Owing to the scarcity of parchment, these grants of absolution were made out on asses' skins; and it will be seen, that, in the great struggle, these instruments retained in a very eminent degree that quality of stubborn resistance which had cost them in their original state many a beating from the driver's staff. The greatest enthusiasm was kindled among rich and poor; year after year, thousands of pilgrims flocked hither from all Germany to offer their aid, without reward or recompense, to the building of the tower; and out of the farthest boundaries, even from Austria, came wagons loaded with building-materials, the gratuitous offerings of the pious. Rich legacies were left to the work, and many a cloister devoted a fourth part of its yearly revenues to the same object So much for asses' skins! Meanwhile the Devil was not idle. In the night-winds he and his legions would shriek and yell and rattle among the scaffolding and cranes in vain. In the latter part of the thirteenth century, he shook the structure with a frightful earthquake, which terrified all Alsatia, and, although whole streets were thrown down in Strasburg, yet the foundations of the _Wunderbau_, as the Germans love to call it, were not loosened, and no stone was moved from its place. A few years afterward, in 1289, he once more made use of his favorite element, and laid in ashes the market-place of Strasburg all around the minster. More fortunate than its great compeers, St. Paul's of London, and St. Peter's of Hamburg, it miraculously experienced but trifling damage. Well, the great Erwin died at last, when he had built the tower as high as the roof-ridge of the nave. His son succeeded him, finished the tower to the platform, when he, too, was gathered to his fathers in 1339. John Hültz followed as master; and finally his nephew, Hültz II., in 1439, finished the grand pyramid, fixed the colossal cross in its place, and crowned the whole with a gigantic statue of the Virgin. Thus, from the laying of the foundation-stone till all was completed, were one hundred and sixty years; yet throughout this time the work was never discontinued, and five successive generations labored upon its walls. But the wrath of the Arch-Enemy, as may well be believed, waxed greater as this prodigious structure gradually developed itself in all its lordliness and strength, and was not at all appeased at its triumphant completion. Ever since then he has visited its stately height with especial marks of his malice. The most furious tempests have raged about it, and more than sixty times has it been struck by lightning, and five times have earthquakes shaken its foundations. But in vain. "The Golden Legend" tells us how Lucifer and the Powers of the Air stormed about the spire, and how he cried,-- "Hasten! hasten! O ye spirits! From its station drag the ponderous Cross of iron that to mock us Is uplifted high in air!" and how the voices replied,--
