The Book of Lost Tales

The Book of Lost Tales is the title of a collection of early stories by J. R. R. Tolkien, and of the first two volumes of Christopher Tolkien's 12-volume series The History of Middle-earth, in which he presents and analyses the manuscripts of those stories, which were the earliest form of the complex fictional myths that would eventually comprise The Silmarillion. Each of the Tales is followed by notes and a detailed commentary by Christopher Tolkien.

Though they cover a broadly similar history, the Tales are very different from The Silmarillion. Firstly the Tales are more complex and detailed, written in an archaic style and include many obsolete words and phrases. Secondly, the interaction between the different elf-races is profoundly different from the Silmarillion: The exiled Noldoli (or "Gnomes", the Noldor of the later histories) suffer decisive defeat much earlier and become slaves of the enemy they had sought to punish. When Thingol feels disdain for Beren, it is because the latter is a gnome (not a mortal human) and therefore a thrall of Melko.

While many of the names in the book are identical or close to those in the later versions, some of them bear almost no resemblance to their final forms. J. R. R. Tolkien changed names rather frequently, sometimes with several new variants (rejected in turn) written in a single manuscript. Confusingly, sometimes the name applied to one thing is later used to refer to a different thing, the original use abandoned. As an example, the house of Elves called "Teleri" in The Book of Lost Tales is not the same as that in The Silmarillion (see Teleri). The original usage of "Teleri" would eventually change until the name became "Vanyar". Meanwhile, the house of Elves called "Solosimpi" would inherit the name "Teleri".

The framework for the book is that a mortal Man visits the Isle of Tol Eressëa where the Elves live. In the earlier versions of the "Lost Tales" this man is named Eriol, of some vague north European origin, but in later versions he becomes Ælfwine, an Englishman of the Middle-ages.

There are more changes visible within the book, and it is not internally consistent, partially because even while still writing it Tolkien began rewriting earlier parts as his ideas about the world changed. The Tales were eventually abandoned, but they were resurrected in part as the "Sketch of the Mythology" which would become the Silmarillion.

For publication the book was split into two volumes: The Book of Lost Tales 1 (1983) and The Book of Lost Tales 2 (1984), but this is simply an editorial division. Both volumes are separated into several "Lost Tales".
