Presently a tall man approached them, greeting them respectfully, and Bertalda fancied she saw a resemblance to the master of the fountain in the imperial city. Still more unmistakable grew the likeness, when Undine angrily and almost threateningly waved him off, and he retreated with hasty steps and shaking head, as he had done before, and disappeared into a neighboring copse. Undine, however, said: "Don't be afraid, dear Bertalda, this time the hateful master of the fountain shall do you no harm." And then she told her the whole story in detail, and who she was herself, and how Bertalda had been taken away from the fisherman and his wife, and Undine had gone to them. The girl was at first terrified with this relation; she imagined her friend must be seized with sudden madness, but she became more convinced that all was true, for Undine's story was so connected, and fitted so well with former occurrences, and still more she had that inward feeling with which truth never fails to make itself known to us. It seemed strange to her that she was now herself living, as it were, in the midst of one of those fairy tales to which she had formerly only listened. She gazed upon Undine with reverence, but she could not resist a sense of dread that seemed to come between her and her friend, and at their evening repast she could not but wonder how the knight could behave so lovingly and kindly toward a being who appeared to her, since the discovery she had just made, more of a phantom than a human being.
