In the first months of the writing of a sequel to The Hobbit, in an untitled chapter that became ‘The Shadow of the Past,’ Tolkien pictured an opening scene in Bag-End. Gandalf is speaking about the magic rings made by the Necromancer and distributed to various folk of Middle-earth:
The dwarves it is said had seven, but nothing could make them invisible. In them it only kindled to flames the fire of greed, and the foundation of each of the seven hoards of the Dwarves was a golden ring. (Shadow 78).
At this early point of composition the magic ring was imagined as made by the Necromancer but had not yet become the One Ring. Once it did so, the association of magic rings and dwarf treasure was transformed into the following idea, voiced by Elrond as he tells the history of Sauron and the Rings of Power at the great Council of Rivendell:
His Ring was lost but not unmade. The Dark Tower was broken, but its foundations were not removed; for they were made with the power of the Ring, and while it remains they will endure.
Unlike the usual sequence from draft to published story, in this case the final version of the idea reveals its origin and so illuminates the meaning of the abandoned draft conception.
The idea is given different shapes by different drawings of the role of the magic ring in the story of Bilbo Baggins (1930-1933) in relation to the symbol of the tower that appears in ‘The Fall of Númenor’ (1936).
As detailed in various entries, The Hobbit tells a story of how a hobbit is named a burglar, thereby revealing a latent meaning of the ancient English phrase þéof náthwylces found in Beowulf. As such, the story helps Tolkien read the riddle of an expression that is now mythical because it belongs to stories once told but lost in the historical fall that saw the English migrate to the British Isles.
The Hobbit is in just this sense a tower of the kind erected by the exiles of Númenor – the view from the story reveals the meaning of prelapsarian words. Hence, the same logic that allowed Tolkien to name Beowulf a tower in his British Academy lecture also allows The Hobbit to be given this metaphorical or story title.
However, The Hobbit generates its own metaphor or symbol of philological speculation in the form of a magic ring. Where the tower pictures the end of philological inquiry the magic ring pictures its method: when the magic ring becomes Bilbo’s property his essential properties (luck and vanishing) are revealed by story-vision, thereby explaining how the story sticks the name burglar on him.
The magic ring is a metaphorical picture of the method of investigation. The method is the imagination of a story that reveals the hidden connection between the words of the expression; and the magic ring is the vision of such story-making.
On the foundation of this story-vision, a story is constructed, the view from which reveals the lost meaning of the archaic expression. The magic ring provides the foundation of a tower looking over the sea.
Yet this overt connection between magic ring and tower had not been made by Tolkien in winter 1938 when he penned Gandalf’s statement that each dwarf treasure was founded on a magic ring. What we see here, then, is Tolkien attempting to remake the 1936 metaphor of the tower from within The Hobbit.
Making a magic ring the foundation of the treasure of Thror is interesting because studded with ambivelance. The meaning of the treasure of Thror changes in the last part of The Hobbit. By the end of the story (and as pictured with a heavy hand in the movies), the treasure works an enchantment on dwarves and elves who almost go to war over it – an enchantment of the same baleful kind as the Silmarils, which lead the elves to slay their kin in early days of myth. Yet the treasure of the dwarves is also at the heart of their music, which wakes up Bilbo’s Tookish side at the start of the story in Bag-End.
Reflection on this passing relationship between ring and dwarf treasure highlights an intermediate step in the transformation of magic ring into One Ring. As soon as the magic ring was imagined as made by the Necromancer, which is almost the second thought Tolkien had once he began a sequel, it became evil. Nevertheless, for several months of composition the magic ring remained but one of many made by the Necromancer long ago, and for the same period Bilbo’s heir was a madcap prankster named Bingo Bolger-Baggins and Tolkien believed that his jokes would keep the evil of the Necromancer in check. This first phase of the imagination of the sequel hit reality on Weathertop, and this aborted projection of the tower into the treasure of Thror reflects a pre-Weathertop idea of the sequel.
The precise passage of ideas remains unclear to me, but it was on the way to Weathertop that a passing historical observation about Elendil introduced ‘The Fall of Númenor’ into the new hobbit story. Everything changed on Weathertop, but in the first instance this was because Bingo was stabbed by “the sword of the Necromancer” and began to become a wraith – and it became all too clear that the Necromancer was not to be escaped by japes and high spirits. Yet from this point ideas of Númenor began to enter the story. And very soon after this, the magic ring became the One Ring. (Hence, the legend of Elendil found in the myth of Númenor now generated a son, Isildur, who served to get the One Ring from Sauron’s hand to Gollum’s.)
From this point in the composition on it was perhaps only a question of time when the One Ring would be named the foundation of the Dark Tower of the Necromancer.
This, of course, was to invert the original if latent connection, such that a magic ring founds a tower looking over the sea. Barad-dûr provides a platform from which the Eye of Sauron looks out, not over the sea, but over Middle-earth. But this inversion was straightforward given the presence of a white tower by the sea to the west of the Shire, an identification (in the essay On Fairy-stories) of the Magician or Necromancer as the moral opposite of the teller of elvish stories, and the implicit thought that The Lord of the Rings was composed by means of an enchanted ring (the relationship of which to the original magic ring that reveals a hobbit being just what this index wishes to reveal).
