When the Kaiser, Karl, abode at Zurich, he dwelt in a house called "The Hole," in front of which he caused a pillar to be erected with a bell on the top of it, to the end that whoever demanded justice should have the means of announcing himself. One day, as he sat at dinner in his house, he heard the bell ring, and sent out his servants to bring the claimant before him; but they could find no one. A second and a third time the bell rang, but no human being was still to be seen. At length the Kaiser himself went forth, and he found a large serpent, which had twined itself round the shaft of the pillar, and was then in the very act of pulling the bell rope. "This is God's will," said the monarch. "Let the brute be brought before me. I may deny justice to none of God's creatures--man or beast." The serpent was accordingly ushered into the imperial presence; and the Kaiser spoke to it as he would to one of his own kind, gravely asking what it required. The reptile made a most courteous reverence to Charlemagne, and signed in its dumb way for him to follow. He did so accordingly, accompanied by his court; and the creature led them on to the water's edge, to the shores of the lake, where it had its nest. Arrived there, the Kaiser soon saw the cause of the serpent's seeking him, for its nest, which was full of eggs, was occupied by a hideous toad of monstrous proportions. "Let the toad be flung into the fire," said the monarch solemnly, "and let the serpent have possession of its nest restored to it." This sentence was carried at once into execution. The toad was burnt, and the serpent placed in possession. Charlemagne and his court then returned to the palace. Three days afterwards, as the Kaiser again sat at dinner, he was surprised at the appearance of the serpent, which this time glided into the hall unnoticed and unannounced. "What does this mean?" thought the king. The reptile approached the table, and raising itself on its tail, dropped from its mouth, into an empty plate which stood beside the monarch, a precious diamond. Then, again abasing itself before him, the crawling creature glided out of the hall as it had entered, and was speedily lost to view. This diamond the monarch caused to be set in a costly chased ring of the richest gold; and he then presented the trinket to his fair wife, the much-beloved Fastrada. Now this stone had the virtue of attraction, and whoso received it from another, so long as they wore it, received also the intensest love of that individual. It was thus with Fastrada, for no sooner did she place the ring on her finger than the attachment of Charlemagne, great before, no longer knew any bounds. In fact his love was more like madness than any sane passion. But though this talisman had full power over love, it had no power over death; and the mighty monarch was soon to experience that nothing may avert the fiat of destiny.
