Step-by-step explanation:
Beowulf is an epic hero in epicc poem with the same title. The epic poem iss one of the oldest surviving texts written in Old English in Anglo-Saxon period.
When Beowulf learns about the terror Grendel has on Herot and Danes people, he decided to go to Herot and fight the monster. Beowulf decides to fight the monster without weapons as he learned that Grendel also does not use one.
