On the performance of the absent body
The absent body performance is a mode of performance art that abandons the corporeal and ephemeral tradition, already over-rhetorized in the dominant artistic sphere. In the performance of the absent body, performativity - the establishment of senses, orders and hierarchies beyond representation - arises without the presence or activity of the body, perlocuting through images, objects or processes in which the spectacular staging of the body strikes, which it becomes particularly performative - especially from a museum art and mediated as "corporal" - in contexts with recent stories of genocide, forced disappearance and exodus.
