Bertha mason; JANE EYRE

Jane Eyre by charlotte  bront one of  the great work to english literature.Bertha mason is the protagonist of this novel, lived in jamaica as the daughter of very wealthy family. we get painful experience of her past  life not from her own perspectives; but from the hatred description of her unsatisfied husband, Edward Rochester .Bertha Mason: is she an abused wife, or just "the madwoman in the attic"?

Bertha’s family heritage is complex and puts her in a difficult position. She’s half-Creole and half-English, raised in Jamaica among the British aristocrat half of her family, and already not exactly a part of one world or the other.
She also suffers from congenital insanity . Rochester claims that she was drunken and promiscuous and that her excesses brought on her madness when she was young, but he’s not exactly an objective witness.It’s clear that she and Rochester never really got along and that they hadn’t gotten to know each other at all before they got married. In that sense, they were both screwed over by their families; they were young and silly, and neither of them really thought to slow down and thithey were young and silly, and neither of them really thought to slow down and think about things before saying their vows. As a result of all this, Bertha spends most of her adult life locked in a room—a few years in a room in Jamaica, and ten years in the attic at Thornfield. We don’t know about you, but we’d hate the person who did that to us, too.Bertha’s homicidal pyromaniac reaction, however, is admittedly a wee bit extreme. The fact that she crawls around on all fours making animalistic noises and laughing in a creepy way also suggests that the thread of her sanity has long since snapped. However, she’s still perceptive in some ways: she figures out that Rochester and Jane are going to get married, and she shows herself to Jane by destroying her wedding veil, trying, perhaps to warn her off gently, or at least signal to her that a marriage to Rochester isn’t going to work.
Oh, and she's also, um, kind of unkempt:
"And how were [Bertha's visage and features]?"
"Fearful and ghastly to me—oh, sir, I never saw a face like it! It was a discoloured face—it was a savage face. I wish I could forget the roll of the red eyes and the fearful blackened inflation of the lineaments!"
"Ghosts are usually pale, Jane."
Of course, Jane isn't just noting Bertha's (admittedly creepy) rolling bloodshot eyes and dramatically raised eyebrows. She's very problematically being terrified of Bertha's skin color, which is dark.

 Obviously, this has a lot of interesting implications for Bertha as a character, for Charlotte Brontë as an author, and for the "Autobiography" of Jane Eyre.

For Charlotte Brontë, Bertha seems to become a strange kind of alter-ego. Bertha is rejected by the man who was supposed to love her; Charlotte fell in love with an unattainable man (Constantin Heger). Bertha is kept prisoner in a lonely house on the English moors; Charlotte traveled a little, but spent most of her life shut up in her father’s house in Yorkshire, away from any big-city culture. Bertha is only able to show her powers to the world in what seem like insane, destructive ways; women novelists were common but their works were often considered ridiculous and their abilities inferior to those of men. The parallels are too strong to ignore, and perhaps Bertha does double-duty, both representing the restrictions that Charlotte felt and becoming Charlotte’s wish-fulfillment of breaking through those restrictions to inspire fear and awe.
 who narrates this entire novel and describes it as her "autobiography." Could Bertha represent Jane if she’s also Jane’s antagonist? Of course! We’re never more like someone than when we consider them our mortal enemy.
Think about it: Bertha is locked in a room for ten years and goes crazy "like some wild animal"; Jane is locked in the red room for five minutes and completely freaks out so that she’s "like a mad cat." Bertha sneaks around Thornfield at night to thwart Rochester’s plans of remarrying; Jane sneaks around Thornfield at night to thwart Rochester’s plans of using her to commit bigamy. Bertha’s supposed to be insane; Jane hears voices.
So here’s the thing: if Jane and Bertha are actually very similar, and if Bertha’s pyromaniac madness represents the incendiary potential of the woman writer telling her story, then it seems entirely possible that Jane could end up like Bertha, but that Jane just has the good fortune of being a little more desirable to Rochester and thus escapes Bertha’s fate.
