Abstract

The author is a student of the renowned German medievalist, Josef Koch. Having himself worked for more than ten years on medieval commentaries on Aristotle's Physics and Metaphysics, Zimmermann wishes to make the result of his researches available to others. To reduce his mass of material to tractable dimensions, he follows the pattern of F. Stegmüller's Repertorium of commentaries on Lombard's Sentences, giving first a description of the manuscripts examined, then a transliteration of the titles of all questions treated in the respective commentaries, together with the folio at which each question begins, and grouping the works of identified authors before the anonymous works in each category. The first volume is limited to manuscripts contained in collections at Munich, Innsbruck, Cambridge, Oxford, London, Paris, and Cambrai; a second volume, with wider coverage, is promised shortly. The majority of the authors reported on in the first volume are anonymous, but those identified include Adam of Bocfeld, Augustine Triumphus of Ancona, Boethius of Dacia, Geoffrey of Aspall, John of Wacfeld, Peter of Alvernia, Radulfus Brito, Siger of Brabant, Simon of Faversham, William Bonkys, William of Chelvestun, and William of Clifford. This, like Stegmüller's, is clearly a reference work for scholars, and its principal merit lies in that it provides an accurate list of physical and metaphysical topics being discussed at centers of learning in England and on the Continent from the mid-thirteenth to the mid-fourteenth centuries. It was during this period, of course, that Aristotle was having his greatest impact on Latin Christendom. The questions listed by Zimmermann have their intrinsic interest, but even more they provide historians of science and of philosophy with considerable material for investigation, for analysis, and, hopefully, for the dating and identification of the works listed as anonymous. Zimmermann makes no attempt at completeness of reference, supplying only a few citations in his notes; on Geoffrey of Aspall, for instance, he refers only to Emden's Biographical Register, missing Enya MacRae's Geoffrey of Aspall's Commentaries on Aristotle, Medieval and Renaissance Studies 6. Regrettably the volume has neither a subject index nor a register of names, deficiencies that seriously impair its usefulness--W. A. W.
