An epic in literature is a long narrative poem that tells the story of heroic deeds and adventures. It can be written in verse or prose and is typically novel-length. Epics can deal with various subjects such as myths, heroic legends, histories, religious tales, animal stories, or philosophical or moral theories. The term "epic" is often used to describe a certain kind of heroic oral poetry that comes into existence in so-called heroic ages. The elements that typically distinguish epics include superhuman deeds, fabulous adventures, highly stylized language, and a blending of lyrical and dramatic traditions. The prime examples of the oral epic are Homer’s Iliad and Odyssey. Many of the world’s oldest written narratives are in epic form, including the Babylonian Gilgamesh, the Sanskrit Mahâbhârata, and Virgil’s Aeneid. The effect of epics was to commemorate the struggles and adventures of the hero to elevate their status and inspire the audience.
