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.

One night with flushed face he had been meditating over a parchment. At daybreak he still remained engrossed in his thoughts. The morning sun threw his bright rays over the heavens, casting playful beams on the written roll in the monk's hands.

But he saw them not, his thoughts were wholly taken up by a passage which for months past had ever been hidden to him and had been the constant subject of his reflections, "A thousand years are but as a day in Thy sight."

His brain had already long tormented itself over the obscure words of the Psalmist, and with a great effort he had striven to blot it out of his memory, and now the words danced again before his weary eyes, growing larger and larger. Those confusing black signs seemed to become a sneering doubt hovering round him: "A thousand years are but as a day in Thy sight."

He tore himself away from the silent cell, seeking the cool solitude of the cloister-gardens. There with a heavy heart he paced the paths, torturing himself with horrid doubts.

His eyes were fixed on the ground, his mind was far away from the peaceful garden, and without being aware of what he was doing, he left the cloister-gardens and wandered out into the neighbouring forest. The birds in the trees greeted him cordially, the flowers opened their eyes at his approach; but the wretched man heard and saw nothing but the words: "A thousand years are but as a day in Thy sight."

His wandering steps grew feeble, his feverish brain weary from want of sleep. Then the monk sank down on a stone, and laid his troubled head against a tree.
