His views were noble and generous. It was his idea that there should be an annual meeting of the bishops to regulate the interests of the Church. A christian constitution, and above all a christian spirit, was to go forth from Germany, as from Judea in other times, and spread through the whole world. Charles V. was to be the youthful hero appointed to realize this golden age; but Hütten, having seen the failure of his hopes in this quarter, had turned towards Sickingen, and sought from knighthood what the empire had refused him. Sickingen, at the head of the feudal nobility, had played a distinguished part in Germany; but the princes had besieged him in his castle of Landstein, and the new invention of cannons had crushed those aged walls, accustomed to other attacks.[558] The taking of Landstein had proved the final defeat of chivalry,--the decisive victory of artillery over shields and lances,--the triumph of modern times over the middle ages. Thus the last exploit of the knights was destined to be in favour of the Reformation; the first effort of these new arms and system of warfare was to be against it. The mailed warriors that fell beneath the unlooked for storm of balls, and lay among the ruins of Landstein, gave way to other soldiers. Other conflicts were about to begin; a spiritual chivalry succeeded to that of the Du Guesclins and Bayards. And those old and ruined battlements, those battered walls, these dying heroes, proclaimed with greater energy than even Luther could have done, that not by such allies or such arms would the Gospel of the Prince of peace obtain the victory.
