Epinikion The epinikion or epinicion (plural "epinikia" or "epinicia", Greek ἐπινίκιον , from "epi-", "on," + "nikê", "victory") is a genre of occasional poetry also known in English as a victory ode. In ancient Greece, the "epinikion" most often took the form of a choral lyric, commissioned for and performed at the celebration of an athletic victory in the Panhellenic Games and sometimes in honor of a victory in war. Major poets in the genre are Simonides, Bacchylides, and Pindar.
Thargelia Thargelia (Greek Θαργήλια) was one of the chief Athenian festivals in honour of the Delian Apollo and Artemis, held on their birthdays, the 6th and 7th of the month Thargelion (about May 6 and May 7).
