Willy Loman has been called a modern tragic hero

Willy Loman has been called a modern tragic hero because, among other things, he is a common man; he is not “highly renowned and prosperous” like the tragic heroes of traditional tragedies.

One of your sources might be used to explain a specific concept related to tragedies; the other two sources should be books or articles on the play.
