In 1773 some of the Pietist monks were still living in their rude monastery whose ruins are visible on the banks of the Wissahickon. Chief among these mystics was an old man who might have enjoyed the wealth and distinction warranted by a title had he chosen to remain in Germany, but he had forsworn vanities, and had come to the new world to pray, to rear his children, and to live a simple life. Some said he was an alchemist, and many believed him to be a prophet. The infrequent wanderer beside the romantic river had seen lights burning in the window of his cell and had heard the solemn sound of song and prayer. On a winter night, when snow lay untrodden about the building and a sharp air stirred in the trees with a sound like harps, the old man sat in a large room of the place, with his son and daughter, waiting. For a prophecy had run that on that night, at the third hour of morning, the Deliverer would present himself. In a dream was heard a voice, saying, “I will send a deliverer to the new world who shall save my people from bondage, as my Son saved them from spiritual death.” The night wore on in prayer and meditation, and the hours tolled heavily across the frozen wilderness, but, at the stroke of three, steps were heard in the snow and the door swung open. The man who entered was of great stature, with a calm, strong face, a powerful frame, and a manner of dignity and grace.
