The contemporary literature of the Thirty Years' War was very voluminous and is still very undi gested. Every variety of dates, figures, and num bers, every variety of judgment upon the principal characters engaged, makes a little task like mine extremely bewildering. NO great history Of the period as a whole has as yet been written. Pro fossor Anton Gindely's larger work treats, so far as. It has at present gone, only of the very early years Of the struggle. He has indeed published a smaller school-book on the whole subject, which has been translated into English, but this is avow edly only tentative, and he confesses that he has not explored the archives of Stockholm. But in those archives, if anywhere, it is probable that the true Gustavus Adolphus is to be found.
