Commentaries on the Ars Vetus, by Walter Burley, 15th century

Identifier: MS 135// ff. 3r-87v; 89r-98v; 116r-118v


ff. ff. 3r-87v; 89r-98v; 116r-118v of MS 135 appear to be a version of a set of medieval commentaries on Aristotle's logic, by the 14th-century logician Walter Burley. Burley produced many commentaries, and multiple versions of his commentaries and other works, and the short commentaries found in MS 135, Isagoge, Predicamenta, Liber sex principiorum, Perihermeneias are from a collection produced in the later part of Burley's career, in a work titled Expositio super Artem Veterem Porphyrii et Aristotelis. Generally, these commentaries on the 'Ars Vetus' by Burley were well-known and popular for students of medieval logic up until the 16th century, with many surviving manuscript versions and editions.
