In Hagiography and Episcopal Authority in Medieval Iceland, Davide Salmoiraghi studies how Saints' sagas served to promote Gregorian ideals of ecclesiastical independence in the thirteenth-century Icelandic Church. The monograph focuses on the Nordic reception of St Ambrose of Milan (374-397), the most renowned militant bishop in the battle between regnum and sacerdotium, showing how the Old Norse version of his hagiography (Ambrósíuss saga biskups) influenced the sagas of those bishops who fought to free the Icelandic Church from secular control.
