Macbeth introduces us to the savage and superstitious world of medieval, feudal Scotland. However, some of the themes that Shakespeare highlights are still relevant in the 21st century.
Themes are ideas that run all the way through a literary text. By analysing them you can better understand the writer's intentions. What choices have they made? Why? What are they trying to get the reader to think and feel? Analysing themes allows you to write in detail about a literary text.
In Macbeth there are many themes which could be analysed. Three main ones are:
ambition and power
the supernatural
appearances and reality
Shakespeare also investigated these themes in a number of other plays such as Julius Caesar, Hamlet, The Tempest and Othello.
