The Quaestiones libri Physicorum by Franciscus Marbres (alias Johannes Canonicus). Part I: Author, Text and Reception

This article examines the author, date, place, sources and reception of the Quaestiones libri Physicorum by the Catalan Augustinian Canon Francesc Marbres, usually attributed to “John the Canon.” The Quaestiones are perhaps the most influential philosophical work by an Augustinian Canon in the university era. From Barcelona, Marbres became a Canon of Tortosa Cathedral, a Master of Arts at Toulouse, and an advanced student in theology, probably at Paris, where he died. In his Quaestiones, compiled around 1330, his main sources were works, primarily Sentential commentaries, by Franciscan theologians active at Paris from John Duns Scotus to Gerald Odonis. The Quaestiones survive in only two fourteenth- century manuscripts, described here, but at least 37 manuscripts (most of them complete) and eight printings from the fifteenth and sixteenth centuries attest to its later reception, which is traced down to the present day. Appended to the article is an annotated question- and citation-list. In part II of this study I shall describe the fifteenth- and sixteenth-century witnesses and investigate their tradition.
