Tolkien’s ring of power is a plain gold ring, of course, and embodies a series of quite complex valences to do with binding, with vows and marriage. But at the same time as being a blank surface, the ring is also paradoxically (which is to say, magically) lettered. The ring, in other words, is a book. To be sure it is a short book; its whole text is the one ring charm. But a short book is still a book. Looked at this way, Lord of the Rings becomes a strangely self-destructive fable—a book about the quest to destroy a book, a long string of carefully chosen words positing a world in which words have magical power to huge evil. How few books there are in Middle Earth! Indeed, I’ve written elsewhere about not just the paucity of written texts in Tolkien’s world, but the way they keep getting misread. Gandalf scratches his rune at Weathertop; the hobbits misread it. The elven door in Moria, beautifully lettered, commands ‘speak friend and enter!’ and nobody understands its simple instruction. The fellowship find a dwarfish book in the mines, as scorched and battered as poor old Beowulf; but as they read it aloud (‘drums in the deep’, ‘we cannot get out’) it becomes true to them, and they repeat the words as suddenly, horribly, appropriate to their own predicament. The repeated theme is the danger of words; their slipperiness but also the ease with which they can move us directly into the malign world of the text. One ring to bind us all. Books are bound, too.
