“Rienzi” was produced on Oct. 20, 1842, with the following cast: Rienzi, Tichatschek; Irene, Frl. Wüst; Stefano, Dettmer; Adriano, Mme. Schroeder-Devrient; Paolo, Wachter; Raimondo, Rheinhold; Baroncelli, Vestri; Cecco, Risse; Messenger, Frl. Thiele. The opera achieved an immediate and emphatic success, which fifty years of popularity have approved. “Der Fliegende Holländer” was now hurried upon the stage, and produced at Dresden, Jan. 2, 1843, with Schroeder-Devrient as Senta, and Mitterwurzer as Vanderdecken. The great change in style from “Rienzi,” the sombreness of the story, the simplicity of the action, and the originality of the music surprised and disappointed the public. Only Spohr seemed to perceive its real value. He said, “Among composers for the stage _pro tem._, Wagner is the most gifted.” Spohr produced the “Holländer” at Cassel on June 5, 1843, and was to the end an admirer of Wagner. Immediately after finishing this work in Paris, Wagner cast about for new material. He read a new version of the story of “Tannhäuser,” which set him to work to trace to its source the connection of this tale with that of the Wartburg song contest. Thus he came to read “Der Wartburgkrieg,” which introduces the story of “Lohengrin,” and Wolfram von Eschenbach’s “Parzival”; “and thus,” as he says, “an entirely new world of poetical matter suddenly opened before me.” Before the rehearsals of “Rienzi” he began the book of “Tannhäuser.” He completed the opera (though he afterwards made some changes) on April 13, 1844. In the mean time (January, 1843) he was made court conductor at Dresden, where he served seven years, producing the masterpieces of Gluck, Mozart, Weber, Mendelssohn, Beethoven, Spontini, and even Palestrina in the most artistic manner. He produced “Tannhäuser” at Dresden, Oct. 19, 1845, with Tichatschek in the title rôle; Schroeder-Devrient as Venus; his niece, Johanna Wagner, as Elizabeth; and Mitterwurzer, as Wolfram. The work pleased neither the public nor the critics. The music, except the simple broad march and chorus of Act. II., was pronounced ugly. Even the mellifluous “Evening Star” song was disliked; Tannhäuser’s dramatic story of his pilgrimage was called “a pointless and empty recitation,” and Wagner was blamed for not marrying his hero and heroine. Even Spohr, though he saw much that was “new and beautiful,” was troubled. Schumann alone declared of the work: “It contains deeper, more original, and altogether an hundred-fold better things than his previous operas; at the same time, a good deal that is musically trivial.” Wagner was discouraged, but instead of losing faith in his ideals, he decided on a course of literary propagandism: “to induce the public to understand and participate in my aims as an artist.” From this resolve sprang his subsequent theoretical writings: “Art and Revolution” (1849), “The Art Work of the Future” (1850), “Opera and Drama” (1851), etc. [Illustration: RICHARD WAGNER’S MOTHER.
