Neil Gaiman is a master of complex allegory, as shown by his Sandman comics. These books are designed to be an elaborate allegory for all human stories — “a story about stories,” as Gaiman puts it. At various points in the series, we see allegorical representations of various religions, historical figures, philosophical ideas, and even pop-culture icons. In the first book, a magician attempts to gain immortality by capturing Death in a magical cage – but he accidentally captures Death’s brother, Dream. Dream comes from a mystical realm in which legends and myths are real, and after his capture he struggles to get back to that realm before it falls into chaos. This is a complex allegory for the relationship between death, dreaming, and human mythology.
Longer essays may also contain an introductory page that defines words and phrases of the essay's topic. Most academic institutions require that all substantial facts, quotations, and other porting material in an essay be referenced in a bibliography or works cited page at the end of the text. This scholarly convention helps others (whether teachers or fellow scholars) to understand the basis of facts and quotations the author uses to support the essay's argument and helps readers evaluate to what extent the argument is supported by evidence, and to evaluate the quality of that evidence. The academic essay tests the student's ability to present their thoughts in an organized way and is designed to test their intellectual capabilities.
