J.R.R. Tolkien helped popularize Beowulf through his 1936 lecture and essay “Beowulf: The Monsters and the Critics.”
Before Tolkien’s intervention, Beowulf was often treated mainly as a source of historical information about Germanic society or as a damaged relic of early English literature. Tolkien argued that the poem should be read as a work of art. He emphasized the importance of its monsters, especially Grendel and the dragon, and defended the poem’s carefully balanced structure.
The lecture was delivered at Oxford in 1936 and published as an essay in 1937. It became one of the most influential pieces of modern Beowulf criticism. Tolkien’s argument helped shift scholarly attention toward the poem’s themes, imagery, and artistic unity.
His interest in Beowulf also influenced his fiction. Dragons, heroic reputations, treasure, ancient swords, and the tension between courage and mortality recur throughout Middle-earth. Tolkien translated Beowulf into modern English, but that translation was published posthumously, long after the 1936 lecture had established his critical importance.
