The Lays of Beleriand gives us a privileged insight into the creation of the mythology of Middle-earth through the alliterative verse tales of two of the most crucial stories in Tolkien’s world – those of Túrin and of Beren and Lúthien. In The Shaping of Middle-earth the chronological and geographical structure of the legends of Middle-earth and Valinor is spread before us. We are introduced to the hitherto unknown Ambarkanta or ‘Shape of the World’, the only account ever given of the nature of the imagined Universe. The Lost Road completes the examination of Tolkien’s writing completes the examination of Tolkien's writing before he began The Lord of the Rings, presenting later forms of the annals of Valinor and Beleriand, the legend of the downfall of Númenor, and the abandoned ‘time-travel’ story The Lost Road.
