A gentle tap at the door broke the silence, and made them all start: it sometimes happens that a mere trifle, coming quite unexpectedly, strikes the senses with terror. They looked at each other hesitating; the tap was repeated, accompanied by a deep groan, and the Knight grasped his sword. But the old man muttered, "If it is what I fear, it is not a sword that will help us!" Undine, however, stepped forward to the door, and said boldly and sharply, "If you are after any mischief, you spirits of earth, Kühleborn shall teach you manners."
The terror of the others increased at these strange words; they looked at the maiden with awe, and Huldbrand was just mustering courage to ask her a question, when a voice answered her from without: "I am no spirit of earth; call me, if you will, a spirit pent in mortal clay. If you fear God, and will be charitable, you dwellers in the cottage, open the door to me." Undine opened it before he had done speaking, and held out a lamp into the stormy night, so as to show them the figure of an aged Priest, who started back as the radiant beauty of Undine flashed upon his sight. Well might he suspect magic and witchery, when so bright a vision shone out of a mean-looking cottage; he accordingly began a canticle, "All good spirits give praise to the Lord!"
"I am no ghost," said Undine, smiling; "am I so frightful to behold? And you may see that a pious saying has no terrors for me. I worship God, too, and praise Him after my own fashion; He has not created us all alike. Come in, venerable father; you will find worthy folks here."
The holy man walked in, bowing and casting his eyes around, and looking most mild and venerable. Every fold of his dark garment was dripping with water, and so were his long white beard and hoary locks. The Fisherman and the Knight led him to a bedroom, and gave him change of clothing, while the women dried his wet garments by the hearth fire. The aged stranger thanked them with all humility and gentleness, but would by no means accept of the Knight's splendid mantle, which he offered him; he chose himself an old gray wrapper of the Fisherman's instead. So they returned to the kitchen; the dame up gave her own arm-chair to the Priest, and had no peace till he sat himself down on it: "For," said she, "you are old and weary, and a priest besides." Undine pushed her little footstool toward the good man's feet, and altogether behaved to him quite properly and gracefully. Huldbrand took notice of this, in a playful whisper; but she answered very gravely: "Because he is a servant of the Maker of us all; that is too serious for a jest."
Meantime the two men set meat and wine before their guest, and when he had recruited his strength a little, he began his story; saying that the day before he had left his monastery, which was a good way off beyond the lake, intending to visit the bishop at his palace, and report to him the distress which these almost supernatural floods had caused the monks and their poor tenantry. After going round a long way, to avoid these floods, he had been obliged toward evening to cross an arm of the overflowing lake, with the help of two honest sailors. "But," added he, "no sooner had our little vessel touched the waves, than we were wrapped in the tremendous storm, which is still raging over our heads now. It looked as if the waters had only awaited our coming to give a loose to their fury. The oars were soon dashed from the seamen's hands, and we saw their broken fragments carried further and further from us by the waves. We floated on the wave tops, helpless, driven by the furious tempest toward your shores, which we saw in the distance whenever the clouds parted for a moment. The boat was tossed about still more wildly and giddily: and whether it upset, or I fell out, I cannot tell. I floated on, till a wave landed me at the foot of a tree, in this your island."
"Ay, island indeed!" said the Fisherman. "It was a promontory but a short time ago. But, since the stream and our lake are gone raving mad together, everything about us is new and strange."
The Priest continued: "As I crept along the water-side in the dark, with a wild uproar around me, something caught my eye, and presently I descried a beaten pathway, which was soon lost in the shades; I spied the light in your cottage, and ventured to come hither; and I cannot sufficiently thank my heavenly Father, who has not only delivered me from the waters, but guided me to such kind souls. I feel this blessing the more, as it is very likely I may never see any faces but yours again."—"How so?" asked the fisherman. "Can you guess how long this fury of the elements may last?" replied the Priest. "And I am an old man. My stream of life may perhaps lose itself in the earth, before these floods subside. And besides, it may be the foaming waters will divide you from the forest more and more, till you are unable to get across in your fishing boat; and the people of the mainland, full of their own concerns, would quite forget you in your retreat."
Shuddering, and crossing herself, the Fisherman's wife exclaimed, "God forbid!" But the old man smiled at her, and said, "What creatures we are. That would make no difference, to you at least, my dear wife. How many years is it since you have set foot within the forest? And have you seen any face but Undine's and mine? Lately, indeed, we have had the good Knight and Priest besides. But they would stay with us; so that if we are forgotten in this island, you will be the gainer."
"So I see," said the dame; "yet somehow, it is cheerless to feel ourselves quite cut off from the rest of the world, however seldom we had seen it before."
"Then you will stay with us!" murmured Undine in a sweet voice, and she pressed closer to Huldbrand's side. But he was lost in deep thought. Since the Priest had last spoken, the land beyond the wild stream had seemed to his fancy more dark and distant than ever; while the flowery island he lived in—and his bride, the fairest flower in the picture—bloomed and smiled more and more freshly in his imagination. Here was the Priest at hand to unite them;—and, to complete his resolution, the old dame just then darted a reproving look at Undine, for clinging to her lover's side in the holy man's presence; an angry lecture seemed on the point of beginning. He turned toward the Priest, and these words burst from him: "You see before you a betrothed pair, reverend sir; if this damsel and the kind old people will consent, you shall unite us this very evening."
