Gregory the Great

Lady Morgan, in her letter to Cardinal Wiseman, speaks of "the pious and magnificent Matilda, Countess of Tuscany, the ally of Gregory *the Great*, and the foundress of his power through her wealth and munificence." By Gregory the Great it is evident that Lady Morgan means Hildebrand, or Gregory VII. May ask, through the medium of your pages, whether any authority can be found for terming Gregory VII. *the Great*, an epithet which I had previously considered to be confined to Gregory I.?
