Beowulf is never name by Gardner to emphasize he does not belong to Hrothgar's society.
Explanation:
Being unnamed, Beowulf has a halo of mystery and sparkles the reader’s curiosity about him. He is a Geatish warrior coming across the sea, so he remains an outsider even when he defeats Grendel. By using a nameless hero, Gardner is also preventing the reader from attaching him to the Danish society. It is said that Beowulf’s name precedes him so Hrothgar and his people already know him. Thus, his impressive deeds are far more important than his name.
