Here the effort is made on presence. A absulte presence transcribed in the single drawing of a vertical line becoming the trace, the memory of this effort. Following the attempts to transcend death by creating permanent works, from the pyramids to E=MC2, this line becomes a sign that would be left in the future and that we could recognise in a hypothetical return. It is also a reflection on the value of life, whose completeness is affirmed in our self, seen here as the concentration of a single energy. This trace is perhaps also the one left in the sand by the cross that each of us must carry throughout our lives in Christian mythology. Above all it expresses the imperfection of every human being, whose actions are guided by impulses and emotions that overwhelm him and lead him to passion rather than reason. By adopting the format of the stele or the milestone, I'm trying to express through the simplicity of these works the fragility that makes our species so peculiar.
