William Shakespeare was a writer living on the turn of the 14th and 15th century, a pre-eminent writer, poet, actor, and playwright. He is probably the most recognizable writer of the English-speaking world, and many citations from his plays are used in common language today.
Macbeth (written around 1606) is one of his most popular and most frequently performed plays. It tells a story of desire of power, succumbing to temptations, and crime, as well as punishment for the felons. It also contemplates insanity and gradual moral decay, a popular theme among Shakespeare’s plays.
