Berlioz has left in his Autobiography an extremely interesting account of the manner in which he composed it. Though he had had the plan of the work in his mind for many years, it was not until 1846 that he began the legend. During this year he was travelling on a concert-tour through Austria, Hungary, Bohemia, and Silesia, and the different numbers were written at intervals of leisure. He says:-- "I wrote when I could and where I could; in the coach, on the railroad, in steamboats, and even in towns, notwithstanding the various cares entailed by my concerts." He began with Faust's invocation to Nature, which was finished "in my old German post-chaise." The introduction was written in an inn at Passau, and at Vienna he finished up the Elbe scene, Mephistopheles' song, and the exquisite Sylph's ballet. As to the introduction of the Rákóczy march, his words deserve quoting in this connection, as they throw some light on the general character of the work. He says:-- "I have already mentioned my writing a march at Vienna, in one night, on the Hungarian air of Rákóczy. The extraordinary effect it produced at Pesth made me resolve to introduce it in Faust, by taking the liberty of placing my hero in Hungary at the opening of the act, and making him present at the march of a Hungarian army across the plain. A German critic considered it most extraordinary in me to have made Faust travel in such a place. I do not see why, and I should not have hesitated in the least to bring him in in any other direction if it would have benefited the piece. I had not bound myself to follow Goethe's plot, and the most eccentric travels may be attributed to such a personage as Faust without transgressing the bounds of possibility. Other German critics took up the same thesis, and attacked me with even greater violence about my modifications of Goethe's text and plot; just as though there were no other Faust but Goethe's, and as if it were possible to set the whole of such a poem to music without altering its arrangement. I was stupid enough to answer them in the preface to the 'Damnation of Faust.' I have often wondered why I was never reproached about the book of 'Romeo and Juliet,' which is not very like the immortal tragedy. No doubt because Shakspeare was not a German. Patriotism! Fetichism! Idiotcy!" One night when he had lost his way in Pesth he wrote the choral refrain of the "Ronde des Paysans" by the gaslight in a shop; and at Prague he arose in the middle of the night to write down the Angels' Chorus in Marguerite's apotheosis. At Breslau he wrote the Students' Latin Song, "Jam nox stellata velamina pandit;" and on his return to France he composed the grand trio in the work while visiting a friend near Rouen. He concludes:
