A long heroic poem is a type of literature that has been around for centuries. It is usually written in an elevated style and tells a story of great deeds or events. The two most common terms used to describe this type of poem are 'EPIC' and 'epos'. An EPIC is a long narrative poem, usually on a grand scale, that celebrates the deeds of a legendary or traditional hero. An epos is a long narrative poem, usually on a grand scale, that is composed in a formal, elevated style.
