Henry Edward Krehbiel,
A Book of Operas: Their Histories…
“ The lad's mind is, indeed, in a parlous state; he feels his body alternately burning and freezing; the mere sight of a maiden sends the blood to his cheeks, and he needs must sigh whenever he hears her voice; sleeping and waking, by lakeside, in the shadow of the woods, on the mountain, by stream and fountain, his thoughts are only of love and its sweet pains. It is quite impossible to describe the eloquence with which Mozart's music expresses the feverish unrest, the turmoil, and the longing which fill the lad's soul. ”
