When all the people were assembled on the river-side, Frederick of Telramund came forward and accused the Princess Elsa of having murdered her brother in order to win the throne for herself; and then the King called upon Elsa to defend the charge made against her.

When the royal maiden appeared with her ladies, pale and sad, she looked so fair and pure that all the people felt her to be innocent; and as they gazed upon her, almost with awe, she presently stood forth and sang a beautiful song, describing the noble Knight she had seen in her dream, whom she felt would be her Champion. These were the words she sang:

"I saw in splendour shining, a Knight of glorious mien,
On me his eyes inclining with tranquil gaze serene;
A horn of gold around him, he leant upon his sword,
Thus when I erst espied him 'mid clouds of light he soared,
His words so low and tender brought life renewed to me;
My guardian, my defender, thou shalt my Champion be!"

When the song came to an end, the King was so struck with Elsa's angelic look that he declared so evil a deed could never have been done by one whom Heaven seemed to protect.

On hearing this, Telramund grew angry, and announcing that he had spoken the truth, he challenged any man who doubted his word to fight with him. The King now determined that Elsa's innocence or guilt should thus be proved by single combat, and calling upon her to name a champion who should fight for her, he said that Heaven alone should decide between them. If her Champion gained the victory, she should be declared innocent, but if Count Telramund overcame, they would know that she was guilty.

Elsa agreed to this, and said that her Champion should be the noble Knight of her dream; and then the King's herald blew a long, loud blast upon his trumpet, and cried out: "Who will do battle for Elsa of Brabant?"

There was a long, breathless pause, but no one answered the call. Again the herald called out: "Who will do battle for Elsa of Brabant?" Then Elsa stretched out her arms and prayed Heaven to send her the Champion she sought; and this time the call was answered.

A great shout arose from the people, and all eyes were turned towards the river; for there they saw, drawn by a beautiful white swan, a skiff approaching, in which stood a splendid Knight of glorious mien. He was clad entirely in dazzling silver armour, with a shining helmet upon his head, a golden horn at his side, and a flashing sword girt around his waist; and the beauty of his face and form, and the truth and purity that shone in his eyes, were so wondrous that everyone gazed upon him with speechless wonder.

When the skiff drew near to the shore, the Knight sprang lightly to the bank; but facing the river once again, he uttered a few words of thanks and farewell to the swan that had brought him thither:

"I give thee thanks, my faithful swan!
Turn thee again and breast the tide,
Return unto that land of dawn
Where joyous we did long abide.
Well thy appointed task is done;
Farewell, my trusty swan!"
