Abstract

An unpublished Latin commentary, never mentioned in the secondary literature, is in Augbsburg, Staats- und Stadtbibliothek, 4° Cod 68 ff. 272va-278ra. The same hand copies the text of the Liber de causis , the interlinear glosses and the commentary. This is most likely the result of an oral teaching, as the author refers to a previous lectio. The article discusses the explicit quotations of Albert the Great, Thomas Aquinas and Proclus, and shows that the anonymous author offers an original hypothesis about the author of the Liber de causis, that he openly criticizes Thomas Aquinas’ theory of substantial forms, but he often uses Thomas to quote Proclus
