 Rodulf also helped found the convent at Cahors where his sister Immena was installed as the first abbess.The earliest reference to the archbishop of Bourges as primate of Aquitaine dates from the episcopate of Rodulf.In 864, when Archbishop Sigebod of Narbonne complained to Pope Nicholas I that Rodulf had called some clergy of Narbonne before him "as if by patriarchal right" ("quasi jure patriarchatus"), the pope confirmed the right of clergy to appeal to Bourges if all avenues in Narbonne had been exhausted and of the suffragans of Narbonne to appeal to Bourges "as if to their patriarch" ("quasi ad patriarchum suum").
