This book tells the story of Marie Laveau, both mother and daughter of the same name. It's the story of an independent, black Creole woman who exercised cultural and social power, magical or otherwise, in the racially and culturally complex worlds of nineteenth century New Orleans.
New Orleans in the nineteenth century was a complicated place. Slaves, free blacks, French whites, southern whites, Creoles, "quadroons", and Native Americans seem to have moved through worlds with unique intersections in Catholicism, commercialism, inter-marriage, and the practical concubinage of "placage". Add to the mix the passage from French rule to American and you get an amazing mass of shifting racial, political, legal, and religious power relationships. And Laveau seems to have been as much a master of navigation through that complicated world as anyone could have been.
Voodoo rituals and beliefs certainly played a role in her power, and Voodoo certainly was "real" in the New Orleans of her time, in its beliefs and practices. You don't have to buy into a religious acceptance of Voodoo to appreciate it as a sociological force, especially within a population striving for the power to define and maintain itself in an often hostile culture.
Martha Ward's book, judging from what other readers have said of it, is probably not the definitive biography of Marie Laveau. But it is a very engaging account of the "story" of Marie Laveau, both mother and daughter. The author seems as much taken by what people believed of Laveau as what may actually have been true about her. She does take some pain to separate truth from myth, but the myth seems to have been an essential part of the history of Marie Laveau. Ward's sources, which include oral histories recorded via the WPA's Federal Writers' Project, provide just that same mix of fact and myth-like interpretation.
All in all, an entertaining book that I found intriguing enough to want to read more, more about the factual Marie Laveau and more about that fascinating tangle of politics, race, religion, and informal sources of power that made up the New Orleans of her time.
