Although Mozart's training had so imbued him with the spirit of Italian music that its essence appeared to him as the essence of music itself, yet he transformed the elements which he had so absorbed with the whole force of his individuality. He did not consciously adopt them as national, neither did he oppose them from motives of patriotism, and seek to substitute a German style. His individuality joined issue with the elements of an art ready to hand in full development, and produced works of art which were genuinely Italian, and also genuinely Mozart. The fresh new life which had awakened in German poetry, and which first caused a consciousness of national existence to show itself in the realm of art, touched Mozart at a time when his musical education was already firmly grounded. He could therefore without self-contradiction continue along the trodden path, and carry on the development of the Italian opera as a settled form of art, which he had made his own in the truest sense. But the impulse of German art laid hold, as we shall see, of his innermost being, and gave him clear consciousness of his capabilities as a German artist. Granted that the German element of his nature--with which he could never dispense--remained latent and inactive while he appropriated Italian art as his own, yet all that he so took was treated as his own free property and turned to account with German thought and feeling. While thus the German school of music was partly founded, partly endued with new life by him, he brought Italian opera to a climax as far as its universal application was concerned; after Mozart it becomes more exclusively national. Like every genius who has made his mark in the history of art, he casts his {IDOMENEO.} (146) glance over the past as well as into the future. To him it was given to concentrate the living elements of Italian music into works of mature perfection in art, and, setting to work with freshly tempered force, to turn to account the youthful impulses of German music, and lead them towards the goal of artistic freedom and beauty. Thus, in Idomeneo we recognise the genuinely Italian character of the opera seria, brought to its highest perfection by the force of Mozart's perfectly cultivated individuality; but in details we still perceive the ascendency of traditional form, to which the artist was obliged to yield.
