The Historians' History of the World 08

Naval architecture learned a lesson from several abuses which the Crusades momentarily had introduced into the art. Ships of excessive capacity, too weak, and of faulty proportions had been hastily built in order to accommodate the crowd of pilgrims. Seamen who wished their voyages to be more lucrative and passengers desirous of travelling in companies began to adopt these ungainly vessels. However, this departure from the principles of shipbuilding caused the loss of many fleets and brought about a fortunate innovation in naval architecture. Experience taught that a single mast was not sufficient in a vessel of great size, and we may trace to this period the custom of furnishing several masts to a single ship—a custom whose antiquity is well proven, but whose origin is somewhat shadowed in doubt.

An increase in the number of sails must of necessity follow the adoption of more than one mast; ships were no longer stopped in their course for lack of a directly favourable wind,—by trimming the sails with skill the seaman progressed nearly always towards his destination. The art of sailing for a certain point with the wind nearly dead ahead must certainly be counted as one of the most ingenious and important discoveries ever made.

INFLUENCE ON INDUSTRY

The 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.

In 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. Here 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.

The 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.

THE MASONS ORGANISE

The Crusades contributed indirectly to the progress of art in that they caused religious orders and devout establishments to be multiplied. The number of sacred edifices which rose up at that time throughout Europe is truly prodigious. Nobles and even those who had little piety were ambitious for the title of “founder of a church.” While they may have wrecked temples in one place, it was often their pleasure to build them in others.
