Ever to mind and consider with thyself; how all things that now are, have been heretofore much after the same sort, and after the same fashion that now they are: and so to think of those things which shall be hereafter also. Moreover, whole dramata, and uniform scenes, or scenes that comprehend the lives and actions of men of one calling and profession, as many as either in thine own experience thou hast known, or by reading of ancient histories; (as the whole court of Adrianus, the whole court of Antoninus Pius, the whole court of Philippus, that of Alexander, that of Croesus): to set them all before thine eyes. For thou shalt find that they are all but after one sort and fashion: only that the actors were others.
