* Epic Poems: These are long narrative poems that celebrate heroic deeds and often involve supernatural elements. *Beowulf* follows the titular hero's journey to defeat monstrous creatures and protect the people of Geatland. It utilizes formal language, elevated diction, and a strong emphasis on oral storytelling traditions.
* Novels: These are longer works of fiction written in prose. *Grendel*, by John Gardner, reimagines the classic *Beowulf* story from the monster's perspective, offering a philosophical and psychological exploration of good and evil. Its language is more modern and colloquial, and it delves into complex themes and ideas that are not present in the original epic poem.
Therefore, the genre difference impacts the style, tone, themes, and overall approach to storytelling in each work.
