The profusion of violent imagery provoked a question: how to distinguish the illegitimate violence that threatened and reversed the social order from the proper, “just,” and sanctioned use of force? Groebner constructs a persuasive answer to this question by investigating how uncannily familiar medieval dystopias were constructed and deconstructed. Showing how extreme violence threatens to disorient, and how the effect of horror resides in the depiction of minute details, Groebner offers an original model for understanding how descriptions of atrocities and of outrageous cruelty depended, in medieval times, on the variation of familiar narrative motifs.
