_Alterius Orbis Papa_ (Vol. ii., p. 497.).--In Twysden's _Historical
Vindication of the Church of England_, p. 22. (Cambridge edition, 1847),
I find--
"After the erection of Canterbury into an archbishopric, the bishops
of that see were held _quasi alterius orbis papae_, as Urban II. styled
them."
In a note, William of Malmesbury (_De Gestis Pontif._, lib. i. in
Anselm., p. 223. l. 33.) is referred to as authority for the above
statement. Urban II. was pope from 1087 to 1099.
