The category dis/ability as research tool. Body norms in arts and aesthetics of the long 19th century

In my current research project I am investigating the theoretical, methodological and structural implications of the judgement of bodies deviating from norms in arts and aesthetics of the long 19th century. With the focus on corporeality, I am asking how norms can become fixed, but also how they can change. Using the category of dis/ability, the relationship between norm and deviation of corporeality is dynamized in a historical dimension.
