Act One opens and closes with foreshadowing of Willy's fate. This is a literary technique used in other AQA Aspects of Tragedy texts.
The play's title and opening line (e.g. "I'm tired to the death") serve to foreshadowWilly's fate and create a tragic sense of inevitability.
Miller also ends Act One on a similar not of impending tragedy as the lights go down on Biff holding the rubber tubing which Willy is planning to use to kill himself.
This sense of inevitability- of a character unable to escape his/her fate- is also created in the other AQA Aspects of Tragedy texts.
For example,
Tess of the D'urbervilles:
Similarly, Tess of the D'urbervilles, Hardy's narrator explicitly states that Tess is used as "sport" by "the President of the immortals."
This recalls the tragic figures of classical tragedy who are brought down by the Gods.
Throughout the novel, Hardy's symbols often serve to foreshadow later events.
E.g. Tess' red ribbons forewarning readers of the bloodshed and passion to follow.
