Goethe found another source of inspiration in Strassburg besides Herder, and one which, as he describes it both in his Autobiography and in a contemporary effusion, moved him even more powerfully. His first act on his arrival in Strassburg, he tells us, was to visit its cathedral whose towers had caught his eye long before he reached the town. He had been taught by his old master Oeser, who only represented the general opinion of the time in Germany, that Gothic architecture was the product of a barbarous age and could be regarded only with amazed disgust by every person of educated taste. But Goethe's mystical studies and religious experiences in Frankfort had not left him what he was in his Leipzig days, and had given him an insight into movements of the human spirit which did not come within the cognizance of Oeser. It was with predisposed sympathy, therefore, that he looked for the first time on a specimen of Gothic architecture in its most august form. His first impression was of "a wholly peculiar kind"; and, without seeking to analyse the impression, "he surrendered himself to its silent working." Thenceforward, during his stay in Strassburg, the cathedral exercised a fascination upon him that evoked a new world of thought and feeling. It was his delight to ascend its tower at sunset and gaze on the rich landscape of Alsace, whose beauty made him bless the fate that had placed him for a time amid such surroundings. He studied its structure with such minute care that he correctly divined the additions to the great tower which the original architect had contemplated, but which he had been unable to carry out.
