In olden times in a lovely valley near the Seven Mountains, stood a cloister called Heisterbach. Even now parts of the walls of this old monastery remain, and it was not by the hand of time, but by the barbarism of foolish warfare, that its halls fell into ruins. The monks were driven away, the abbey was pulled down, and the stones were used for the building of a fortress.

Since that time, so the country folk relate, the spirits of the banished monks wander nightly among the ruins, raising mute accusations against their persecutors and the destroyers of their cells. Among them there was one, Gebhard, the last Prior of Heisterbach, who now, they say, wanders about the graves of the monks, and also haunts the burial-places of the Masters of Löwenburg and Drachenburg.

In the Middle Ages the monks of Heisterbach were very famous. Many a rare copy of the Holy Scriptures, many a highly learned piece of writing was sent out into the world from this hermitage, telling of the industry and learning of the pious monks.

There was one brother, still young in years, who distinguished himself by his learning. He was looked up to by all the other brethren, and even the gray-haired Father Prior had recourse to his stores of knowledge. But the poisonous worm of doubt began to gnaw at his soul; the mirror of his faith was blurred by his deep meditations. His keen eye would often wander over the faded parchment on which the living word of God was written, while his childlike believing heart, humbly submitting itself, would lamentingly cry out, "Lord, I believe, help Thou mine unbelief!" Like a ghost his restless doubts would hover about him, making his soul the scene of tormenting struggle.
