The first complete version of The Silmarillion was the Sketch of the Mythology written in 1926 (later published in Volume IV of The History of Middle-earth). The Sketch was a 28-page synopsis written to explain the background of the story of Túrin to R. W. Reynolds, a friend to whom Tolkien had sent several of the stories. 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.
