An epic is a long poem that has several characteristics:
- a hero or heroes who embody the values of the society
- usually begins with an invocation to a Muse
- gods/goddesses who intervene on behalf of the humans
- a vast setting so the hero can go on adventures to foreign lands
- long and formal speeches
- use of epithets
These are most of the main characteristics of an epic. The Odyssey meets these requirements since it includes the hero Odysseus who tries to get home from the Trojan War. In doing so, he finds himself in strange lands and facing horrible enemies, such as Cyclopes and the Sirens.
An epic is a long and narrative poem on a serious subject. The Odyssey is considered an epic because it is greek mythology and is also dated back in the B.C.
