Diagoras of Rhodes was an ancient Greek boxer from the 5th century BC, who was celebrated for his own victories, as well as the victories of his sons and grandsons. He was a member of the Eratidea family at Lalysus in Rhodes. He descended from Damagetus, king of Ialysus, and, on the mother’s side, from the Messenian hero, Aristomenes. Diagoras was victor in boxing twice in the Olympic games, four times in the Isthmian, twice in the Nemean, and once at least in the Pythian Games. The fame of Diagoras and his descendants was celebrated by Pindar (Olympian Odes VII). A local soccer club, Diagoras F.C., and the Rhodes International Airport, “Diagoras” are named after him.
