Resumen de Francesc Marbres, A.K.A. "Iohannes Canonicus"
The Quaestiones super Physica Aristotelis traditionally attributed to Iohannes Canonicus survive in over 35 manuscripts and at least 8 printings from 1475 to 1520. Yet historians have disagreed about the century (early 14th or mid-15th), the place of origin (England or Catalonia), the name (John Marbres or Peter Casuelis) and the institutional position (Franciscan or secular canon) of the author. This brief paper combines old and new evidence proving that the text was authored by an Augustinian Canon Regular of the Cathedral of Tortosa named Francesc Marbres, a Catalan from Barcelona, while he was Master of Arts at the University of Toulouse around 1330.
