There is no slave after all like a wife

I choose this picture from the film "12 years a slave" because it shows the slave masters wife and his mistress. After reading Hearts of Darkness I thought it was ironic that the slaves masters wife would punish the mistress more cruelly for the transgressions of her husband. Omolade mentioned in her article that they were sisters in bondage. They were both taught to submit to the Husband/Master in all things. All  woman were slaves under patriarchy but the black woman was seen as someone with no human right to control her own body.
