and "the book by J. R. R. Tolkien that rules them all". Analysis A challenge to complete Academic criticism of Christopher Tolkien's 1977 text concentrated on his father's intention to complete the work: Since he did not do so, his plans for the overall narrative, out of the large collection of draft texts, were not clearly discernible. That in turn meant, argued the Tolkien scholar Charles Noad, that Silmarillion criticism ought first to "evolve approaches to this textual complex as it [was], including Christopher Tolkien's 1977 Silmarillion". Gergely Nagy writes that The Silmarillion is long both in Middle-earth time and in years of Tolkien's life; and it provides the impression of depth for both The Hobbit and The Lord of the Rings. It is however in his view "immensely problematic" as it is not a "work" as usually understood: "The Silmarillion" (in roman) is the enormous corpus of documents and drafts that J. R. R. Tolkien built up throughout his creative life, while "The Silmarillion" (in italics) is the 1977 book that Christopher Tolkien edited. The corpus is now published in the twelve volumes of Christopher Tolkien's The History of Middle-earth. The corpus is not a single work but many versions of many works, while the book "is often regarded as not an authentic 'Tolkien text'". Tolkien did not authorise the 1977 text; he did not even write all of it; and he did not define the frame in which it was to be presented. Nagy notes that in 2009, Douglas Charles Kane published a "hugely important resource", his Arda Reconstructed, which defines "exactly from what sources, variants, and with what methods" Christopher Tolkien constructed the 1977 book. A presented collection Verlyn Flieger analyses at length Tolkien's way of thinking of his own mythology as a presented collection, with a frame story that changed over the years, first with a seafarer called Eriol or Ælfwine who records the sayings of the "fairies" or translates the "Golden Book" of the sages Rumil or Pengoloð; later, he decided that the Hobbit Bilbo Baggins collected the stories into the Red Book of Westmarch, translating Elvish documents in Rivendell. Nagy observes that this means that Tolkien "thought of his works as texts within the fictional world" (his emphasis), and that the overlapping of different accounts was central to his desired effect. Nagy notes that Tolkien went so far with his artwork as to create
