Exu is the most celebrated African god in the Afro-Atlantic world. His cult, however, is not homogeneous. It results from a long historical process of conflicts, exchanges, dialogues, negotiations, impositions and resistance between different cosmological systems that came into contact at the confluence of African, European and American cultures. This book aims to provide some points of view through which their cult in Brazil can be characterized, especially in Candomblé and Umbanda, the two best-known denominations among religions of African origin, and to analyze their appropriation by Christian denominations — first by Catholicism and, more recently, by neo-Pentecostalism. The book also features the Afro-Atlantic mythology of Exu, in which 183 myths of this deity are compiled, identified in academic and religious texts, as well as three annexes that bring the iconography, filmography and musicography of Exu.
