This book proposes a new approach to Leonardo da Vinci’s Anatomical Corpus, both in ambition and in methodology. In dialogue with the extant research of Leonardo’s achievements and failures in terms of today’s scientific knowledge, it looks for the notion of the living body that is submerged in the labyrinthine, puzzling, little-explored complexes which are Leonardo’s folios. This book reads their configurations closely, in view of his thoughts on art, language, music, metaphysics, subjectivity, manhood, erotics. It thus discovers in them a unique weave of laughter, self-irony and apprehensions concerning the very science of subjecthood in the flesh.
