The Diccionario Lukumí-Español is a major editorial work on the lukumí language that has emerged in the Yoruba community of Cuba. This dictionary presents itself as a practical answer to the problem of knowledge’s transmission on an island where communism and clandestinity still reign supreme. Through the complex and protean iconography of the Santería, I was able to address the issues related to the notion of auctoriality in contents' creation. This work allowed me to familiarize myself with the fieldwork, its possibilities and its limits.
