There is considerable disagreement among historians themselves regarding certain historical points, but their differences are of minor importance so far as the present work is concerned. When such points were involved, I have simply endeavored to follow the best authorities. Lengthy or important quotations from other writers have been duly credited where they appear, hence no special mention is necessary in this place. Minor extracts are merely enclosed within quotation-marks. The Decline and Fall of the Roman Empire, 6 Vols., Philadelphia, 1872, is the edition of Gibbon's Rome from which quotations are made. To assist in simplifying the subject and in placing it before the reader in a concise, comprehensive manner, a number of useful diagrams have been added; for they serve about the same purpose in the study of a subject so complicated as do maps in the study of geography. I would especially call attention to the large "Diagram of the Revelation," where the various lines of prophetic truth are outlined in parallel series, enabling the reader to comprehend at once where the symbolic narrative returns to take up a new line of thought covering the same period of time. In these diagrams, however, no attempt has been made to set forth every phase of thought connected with the subject; only the main features have been outlined. Feeling directed by the Lord to undertake this work and realizing the greatness of the task, I have earnestly sought for divine wisdom and guidance, and I humbly acknowledge his gracious assistance in its prosecution; and while I can not indulge the hope that human fallibility has been overcome, yet I firmly believe that a careful reliance upon the Holy Spirit has been an effectual means of avoiding error and unfolding many of the hitherto mysterious prophecies of this wonderful book. To his worthy name I ascribe all praise and glory. The future, doubtless, will witness a still greater development of this subject; for men of God more worthy and possessing greater abilities will arise, who, beginning where we have left off, will continue its investigation and throw upon it additional light as yet unrevealed. That the Lord will bless The Revelation Explained to the good of his church upon earth and grant it a place, however small, in the cause of present truth, is my earnest prayer. Yours in Christ, F.G. Smith. _Grand Junction, Mich., June 26, 1906_. PREFACE TO FOURTH EDITION The reception accorded this work when it was first submitted to the public was more than gratifying to the author. The lapse of time has only tended to confirm still more strongly the fundamental nature of the principle of interpretation adopted. In order to supply the constant demand, the fourth edition is now issued.
