XIV. (49) And it may become us next to consider on what account this same man is represented as founding and building a city, for it is only a multitude of men who have need of a city to dwell in; but the three who were the only human beings in existence at that time might have thought the foot of a mountain, or a small cave, a most sufficient abode. And I said, indeed, the three; but in all probability I might have spoken of him by himself; for the parents of Abel, who had been so treacherously slain, would never have endured to inhabit the same city with his murderer--a man who had committed fratricide, which is a greater pollution than even homicide. (50) For it is plain that it is not only extraordinary, but utterly contrary to all reason, that one man should build a city. In what manner could he do it? He could not build even the most trifling portion of a house, unless he employed other men as his assistants. Would the same man be able at the same time to cut stones, to cut wood, to work in iron and in brass, and to throw the vast circumference of walls round the city? to build up propylaea, and inter-walls, and temples, and sacred precincts, and porticoes, and docks, and houses, and all the other public and private buildings which one is accustomed to find in a city? And moreover, besides all these things, would he be able to carry burdens, to move away masses of earth, to widen narrow passages, to make fountains and water-courses, and all the other things with which a city ought to be provided? (51) Perhaps, therefore, since all these ideas are inconsistent with truth, it would be better to look upon the statement as an allegory, and to say that Cain determined to build up his own doctrine like a city.
