Note 403 — VIII The Pope and the Conquest of Ireland
Reading edition
The language must have been deliberately chosen, for the bishop’s letters and the Pope’s action are described in the same words:
“confirmantes ei et heredibus suis regnum Hiberniæ, et testimonium perhibentes ipsos eum et heredes suos sibi in reges et dominos constituisse imperpetuum” (p. 26). “summus pontifex auctoritate apostolica confirmavit ei et heredibus suis regnum illud, et eos imperpetuum reges constituit” (p. 28).
