J.R.R. Tolkien may have created a vast fantasy world in which the footsteps of gods and monsters made its history tremble, but when it came down to the works he is best known for, The Hobbit and The Lord of the Rings, the choices that carried the most weight were ultimately made by some of the smallest people in it: hobbits.
Although Tolkien began his rich history, cosmology, languages, and geography of Middle-earth in the myths that would be published posthumously as The Silmarillion, he gave special attention when writing The Hobbit to a scene which could have been just one of many episodes in the story.
