King Henry was a man who loved justice and exercised it, but his kingdom was in constant danger from inroads by wild Huns, and for this reason he wished to do whatever would win the favor of the powerful Count Telramund. When, however, he saw Elsa in all her beauty and innocence he hesitated in his purpose.
The plaintiff brought forward three men who testified that the duchess had entered into a secret union with one of her vassals. Only two of these men were shown to be perfidious; the testimony of the other seemed valid, though this was not enough to condemn her.
Then Telramund seized his sword, crying out that God Himself should be the judge, and that a duel should decide the matter. So a duel was arranged to take place three days later.
Elsa cast her eyes around the circle of nobles, but saw no one grasp his sword in defense of her innocence. Fear of the mighty warrior Telramund filled them all.
Remembering the little bell, she drew it forth from her pocket and rang it. The clear tones broke the stillness, grew louder and louder until they reached even the distant mountains.
"My champion will appear in the contest," she said; whereupon the count let forth such a mocking laugh that the hearts of all were filled with intense fear.
The day of the contest was at hand. The king sat on his high throne and watched the majestic river that sent its mighty waters through the valley. Princes and brave knights were gathered together. Before them stood Telramund, clad in armor, and at his side the accused Elsa, adorned with every grace that Nature can bestow.
Three times the mighty hero challenged some one to come forward as a champion for the accused girl, but no one stirred. Then arose from the Rhine the sound of sweet music; something silvery gleamed in the distance, and as it came nearer it was plain that it was a swan with silver feathers. With a silver chain he was pulling a small ship, in which lay sleeping a knight clad in bright armor.
When the bark landed, the knight awoke, rose, and blew three times on a golden horn. This was the signal that he took up the challenge. Quickly he strode into the lists.
"Your name and descent?" cried the herald.
