A history and geography teacher in Alsace, Sonia Pelletier-Gautier is mostly inspired by her university researches in medieval and regional history to outline a very accurate picture of the Germanic Roman Empire Society at the awakening of Rhenan humanism. Rich with archaeological and museum experiences, she also published a number of articles in newspapers and historical magazines, taking part, as well, in collective works, such as the dictionary of Alsacian biographies. On top of that, her thesis was awarded a prize by the “Conseil Général du Haut Rhin”, and published, warranted by the “Société Savante” of Eastern Regions. Mixing up Rhenan forgotten of famous actors with fiction but credible characters, she restores from the past the fear of inquisition to stimulate her contemporaries’ thinking about vanity of certainties at a time that could be theirs.
