supports: An epilogue or epilog ( from Greek  epílogos , `` conclusion '' from  - `` in addition '' and  légein , `` to say '' ) is a piece of writing at the end of a work of literature , usually used to bring closure to the work . It is presented from the perspective of within the story . When the author steps in and speaks indirectly to the reader , that is more properly considered an afterword . The opposite is a prologue -- a piece of writing at the beginning of a work of literature or drama , usually used to open the story and capture interest . Literature, in its broadest sense, is any single body of written works. More restrictively, it is writing considered as an art form, or any single writing deemed to have artistic or intellectual value, often due to deploying language in ways that differ from ordinary usage. Its Latin root "literatura"/"litteratura" (derived itself from "littera": "letter" or "handwriting") was used to refer to all written accounts, though contemporary definitions extend the term to include texts that are spoken or sung (oral literature). Literature can be classified according to whether it is fiction or non-fiction and whether it is poetry or prose; it can be further distinguished according to major forms such as the novel, short story or drama; and works are often categorized according to historical periods or their adherence to certain aesthetic features or expectations (genre). A prologue or prolog (Greek  "prólogos", from "pro", "before" and "lógos", "word") is an opening to a story that establishes the context and gives background details, often some earlier story that ties into the main one, and other miscellaneous information. The Ancient Greek "prólogos" included the modern meaning of "prologue", but was of wider significance, more like the meaning of preface. The importance, therefore, of the prologue in Greek drama was very great; it sometimes almost took the place of a romance, to which, or to an episode in which, the play itself succeeded. A preface or proem is an introduction to a book or other literary work written by the work's author. An introductory essay written by a different person is a "foreword" and precedes an author's preface. The preface often closes with acknowledgments of those who assisted in the literary work. An afterword is a literary device that is often found at the end of a piece of literature. It generally covers the story of how the book came into being, or of how the idea for the book was developed.
