A quaint account is given by the Monk of St. Gall about a bell ordered by Charlemagne. Charlemagne having admired the tone of a certain bell, the founder, named Tancho, said to him: "Lord Emperor, give orders that a great weight of copper be brought to me that I may refine it, and instead of tin give me as much silver as I need,--a hundred pounds at least,--and I will cast such a bell for you that this will seem dumb in comparison to it." Charlemagne ordered the required amount of silver to be sent to the founder, who was, however, a great knave. He did not use the silver at all, but, laying it aside for his own use, he employed tin as usual in the bell, knowing that it would make a very fair tone, and counting on the Emperor's not observing the difference. The Emperor was glad when it was ready to be heard, and ordered it to be hung, and the clapper attached. "That was soon done," says the chronicler, "and then the warden of the church, the attendants, and even the boys of the place, tried, one after the other, to make the bell sound. But all was in vain; and so at last the knavish maker of the bell came up, seized the rope, and pulled at the bell. When, lo! and behold! down from on high came the brazen mass; fell on the very head of the cheating brass founder; killed him on the spot; and passed straight through his carcase and crashed to the ground.... When the aforementioned weight of silver was found, Charles ordered it to be distributed among the poorest servants of the palace." There is record of bronze bells in Valencia as early as 622, and an ancient mortar was found near Monzon, in the ruins of a castle which had formerly belonged to the Arabs. Round the edge of this mortar was the inscription: "Complete blessing, and ever increasing happiness and prosperity of every kind and an elevated and happy social position for its owner." The mortar was richly ornamented. At Croyland, Abbot Egebric "caused to be made two great bells which he named Bartholomew and Bethelmus, two of middle size, called Turketul and Tatwyn, and two lesser, Pega and Bega." Also at Croyland were placed "two little bells which Fergus the brass worker of St. Botolph's had lately given," in the church tower, "until better times," when the monks expressed a hope that they should improve all their buildings and appointments. Oil that dropped from the framework on which church bells were hung was regarded in Florence as a panacea for various ailments. People who suffered from certain complaints were rubbed with this oil, and fully believed that it helped them.
