Even now I send you “Adelaide” with some timidity. You know what changes are wrought by a few years in an artist who is continually going forward; the greater the progress one makes in art the less one is satisfied with one’s older works. My most ardent wish will be fulfilled if my musical setting of your heavenly “Adelaide” does not wholly displease you, and if it should move you soon to write another poem of its kind, and you, not finding my request too immodest, should send it to me at once, I will put forth all my powers to do your beautiful poetry justice. Look upon the dedication as partly a token of the delight which the composition of your A. gave me, partly as an evidence of my gratitude and respect for the blessed pleasure which your poetry has always given, _and always will_ give me. Vienna, August 4th, 1800. When playing “Adelaide” sometimes recall your sincere admirer Beethoven. Whether or not Matthisson answered this letter is not known; but when he republished “Adelaide” in the first volume of his collected poems in 1815, he appended to it a note to this effect: “Several composers have vitalized this little lyric fantasy with music; but according to my strong conviction none of them so threw the text into the shade with his melody as the highly gifted Ludwig van Beethoven in Vienna.” The “Opferlied,” the words of which were also written by Matthisson, is one of the poems to which Beethoven repeatedly recurred. “It seems always to have presented itself to him as a prayer,” says Nottebohm. Its last words, “The beautiful to the good,” were written in autograph albums even in his later years. The origin of the composition is to be ascribed to 1795, as Nottebohm enters it in his catalogue. It was thus possible for Wegeler to know it in 1797, when he put a Masonic text under the music. It had not yet been published at that time, however, which fact accounts for the discovery of sketches for it in a sketchbook of 1798-1799 described by Nottebohm.
