What is voodoo? To the outside world the word is usually associated with the black magic of sorcerers, werewolves and zombies; a mysterious cult of secret rites and sudden deaths. But Voodoo, with its African origins and Christian observances, is also a religion of “white magic”, with the emphasis on the comfort and support of its members. Based on his friendship with a Voodoo mambo [priestess] Metraux has written a sympathetic account of this religion in Haiti. Besides describing the actual ceremonies, the author introduces the gods and spirits who form the Voodoo pantheon, and discusses the relationship between Voodoo and the Church, magic and the darker aspects of this religion.
