The great wall of China. From blog.chinatraveldepot.com
¨The Great Wall of China was finished at its most northerly location. The construction work moved up from the south-east and south-west and joined at this point. This system of building in sections was also followed on a small scale within the two great armies of workers, the eastern and western armies. It was carried out in the following manner: groups of about twenty workers were formed, each of which had to take on a section of the wall, about five hundred metres long. A neighbouring group then built a wall of similar length to meet them. But then afterwards, when the sections were fully joined, construction was not continued on any further at the end of this thousand-metre section. Instead the groups of workers were shipped off again to build the wall in completely different regions. Naturally, with this method many large gaps arose, which were filled in only gradually and slowly, many of them not until after it had already been reported that the building of the wall was complete. In fact, there are said to be gaps which have never been built in at all, although that’s merely an assertion which probably belongs among the many legends which have arisen about the structure and which, for individual people at least, are impossible to prove with their own eyes and according to their own standards, because the structure is so immense.
Now, at first one might think it would have been more advantageous in every way to build in continuous sections or at least continuously within two main sections. For the wall was conceived as a protection against the people of the north, as was commonly announced and universally known. But how can protection be provided by a wall which is not built continuously? In fact, not only can such a wall not protect, but the structure itself is in constant danger. Those parts of the wall left standing abandoned in deserted regions could always be destroyed easily by the nomads, especially by those back then who, worried about the building of the wall, changed their place of residence with incredible speed, like grasshoppers, and thus perhaps had an even better overall view of how the construction was proceeding than we did, the people who built it. However, there was really no other way to carry out the construction except the way it happened.¨
