Il filosofo, il poeta e l’arcivescovo. Qualche precisazione sulla fine di Sigieri di Brabante

By reconsidering all the available sources (from Simon du Val’s inquisitorial summons of November 1276 to the Continuatio brabantina, from the Fiore to the X canto of Dante’s Paradiso, from William of Tocco to Peckham’s letters) the article calls into question the thesis – still widely shared – according to which Siger of Brabant died in Italy, and more precisely in Orvieto, at the Papal Court, before November 1284. Above all, from a doctrinal point of view, it shows how it is completely implausible that Peckham could refer to Siger of Brabant when, in his letter to the University of Oxford of November 10, 1284, he mentions two Seculars as the main defenders or ‘inventors’ of the thesis of the uniqueness of the substantial form in the human compound. The end of Siger in Italy could thus be, for the most part, a ‘black legend’, like that of the poisoning of Thomas Aquinas on behalf of Charles of Anjou. The article closes by showing some possible implications, even of a methodological nature, of this different approach.
