"One Ring to rule them all, One Ring to find them, One Ring to bring them all and in the darkness bind them. In the Land of Mordor where the Shadows lie." Everyone knows that Sauron made the One Ring, but nobody—including Tolkien—seems to know how it worked, perhaps because nobody—including Tolkien—explained how Sauron made it. Where did Tolkien get the idea of magic rings? What would it mean to make a magic ring? And what might explain its effects? In this lecture, Professor Rachel Fulton Brown gives a brief history of English magic in quest of the making of Sauron's One Ring and explores the spiritual dangers in attempting to make such rings for Elves, Dwarves, Hobbits—and Men.
