Beowulf the king of the Danes, whose mead hall in Heorot has been under attack by a monster known as Grendel. After Beowulf slays him, Grendel's mother attacks the hall and is then also defeated. Victorious, Beowulf goes home to Geatland (Götaland in modern Sweden) and later becomes king of the Geats. After a period of fifty years has passed, Beowulf defeats a dragon, but is mortally wounded in the battle. After his death, his attendants cremate his body and erect a tower on a headland in his memory. The full story survives in the manuscript known as the Nowell Codex.
The dragon (Beowulf) referred to in language which is meant to recall the powers of darkness which Christian men felt themselves to be encompassed. They are 'inmates of hell', 'adversaries of God', 'offspring of Cain', 'enemies of mankind'...And so Beowulf, for all that he moves in the world of the primitive Heroic Age of the Germans, nevertheless is almost a Christian knight". Peter Gainsford noted in the article "The Deaths of Beowulf and Odysseus: Narrative Time and Mythological Tale Types" that "In the twenty-first century "Beowulf" does not lack for commentators to defend the literary merit of the dragon episode".
