But how shall we parle concerning his voix? That exquisite organ, whose falsetto emulated the sweetness of flutes, and reached to A flat in altissimo—the voce media of which possessed an unequalled aplomb, whose deep double G must still find a well-in-tune echo in the tympanum of every amateur of taste. That, we must confess, as critics and theoretical musicians, causes us considerable embarras for words to describe. Who that heard it on Saturday last, has yet recovered the ravishing sensation produced by the thrilling tremour with which Rubini gave the Notte d’Orrore, in Rossini’s “Marino Faliero?” Who can forget the recitativo con andante et allegro, in the last scene of “La Sonnambula;” or the burst of anguish con expressivissimo, when accused of treason, while personating his favourite rôle in “Lucia di Lammermoor?” Ah! those who suffered themselves to be detained from the opera on Saturday last by mere illness, or other light causes, will, to translate a forcible expression in the “Inferno” of Dante, “go down with sorrow to the grave.” To them we say, Rubini est parti—gone!—he has sent forth his last ut—concluded his last re—his ultimate note has sounded—his last billet de banque is pocketed—he has, to use an emphatic and heart-stirring mot, “coupé son bâton!” It is due to the sentimens of the audience of Saturday, to notice the evident regret with which they received Rubini’s adieux; for, towards the close of the evening, the secret became known. Animated conversazioni resounded from almost every box during many of his most charming piano passages (and never will his sotto-voce be equalled)—the beaux esprits of the pit discussed his merits with audible goût; while the gallery and upper stalls remained in mute grief at the consciousness of that being the dernière fois they would ever be able to hear the sublime voce-di-testa of Italy’s prince of tenori. Although this retirement will make the present clôture of the opera one of the most memorable événemens in les annales de l’opéra, yet some remarks are demanded of us upon the other artistes. In “Marino Faliero,” Lablache came the Dodge with remarkable success. Madlle. Loewe, far from deserving her bas nom, was the height of perfection, and gave her celebrated scena in the last-named opera avec une force superbe. Persiani looked remarkably well, and wore a most becoming robe in the rôle of Amina. Of the danseuses we have hardly space to speak. Cerito exhibited the “poetry of motion” with her usual skill, particularly in a difficult pas with Albert. The ballet was “Le Diable Amoureux,” and the stage was watered between each act.
