George T. Ferris, Great Singers, Second Series
“ As a singer of romances Mario has never been equaled. He could not execute those splendid songs of the Rossinian school, in which the feeling of the theme is expressed in a dazzling parade of roulades and fioriture, the songs in which Rubini was matchless. But in those songs where music tells the story of passion in broad, intelligible, ardent phrases, and presents itself primarily as the vehicle of vehement emotion, Mario stood ahead of all others of his age, it may be said, indeed, of all within the memory of his age. ”
