[Letter from Pope Gregory I to Brunhild, queen of Austrasia and Burgundy]
Gregory grants concessions to a church and monastery and hospital founded by Brunhild, tells her he will send secret mandates by his legates, that he has found one bishop innocent and that another who is ill can be only temporarily replaced, and that a bigamist has not been permitted to take sacred orders.
