We have already pointed out in discussing the Cathedrals that one of the most characteristic features of the Gothic architecture was the marvelous ease with which it lent itself to the expression of national peculiarities. Norman Gothic is something quite distinct from German Gothic which arose in almost contiguous provinces, but so it is also from English Gothic; these two were very closely related in origin and undoubtedly the English Cathedrals owe much to the Norman influence so prevalent in England at the end of the Twelfth Century, and the beginning of the Thirteenth Century. Italian Gothic has the principal characteristic peculiarities of the architectural style which passes under the name developed to a remarkable degree, and yet its finished product is far distant from any of the three other national forms that have been mentioned, yet is not lacking in a similar interest. Spanish Gothic has an identity of its own that has always had a special appeal for the traveler. Any one who has ever visited the shores of the Baltic sea and has seen what was accomplished in such places as Stralsund, Greifswald, Lübeck, and others of the old Hansa towns, will appreciate still more the power of Gothic to lend itself to the feelings of the people and to the materials that they had at hand. Here in the distant North they were far away from any sources of the stone that would ordinarily be deemed absolutely {168} necessary for Gothic construction. How effectively they used brick for ecclesiastical edifices can only be realized by those who have seen the remains of the Gothic monuments of this portion of Europe. The distinguishing mark of all these different styles is the eminent opportunity for the expression of nationality which, they afford. It might be expected that since they were all Gothic, most of them would be little better than servile copies, or at best scarce more than good imitations of the great originals of the North of France. As a matter of fact, the assertion of national characteristics, far from destroying the effectiveness of Gothic, rather added new beauties to this style of architecture. This was true even occasionally when mistakes were made by architects and designers. As Ferguson has said in his History of Architecture, St. Stephen's at Vienna is full of architectural errors and yet the attractiveness of the Cathedral remains. It was a poet who designed it and something of his poetic soul gleams out of the material structure after the lapse of centuries.
