Andreas seemed overwhelmed when he reported: "It [was] common to see ten or a dozen or fifty houses rising at once; but when one looks upon, not a dozen or fifty, but upon ten thousand houses rising and ten times that number of busy workmen coming and going, and listens to the noise of countless saws and hammers and chisels and axes and planes, he is bewildered."
