Merlin, offspring of the Prince of Hell and of a pure virgin, has power over the demons, whom however he only employs in the service of Heaven, his good mother's spirit protecting him. Merlin calls up a demon, whom he forces to blind the heathen Saxons, so that the Britons may be victorious. The demon obeys unwillingly and after Merlin's departure he calls up the fairy Morgana who knows all the secrets of the world. Morgana tells the demon, that if Merlin loves an earthly woman, his power will be gone and the demon resolves to tempt Merlin with the most beautiful woman on earth. He vanishes and the Britons return victorious, Merlin with prophetic insight recognizing the knight, who had betrayed his people to the Saxons. While he sings a passionate chant in honor of his King and his country, Vivien, a Duke's daughter, appears and they are at once attracted to each other. But Merlin vanquishes his love and refuses to accept the crown of oak-leaves, which his King offers him by the hand of Vivien. Then Artus takes his own crown and puts it on Merlin's curls.

The second act begins with a conspiracy headed by Modred, Artus' nephew, against his uncle. Lancelot openly accuses him of treason, and the King sends to Merlin, for judgment. But alas, Merlin's love has already blinded his understanding; he fails to detect the culpable Modred, and declares that he is not able to find fault in him. King Artus and his knights depart to seek new laurels, leaving the country in Modred's hands. Merlin stays in his sanctum, to where the demon now leads Vivien who has lost her way. The doors of the temple open by themselves at Vivien's request, and she finds a rosy, glittering veil, which, thrown into the air, causes various charming apparitions to present themselves.—When Merlin comes, the whole charm vanishes into air. Vivien tells him of her delightful adventure, but Merlin, frightened, informs her that who ever is touched by the veil, will be in the power of demons, chained to a rock for ever. Love conquers, and the short hour succeeding is for both filled with earth's greatest bliss. The news of Modred's treachery to King Artus awakes Merlin from his dream. He tears himself from his love, vowing to shun her for ever and to return to the well of grace. But Vivien, finding all her prayers vain, throws the fatal veil over him to hinder his flight. The dreadful effect becomes instantly apparent; the rose-garden disappears, mighty rocks enclose the vale on all sides, and Merlin is held down by burning chains.

While Vivien is consumed by self-reproach and pain, the fairy Morgana appears, telling her that love, which is stronger than death, can bring Merlin eternal grace. Vivien is led away by her maid, and Lancelot enters with the knights to seek Merlin's help against the treacherous Modred.

Seeing Merlin in this pitiful state, he sadly turns from him, but Merlin in despair promises his soul to the demon, if he but assist to deliver his King and his country. The demon breaks the chains and Merlin rushes with the knights into battle. During his absence Vivien prepares herself to receive her hero, but though she sees him return victorious he is wounded to death. The demon comes up to claim his victim, but Vivien, remembering Morgana's words, sacrifices herself piercing her heart at Merlin's feet. The demon disappears cursing heaven and earth, while Artus and his knights, though they sadly mourn for their hero, yet praise the victory of true love.

THE MERRY WIVES OF WINDSOR.

Comic Opera in three acts by OTTO NICOLAI.
Text by MOSENTHAL.

This charming opera has achieved the fame of its composer, of whom very little is known, except that he is the author of this really admirable musical composition, which is valued not only in Germany but all over Europe. Its overture is played by almost every orchestra, and the choruses and songs are both delightful and original. As may be gathered from the title, the whole amusing story is taken from Shakespeare's comedy.

Falstaff has written love-letters to the wives of two citizens of Windsor, Mrs. Fluth and Mrs. Reich. They discover his duplicity and decide to punish the infatuated old fool.
