was that it practically annulled the papal interdict so far as the knowledge of the vulgar was concerned: for so long as there were priests to officiate, a bishop to preside, and a Pope to bless and to curse, how should the uninstructed people know that their country was under any fatal ban? To make such a universal excommunication possible the whole priesthood must have been subject and faithful to the one sole authority in the Church. Unfortunately for the prestige of Gregory, Henry was much more successful in the following year in all his enterprises, and it was Rudolf, the friend and elected of the Pope, and not his adversary, who died after a battle which was not otherwise decisive. This event must have been a great blow and disappointment as well as an immediate and imminent danger. For some time, however, the ordinary course of life went on in Rome, and Gregory, by means of various negotiations, and also no doubt by reason of his own consciousness of the pressing need for a champion and supporter, made friends again with Robert Guiscard, exerting himself to settle the quarrels between him and his neighbours, and to win him thus by good offices to the papal side. To complete this renewal of friendship Gregory, though ailing, and amid all these tumults beginning to feel the weight of years, made a journey to Benevento, which belonged to the Holy See, and there met his former penitent and adversary, the brave and wily Norman. The interview between them took place in sight of a great crowd of the followers of both and the inhabitants of the whole region, assembled in mingled curiosity and reverence, to see so great a scene. The Norman, relieved of the excommunications under which he had lain for past offences, and endowed with the Pope's approval and blessing, swore fealty and obedience to Gregory, promising henceforward to be the champion of Holy Church, protecting her property and her servants, keeping her counsel and acknowledging her authority. "From this hour and for the future I will be faithful to the Holy Roman Church, and to the Apostolic See, and to you, my lord Gregory, the universal Pope. I will be your defender, and that of the Roman Church, aiding you according to my power to maintain, to occupy, and to defend the domains of St. Peter and his possessions, against all comers, reserving only the March of Fermo, of Salerno, and of Amalfi, concerning which no definite arrangement has yet been made." These last, and especially the town of Salerno, one of the cities _la piu bella e piu deliziosa_ of Italy, says old Muratori, had been recently taken by Guiscard from their Prince Gisolfo, a _protégé_ and friend of the Pope, who excepts them in the same cautious manner from the sanction given to Robert's other conquests. Gregory's act of investiture is altogether a very cautious document:
