It is the ambition of all nations which enjoy a literary culture to possess a harmonious and vivid narrative of their own past history. And it is of inestimable value to any people to obtain such a narrative, which shall comprehend all epochs, be true to fact and, while resting on thorough research, yet be attractive to the reader; for only by this aid can the nation attain to a perfect self-consciousness, and feeling the pulsation of its life throughout the story, become fully acquainted with its own origin and growth and character. But we may doubt whether up to this time works of such an import and compass have ever been produced, and even whether they can be produced. For who could apply critical research, such as the progress of study now renders necessary, to the mass of materials already collected, without being lost in its immensity? Who again could possess the vivid susceptibility requisite for doing justice to the several epochs, for appreciating the actions, the modes of thought, and the moral standard of each of them, and for understanding their relations to universal history? We must be content in this department, as well as in others, if we can but approximate to the ideal we set up. The best-written histories will be accounted the best. 
When then an author undertakes to make the past life of a foreign nation the object of a comprehensive literary work, he will not think of writing its history as a nation in detail: for a foreigner this would be impossible: but, in accordance with the point of view he would naturally take, he will direct his eyes to those epochs which have had the most effectual influence on the development of mankind: only so far as is necessary for the comprehension of these, will he introduce anything that precedes or comes after them. 
There is an especial charm in following, century after century, the history of the English nation, in considering the antagonism of the elements out of which it is composed, and its share in the fortunes and enterprises of that great community of western nations to which it belongs; but it will be readily granted that no other period can be compared in general importance with the epoch of those religious and political wars which fill the sixteenth and seventeenth centuries.
