Master-weavers were many in the best years of tapestry weaving; indeed, a man must have attained the dignity and ability of that position before being able to produce those marvels of skill which were woven between 1475 and 1575 in Flanders, France and Italy. Their aids, the apprentices, pique the fancy, as Puck harnessed to labour might do. They were probably as mischievous, as shirking, as exasperating as boys have ever known how to be, but those little unwilling slaves of art in the Middle Ages make an appeal to the imagination more vivid than that of the shabby lunch-box boy of to-day. DYERS Accessory to the weavers, and almost as important, were the dyers who prepared the thread for use. The conscientiousness of their work cries out for recognition when the threads they dyed are almost unaltered in colour after five hundred years of exposure to their enemies, light and air. Dye stuffs were precious in those days, and so costly that even threads of gold and silver (which in general were supplied by the client ordering the tapestry) hardly exceeded in value certain dyed wools and silk. All of these workers, from director down to apprenticed lad, were bound by the guild to do or not do, according to its infinite code, to the end that the art of tapestry-making be held to the highest standards. The laws of the guilds make interesting reading. The guild prevailed all over Europe and regulated all crafts. In Florence even to-day evidences of its power are on every side, and the Guildhall in London attests its existence there. Moreover, the greatest artists belonged to the guilds, uniting themselves usually by work of the goldsmith, as Benvenuto Cellini so quaintly describes in his naive autobiography. GUILDS It was these same protective laws of the guilds that in the end crippled the hand of the weaver. The laws grew too many to comply with, in justice to talent, and talent with clipped wings could no longer soar. At the most brilliant period of tapestry production Flanders was to the fore. All Europe was appreciating and demanding the unequalled products of her ateliers. It was but human to want to keep the excellence, to build a wall of restrictions around her especial craft that would prevent rivals, and at the same time to press the ateliers to execute all the orders that piled in toward the middle of the Sixteenth Century. But although the guilds could make wise laws and enforce them, it could not execute in haste and retain the standard of excellence. And thus came the gradual decay of the art in Brussels, a decay which guild-laws had no power to arrest. GOTHIC PERIOD
