  In no other period of the history of philosophy, as far as we know, have so many commentaries on works by Aristotle been written (both per year and in total) as in the  Renaissance.[5]   Even on the incomplete basis of Lohr’s first version of his catalogue of Renaissance Latin Aristotle  Commentaries[6]   Richard Blum has counted 6653 such commentaries for the period 1500 to  1650.[7]   The magnitude of this number should be considered significant—especially in comparison to the ca. 750 commentaries listed for the fifteenth century in Lohr’s catalogue of “mediaeval” Aristotle  commentaries.[8]
