Long before this, Normandy had depended on other branches of trade for its commercial prosperity. Its fabrics of woollen stuffs, its arms and cutlery, besides the agricultural productions of its fertile and well-cultivated soil, each furnished material for export on a large scale. The towns of Rouen and Caen were especially manufacturing cities, and were very rich. This was the case with Rouen particularly, which was situated on the Seine, and was at that time an extensive depôt for provisions and other merchandise which was sent down the river for export, or was imported for future internal consumption. Already Paris, the abode of kings, and the metropolis of government, began to foreshadow the immense development which it was destined to undergo, by becoming the centre of commercial affairs, and by daily adding to its labouring and mercantile population (Figs. 195 and 196). It was, however, outside the walls of Paris that commerce, which needed liberty as well as protection, at first progressed most rapidly. The northern provinces had early united manufacturing industry with traffic, and this double source of local prosperity was the origin of their enormous wealth. Ghent and Bruges in the Low Countries, and Beauvais and Arras, were celebrated for their manufacture of cloths, carpets, and serge, and Cambrai for its fine cloths. The artizans and merchants of these industrious cities then established their powerful corporations, whose unwearied energy gave rise to that commercial freedom so favourable to trade.
