The Emperor was for a time successful: Tortona was taken, Milan razed to the ground, her name apparently lost: greater obstacles had been overcome, and a fuller authority was now exercised than in the days of the Ottos or the Henrys. The glories of the first Frankish conqueror were triumphantly recalled, and Frederick was compared by his admirers to the hero whose canonization he had procured, and whom he strove in all things to imitate[195]. 'He was esteemed,' says one, 'second only to Charles in piety and justice.' 'We ordain this,' says a decree: 'Ut ad Caroli imitationem ius ecclesiarum statum reipublicæ et legum integritatem per totum imperium nostrum servaremus[196].' But the hold the name of Charles had on the minds of the people, and the way in which he had become, so to speak, an eponym of Empire, has better witnesses than grave documents. A rhyming poet sings[197]:-- 'Quanta sit potentia vel laus Friderici Cum sit patens omnibus, non est opus dici; Qui rebelles lancea fodiens ultrici Repræsentat Karolum dextera victrici.' The diet at Roncaglia was a chorus of gratulations over the re-establishment of order by the destruction of the dens of unruly burghers. [Sidenote: Victory of the Lombard league.] This fair sky was soon clouded. From her quenchless ashes uprose Milan; Cremona, scorning old jealousies, helped to rebuild what she had destroyed, and the confederates, committed to an all but hopeless strife, clung faithfully together till on the field of Legnano the Empire's banner went down before the carroccio[198] of the free city. Times were changed since Aistulf and Desiderius trembled at the distant tramp of the Frankish hosts. A new nation had arisen, slowly reared through suffering into strength, now at last by heroic deeds conscious of itself. The power of Charles had overleaped boundaries of nature and language that were too strong for his successor, and that grew henceforth ever firmer, till they made the Empire itself a delusive name. Frederick, though harsh in war, and now balked of his most cherished hopes, could honestly accept a state of things it was beyond his power to change: he signed cheerfully and kept dutifully the peace of Constance, which left him little but a titular supremacy over the Lombard towns. [Sidenote: Frederick as German king.] At home no Emperor since Henry III had been so much respected and so generally prosperous. Uniting in his person the Saxon and Swabian families, he healed the long feud of Welf and Waiblingen: his prelates were faithful to him, even against Rome: no turbulent rebel disturbed the public peace. Germany was proud of a hero who maintained her dignity so well abroad, and he crowned a glorious life with a happy death, leading the van of Christian chivalry against the Mussulman. Frederick, the greatest of the Crusaders, is the noblest type of mediæval character in many of its shadows, in all its lights. [Sidenote: The German cities.]
