|Pindarus, Ol. ode 7, 15-17 & 80-86
I may praise, in recompense of his boxing,
… athletic contests, with whose flowers Diagoras
The bronze in Argos came to know him, as did the works
(transl. W. Race)
The victories at the Alpheios river and the Kastalia source refer to his Olympic and Pythian victories. In the second fragment he refers first to local games on Rhodos - where Diagoras came from -, then to the more famous Isthmian, Nemean and Panathenaic games and then to some smaller local games.
