9. In a wall on an estate called Ludwigstein, in Schleswig-Holstein, is to be seen a large stone bearing the imprint of a horse-shoe, wherewith is associated the following tale: One morning many years ago a horseman was riding along the road when the church prayer-bell rang, whereupon he swore an oath and said, “May the Devil take me if I am not again on this very spot this evening when the bell again sounds.” And indeed he kept his word, but at the stroke of the evening bell his horse slipped upon the stone and broke a leg, and the mark of a shoe is still to be seen there. 10. The Horse-Shoe imprint in the cemetery of the Church of Our Lady at Munster. During the building of this beautiful Gothic church in the fourteenth century, the Devil observed its shapely proportions with increasing displeasure, and bethought himself of various schemes to hinder the work’s progress. Finally he decided on trying to bewitch the architect’s senses. Accordingly he braided his hair, arrayed himself in gay female attire, bedecked with costly jewels, and appeared before the architect, whom he sought to ensnare with soft words and gifts. But the latter was not thus to be deceived. Leaning upon his measuring-rod, he listened unmoved to the beguiling conversation of the pretended belle, and rejected with scorn the gold and precious stones which she brought him. Thereupon the Devil became enraged, stamped upon the ground with vehemence, and disappeared, leaving behind him an evil smell; and the mark of one of the iron horse-shoes, wherewith he was shod, was deeply imprinted on a stone in the cemetery, and, according to popular report, is still to be found there. The impressions on stone of figures of horse-shoes, of which there are numerous examples in northern Europe, are regarded by some archæologists as sacred symbols of the pagans or relics of the cult of Wodan, and as showing the sites of ancient altars and burial places; while others maintain that these figures were originally intended as boundary marks. Numerous traditions associate them with battles fought in these localities, and in the popular fancy they are imagined to indicate the favorite haunts of witches, the meeting-places where they held their revels, the horse-shoe mark being an imprint of the Devil’s foot. These weird rendezvous were usually on the tops of mountains or hills, and are still known as Witches’ Dance-Places in different parts of Europe, especially in Germany. XX.
