Pherenikos (Greek: Φερένικος; Latin: Pherenicus) was an Ancient Greek chestnut racehorse victorious at the Olympic and Pythian Games in the 470s BC.
 Pherenikos, whose name means "victory-bearer", was "the most famous racehorse in antiquity".
 Owned by Hieron I, tyrant of Syracuse, Pherenikos is celebrated in the victory odes of both Pindar and Bacchylides.
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.
