Research project
My research argues that the Timaeus has been one of the major authorities used from Pre-Reformation until Counter-Reformation to either support or condemn the radical views of Western Christianity. One of the crucial topics discussed in these contexts was the perfect intelligible world created by the demiurge as model for the sensible world (Tim. 29c-31a). The doctrine of mundus archetypus, the world of ideas, describes the perfect world that enables the constitution of metaphysical and epistemological dialectic between the sensible and the intelligible.
Within my research I intend to make accessible a previously ignored cultural patrimony by editing hitherto unpublished texts. Based on these critical editions, I will address a major gap in scholarship by examining the reception of the Timaeus in the Latin West between the famous and well-studied School of Chartres and the Italian Renaissance. The main goal of my project is to provide the first-ever doctrinal study of the use of the Timaeus in two major moments of the Western thought: the beginning of the Reformation (from John Wyclif to Jan Hus) and Counter-Reformation. This project revisits a seminal hermeneutical concept in history of philosophy: Plato Christianus.
Three major sections articulate my PhD project: (i) an introduction to the reception of the doctrine of mundus archetypus in the Latin West (12th-13th-c.); (ii) a study with critical editions of the reading of the Timaeus in 14th-15th-c. in Pre-Reformation, from John Wyclif to Jan Hus; (iii) a study with partial critical editions from commentaries on the Timaeus from the 15th-16th-c., during the Reformation and Counter-Reformation.
