Tolkien's Cauldron studies the sources of J.R.R. Tolkien's The Lord of the Rings. Tolkien was a scholar of Old Norse literature and much of his work in the Lord of the Rings is informed by his knowledge of old Norse mythology, Eddic poetry, and saga. Tolkien's use of these sources enriched this complex story of Middle-earth.
