A thoroughly revisionist treatment of Jan Huss, based on re-examination of the vernacular literature of the Hussites and their antagonists. Perett takes this literature seriously as to its origins, its messages, and its consequences. Vernacular writings - treatises and songs - were not, as one might infer from the term, from the ordinary people. Rather, they were works composed in the vernacular language, by clerics (academics), in order to inform and stir the populace. "The decision to bring theological argumentation to the people was revolutionary," writes Perett. And thus historic. Still, the decision had effects not anticipated or desired - polarization, division, violence, and historical confusion. This was the "cost of theology in the vernacular." A reader of Perett's work at this point in the twenty-first century cannot help reflecting on the despotic dangers of free-range public discourse. This reader, as a self-conscious public intellectual writing in the vernacular, logs her work as a cautionary tale.
