J. R. R. Tolkien
The request for a sequel prompted Tolkien to begin what would become his most famous work: the epic novel "The Lord of the Rings" (originally published in three volumes 1954–1955). Tolkien spent more than ten years writing the primary narrative and appendices for "The Lord of the Rings", during which time he received the constant support of the Inklings, in particular his closest friend C. S. Lewis, the author of "The Chronicles of Narnia". Both "The Hobbit" and "The Lord of the Rings" are set against the background of "The Silmarillion", but in a time long after it.
Themes of The Lord of the Rings
Since the publications of J. R. R. Tolkien's "The Lord of the Rings", "The Hobbit" and "The Silmarillion", a wealth of secondary literature has been published discussing the literary themes and archetypes present in the stories. Tolkien also wrote about the themes of his books in letters to friends, family and fans, and often within the books themselves. In his Foreword to the Second Edition of "The Lord of the Rings", Tolkien said that he "disliked allegory in all its forms" (using the word "applicability" instead), and told those claiming the story was a metaphor for World War II to remember that he had lost "all but one" of his close friends in World War I.
