The king [Frederick] advanced with his army to the neighborhood of Sutri and encamped in Campo Grasso. The pope, however, came to Nepi, and on the day after his arrival was met there by many of the German princes and a great concourse of clergy and laymen, and conducted with his bishops and cardinals to the tent of the king. But when the cardinals who came with the pope saw that the king did not come forward to act as the esquire of the pope [_i.e._, to hold his stirrup while he dismounted], they were greatly disturbed and terrified, and retreated to Civita Castellana, leaving the pope before the tent of the king. And the pope, distressed and uncertain what he should do, sadly dismounted and sat down on the seat which had been prepared for him. Then the king prostrated himself before the pope, kissing his feet and presenting himself for the kiss of peace. But the pope said: "You have refused to pay me the due and accustomed honor which your predecessors, the orthodox emperors, have always paid to my predecessors, the Roman popes, out of reverence for the apostles, Peter and Paul; therefore I will not give you the kiss of peace until you have made satisfaction." The king, however, replied that he was not under obligations to perform the service. The whole of the following day was spent in the discussion of this point, the army in the meantime remaining there. And after the testimony of the older princes had been taken, especially of those who had been present at the meeting of king Lothar and pope Innocent (II), and the ancient practice had been determined, the princes and the royal court decided that the king ought to act as the esquire of the pope and hold his stirrup, out of reverence for the apostles, Peter and Paul. On the next day the camp of the king was moved to the territory of Nepi, on the shores of lake Janula, and there king Frederick, in accordance with the decision of the princes, advanced to meet the pope, who was approaching by another way. And when the pope came within about a stone's throw from the emperor, the emperor dismounted and proceeded on foot to meet the pope, and there in the sight of his army he acted as the pope's esquire, holding his stirrup for him to dismount. Then the pope gave him the kiss of peace. 99. Treaty between Adrian IV and William of Sicily, 1156. Watterich, Pont. Rom. Vitæ, II, pp. 352 ff; Doeberl, IV, no. 34. By this document the long struggle between the popes and the kings of Sicily was brought to an end. The terms of the treaty were very favorable to the pope, but William retained as privileges certain things which were in other countries generally regarded as belonging to the pope. For the effects of this treaty on the relations between Adrian IV and Frederick I, see no. 100, introductory note.
