Diagoras of Rhodes was a boxer who embodied every quality of the noble ancient athlete. Diagoras was victorious in not only the Olympic games, but in every other major Greek athletic festival as well. The extent and number of his triumphs certainly contributed to his fame, but the virtuous character of Diagoras was as important to the ancient Greeks as his success as a boxer.

We know that Diagoras' family was of the noble, ruling class on Rhodes, and the Rhodians claimed that the boxer was the son of the god Hermes. Such legends were a common means of explaining how mortal men could perform "super-human" athletic achievements.

In his Ode for Diagoras, Olympian 7, Pindar praises the boxer as a "fair-fighter" and a "gigantic" man. Diagoras also "walks a straight course on a road that hates arrogance." In addition to his Olympic victory, Diagoras won four times at the Isthmian games, twice at Nemea, and at other games held in his native Rhodes, Athens, and elsewhere throughout the Greek world. We have no exact record of his career, but it is clear that Diagoras was a legend in his own time.

Diagoras lived to witness the Olympic victories of his two sons Damagetos and Akousilaos. At the 83rd Olympiad in 448 BCE, Damagetos won the second of his two prizes for the pankration, and Akousilaos won the boxing victory. Then, the sons carried their father on their shoulders while the crowd showered them with flowers and congratulated Diagoras on his sons. Another of his sons, Dorieus, won three successive Olympic titles in the pankration, along with eight Isthmian victories and seven at Nemea. Two of the sons of Diagoras' daughters were also Olympic boxing champions.

Three generations of Diagoras' family were crowned Olympic champions, adding to the fame that the boxer won in his own right and no doubt fueling other legends of the immortal ancestry of the Diagoras family. Even baseball's Griffey and Ripken families fall a generation short of imitating the achievements of Diagoras, his sons, and grandsons.
