Abstract

This paper focuses on the exegetical proposal of the Tractatus de sex dierum operibus by Thierry of Chartres and it is tasked with analyzing the twofold interpretative framework adopted by the Cancelor: first, the accordance between the narration of Genesis and the heuristic models of physical and cosmological causality; second, the mathematical theology, which revises the work of creation according to an arithmological approach. The study is divided into two parts which follow the structure of the Tractatus. In the first part, I analyse the physical plausibility of Christian cosmogony and subsequently the conception of matter with regard to both William of Conches’ inordinatum and the hermetic locus mundi. In the second part, I examine how the numerical discourse interprets the creatural unfolding and dependence on God, as well as the creation per verbum and the individuality of each created being. My purpose is threefold: first, to test the inner philosophical coherence of the Tractatus; second, to interpret specific theoretical points at the light of Thierry’s commentaries on Boethius’ De Trinitate, and finally, to relate the arithmetical issues of the Tractatus to Thierry's Commentum super Arithmeticam Boethii.
