impression which each makes upon the tottering fabric of the Roman greatness, connects their distant movements, and measures the relative importance assigned to them in the panoramic history. The more peaceful and didactic episodes on the development of the Roman law, or even on the details of ecclesiastical history, interpose themselves as resting-places or divisions between the periods of barbaric invasion. In short, though distracted first by the two capitals, and afterwards by the formal partition of the empire, the extraordinary felicity of arrangement maintains an order and a regular progression. As our horizon expands to reveal to us the gathering tempests which are forming far beyond the boundaries of the civilized world—as we follow their successive approach to the trembling frontier—the compressed and receding line is still distinctly visible; though gradually dismembered and the broken fragments assuming the form of regular states and kingdoms, the real relation of those kingdoms to the empire is maintained and defined; and even when the Roman dominion has shrunk into little more than the province of Thrace—when the name of Rome, confined, in Italy, to the walls of the city—yet it is still the memory, the shade of the Roman greatness, which extends over the wide sphere into which the historian expands his later narrative; the whole blends into the unity, and is manifestly essential to the double catastrophe of his tragic drama. But the amplitude, the magnificence, or the harmony of design, are, though imposing, yet unworthy claims on our admiration, unless the details are filled up with correctness and accuracy. No writer has been more severely tried on this point than Gibbon. He has undergone the triple scrutiny of theological zeal quickened by just resentment, of literary emulation, and of that mean and invidious vanity which delights in detecting errors in writers of established fame. On the result of the trial, we may be permitted to summon competent witnesses before we deliver our own judgment. M. Guizot, in his preface, after stating that in France and Germany, as well as in England, in the most enlightened countries of Europe, Gibbon is constantly cited as an authority, thus proceeds:—
