  The completed critical edition of just one redaction of Marchia’s Sentences commentary will take up about a dozen volumes. It is roughly equal in size to that of his contemporary and confrère Landulph Caracciolo. Whereas Caracciolo’s commentary is frequently a disjointed, point-by-point refutation of Peter Auriol and defense of Scotus on many issues, however, Marchia was more selective in choosing his topics, more independent in giving his determination, and generally more eloquent. For example, Marchia asks only one brief question on the Immaculate Conception, a favorite Franciscan topic (book III, q. 8; Duba 2004), showing himself to support the immaculatist position, but he asks a great number of questions in books I, II, and IV on the relationship between the will and intellect.
