This book deals with the myths of the orishas. Since it was published in 1938 under the title Oh, M¡o Yemay !, it has become a classic in the field. It was the first attempt in Cuba to gather a sizeable sample of the numerous patak¡es or myths characteristic of the Regla de Ocha or Santer¡a, the most widespread of the Afro-Cuban religions practiced on the island. The author had to overcome prejudice that considered the religion and its associated literature undeserving of intellectual attention and at the same time penetrate the secrecy in which black believers cloaked their beliefs and practices, fearful with good reason of attracting disdain, desecration, and persecution.
