Slave iron bit: The iron bit, also referred to as a gag, was used by slave masters and overseers as a form of punishment on slaves in the Southern United States.  The bit, sometimes depicted as the scold's bridle, uses similar mechanics to that of the common horse bit.  The scolds bridle however, is almost always associated with its use on women in the early 17th century and there are very few accounts of the device as a method of torture against black slaves under that particular name.  As opposed to the whip, the iron bit lacks the historic, social, and literary symbolic fame that would make information on the use of the iron bit as accessible.  Its use throughout history has warranted some attention though, mostly from literary texts.  Most notable is Toni Morrison’s novel "Beloved", which gives insight as to the emotional and mental trauma of being subjected to the bit.  Even earlier, slave narratives and publications of newspapers and magazines from the 18th century on give evidence of this device being used to torture and punish slaves.

African-American literature: African-American literature is the body of literature produced in the United States by writers of African descent.  It begins with the works of such late 18th-century writers as Phillis Wheatley.  Before the high point of slave narratives, African-American literature was dominated by autobiographical spiritual narratives.  The genre known as slave narratives in the 19th century were accounts by people who had generally escaped from slavery, about their journeys to freedom and ways they claimed their lives.  The Harlem Renaissance of the 1920s was a great period of flowering in literature and the arts, influenced both by writers who came North in the Great Migration and those who were immigrants from Jamaica and other Caribbean islands.  African-American writers have been recognized by the highest awards, including the Nobel Prize to Toni Morrison.  Among the themes and issues explored in this literature are the role of African Americans within the larger American society, African-American culture, racism, slavery, and social equality.  African-American writing has tended to incorporate oral forms, such as spirituals, sermons, gospel music, blues, or rap.

After 28 days of freedom, a posse arrives to retrieve her and her children under the Fugitive Slave Act of 1850, which gave slave owners the right to pursue slaves across state borders.  Sethe kills her two-year-old daughter rather than allow her to be recaptured and taken back to Sweet Home, the Kentucky plantation from which Sethe recently fled.  A woman presumed to be her daughter, called Beloved, returns years later to haunt Sethe's home at 124 Bluestone Road, Cincinnati, Ohio.  The story opens with an introduction to the ghost: "124 was spiteful.  Full of a baby's venom."
