It is many years since I first read Jane Eyre; it remains one of my top three all-time favorite books.
The author gathered many writers and "experts" on the topic of Charlotte Bronte and how her real life impacted upon the story line of Jane Eyre.

While the subject is fascinating to me, I found many of the essays difficult to follow, and pedantically written. Overall, three essays stood out, one in which the author thought that Jane Eyre was a heathen and not a "Christian." Citing the fact that Charlotte used the topic of the moon and earth in many passages, and thus she worshiped earth more than Christ.

There were two cited essays, both of which thought that it was only after Rochester was crippled from the fire while trying to rescue Bertha, his crazy wife in the attic, that Jane was able to tame, and perhaps powerfully emasculate Rochester.

If you, like me, are enthralled with the book Jane Eyre, you might find this interesting to read. Be prepared to add lots of outdated words to your vocabulary.
