The volume contains the critical edition of the Expositio super Elementationem theologicam Procli (prop. 108-135) by the German Dominican Berthold of Moosburg. This portion of text (De diis), is devoted to the return of the creatures in the first cause. The edition offers a privileged insight into the theological and philosopical debates of Berthold's time thanks to a well-documented investigations into Berthold's sources. An introduction (p. IX-XVIII) points to the vivid doctrinal context of Berthold's text, particularly by reconstructing the role played by authorities nearer to Berthold's own time in influencing his thought. Berthold does not by explicit citation indicate the passages where in reality he can be found paraphrasing or excerting from his authorities. However, Berthold’s dependence for lengthy passages of his commentary on previous doctrinal summae is an important fact to be borne in mind when evaluating the combinations of more ancient authorities that are used to bolster particular arguments. The introduction studies in depth the role played by the English Franciscan Thomas of York in Berthold's Commentary on Proclus. The systematic investigation of the relationship between the text of the two authors shows that Berthold quotes more from Thomas of York than from his Dominican predecessors in the Teutonic Province (Albert the Great, Ulrich of Strasburg and Dietrich if Freiberg). In particular the conviction running through Thomas of York’s Sapientale that the writings attributed to “Hermes Trismegistus” contained a quasi-Christian insight into the highest truths also lies behind Berthold’s specific strategies in employing clusters of Hermetic citations in order to reinforce the argument of Proclus’ text.

Die Distinktionen 4-17 des ersten Buches des durandischen Sentenzenkommentars, die hier in kritischer Edition vorgelegt werden, behandeln die Trinitätslehre. Es werden insbesondere die göttlichen Hervorgänge, die Unterschiede zwischen den Personen und im Allgemeinen die Unterscheidungen hinsichtlich des Wesens, der Einfachheit und der Unveränderlichkeit Gottes behandelt. Die Distinktion 17 ist der Lehre der caritas gewidmet. Das Teilstück, das hier erstmals kritisch ediert ist, scheint lediglich in einer einzigen von der ‚dritten Redaktion‘ abweichenden Fassung zu existieren.

The Commentary on the Sentences of Durand of Saint-Pourçain in terms of its originality and its importance, with respect to the understanding of the philosophical and theological discourses, has a prominent position within the Sentences commentaries of the fourteenth century. Durand's Commentary is a unique document for many considerable debates concerning the importance and the formative role of the doctrine of Thomas Aquinas. The volume contains the critical edition of Book II, dd. 1-5. This portion of text is devoted to the doctrines of the creation and the angels. The critical edition (p. 3-250) offers for the first time to the scholarly world the text of Durand's Commentary on the Sentences in the first two versions (A and B). Moreover the edition points to the vivid doctrinal context of Durand's Commentary by giving a privileged insight into the theological and philosopical debates thanks to a well-documented investigations into Durand's sources. The filological introduction (p. 13*-115*) gives a glimpse into the editorial work of Durand and contributes to the study of the manuscript tradition of Durand's Commentary in its threefold version, with particular reference to the first two versions (A and B) of the second Book. The introduction shows that Durand worked continuously on the text of the Commentary. There is clearly a continuous text transition from the first redaction to the third one, which takes place throughout revisional stages of the second redaction. Hence the extant manuscripts of the second redaction can be considered snap-shots of the different phases of this movement.
