Susanna Clarke's excellent novel Jonathan Strange & Mr Norrell is written in a very convincing (at least to me) "19th-century literature" style. Not only the language used by the characters but also the sentence structure and storytelling style of the non-dialogue sections of the book feel very much like those of classical authors such as Austen, Hardy, or the Brontes.
Real connoisseurs of 19th-century literature will probably be shaking their heads at my lumping all of those authors together (so am I, to be honest). Hence my question: was there any specific classical author whose writing style inspired Clarke's style in Strange & Norrell?
Quotes from the author herself would probably be the best way of answering this, but if anyone can put together an answer based simply on textual analysis, I'll be mightily impressed.
