While the genre of some works of literature can be debated, Macbeth written by William Shakespeare seems to fit into a perfect mold. Aristotleâs definition of a tragedy, combining seven elements that he believes make the genre of a work a tragedy, is that mold. Displaying all seven aspects, Macbeth fits the definition precisely. Key elements in the play substantiate the fact that Macbeth is a serious story, the first elements of Aristotleâs definition.
The tragedy was refined by Greek playwrights (Thespis, sixth century B.C., being the first) and subsequently the philosopher Aristotle (384-322 B.C.) into the most celebrated of dramatic genres: a play that treats, at the most uncompromising level, human suffering.
