We might read L’hermaphrodite: Sarrasine sculpteur by Michel Serres trying to imagine what it would be like if it was illustrated with some of Leonardo da Vinci’s drawings and paintings. There is a similarity between Serres’ thought and Leonardo’s iconic production, and it is based on the idea of enantiomorphism: a kind of morphogenesis among stones, animals, letters and bodies. The incarnato, the veil, the friction between surfaces and the inversion of the senses invite us to think about a theory of multiplicity that exalts the peculiarity of each single body. Either a gay science or a pataphysics.
