The concept of the zombie is integral to Wide Sargasso Sea. In 'The Glittering Coronet of the Isles', the book that Rochester finds at Granbois, a zombie is an integral part of belief in obeah, and is 'a dead person who seems to be alive or a living person who is dead', a statement which bears similarities to Antoinette's belief in there being two deaths, the real, or spiritual, one, and the one 'everyone knows about': physical death. According to West Indian Voodoo, a dead person can be revived by a sorcerer, who will then give this zombie a new name. From that point on the zombie is enslaved to the sorcerer. When Rochester starts referring to Antoinette as Bertha she says 'that's obeah too'.
