The changes that crept over London during the centuries we are considering were so slow and so imperceptible that the ordinary observer must have thought the world was standing still. Always there had been the Church with its services, always the Friar in the street, always the market and the selds: he did not know, because he had no power of judging, that the City was growing richer, that the standard of comfort had risen immensely, that life was not so rude as it had been, that, perhaps, there was less violence. As much uncertainty there always was, for in the midst of life we are in death, and there were many terrors—the pestilence that stalked the streets, invisible, by day and by night, fire, famine, and war. The population of the City did not increase so fast as its wealth; there were more stately houses, more carved work, more gold and silver cups, finer tapestry, finer weapons, but the world, in the eyes of the ordinary citizen, stood still: as things had been, so they were still, so they would be till the end of all things; there was no hope, no thought of a larger and nobler humanity, all his hope lay beyond the world. Let us remember this fact, because it explains a great deal of mediæval history. West Chepe was the heart of the City: but it was not the Exchange. There was no Exchange. The merchants met in the most convenient place, that is to say, for foreign trade, in Thames Street. They had their houses for the most part in the sloping streets north of Thames Street; here they received the foreign merchants. The lesser sort transacted business at the tavern. As we continue our walk we discover that there are three or four principal streets in the City. The apparent labyrinth is pierced by parallel thoroughfares and by others at right angles, so that one need not be lost in the winding lanes. The most important is the street—if we may call that a continuous street which is interrupted at so many places—which enters at Newgate. It is here called Flesh-shambles or Newgate Street, but it is interrupted at Blowbladder Street, and it becomes Chepe; it is interrupted by the Poultry, and it goes along Cornhill and Leadenhall Street, and so out at Aldgate. It is crossed by Grasschurch Street and Bishopsgate Street and by a great number of narrow streets. Other streets of less importance are Candlewick Street, East Chepe, Tower Street, Walbrook, Lombard Street, Fenchurch Street, Watling Street, Knightrider Street, besides a great number of narrow lanes, themselves intersected by courts and alleys. Remark, however, that as yet every house of any importance has its garden. The citizen of London clings to his garden, however small it is.
