Rochester's secret has been revealed. In the previous chapter, Bertha was merely an apparition; in this one, she becomes fully flesh and blood. An insane, Creole woman, Bertha represents British fears of both foreigners and women. Part human, part beast, Bertha is Jane's double, representing all of her rage and anger over the loss of identity the marriage promises to bring. Unlike Jane, who submissively gives in to Rochester's demands, Bertha refuses to be controlled; a woman whose stature almost equals her husband's, she fights with him, showing a "virile" force that almost masters the athletic Rochester. Finally, she is roped to a chair, much as Jane almost was in the incident in the red-room. Post-colonialist critics, such as Gayatri Spivak, have argued that Bertha, the foreign woman, is sacrificed so that British Jane can achieve self-identity, and the novelist Jean Rhys has written a novel called The Wide Sargasso Sea that presents Bertha's life in Jamaica before her madness. Both of these women writers suggest Rochester's relationship with Bertha wasn't as innocent as he claims; as a colonialist, he was in Jamaica to make money and to overpower colonized women. In the nineteenth-century, men had almost complete legal power over women, and perhaps this lack of power contributed to Bertha's madness, just as it caused Jane's temporary insanity in the red-room. These critics remind the reader that Jane Eyre isn't merely a story critiquing the social injustices against women, but also exposing the brutality of colonialism. In the previous chapter, Jane had joked about leading a rebellion of the women in Rochester's imaginary seraglio; now she has almost become a member of that harem, but Bertha leads the resistance.
