Translations from the Elvish

Translations from the Elvish was a work, written in three volumes by Bilbo Baggins between T.A. 3001 and T.A. 3019, during his stay in Rivendell. They formed a substantial part of the Red Book of Westmarch, but were ommitted from other versions. They were preserved only in the Thain's Book and its copies.

Obviously it included such works as the Ainulindale and the Valaquenta and formed the basis for the collection of tales known as The Silmarillion.
