These accusations are, however, dismissed by the king and his men, since Elsa passionately refuses to credit them, and the wedding procession sweeps into the church, followed by the vindictive glances of Telramund and Ortrud,—glances which the trembling Elsa alone seems to perceive.
The third act takes place on that selfsame evening. The festivities are nearly ended, and through opposite doors the wedding procession enters the nuptial chamber to the accompaniment of the well known Bridal Chorus. The attendants soon depart, however, leaving Elsa and Lohengrin to join in a duet of happy married love. Now that they are alone together for the first time, Elsa softly begins chiding her lover for not showing more confidence in her, and revealing who he is. In spite of his tender attempts to turn aside the conversation into a less dangerous channel, she gradually becomes more importunate:—
‘Oh, make me glad with thy reliance,
Humble me not that bend so low.
Ne'er shalt thou rue thy dear affiance:
Him that I love, oh let me know!’
Seeing her husband does not yield to her tender pleading, Elsa then redoubles her caresses. Her faint suspicions have taken such firm root, and grow with such rapidity, that she is soon almost wild with suspense. All his attempts to soothe her only seem to excite her more, and suddenly, fancying that she hears the swan boat coming to bear him away from her, she determines to break the magic spell at any cost, as Ortrud cunningly advised her, and demands his name. Just as Lohengrin is gazing upon her in heart-rending but mute reproach, Telramund bursts into the room, with a band of hired assassins, to take his life. A quick motion from Elsa, whose trust returns when she sees her beloved in danger, permits Lohengrin to parry the first blow with his sword, and Frederick of Telramund soon lies dead upon the floor, while his accomplices cringe at Lohengrin's feet imploring his pardon. Day is dawning, and Lohengrin, after caring tenderly for the half-fainting Elsa, bids the would-be assassins bear the corpse into the presence of the king, where he promises to meet Elsa and satisfy all her demands:—
‘Bear hence the corpse into the king's judgment hall.
Into the royal presence lead her.
Arrayed as fits so fair a bride;
There all she asks I will concede her,
Nor from her knowledge aught will hide.’
At the last scene the king is again near the river, on his judgment throne, whence he watches the mustering of the troops which are to accompany him to the war, and makes a patriotic speech, to which they gladly respond. Suddenly, however, the four men appear with the corpse of Frederick of Telramund, which they lay at the king's feet, declaring they are obeying the orders of the new lord of Brabant, who will soon come to explain all. Before the king can question further, Elsa appears, pale and drooping, in spite of her bridal array, and just as the king is rallying her at wearing so mournful an expression when her bridegroom is only leaving her for a short time to lead his troops to the fray, the Swan Knight appears, and is enthusiastically welcomed by his men. Sadly he informs them he can no longer lead them on to victory, and declares that he slew Frederick of Telramund in self-defence, a crime for which he is unanimously acquitted.
Then he sadly goes on to relate that Elsa has already broken her promise, and asked the fatal question concerning his name and origin. Proudly he tells them that he has no cause to be ashamed of his lineage, as he is Lohengrin, son of Parsifal, the guardian of the Holy Grail, sent from the temple on Mount Salvatch to save and defend Elsa. The only magic he had used was the power with which the Holy Grail endowed all its defenders, and which never forsook them until they revealed their name:—
‘He whom the Grail to be its servant chooses
Is armed henceforth by high invincible might;
All evil craft its power before him loses,
The spirit of the darkness where he dwells takes flight.
Nor will he lose the awful charm it lendeth,
Although he should to distant lands,
When the high cause of virtue he defendeth:
While he's unknown, its spells he still commands.’
Now, he adds, the sacred spell is broken, he can no longer remain, but is forced to return immediately to the Holy Grail, and in confirmation of his word the swan and skiff again appear, sailing up the river. Tenderly the Swan Knight now bids the repentant Elsa farewell, gently resisting her passionate attempts to detain him, and giving her his sword, horn, and ring, which he bids her bestow upon her brother when he returns to protect her. This boon is denied him, because she could not keep faith with him for one short year, at the end of which time he would have been free to reveal his name, and her missing brother would have been restored to her by the power of the Holy Grail.
Placing the fainting Elsa in her women's arms, Lohengrin then goes down toward the swan boat, amid the loud lamentations of all the people, One person only is glad to see him depart, Ortrud, the wife of Telramund, and, thinking he can no longer interfere, she cruelly taunts Elsa with her lack of faith, and confesses that her magic arts and heathen spells have turned the heir of Brabant into the snowy swan which is even now drawing the tiny skiff.
