 Scholiasts are the only authority for stories about rivalry between Simonides and Pindar at the court of Hieron, traditionally used to explain some of the meanings in Pindar's victory odes (see the articles on Bacchylides and Pindar).If the stories of rivalry are true, it may be surmised that Simonides's experiences at the courts of the tyrants, Hipparchus and Scopas, gave him a competitive edge over the proud Pindar and enabled him to promote the career of his nephew, Bacchylides, at Pindar's expense.However, Pindar scholiasts are generally considered unreliable, and there is no reason to accept their account.
