In literary works as in architecture, form follows function. There are clear differences among novels, epics, lyrics, and plays, and what the author wishes to say determines which genre works best. The Night of January 16th could only be written as a play; The Fountainhead could only be written as a novel; Anthem could only be written as a novella. Using the recent work by Frederick Turner, Epic: Form, Content, and History, the author attempts to demonstrate that Atlas Shrugged is an epic in the tradition of The Iliad, Moby Dick, and Lord of the Rings.
