mythologies, combined with influences favourable to the formation of strong habits of political and social duty. Religious art was sacrificed; that was the exclusive heritage of the Greek; but superior morality was on the whole the heritage of the Roman, and if he produced no good tragedy himself, he furnished characters for Shakespeare and Corneille. Whatever set the Romans free, or comparatively free, from the tyranny of tribal religion may be considered as having in the same measure been the source of the tolerance which was so indispensable a qualification for the exercise of dominion over a polytheistic world. They waged no war on "the gods of the nations," or on the worshippers of those gods as such. They did not set up golden images after the fashion of Nebuchadnezzar. In early times they seem to have adopted the gods of the conquered, and to have transported them to their own city. In later times they respected all the religions except Judaism and Druidism, which assumed the form of national resistance to the empire, and worships which they deemed immoral or anti-social, and which had intruded themselves into Rome. Another grand step in the development of law is the severance of the judicial power from the legislative and the executive, which permits the rise of jurists, and of a regular legal profession. This is a slow process. In the stationary East, as a rule, the king has remained the supreme judge. At Athens, the sovereign people delegated its judicial powers to a large committee, but it got no further; and the judicial committee was hardly more free from political passion, or more competent to decide points of law, than the assembly itself. In England the House of Lords still, formally at least, retains judicial functions. Acts of attainder were a yet more primitive as well as more objectionable relic of the times in which the sovereign power, whether king, assembly, or the two combined, was ruler, legislator, and judge all in one. We shall not attempt here to trace the process by which this momentous separation of powers and functions was to a remarkable extent accomplished in ancient Rome. But we are pretty safe in saying that the _praetor peregrinus_ was an important figure in it, and that it received a considerable impulse from the exigencies of a jurisdiction between those who as citizens came under the sovereign assembly and the aliens or semi-aliens who did not. Whether the partial explanations of the mystery of Roman greatness which we have here suggested approve themselves to the reader's judgment or not, it may at least be said for them that they are _verae causae_, which is not the case with the story of the foster-wolf, or anything derived from it, any more than with the story of the prophetic apparitions of Jupiter on the Capitoline Hill.
