’ mother attended his matches, however, disguised as a trainer. When he won, she leaped over the barrier behind the trainer’s station and exposed herself as a woman. The judges withheld the death penalty “out of respect for her father and her brothers and son.” However, a rule was enacted requiring all trainers to thereafter attend all Olympic contests fully naked, like the athletes.
