The Merchant of Venice


Classifying The Merchant of Venice: The Merchant of Venice is a troublesome play to classify in the usual Shakespearean categories of comedy, history, or tragedy. Though it ends with several marriages, and therefore matches the usual pattern of a comedy, it also contains some very dark and problematic elements, such as Shylock’s essentially forced conversion to Christianity. How do you think that we should view this play? Is it really a comedy? Is there any way to argue that it is a tragedy? Be sure to clearly define your understanding of tragedy and comedy; for some helpful sites, see Comedy and Tragedy by David L. Simpson of DePaul University, and the Comedy and Tragedy pages by Lisa Schnell of the University of Vermont.
Essay completion guidelines:
The essay should be 500-750 words in length
It should be submitted by 11:55 pm ET on Sunday of Week 6
