The Silmarillion

The Silmarillion is a collection of J. R. R. Tolkien's mythopoeic works, edited and published posthumously by his son Christopher Tolkien in 1977, with assistance from Guy Gavriel Kay, who later became a noted fantasy writer. The Silmarillion, along with J. R. R. Tolkien's other works, forms a comprehensive, yet incomplete, narrative that describes the universe of Middle-earth within which The Hobbit and The Lord of the Rings take place.

After the success of The Hobbit, and prior to the publication of The Lord of the Rings, Tolkien's publisher requested a sequel to The Hobbit, and Tolkien sent them an early draft of The Silmarillion. But through a misunderstanding, the publisher rejected the draft without fully reading it, with the result that Tolkien began work on "A Long Expected Party", the first chapter of what he described at the time as "a new story about Hobbits", which became The Lord of the Rings.

The Silmarillion comprises five parts. The first part, Ainulindalë, tells of the creation of Eä, the "world that is". Valaquenta, the second part, gives a description of the Valar and Maiar, the supernatural powers in 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 the Silmarils which 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 the Rings of Power and the Third Age, is a brief account of the circumstances which led to and were presented in The Lord of the Rings.

The five parts were initially separate works, but it was the elder Tolkien's express wish that they be published together. Because J. R. R. Tolkien died before he finished revising the various legends, Christopher gathered material from his father's older writings to fill out the book. In a few cases, this meant that he had to devise completely new material in order to resolve gaps and inconsistencies in the narrative.
