I will explore the disturbance that has created in me the fortuitous appearance in my life of three other Hespel olive trees. I’m going to meet Olivier Hespel and Olivier Hespel who, like me, live in Brussels. The three of us will try to determine what distinguishes us and what unites us, and attempt a definition of the olive tree. We will then go to Corsica to join the fourth Olivier Hespel to take stock. This absurd quest will be an opportunity to unravel in images and sounds the many threads that weave the intimate and social link to our name, and also to translate the dizziness that provokes the questioning of this fundamental part of our identity that constitutes the last name.
