Character and the Supernatural in Shakespeare and Achebe [PDF ebook] 

Through mainly a New Historicist critical approach, this book explores how Shakespeare and Achebe employ supernatural devices such as prophecies, dreams, gods/goddesses, beliefs, and divinations to create complex characters. Even though these features indicate the preponderance of the belief in the supernatural by some people of the Elizabethan, Jacobean, and traditional Igbo societies, Shakespeare and Achebe primarily use the supernatural to represent the states of mind of their protagonists. Both writers appropriate supernatural features to mirror tragic flaws such as ambition, arrogance, impulsiveness, and fear that contribute to the downfall of Macbeth, Lear, Okonkwo, and Ezeulu. We relate to some of these characters because they project our inner minds, principal drives that may be hidden within us. Therefore, Shakespeare and Achebe’s preoccupation with the supernatural adds subtlety to their characterization and enhances their readability by situating their art beyond time, place, or particularity.
