Are these good ideas for an essay on Gothic literature? The man vs. the monster in Frankenstein, a psychoanalytical reading of The Raven, or analyzing Burke's text on the sublime to discuss Gothic architecture.
Since others have already made good points about the first topic, I'll champion the third. What, exactly, is Gothic architecture and how, precisely, does it contribute to the effects and effectiveness of Gothic literature? This is a fascinating question. It might be harder to research than the first question, but it might ultimately yield a more original paper.
As a fan of Frankenstein, I would agree that the first essay sounds the best. That being said, this is a topic which has been circulating and debated for many years. You would have plenty of research material if going this route, but I would be sure to try and present a different angle on the argument (in order to present something new).
I agree with #2. You will also have scope to bring inother texts within the genre to support your thesis - Dr Jekyll and Mr Hyde springs to mind, as does Bram Stoker's Dracula. Good luck with your writing!
I think that the first topic would be the easiest one in which to include discussion of the elements of Gothic Literature. In your effort to prove your thesis (who is the man and who is the monster) you would also be able to discuss literary elements such as the importance of setting, the atmosphere of fear, the sense of mystery and suspense, the emotional intensity of the characters, and any other characteristics that you have studied.
