In the third act the struggle between the nobles and the people advances another stage. The nobles have once more broken their oath, and are drawn up in battle array at the gates of Rome. Rienzi marshals his forces and prepares to march forth against them. In vain Adriano pleads once more for pardon. The fortune of war goes in favour of the plebeians. The nobles are routed, Colonna is slain, and the scene closes as Adriano vows vengeance over his father's body upon his murderer.

In the fourth act the tide has turned against Rienzi. The citizens suspect him of treachery to their cause. Adriano joins the ranks of malcontents, and does all in his power to fire them to vengeance. Rienzi appears, and is at once surrounded by the conspirators, but in a speech of noble patriotism he convinces them of their mistakes, and wins them once more to allegiance. Suddenly the doors of the Lateran Church are thrown open; the Papal Legate appears, and reads aloud the Bull of Rienzi's excommunication. Horror-stricken at the awful sentence, the Tribune's friends forsake him and fly, all save Irene, who, deaf to the wild entreaties of Adriano, clings to her brother in passionate devotion.

In the fifth act, Rienzi, after a last vain attempt to arouse the patriotism of the people, seeks refuge in the Capitol, which is fired by the enraged mob. The Tribune and Irene perish in the flames, together with Adriano, whose love for Irene proves stronger than death.

Wagner himself has described the frame of mind in which he began to work at 'Rienzi': "To do something grand, to write an opera for whose production only the most exceptional means should suffice...this is what resolved me to resume, and carry out with all my might, my former plan of 'Rienzi.' In the preparation of this text I took no thought for anything but the writing of an effective operatic libretto." In the light of this confession, it is best to look upon 'Rienzi' merely as a brilliant exercise in the Grand Opéra manner. Much of the music is showy and effective; there is a masculine vigour about the melodies, and the concerted pieces are skilfully treated, but, except to the student of Wagner's development, its intrinsic value is very small.

Appropriately enough, the idea of writing an opera upon the legend of the Flying Dutchman first occurred to Wagner during his passage from Riga to London in the year 1839. The voyage was long and stormy, and the tempestuous weather which he encountered, together with the fantastic tales which he heard from the lips of the sailors, made so deep an impression upon his mind, that he determined to make his experiences the groundwork of an opera dealing with the fortunes of the 'Wandering Jew of the Ocean.' When he was in Paris, the stress of poverty compelled him to treat the sketch, which he had made for a libretto, as a marketable asset. This he sold to a now forgotten composer named Dietsch, who wrote an opera upon the subject, which failed completely. The disappearance of this work left Wagner's hands free once more, and some years later he returned con amore to his original idea. 'Der Fliegende Holländer' was produced at Dresden in 1843.

The legend of the Flying Dutchman is, of course, an old one. The idea of the world-wearied wanderer driven from shore to shore in the vain search for peace and rest dates from Homer. Heine was the first to introduce the motive of the sinner's redemption through the love of a faithful woman, which was still further elaborated by Wagner, and really forms the basis of his drama. The opera opens in storm and tempest. The ship of Daland, a Norwegian mariner, has just cast anchor at a wild and rugged spot upon the coast not far from his own home, where his daughter Senta is awaiting him. He can do nothing but wait for fair weather, and goes below, leaving his steersman to keep watch. The lad drops asleep, singing of his home, and through the darkness the gloomy vessel of the Dutchman is seen approaching with its blood-red sails. The Dutchman anchors his ship close to the Norwegian barque, and steps ashore. Seven years have passed since he last set foot upon earth, and he comes once more in search of a true woman who will sacrifice herself for his salvation, for this alone can free him from the curse under which he suffers. But hope of mortal aid is dead within his breast. In wild and broken accents he tells of his passionate longing for death, and calls upon the Judgment Day to put an end to his pilgrimage. 'Annihilation be my lot,' he cries in his madness, and from the depths of the black vessel the weird crew echoes his despairing cry. Daland issues from his own vessel and gives the stranger a hearty greeting. The name of Senta arrests the Dutchman's attention, and after a short colloquy and a glimpse of the untold wealth which crams the coffers of the Dutchman, the old miser consents to give his daughter to the stranger. The wind meanwhile has shifted, and the two captains hasten their departure for the port.

In the second act we are at Daland's house. Mary, the old housekeeper, and a bevy of chattering girls are spinning by the fireside, while Senta, lost in gloomy reverie, sits apart gazing at a mysterious picture on the wall, the portrait of a pale man clad in black, the hero of the mysterious legend of the Flying Dutchman. The girls rally Senta upon her abstraction, and as a reply to their idle prattle she sings them the ballad of the doomed mariner. Throughout the song her enthusiasm has been waxing, and at its close, like one inspired, she cries aloud that she will be the woman to save him, that through her the accursed wretch shall find eternal peace. Erik, her betrothed lover, who enters to announce the approach of Daland, hears her wild words, and in vain reminds her of vows and promises made long ago. When Daland brings the Dutchman in, and Senta sees before her the hero of her romance, the living embodiment of the mysterious picture, she gazes spell-bound at the weird stranger, and seems scarcely to hear her father's hasty recommendation of the new suitor's pretensions. Left alone with the Dutchman, Senta rapturously vows her life to his salvation, and the scene ends with the plighting of their troth.

In the last act we are once more on the seashore. The Dutch and Norwegian vessels are moored side by side, but while the crew of the latter is feasting and making merry, the former is gloomy and silent as the grave. A troop of damsels runs on with baskets of food and wine; they join with the Norwegian sailors in calling upon the Dutchmen to come out and share their festivities, but not a sound proceeds from the phantom vessel. Suddenly the weird mariners appear upon the deck, and while blue flames hover upon the spars and masts of their fated vessel, they sing an uncanny song taunting their captain with his failure as a lover. The Norwegian sailors in terror hurry below, the girls beat a hasty retreat, and silence descends once more upon the two vessels. Senta issues from Daland's house, followed by Erik. In spite of his importunity, her steadfast purpose remains unmoved; but the Dutchman overhears Erik's passionate appeal and, believing Senta to be untrue to himself, rushes on board his ship and hastily puts out to sea. Senta's courage rises to the occasion. Though the Dutchman has cast her off, she remains true to her vows. She hastens to the edge of the cliff hard by, and with a wild cry hurls herself into the sea. Her solemn act of renunciation fulfils the promise of her lips. The gloomy vessel of the Dutchman, its mission accomplished, sinks into the waves, while the forms of Senta and the Dutchman transfigured with unearthly light are seen rising from the bosom of the ocean.

The music of 'Der Fliegende Holländer' may be looked at from two points of view. As a link in the chain of Wagner's artistic development, it is of the highest interest. In it we see the germs of those theories which were afterwards to effect so formidable a revolution in the world of opera. In 'Der Fliegende Holländer' Wagner first puts to the proof the Leit-Motiv, or guiding theme, the use of which forms, as it were, the base upon which the entire structure of his later works rests. In those early days he employed it with timidity, it is true, and with but a half-hearted appreciation of the poetical effect which it commands; but from that day forth each of his works shows a more complete command of its resources, and a subtler instinct as to its employment. The intrinsic musical interest of 'Der Fliegende Holländer' is unequal. Wagner had made great strides since the days of 'Rienzi,' but he had still a vast amount to unlearn. Side by side with passages of vital force and persuasive beauty there are dreary wastes of commonplace and the most arid conventionality. The strange mixture of styles which prevails in 'Der Fliegende Holländer' makes it in some ways even less satisfactory as a work of art than 'Rienzi,' which at any rate has the merit of homogeneity. Wagner is most happily inspired by the sea. The overture, as fresh and picturesque a piece of tone-painting as anything he ever wrote, is familiar to all concert-goers, and the opening of the first act is no less original. But perhaps the most striking part of the opera, certainly the most characteristic, is the opening of the third act, with its chain of choruses between the girls and the sailors. A great deal of 'Der Fliegende Holländer' might have been written by any operatic composer of the time, but this scene bears upon it the hall-mark of genius.

If 'Der Fliegende Holländer' proved that the descriptive side of Wagner's genius had developed more rapidly than the psychological, the balance was promptly re-established in 'Tannhäuser,' his next work. Much of the music is picturesque and effective, even in the lowest sense, but its strength lies in the extraordinary power which the composer displays of individualising his characters—a power of which in 'Der Fliegende Holländer' there was scarcely a suggestion.
