摘要:There are thematic and structural parallels between William Shakespeare’s Macbeth and John Milton’s Paradise Lost. The sub-plot of Paradise Lost focuses on Satan’s ambition to defeat Christ in order to regain his former position in Paradise, and the theme of Macbeth focuses on Macbeth’s ambition to be king of Scotland. William Shakespeare encapsulates the whole idea of this study through the opening line of Macbeth: (Fair is foul, and foul is fair). This essential line can be applied to both Satan and Macbeth.
