THE FRANKISH STATE AND CHARLEMAGNE 197 nimself pleaded with him in vain to grant easier terms and to relinquish some of his conquests. Aistulf was not so easily (moved as Liutprand, who had more than once stayed his jattack at the pope's personal intervention. The pope thereupon crossed the Alps to complain in jperson to King Pepin, who came to meet him and walked by his side leading his horse by the bridle.

About this time, however, there came into existence a document called the Donation of Constantine. This spurious deed was based upon a legend, also without historical foundation, that Constan-
