Cardinal Reginald Pole (1500-1558) left an abundance of manuscripts that have lacked an inventory & description. This monograph is intended to remedy that lack & perhaps contribute to a critical edition of some of his major works, especially Pro ecclesiasticae unitatis defensione (De unitate),Ó Apologia ad Carolum QuintumÓ De summo pontifice,Ó De sacramento,Ó a more complete version of Discorso di pace,Ó &, the most difficult text, De reformatione ecclesia.Ó In order to grasp the importance of such a project, this volume provides a sketch of Pole's career & the significance of these works.
