Ahhhhh the Bronte sisters are some of my favourite writers - Jane Eyre is the book that inspired my love for English 😍
The main concern with doing these would be they aren't exactly uncommon texts, so if you're going to do them they need to be done very well as the marker will have most likely read many dissertations on them in previous years/ perhaps even in the year they mark yours and therefore comparisons will be inevitable. It may be worth looking into The Tenant of Wildfell Hall by Anne Bronte, or Villette by Charlotte for a more unique twist. There is also Wide Sargasso Sea by Jean Rhys which is a novel from the perspective of Bertha Mason set while Rochester is in the colonies - although I believe that this and Jane Eyre is a fairly common pairing as well.
Themes that come to mind are:
- Romanticism (basically, love - as you said)
- deconstructing the Romanticism (everyone in Wuthering Heights is a pretty awful person, and the argument can certainly be made that Rochester is only so charming because Jane herself is narrating the story)
- A look at gender would also be possible, particularly how female characters are presented
- Love in the form of Obsession
- The Gothic
- The presence and importance of Nature
- Character development (Jane Eyre is a Bildungsroman after all
)
- Social Class
(these aren't mutually exclusive options btw, you could easily pick and match some together, or some could take smaller parts under the other - e.g an example title may be something like:
"A Literary Study of The Transformative Impact of Love on the Character Development of Cathy Earnshaw and Jane Eyre in Wuthering Heights by Emily Bronte and Jane Eyre by Charlotte Bronte"
And within it, it could also touch on the Gothic elements, Nature imagery and Obsession etc.)
Hope that I helped 😅
