 Del Medigo’s physical and metaphysical works are the De primo motore, Quaestio de efficientia mundi, De esse et essentia et uno as well as his Annotationes in librum De phisico auditu super quibusdam dictis Commentatoris. These works were collected and printed during the sixteenth century (now available as a modern facsimile edition, see bibliography below). Another work by Del Medigo which concerns physical themes is his commentary on Averroes’ De substantia orbis. This work has survived in two manuscripts, a Latin autograph and a Hebrew translation of the Latin text, made by Del Medigo himself (a Hebrew-Latin bilingual critical edition of this work is currently under preparation).
