The first of a two-book set that contains the early myths and legends which led to the writing of Tolkien's epic tale of war, The Silmarillion.

The Book of Lost Tales stands at the beginning of the entire conception of Middle-earth and Valinor for the Tales were the first form of the myths and legends that came to be called The Silmarillion. Embedded in English legend and English association, they are set in the narrative frame of a great westward voyage over the Ocean by a mariner named Eriol to the lonely Isle where the Elves dwelt; from them he learned their true history, the Lost Tales of Elfinesse. In the Tales are found the earliest accounts of Gods and Elves, Dwarves, Balrogs and Orcs; of the Silmarils and the Two Trees of Valinor; of the geography and cosmology of Tolkien's invented world.
