The present History has been conducted on the same general plan with that of the Conquest of Mexico. In an Introductory Book, I have endeavored to portray the institutions of the Incas, that the reader may be acquainted with the character and condition of that extraordinary race, before he enters on the story of their subjugation. The remaining books are occupied with the narrative of the Conquest. And here, the subject, it must be allowed, notwithstanding the opportunities it presents for the display of character, strange, romantic incident, and picturesque scenery, does not afford so obvious advantages to the historian, as the Conquest of Mexico. Indeed, few subjects can present a parallel with that, for the purposes either of the historian or the poet. The natural development of the story, there, is precisely what would be prescribed by the severest rules of art. The conquest of the country is the great end always in the view of the reader. From the first landing of the Spaniards on the soil, their subsequent adventures, their battles and negotiations, their ruinous retreat, their rally and final siege, all tend to this grand result, till the long series is closed by the downfall of the capital. In the march of events, all moves steadily forward to this consummation. It is a magnificent epic, in which the unity of interest is complete. In the "Conquest of Peru," the action, so far as it is founded on the subversion of the Incas, terminates long before the close of the narrative. The remaining portion is taken up with the fierce feuds of the Conquerors, which would seem, from their very nature, to be incapable of being gathered round a central point of interest. To secure this, we must look beyond the immediate overthrow of the Indian empire. The conquest of the natives is but the first step, to be followed by the conquest of the Spaniards,--the rebel Spaniards, themselves,--till the supremacy of the Crown is permanently established over the country. It is not till this period, that the acquisition of this Transatlantic empire can be said to be completed; and, by fixing the eye on this remoter point, the successive steps of the narrative will be found leading to one great result, and that unity of interest preserved which is scarcely less essential to historic than dramatic composition. How far this has been effected, in the present work, must be left to the judgment of the reader.
