Medieval racialization marked non-Christian bodies through overlapping social categories. [causal]
Anxieties surrounding ethnicity and bodily differences were imprinted on non-Christian bodies, in particular, on Jews, Muslims, and Africans. This was a medieval kind of racialization, characterized by Cohen as "a phenomenon of multiple category overlap rather than a distinctly verifiable or measurable 'thing'. . . (that is, race has no independent ontology), and race is therefore always written on and produced through the body (race is nonetheless biological)." This medieval "multiple category overlap" echoes Foucault's argument that human bodies are determined by the "effects of power." Muslim monsters are punished bodies, often suffering with more than one disease or affliction.
