History, then, must be our guide; and never was epoch more propitious, for never has her lamp shone brighter. The study of this important science, which Niebuhr truly calls the _magistra vitæ_, has received within our days an impulse such as it never had before. The invaluable archæological treasures which the linguists and antiquarians of Europe have rescued from the literature and monuments of the great nations of former ages, bring--as it were--back to life again the mouldered generations of the dim past. We no longer content ourselves with chronological outlines, mere names, and unimportant accounts of kings and their quarrels; we seek to penetrate into the inner life of those multitudes who acted their part on the stage of history, and then disappeared, to understand the modes of thought, the feelings, ideas, _instincts_, which actuated them, and made them what they were. The hoary pyramids of the Nile valley are forced to divulge their age, the date of a former civilization; the temples and sepulchres, to furnish a minute account of even the private life of their builders;[17] the arrow-headed characters on the disinterred bricks of the sites of Babylon and Nineveh, are no longer a secret to the indefatigable orientalists; the classic writers of Hindostan and China find their most zealous scholiasts, and profoundest critics, in the capitals of Western Europe. The dross of childish fables, which age after age has transmitted to its successor under the name of history, is exposed to the powerful furnace of reason and criticism, and the pure ore extracted, by such men as Niebuhr, Heeren, Ranke, Gibbon, Grote. The enthusiastic lover of ancient Rome now sees her early history in clearer, truer colors than did her own historians.
