Siger of Brabant, author of the anonymous Questio de creatione ex nihilo

An anonymous question on creation, in which a creatio ex nihilo is denied, has been preserved in only one manuscript of Paris. In the study Sigeri di Brabante. Questio de creatione ex nihilo (ms. Paris BnF lat. 16297, f. 116rb-vb): Edizione, paternità e cronologia, the editor Andrea Aiello edits this question and establishes the chronology and the authorship. This treatise is attributed to Siger of Brabant and is probably written between 1270 and 1277. This paper presents a review of this recently published study. It wants to demonstrate some methodological problems, but above all it is accentuated that this study will contribute greatly to scholarship on Siger of Brabant.
