Probably the earliest notice of the peculiar superstition in regard to the turquoise—namely, that it preserves the wearer from injury in case of falling—is contained in Volmar’s thirteenth century “Steinbuch,” where we read:
Whoever owns the true turquoise set in gold will not injure any of his limbs when he falls, whether he be riding or walking, so long as he has the stone with him.[157]
Anselmus de Boot, court physician of Emperor Rudolph II, tells a story of a turquoise that, after being thirty years in the possession of a Spaniard, was offered for sale with the rest of the owner’s property. Every one was amazed to find it had entirely lost its color; nevertheless De Boot’s father bought it for a trifling sum. On his return home, however, ashamed to wear so mean-looking a gem, he gave it to his son, saying, “Son, as the virtues of the turquoise are said to exist only when the stone has been given, I will try its efficacy by bestowing it upon thee.” Little appreciating the gift, the recipient had his arms engraved on it as though it had been only a common agate and wore it as a signet. He had scarcely worn it a month, however, before it resumed its pristine beauty and daily seemed to increase in splendor. Could we accept this statement as true we would have here an altogether unique instance of the recovery by a turquoise of the blue color it had lost.
Not long after, the powers of De Boot’s turquoise were put to the test. As he was returning to Bohemia from Padua, where he had just taken his degree, he was forced to traverse a narrow and dangerous road at night. Suddenly his horse stumbled and threw him heavily to the ground, but, strange to say, neither horse nor rider was injured by the fall. Next morning, while washing his hands, De Boot remarked that about a quarter of his turquoise had broken away. Nevertheless the stone did not lose its virtue. Some time afterward, when the wearer was lifting a very heavy pole, he felt all at once a sharp pain in his side and heard his ribs crack, so that he feared he had injured himself seriously. However, it turned out that he had not broken any bones but had simply strained himself; but, on looking at his turquoise, he saw that it had again broken into two pieces.[158]
