The Portrayal of Women in Gothic Literature

Look at the portrayal of women in Gothic literature. What tropes do they often fulfil?

There’s the shrieking heroine of The Monk or The Italian (written by Matthew Lewis and Ann Radcliffe respectively). Even modern day Twilight has this.
Bram Stoker’s Dracula shifted things by having Mina as the ‘new’ woman – the only reason she was respected is because she supposedly had the brain of a man. Even then, she was viewed as someone who needed protecting.
Even texts like Jekyll and Hyde make a statement about women’s place in society by simply NOT including women in the narrative.
Modern Gothic texts tend to favour the cool and powerful female protagonist, which in theory seems empowering, but can also be problematic.

What is the effect of each portrayal of women? Are the women in each given text empowered or powerless? Is historical/social context important in how the female characters are portrayed? Do any texts defy their time period? Is there a difference between texts written by men and texts written by women?
An article on this should analyse a wide variation of texts, from different time periods.
