I read that some while ago in its original language. Dictionary comes useful, as apparently the English of the day had, among other things, specific words for side entrances of castles and so on!
I didn't find it quite as bad as I expected, but it's certainly a bit difficult to follow. Anyhow, I feel the article, while being a good bit of literature history, kind of fails to bring up the moral teachings often found in many gothic and gothic horror stories. The quest for overcoming death, either through vampirism (
Dracula), witchcraft (
Wake Not The Dead), mad science (
Frankenstein) or a heir (
The Castle of Otranto), and the punishment for trying to act like a god, is perhaps the most common theme found. In a way, I see many gothic stories as lessons in humility. It was quite important in that era for stories to contain a moral teaching, even if a thinly veiled one.
