This technology for translating the resonating tribal world into Euclidean lineality and visuality is automatic. Roman roads and Roman streets were uniform and repeatable wherever they occurred. There was no adaptation to the contours of local hill or custom. With the decline of papyrus supplies, the wheeled traffic stopped on these roads, too. Deprivation of papyrus, resulting from the Roman loss of Egypt, meant the decline of bureaucracy, and of army organization as well.
