Tolkien's Middle Earth grew not only from his experiences in World War I and studies as a professor of English language and literature at Oxford, but from his childhood hobby of constructed languages (conlangs). Tolkien argued in his essay "A Secret Vice" that "for perfect construction of an art-language it is found necessary to construct at least in outline a mythology" along with it. In other words, "your language construction will breed a mythology." Middle Earth sprang into being in part so that Tolkien could draw on a mature culture, history and mythology for his beloved conlangs. As a result, we have Bilbo, Frodo and Sam; Gandalf the Grey, and Arag♉orn who is Strider; the One Ring, the covetous Gollum; and a harrowing journey to Mount Doom.

Houghton published the first US editions of the trilogy from 1954-1956. This second US edition follows closely the second UK from Allen & Unwin of the previous year, which was heavily revised and corrected by the author. These books, marketed as the "Revised Edition" and including a new foreword by💜 Tolkien, were issued both as individual volumes (as here) and a slipcased set.
