Mahaffy, Boston, 1886, V, i, 273), but says, “Extensive sanitary works were undertaken throughout all Italy, and the celebrated Galen, who was almost a contemporary, extols their happy effects upon the public health.” But Galen does not have sanitary considerations especially in mind, since he mentions Trajan’s road-building only by way of illustration, comparing his own systematic treatment of medicine to the emperor’s great work in repairing and improving the roads, straightening them by cut-offs that saved distance, but sometimes abandoning an old road that went straight over hills for an easier route that avoided them, filling in wet and marshy spots with stone or crossing them by causeways, bridging impassable rivers, and altering routes that led through places now deserted and beset by wild beasts so that they would pass through populous towns and more frequented areas. The passage thus bears witness to a shifting of population.
