INFLUENCE ON INDUSTRY

T1he same causes which gave a new activity to commerce served to develop powerfully every resource of industry. At the time of the first Crusades there were no manufactories of silken stuffs but those of the Greeks, a species of industry they had taken from the Persians, but which they themselves were soon forced to give over to Sicily. Then artisans leaving the island taught the Italians the art of making silk. The industry occupied principally the members of the religious order of the Humilies, who invented, it is said, cloth of gold and of silver.

2In the cities of the Orient the Saracens, also, had manufactures of goods, and from them the crusaders bought textile fabrics of camels’ hair. These industries and those of the Greeks, whether the latter was transported to Palermo or remained in the Eastern Empire, were able to serve as models or as incentive, in Europe, to many establishments where wool was worked. There were some famous glass manufactories at Tyre. The sand which covers the environs of that town has the property of giving a high degree of transparence to the vitrified matter from which beautiful shapes were fashioned. These productions excited probably the emulation of Venice who drew great profit from her glassware, particularly in the fifteenth century when the use of metal vessels was abandoned for that of glass.

3Here are some particulars about inventions, the only ones we have been able to gather. Mills, whose motive power is wind, were invented in Asia Minor where running water is very scarce. It has been supposed that the crusaders introduced them into Europe in the twelfth century--a conjecture which would seem to be confirmed by the application of parts of windmills on a great number of old armorial bearings, but which certain other evidence does not permit us to adopt. Several writers have also presumed that the crusaders spread a knowledge of the invention of paper, which they had derived from the Greeks, throughout Europe.

4The Arabs excelled at metal working and they knew how to chase and encrust it. They invented the art of “damascening,” which gave to steel the brilliance and splendour of gold and silver. Antiquaries have observed that since the Crusades the stamping of coins and the imprint of seals seem less incorrect and some attribute this improvement to lessons learned from the Arabs. The crusaders, however indignant at the profanation of the Temple of Jerusalem, could not but admire the ornamentation of precious metals by which the columns and walls had been artistically treated in honour of Mohammed. They brought away with them more than five hundred silver vessels consecrated to the service of the false prophet. The process of enamelling metals and the use in painting of solid, bright colours may have been brought to perfection by the sight of these Arabian works of art. They also brought back from the Orient a quantity of rubies, hyacinths, emeralds, sapphires, and diamonds, and they found out how to set them in gold and silver, so as to give an undying charm through the taste of their mounting and their setting.
