This deluxe manuscript preserves a rare, early, and unauthorized version (surviving in only 6 other copies) of an influential philosophical commentary on Aristotle. Produced only a generation after the death of the author, John Buridan, a celebrated fourteenth-century logician and philosopher, this volume is signed, dated, and even localized by its French scribe, Yvon Courtoys. Preserved in its original binding, this manuscript shines with elegant ivy-leaf and baguette decoration.
1. A scribal colophon dates and localizes this manuscript to Paris, 1395: “Iste questiones phisicorum sunt de tercio opere buridani et fuerunt scripte parisiis anno domini millesimo .ccc. nonagesimo quinto” (f. 46v). Since “parisiis” was added over an erasure, the manuscript may have been copied elsewhere (perhaps Brittany? see below) and then completed in Paris. The watermarks in the paper suggest a paper stock from Paris.
The scribe identifies himself in identical inscriptions at the ends of Books III and IV: “Deo gracias et fratri Yvoni Courtoys” (f. 7v, first column, and f. 15v, first column). In a third colophon at the end of the volume, he provides not only his name, but also that of his abbey: “[…] totius libri phisicorum per manus Yvonis Courtoys filii conventus sancti pauli in Leonia per eo orate cum diligencia” (f. 46v, second column). This is the Couvent des Carmes of Saint-Pol-de-Léon, in Brittany (France). The scribe is unrecorded in Bénédictins du Bouveret, 1973.
2. A fifteenth-century inscription “F. G. Zelini iste liber pertinent” (f. 50), appears to indicate monastic ownership, with the initial “F” likely standing for “Frater.”
3. Effaced inscription (completely illegible) beneath the colophon (f. 46v).

The Questiones super octo Physicorum libros Aristotelis – or Question-commentaries on Aristotle’s Eight Books on Physics – were composed by John Buridan (died c. 1361). There is an early print edition of these Question-commentaries (1509), as well as a modern critical edition of a selection of questions on Aristotle’s Physics (Pluta, 2002). A complete study and edition of the work is currently underway, with a new edition of Books I and II already published (Streijger and Bakker, 2015). Drawing on eleven manuscripts, this edition is based on the “second collection” or “ultima lectura” of Buridan’s Questiones super Physicorum, which survives in 32 manuscripts (see Thijssen’s list in Streijger and Bakker, 2015, p. XX and following).
Our manuscript, however, is part of an earlier redaction, known as the tertium opus in reference to Buridan’s third series of lectures on the Physics. The colophon corroborates this identification: “Iste questiones phisicorum sunt de tertio opera buridani…” (f. 46v). The present manuscript is one of only seven witnesses containing this earlier collection (see Thijssen in Streijger and Bakker, 2015, pp. XIII-XIV); three others (the Toulouse, Vatican and Zaragoza manuscripts, listed in Thijssen, in Streijger and Bakker, 2015, p. XIV) identify their contents as the tertium opus. Editors suggest that this rare version of the Question-commentaries derived from a first reportatio, or a written listener’s account. The later, more common version (the ultima lectura) likely reflects an ordinatio, a version authorized by Buridan himself.
John Buridan (or Buridanus) remains one of the most influential philosophers of the fourteenth century. He did much to shape philosophy not only during his own lifetime, but throughout the later scholastic and early modern periods. He spent his entire career as a teaching master in the arts faculty at the University of Paris, lecturing on logic and the works of Aristotle and producing many commentaries and independent treatises on logic, metaphysics, natural philosophy, and ethics. His most famous work is the Summulae de dialectica (Compendium of Dialectic), a text aimed at redeeming the older tradition of Aristotelian logic using the newer, logic of ‘moderns’ such as Peter of Spain and William of Ockham.
As in much of Buridan’s work, these Question-commentaries were produced for educational purposes and “were the material embodiment of oral teaching” (Thijssen, in Streijger and Bakker, 2015, p. XVIII). Most of Buridan’s works are commentaries on Aristotle. He wrote both expositiones (expositions or literal commentaries consisting of detailed, line-by-line explanations of the meaning of Aristotle's words) and quaestiones (longer, critical studies of the philosophical issues raised by Aristotle’s words, usually centered on a specific lemma from the text). Both genres originated in the classroom, a fact which becomes clear in the references to student queries and student concerns which survive in the written versions. Like teachers in our own day, Buridan lectured more than once on the same text over the course of his career, with the result that there are sometimes different versions of his commentary on the same work. For example, there are three versions of his Quaestiones on Aristotle's De anima, the last of which identifies itself as the “third or final lecture [tertia sive ultima lectura].” Where there are multiple versions of the same commentary, their relationship is generally one of increasing length and sophistication over time.
Buridan’s students and followers carried handwritten copies and early printed editions of his commentaries throughout Europe in order to use them as primary texts in university courses on logic and Aristotelian philosophy. In other words, masters would teach Aristotle by reading and explaining Buridan's commentaries to the class. These commentaries thus continued to shape European thought well into the Renaissance. Important because it is an early dated witness and because it preserves the relatively rare earlier version of Buridan’s Question-commentaries, this manuscript merits further study alongside the other witnesses to the tertium opus. Our knowledge of the book’s scribe and place of production also offer promising avenues for research into the circulation of this important philosophical work.
