Between the visible and the invisible Based on the texts and ethnographic notes written by anthropologist Paulo Valverde during his fieldwork in São Tomé and Príncipe between 1995 and 1999 and posthumously compiled in the book Máscara, Mato e Morte: Textos para uma etnografia de São Tomé, this photographic project seeks to capture and understand how, on these islands, the world of the dead coexists side by side with the world of the living. Working from a territory that is familiar to him, the author reflects on the theme of spirits, spectres, apparitions, belief, fiction and performance on the islands of São Tomé and Príncipe, taking photography as a means of representation of a spectral nature, which is positioned on a privileged plane of connection between the notions of life and death, of past and present, of the material and the intangible, belonging simultaneously to the realms of the invisible and of vision.
