A Kimbundu-to-Portuguese dictionary from 1903 defines the related word nzumbi as soul, while a later Kimbundu–Portuguese dictionary defines it as being a “spirit that is supposed to wander the earth to torment the living”. One of the first books to expose Western culture to the concept of the voodoo zombie was W. B. Seabrook’s The Magic Island (1929), the account of a narrator who encounters voodoo cults in Haiti and their resurrected thralls.
