by William Shakespeare
A short synopsis found on eNotes.com:
“On the level of human evil, Shakespeare’s Scottish tragedy is about Macbeth’s bloody rise to power, including the murder of the Scottish king, Duncan, and the guilt-ridden pathology of evil deeds generating still more evil deeds. As an integral part of this thematic web is the play’s most memorable character, Lady Macbeth. Like her husband, Lady Macbeth’s ambition for power leads her into an unnatural, phantasmagoric realm of witchcraft, insomnia and madness. But while Macbeth responds to the prophecies of the play’s famous trio of witches, Lady Macbeth goes even further by figuratively transforming herself into an unnatural, desexualized evil spirit. The current trend of critical opinion is toward an upward reevaluation of Lady Macbeth, who is said to be rehumanized by her insanity and her suicide. Much of this reappraisal of Lady Macbeth has taken place in discussions of her ironically strong marriage to Macbeth, a union that rests on loving bonds but undergoes disintegration as the tragedy unfolds.”
This is Shakespeare’s shortest play, written for the attention span of King James. It is loosely based on historical events.
Watch out for Act 3 Scene 5, it is believed that that scene was added at a later date and not written by Shakespeare. You can see that the lines are shorter, the very small part is almost superfluous to the surrounding plot, and it just doesn’t have the feel of the illustrious playwright.
