On cathedrals and alchemy: some modern interpretations of medieval iconography by Esprit Gobineau de Montluisant

Abstract This article explores the theme of the alchemical interpretations of medieval iconography through the life and the writings of Esprit Gobineau de Montluisant ( c. 1590–between 1652 and 1665). This French alchemist and poet indeed composed a dissertation on some of the ornaments on the main facade of Notre-Dame de Paris, in which he asserted that the sculptures that adorn it conceal alchemical allusions. This curious thesis, written by a practitioner who was in contact with leading political figures of his time, such as the diplomat Léon Bouthilier (1608–52) or the marshal Abraham Fabert d’Esternay (1599–1662), did not emerge from nothing. It is part of an exegetical literature that combines alchemical theories, scriptural allegories, and a sense of heritage for Gothic monuments that were often in disrepair at the time. Far from being anecdotal, Gobineau’s treatise continued to be studied and read over the following centuries by alchemists, writers, art critics and even archaeologists. This influence, albeit discreet, justifies rediscovering his life and his dissertation. It also reminds us of the need to consider works linked to Western esotericism in the study of European cultural and scientific history.
