the papal procession streamed through the crowded gates, and reached the old palazzo appropriated for its lodging, there suddenly sprang up a well which had been greatly wanted in the place, a spring of fresh water henceforward and for ever known as the Fontana di Papa. These cities all joined the Tuscan league against the Germans with the exception of Pisa, always arrogant and self-willed, which stood for those same Germans perhaps because their rivals on every side were against them. It was at this period, some say, and that excellent authority Muratori among them, that the titles of Guelf and Ghibelline first came into common use, the party of the Pope being Guelf, and that of the empire Ghibelline--the one derived from the house of Este, which was descended from the old Teutonic race of Guelf on the female side, the other, Waiblingen, from that of Hohenstaufen, also descended by the female side from a traditionary German hero. It is curious that these distant ancestors should have been chosen as godfathers of a struggle with which they had nothing to do, and which arose so long after their time. [Illustration: PORTA MAGGIORE. _To face page 326._] Innocent, however, was not so good a Guelf as his party, for the Pope was the guardian and chief defender, during his troubled royal childhood, of Frederic of Sicily, afterwards the Emperor Frederic II., but at the beginning of Pope Innocent's reign a very helpless baby prince, fatherless, and soon, also, motherless, and surrounded by rapacious Germans, each man fighting for a scheme of his own, by which to transfer the insecure crown to his own head, or at least to rob it of both power and revenue. The Pope stood by his helpless ward with much steadfastness through the very brief years of his minority--for Frederic seems to have been a married man and ambitious autocrat at an age when ordinary boys are but beginning their studies--and had a large share eventually in his elevation to the imperial throne: notwithstanding that he belonged to the great house which had steadily opposed the claims of the Papacy for generations. It must be added, however, that the great enterprises of Innocent's first years could not have been taken up, or at least could not have been carried to so easy and summary a conclusion--whole countries recovered, the Emperor's nominees cast out, the cities leagued against their constant invaders and oppressors--had there been a fierce Emperor across _i monti_ ready to descend upon the always struggling, yet continually conquered, Italy. Henry VI., the son of Barbarossa, had died in the preceding year, 1198, in the flower of his age, leaving only the infant Frederic, heir to the kingdom of Sicily in right of his mother, behind him to succeed to his vast possessions. But the crown of Germany was, at least nominally, elective not hereditary; and notwithstanding that the Emperor had procured from his princes a
