While reaching an outstanding complexity in the improvement of the human portrait, while exploring the perfection of the human body’s proportions and symmetries, Leonardo da Vinci sketches several experiments in deformation and exaggeration of the human figure.

Scholars refer to Leonardo’s deformations as proto-caricatures, because of their lack of explicit satirical aims. Indeed, Leonardo’s misshapen figures are entangled with his more general inquiry on the human subject, on the inherent shape, both physical and psychological, of the human individual. In this perspective, the caricature can be considered as the exploration of divergent possibilities of representation of humanness, and also a form of criticism against the canonization of the Renaissance portrait, that adopted idealized models screening off the observation of reality.
