themselves under the patronage of some saint, and had pious foundations for the celebration of their feasts, and for assisting each other in their necessities.” Although his long note refers principally to the industrial organization of the city of Barcelona, it is acknowledged that Catalonia borrowed many of its customs and usages in this matter from the towns of Italy. Before the middle of the fourteenth century there were over two hundred drapers’ shops in Florence, in which from seventy to eighty thousand pieces of cloth were made every year, to the value of 1,200,000 gold florins, and employing more than thirty thousand people. The historian John Villani says that the trade had been still more flourishing, when there were three hundred shops open and one hundred thousand pieces were made yearly, but that they were of a coarser quality and consequently did not bring as much money into the city, although more people got work. The art of dyeing cloths and other stuffs was cultivated by the Italians during the middle ages with considerable success. Alum, which is much used for this purpose, was eagerly sought after, and the Genoese obtained from Michael Palæologus, on payment of an annual sum, the exclusive right of extracting it from a certain mine in the Morea that had previously been worked by Arabs, Catalans, and others. The lessees began operations with a force of fifty men, and soon built a castle to protect themselves, and finally a town, which was destroyed by the Turks in 1455. The Florentines were so expert in dyeing wool that the material was sent to them for the purpose from other parts of Italy, and even from Germany and the Netherlands. It was only in 1858 that an immense wooden building for stretching and drying cloth in the sun, called _Il tiratoio della lana_, which had been used for over five hundred years, was torn down as too liable to catch fire. The cloths of France and other northern countries found a sale in Florence, not so much for home use as for exportation through the Genoese and Venetians. An exception, however, must be made for a rich article called _say_, manufactured in Ireland, and esteemed so beautiful as to be worn by the ladies of that refined city.[33] John Villani, already mentioned, says that there was a quarter of Florence called Calimala, containing twenty stores of the coarser cloths of the North, of which thirty thousand pieces, of the value of three hundred thousand gold florins, were yearly imported.
