There was, then, a return to Catholicism. But the spirit of Italian Catholicism was still too classic, too antique. A huge, light church like St. Peter's at Rome was not sufficiently mysterious; it was, as Lamartine observed, fitted, when all dogmatic religion should have disappeared from Europe, to become the temple of humanity. In Italy it was with the pre-Raphaelite painters alone that the Romanticists felt themselves akin; in Spain they found a kindred spirit in Calderon, whose mysticism they soon set high above their earlier favourite, Shakespeare's, realism and liberal-mindedness. Even Heiberg ranks Calderon above Shakespeare. There is a regular cult of the Gothic in art. Men turn with renewed admiration to the great monuments of their native land, to that style begotten of the deep feeling and the superstitious terrors of northern barbarians--Frenchmen, however. Albert Dürer, genuinely German, popular, simple-minded, but above all (with his stags bearing crosses between their antlers, and all the rest of his symbolical fancies) mystic, was canonised by the German Romanticists; even with us, Oehlenschläger and his sister persisted in seeing more in Dürer than other people could see. The infection was so universal that even the poet of the Gulnares, Alis, and Gulhyndis imagined himself a devotee of mysticism. Men's hearts were certainly not agitated by the religious agonies and hopes of the old pious times; but the strangeness of the Gothic style, and the extravagance which betrays itself in its artistic symbolism, harmonised with the unnaturalness and restlessness of their morbid modern imaginations. It may be related, as not without significance, that when Oehlenschläger first came into the presence of the leaders of the Romantic School, in whom he had naïvely expected to find a set of eager, emaciated ascetics, he was somewhat taken aback by the sight of Friedrich Schlegel's "satirical fat face shining cheerfully at him." It was, however, in the course of the ardent struggle against the neo-classical tendency that Friedrich Schlegel rendered his one true, and also really great, service to science: he introduced the study of Sanscrit, and thereby opened up to Europeans an entirely new intellectual domain. He laid the foundation, first of one new linguistic science, the Indo-Oriental, which henceforth developed alongside of the Greco-Roman, and then of a second, namely, comparative philology.
