Abstract

This article concerns two medieval codices kept at the library of the Istituto Campana in Osimo that contain commentaries on Aristotle. The focus of the paper is the identification of a new copy of Humbertus of Preuilly’s Sententia on the Metaphysics, transmitted in manuscript 18.M.11, and of a new copy of John of Jandun’s Questions on the Physics, transmitted in manuscript 18.L.38. In addition, information is provided on two texts transmitted anonymously in manuscript 18.L.38, namely Radulphus Brito’s Questions on Aristotle’s Meteorology and a commentary on the Physics by a Bolognese master of the first half of the fourteenth century.
