Dans une Espagne déchirée par la guerre de reconquête et l'Inquisition, trois hommes vont partir à la recherche de ce mystérieux ouvrage. Trois hommes que tout sépare : un juif, un moine franciscain et un Arabe. Ils n'auront pas d'autre choix que d'unir leur prodigieux savoir pour accéder à la plus grande révélation de tous les temps. Doña Manuela Vivero, proche d'Isabelle la Catholique, va croiser leur route. Elle est détentrice, affirme-t-elle, de la clé, l'ultime, celle qui conduit au Livre.
The city of Romans, in Dauphine province in S. France, was the annual scene of a colorfully animated Mardi gras carnival. In 1580, however, winter festivities degenerated into bloody ambush. While costumed craftsmen & peasants mimed & danced their uprising in the streets, & notables & bourgeoisie hurried from banquets to balls in ostentatious finery, Jean Serve-Paumier, master craftsman, draper & popular party leader was assassinated, his supporters beaten & pursued by a mob hired by Judge Antoine Guerin, leader of the inflexibly reactionary part of the ruling party. More than a cruel incident, this night marked the intersection of an urban movement & even larger rural stirrings. Ladurie marshals a wealth of evidence & reveals the town of Romans as a microcosm of the political & religious antagonisms tearing 16th-century France. Le Carnival de Romans: de la chandeleur au mercredi des cenders describes the massacre of about 20 artisans at an annual carnival. Ladurie uses the two surviving eyewitness accounts--one hostile towards the victims by Guérin, the other sympathetic yet often inaccurate by Piémond--along with such information as plague & tax lists, to treat the massacre as a microcosm of rural political, social & religious conflicts, thereby providing a good example of microhistory.
