A queer story has been told regarding the Genoese emerald. At one time when the government was hard pressed for money, the Sacro Catino was offered to a rich Jew of Metz as pledge for a loan of 100,000 crowns. He was loath to take it, as he probably recognized its spurious character, and when his Christian clients forced him to accept it under threats of dire vengeance in case of refusal, he protested that they were taking a base advantage of the unpopularity of his faith, since they could not find a Christian who would make the loan. However, when some years later the Genoese were ready to redeem this precious relic, they were much puzzled to learn that a half-dozen different persons claimed to have it in their possession, the fact being that the Jew had fabricated a number of copies which he had succeeded in pawning for large sums, assuring the lender in each case that the redemption of the pledge was certain. Among the celebrated emeralds noted by George Agricola[388] (1490-1555) was a large one preserved in a monastery near Lyons, France. This is also mentioned by Gesner, who states that it was shaped as a dish, or shallow cup, and was held to be the Holy Grail, like its rival at Genoa.[389] Another of Agricola’s emeralds was somewhat smaller, but nevertheless measured nine inches in diameter and was in the chapel of St. Wenceslaus, at Prague; this may have been a chrysoprase, as at the present day many fine specimens of this stone can be seen in St. Wenceslaus, where the walls are inlaid with the golden green gem-stone. Still another, larger than the last named, was set in the gold monstrance in Magdeburg, and was believed to have been the handle of Emperor Otho I’s knife, since it was perforated. Possibly, however, the emerald, if genuine, was an Oriental stone, for it was customary to pierce rubies, sapphires, emeralds, etc., in the East so as to string them for necklaces or attach them as pendants to a jewel. In the convent-church of St. Stephan, in Persian Armenia, erected about the middle of the seventeenth century, it is related by the French traveller Tavernier that there was preserved a cross said to be made out of the basin in which Christ washed the feet of the Apostles. Set in this cross was a white stone, and the priests asserted that when the cross was laid upon the body of one seriously ill, this stone would turn black if he were about to die, but would regain its white hue after his death.[390]
