In Act IV, Scene I, Shakespeare is referring to a red letter day (any day of special significance) when Macbeth states, “… Let this pernicious hour stand aye accursed in the calendar!” (149 – 150).* Macbeth is referring to the news from the witches that tell him of eight kings descended from Banquo (instead of Macbeth.) The witches tell Macbeth many things that he cannot understand; yet, the witches are telling Macbeth the truth…
In Act III, Scene I of William Shakespeare’s "The Tragedy of Macbeth," Banquo tells Macbeth that he will ride as far as he can before supper. The word “twain” derives from the Old English word twegen, simply meaning “the number two (2).” Essentially, Banquo states that he will be riding in the dark an hour or two if his horse is slow. (Poets frequently use “twain” instead of “two” at the ends of lines for rhyming purposes.)
Composed probably in 1606, Shakespeare’s use of the word “epicure” in "Macbeth" is particularly interesting because at that time, “epicure” was considered “archaic” that is, rare in the early 1600s present-day usage. The meaning of Shakespeare’s “epicure” is taken from the philosophy of an ancient Greek philosopher, Epicurus (341–270 B.C.E.) An “epicure” is a person that disbelieves in God (the divine government of the world,) and in an afterlife spent in either Heaven or Hell; this is also a person who recognizes no religious motives for conduct.
Elizabethans didn’t bathe often, but the wealthy used a lot of perfumes, which they purchased from merchants who traded with Arabia. Arabia (included in the countries that now consist of what we call the Middle East) would have seemed exotic and faraway to Shakespeare’s audience.
In Act V, Scene XI of "Macbeth," Siward learns of his son’s death from Ross. Siward tells Ross and Maclcolm that he was glad that his son died the honorable death of a soldier saying: “And so his knell is knolled.” Shakespeare is using complex figurative language here to express reverence surrounding Malcolm’s son’s death.
“The Tragedy of Macbeth” (a.k.a. The Scottish Tragedy) is a story about one man’s guilt – a story about one man’s journey into madness. The real horror is what we don’t see. Try reading Macbeth in this light and perhaps you will have a keener understanding of the real horror which ideally should be in the reader’s imagination.
In Act IV, Scene III of Shakespeare’s “The Tragedy of Macbeth,” Malcolm tells Macduff that even someone who has morals and integrity may cave under the pressure of a demand from their king. Malcolm is referring to Lucifer (the Devil.) In most religious traditions, Lucifer is considered the most intelligent (the brightest as in genius) and the most outstanding (the brightest or best) of God’s angels. In addition, Malcolm is saying that Macbeth was once the brightest and best and now he acts a lot like Lucifer.
For the effect of sensationalism, William Shakespeare frequently used ghosts in his plays.
