The Silmarillion is Tolkien’s first book and his last. Long preceding in its origins The Lord of the Rings, it is the story of the First Age of Tolkien’s world, the ancient drama to which characters in The Lord of the Rings look back, and in which some of them, such as Elrond and Galadriel, took part. The Silmarillion was begun in 1917, and Tolkien worked on it, changed it, and enlarged it throughout his life. Edited by his son, Christopher Tolkien, the book finally appeared four years after the author’s death.
