plays music in the background of a boxing match (
Attic vase, 510–500 BC) Since the poets most often call their victory songs
hymnoi (), it has been conjectured that
hymns for
Heracles, honored as the founder of the
Olympic Games, were the original model for the athletic
epinikion. Victory odes are also associated with the
Dioscuri; Pindar uses the term "Castor-song" (), and Polydeuces (Pollux), the mortal twin of Castor, was a
boxer. Although the best-known
epinikia appear to have been composed for a chorus, they may have originally been performed by a soloist. Pindar says that a
lyric by
Archilochus was sung at Olympia, and a
scholiast to the passage gives a quotation. The performance of these songs seems to have led in the 6th century BC to aristocratic commissions for more elaborate numbers. 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. '' ==Occasion and performance==
