Beowulf is the most celebrated poem of the Anglo-Saxon era. It tells the story of a mighty warrior who defends his friends and homeland from lethal threats both human and monstrous. Beowulf's battles with Grendel, Grendel's mother, and an angry dragon are interwoven with scenes of feasts and feuds that provide a view of Scandinavian cultural practices and historical traditions. Though the poem had been absent from the English literary tradition for centuries, Beowulf has become a canonical text in high school and college English courses, thanks in part to J.R.R. Tolkien's study of the poem and his use of it as a source for The Hobbit and The Lord of the Rings trilogy
