Note 223 — Front matter (continued 3)
Reading edition
A good deal of controversy has been expended on the question whether Gregory did or did not threaten at this stage to depose Henry. Gregory's letter xxvi. (not in his Register, but of undoubted authenticity) to "the German People" expressly admits, or boasts, that he did. For further evidence see Dr. Martens, Gregor VII., i., 86-91.
