In the composition of the work, I have, for the most part, conformed to the plan which I had before adopted. Far from confining myself to a record of political events, I have endeavored to present a picture of the intellectual culture and the manners of the people. I have not even refused such aid as could be obtained from the display of pageants, and court ceremonies, which, although exhibiting little more than the costume of the time, may serve to bring the outward form of a picturesque age more vividly before the eye of the reader. In the arrangement of the narrative, I have not confined myself altogether to the chronological order of events, but have thrown them into masses, according to the subjects to which they relate, so as to produce, as far as possible, a distinct impression on the reader. And in this way I have postponed more than one matter of importance to a later portion of the work, which a strict regard to time would assign more properly to an earlier division of the subject. Finally, I have been careful to fortify the text with citations from the original authorities on which it depends, especially where these are rare and difficult of access. In the part relating to the Netherlands I have pursued a course somewhat different from what I have done in other parts of the work. The scholars of that country, in a truly patriotic spirit, have devoted themselves of late years to exploring their own archives, as well as those of Simancas, for the purpose of illustrating their national annals. The results they have given to the world in a series of publications, which are still in progress. The historian has reason to be deeply grateful to those pioneers, whose labors have put him in possession of materials which afford the most substantial basis for his narrative. For what basis can compare with that afforded by the written correspondence of the parties themselves? It is on this sure ground that I have mainly relied in this part of my story; and I have adopted the practice of incorporating extracts from the letters in the body of the text, which, if it may sometimes give an air of prolixity to the narrative, will have the advantage of bringing the reader into a sort of personal acquaintance with the actors, as he listens to the words spoken by themselves. In the earlier part of this Preface, I have made the acknowledgments due for assistance I have received in the collection of my materials; and I must not now conclude without recording my obligations, of another kind, to two of my personal friends,--Mr. Charles Folsom, the learned librarian of the Boston Athenæum, who has repeated the good offices he had before rendered me in revising my manuscript for the press; and Mr. John Foster Kirk, whose familiarity with the history and languages of Modern Europe has greatly aided me in the prosecution of my researches, while his sagacious criticism has done me no less service in the preparation of these volumes.
