Simonides of Ceos
The earliest "epinikia", surviving only in fragments, were composed by Simonides of Ceos in the 520s BC. Simonides was the first professional poet known to write odes in honor of victorious athletes at the games; in antiquity, he was also notorious for being the first poet to charge a fee for his services. The "epinikia" of Bacchylides were formerly considered lost and were known only from quotations in other authors, until the discovery in the late 19th century of a papyrus manuscript containing fifteen of his odes. Pindar's four surviving books of "epinikia", called one of "the great monuments of Greek lyric," correspond to each of the four major festivals of the Panhellenic Games: Olympian, Pythian, Isthmian, and Nemean. Many of Pindar's odes can be identified by event, champion, and year.
