An ex-voto is a votive offering to invisible forces, mainly given in fulfilment of a vow after being healed. It often takes form in the mold of the wounded member, a print that has been directly in contact with the body of the helped. This cyanotype was made with a radiography of my sick lungs, and plants I found dead in an exploited forest. In this photograph, I link the wounded wilderness – the French call forests “Earth lungs” – with my wounded lungs. Since Magic involves using analogies to weave links between a representation and its object in order to affect it, what kind of magic system is invoked when we summon action with contact prints? I tied this photograph to the terrible arsons devastating Amazonia, and more recently Australia, echoing with the disastrous impacts of global changes on the fragile balance of Earth life.
