You might like to examine a scene such as Act I scene 2 and focus on the literary devices that this scene contains. One of the notable examples of literary devices is the way that the Captain reports the deeds of Macbeth in battle and how he is compared to various things to emphasise his valour, bravery and skill in warfare. Note the following examples of similes:
Doubtful it stood;
As two spent swimmers, that do cling together
And choke their art.
Here the Captain describes the fight between the two sides and how close it was, comparing the armies to two exhausted swimmers who can not beat the other because of their fatigue. However, it is Macbeth, who enters "like Valour's minion" who wins the day and tips the balance of the battle.
These are some of the examples of literary devices in this scene, but there are plenty of others, so hopefully now that I have shown you what you are looking for you can go back and identify other examples of literary devices in Act I. Good luck!
Are there any others?
I was able to find a few in Act I scene i as well as scene ii.
Act I scene i:
"Fair is foul, and foul is fair" is an example of a chiasmus
"when the battles lost and won" forshadowing
"when the hurlyburly's done, when the battle is lost and won"- end ryhme
Act I scene ii;
"showed like a rebel's whore"- simille
there are ALOT of similies in scene ii, I'm sure you can find them!
Hope this helped!
