Leading her gently back to the illuminated grounds, Lothario soothed his companion as best he could, feeling strangely that her sorrows were his own; and when, carried away by her jealous emotions on hearing another loud burst of applause ring out upon the evening air, Mignon uttered a rash wish that the building in which her rival now triumphed might suddenly burst into flames, a curious gleam came into the old harper's wild eyes, and he left her side at once.

In a few minutes he returned, and told her exultingly that, in accordance with her desire, he had set the castle on fire, and that the flames would soon burst forth; but before Mignon could fully grasp the meaning of what her half-witted friend had done to prove his zeal on her behalf, the festive entertainment came to an end, and guests and performers alike came out into the illuminated grounds to refresh themselves in the cool evening air.

The praises of Filina were being sung on every side, and as the triumphant actress came forth on the arm of Wilhelm, she was received with great enthusiasm. Wilhelm soon noticed Mignon standing in the gloom with Lothario, and hurrying forward, he greeted her with tenderness, for, alarmed at her prolonged absence, he had been searching for her. Filina, hating to see the two together, soon joined them, and desired Mignon to return to the theatre and fetch a bouquet she had left upon the stage; and Mignon, her despair brought back by the voice of Wilhelm, hurried into the doomed castle at once, remembering Lothario's words, and hoping to be overcome by the fumes within.

The interior of the castle was already burning fiercely; and as the startled guests suddenly saw flames bursting out from the building they had just left, they rejoiced at their own safety.

But Mignon was within the burning castle; and quickly realising her danger, Wilhelm, with a cry of horror, dashed through the smoking doorway to seek for her. Struggling against the fumes and suffocating heat, he made his way to the theatre, and finding Mignon lying half-dazed upon the already burning stage, he snatched her up in his arms, and, despite her frantic pleading that she might be left to her fate, bore her triumphantly through the blinding smoke into the safety of the grounds beyond.

Here he was quickly joined by Lothario, upon whom he saw that the recent excitement had had the effect of restoring his reason to its normal balance and clearness, for, to his surprise, the old harper presently announced in cool, decided tones his intention of conveying the unconscious girl to the palace of Cipriani in Italy, where he had influence to secure her every attention and care.

Seeing that Lothario was in earnest, and would not be diverted from his purpose, Wilhelm agreed to help the old man in conveying Mignon to Italy; for he now felt drawn to the beautiful young girl more closely than ever, and already his passing fancy for the frivolous coquette, Filina, was dying away.

So with every care and tenderness the old man and his young companion bore the hapless Mignon to Italy; but upon arriving at the palace of Cipriani—a stately building upon the borders of a beautiful lake—the poor girl fell into a fever, brought on by the dangerous excitement and mental suffering she had lately endured.

Wilhelm found to his astonishment that the directions and commands of Lothario were all obeyed by the servants of the palace as though the old harper were their master, but he scarce found time even to wonder at this, for all his thoughts were now centred on the suffering Mignon. In her delirium, the poor girl constantly breathed his name, thus betraying her passionate love for him; and as Wilhelm gazed upon the sweet, pale face of the fair maiden he had rescued, and remembered her wonderful devotion and gratitude to him, an answering passion, deep and tender, gradually awakened within his own breast. So, one day, when at last Mignon had sufficiently recovered to be brought into a large, sunny room overlooking the sparkling lake, the young student told her of his love, and Mignon's faithful heart was filled with joy and sweet content.
