Maman Brigitte takes a close look at the unique persona of Brigitte, who is a blend of the goddesses Brigid of Ireland and Oya of Western Africa. This book engages with Vodou as a religion and outlines the circumstances surrounding Brigitte's emergence in Haiti during the slave trade, tracing her development into a prominent figure for both Haitian and Irish immigrants who experienced similar social and economic circumstances in the US state of Louisiana. Through research, fieldwork, and personal experience, the author uncovers the story of Brigitte in Haiti, Brigitte in Louisiana, and Brigitte today, a dark goddess in the contemporary world.
