From the "Sketch" Tolkien developed a fuller narrative version of The Silmarillion called Quenta Noldorinwa (also included in Volume IV). The Quenta Noldorinwa was the last version of The Silmarillion that Tolkien completed. In 1937, encouraged by the success of The Hobbit, Tolkien submitted to his publisher George Allen & Unwin an incomplete but more fully developed version of The Silmarillion called Quenta Silmarillion, but they rejected the work as being obscure and "too Celtic". The publisher instead asked Tolkien to write a sequel to The Hobbit. Tolkien began to revise The Silmarillion, but soon turned to the sequel,

The first, Ainulindalë, tells of the creation of Eä, the "world that is." The second part, Valaquenta, gives a description of the Valar and Maiar, supernatural powers of Eä. The next section, Quenta Silmarillion, which forms the bulk of the collection, chronicles the history of the events before and during the First Age, including the wars over three jewels, the Silmarils, that gave the book its title. The fourth part, Akallabêth, relates the history of the Downfall of Númenor and its people, which takes place in the Second Age. The final part, Of

Content:  In 1998, the German power metal band Blind Guardian released a concept album about the events in the book titled Nightfall in Middle-Earth. The Norwegian classical composer Martin Romberg has written three full-scale symphonic poems, "Quendi" (2008), "Telperion et Laurelin" (2014), and "Fëanor" (2017), inspired by passages from The Silmarillion. The works were premiered by orchestras in Southern France between 2009 and 2017. The British rock band Marillion and the French black metal band Hirilorn (which later evolved into Deathspell Omega) took their names from the book.
Title: The Silmarillion
Content:  The Silmarillion is a collection of mythopoeic stories by the English writer J. R. R. Tolkien, edited and published posthumously by his son Christopher Tolkien in 1977 with assistance from the fantasy author Guy Gavriel Kay. The Silmarillion tells of Eä, a fictional universe that includes the Blessed Realm of Valinor, the once-great region of Beleriand, the sunken island of Númenor, and the continent of Middle-earth, where Tolkien's most popular works—The Hobbit and The Lord of the Rings—take place. After the success of The Hobbit, Tolkien's publisher Stanley Unwin requested a sequel, and Tolkien offered a draft of the stories that would later become The Silmarillion. Unwin rejected this proposal, calling the draft obscure and

The Quenta Silmarillion of the 1930s was Tolkien's final text for this section, and Christopher carried it forward into The Silmarillion nearly word for word with editorial modifications—for consistency with other works—primarily limited to nomenclature: Fionwë edited to Eönwë, Lindar to Vanyar, etc. For example: "From The Silmarillion: 'In the front of that fire came Glaurung the golden, father of dragons, in his full might; and in his train were Balrogs, and behind them came the black armies of the Orcs in multitudes such as the Noldor

Title: J. R. R. Tolkien
Content:  Tolkien wrote a brief "Sketch of the Mythology", which included the tales of Beren and Lúthien and of Túrin; and that sketch eventually evolved into the Quenta Silmarillion, an epic history that Tolkien started three times but never published. Tolkien desperately hoped to publish it along with The Lord of the Rings, but publishers (both Allen & Unwin and Collins) declined. Moreover, printing costs were very high in 1950s Britain, requiring The Lord of the Rings to be published in three volumes. The story of this continuous redrafting is told in the posthumous series The History of Middle-earth, edited by Tolkien's son, Christopher Tolkien. From around 1936, Tolkien began to extend this framework to include the tale of The Fall of Númenor, which was inspired by the legend of Atlantis. Tolkien appointed his son Christopher to be his literary executor, and he (with assistance from Guy Gavriel Kay, later a well-known fantasy author in his own right) organized some of this material into a single coherent volume, published as The Silmarillion in 1977. It received the Locus Award for Best Fantasy novel in 1978.
Title: The Silmarillion
Content:  At the time of release, reviews of The Silmarillion were generally negative. The Tolkien scholar Wayne G. Hammond records that the book's publisher, Rayner Unwin, called the reviews "among the most unfair he had ever seen". The book was a commercial success, topping The New York Times Fiction Best Seller list in October 1977. It won the Locus Award for Best Fantasy Novel in 1978. The Silmarillion was criticized for being too serious, lacking the light-hearted moments that were found in The Lord of the Rings and especially The Hobbit. Time magazine lamented that there was "no single, unifying quest and, above all, no band of brothers for the reader to identify with". Other criticisms included difficult-to-read archaic language and many difficult and
