This article presents the research developed during the conception of the artistic work Ossuário (2015). The starting point of this investigation is the search for the composition of a ritual performance with animal bones, aimed at establishing an open liminal zone as a resonance field for the power of death. Initially, an understanding of the relation between performance and ritual is articulated, considering the concept of liminality, as well as an understanding of ancestry as a factor that underlies the artistic practice integrated in the research. Subsequently, the account of the creation process of the performance follows, consisting of immersions in the Sertão of the interior of Piauí and in the dunes of the coastline of Fortaleza, in northeastern Brazil, in order to discuss its conceptual and poetic elements.
