[Infinite metamorphosis: witches, spirits and apuntes in Havana]

This article offers an alternative reading of Hampa afro-cubana: los negros brujos, by the Cuban Fernando Ortiz y Fernandes, and discusses the need to make the different ideas expounded by the author more complex. For this reason, it disputes the interpretations of some commentators influenced by his work. The article suggests some clues with regard to what Ortiz y Fernandes understood as forces capable of acting and manifesting themselves in the "bodies" of persons affected by the activities of those accused of being involved with magical practices and objects. It examines the creation of witches - as described by Ortiz y Fernandes - as an epistemic phenomenon and discusses the arguments and the practices and knowledge required for this purpose.
