The work which Niebuhr began has been carried on by a school of successors, until it must be said that the entire fabric of once-accepted early Roman history has been torn into shreds. And in its place has been substituted--practically nothing. It is true that Niebuhr himself, iconoclast that he was, could not free himself from that hypothesis-forming tendency which is the heritage of all active minds, and put forward many prosaic guesses at the truth as substitutes for the old-time poetical guesses which he had dethroned. But these latter-day hypotheses, though accepted for the moment by many disciples of the master historian, have been treated with far scanter courtesy by the newer generation of critics, many of whom, however, have in turn supplied their own surmises. The net result of all the researches of the past century, and of all the surmises with which these researches have been supplemented, is to leave us practically without any acceptable hypothesis, except perhaps a meagre though consistent outline of institutional and civic development. And scarcely less vague are the outlines of the story of the early growth of Rome, and of its internal government and external accomplishments during some centuries of its undoubted existence. That it was ruled in the early days by kings, has been accepted on the basis of universal tradition, but it can scarcely be said that any one of these kings is to be regarded to-day as a known historic personage. We are not even sure as to the time when the kings were banished and a republican form of government supplanted the monarchy, though the accepted dates ascribe this transition to the year 509 B.C.--which, curiously enough, was the time of the banishment of the Pisistratidæ from Athens. If this date be accepted, it would seem that the evolution of political ideas in Greece was curiously paralleled by the growth of the same spirit in Rome, and it would follow that the civilisations of the two peoples were more closely contemporaneous than they are usually considered to have been.
