Echoes are sculptures made of light, ghostly appearances originating from the three-dimensional documentation of existing sculptures constructed with geological matter. Their structures emerged from the splicing of animal, vegetal and human representations, resulting in forms that resemble metamorphosed faces, geological fragments, cosmic bodies, composite phenomena. An abstract conception of the face as a biological and cultural interface of recognition and difference is being proposed here as an inversion of the anthropocentric imaginary, maintaining however the paradoxical fate of anthropomorphism as a plea for the bridging with everything that could be considered as non-human.
