The article is a review of an academic popularization book written by Natalia Gabayet González, which explores the construction of the notion of personhood in the cultural creation of the black communities of the Costa Chica of Oaxaca and Guerrero, in Mexico. The book uses symbolic and ritual anthropology to analyze festivities, dances, and the importance of shadow and nahualism in the lives of these communities. It also criticizes the notion of "traces of Africanity" and highlights the importance of the devil's dance as an iconic element of Afro-descendant culture. The book raises questions about the centrality of childhood in Afro-descendant life, the impact of migration on Afro-descendant ontology, and the relationship between secrecy and anthropology.
