Lambeccius narrates that he once told Emperor Leopold I (1657–1675) of a magic gold ring, said to have been long preserved in the Austrian treasury, and whose special virtue was that it could be used as an oracle to foretell the results of an approaching battle. If victory was to crown the Austrian army, this ring would shine with an unwonted splendor. It was said to be made from the gold offered by the Magi to the Infant Jesus. While, however, sacred ceremonies were being performed before the Emperor Frederick, grandson of Rudolph I., just before his departure for a disastrous battle with Louis of Bavaria, the ring vanished from the eyes of man. Later, it was said to have been recovered and Lambeccius suggested that a ring he had recently observed in the treasury, bearing certain characters difficult of interpretation, might be the ring made from the offering of the Magi.[521] The omen of victory observable in this ring must have been suggested by what Josephus writes of the high-priest’s breastplate. According to his story “God announced victory in battle” by means of the twelve stones set in this breastplate, and he proceeds “such a splendour shone from them when the army was not yet in motion, that all the people knew God himself was present to aid them.” A magic ring was made in the seventeenth century by a Florentine monk, named Nicolaus; this was designed to drive away gnats. It bore a charmed figure executed during the ascendency of the planet Saturn. The charm is said to have worked successfully. Since Saturn was usually regarded as a bearer of ill-luck, the operation of the magic figure must have depended upon sympathetic magic, the enlisting of the help of an evil power to combat a nature-plague.[522] It is related that long ago in the Principality of Anhalt, a princess had the habit of going to the window after dinner and shaking out the crumbs from her napkin. Intention or chance induced a great toad to station itself under this window so as to eat up the precious crumbs. In due time the princess was wedded, and one night, shortly before the birth of a child, she saw a maid enter the room with a lighted candle in her hand. Approaching the bedside she handed a gold ring to the princess, telling her at the same time that it was sent by the toad, out of gratitude for the food she had given it, with the earnest warning to guard the ring carefully, as the fortunes of Anhalt were bound up with it. Moreover, every precaution was to be taken on Christmas Eve to guard against fire.[523] It is stated that this ring was still to be seen in Dessau in 1722, and that it was customary to put out all the fires in the palace on Christmas Eve, and to have watchmen patrol the building all through the night.[524]
