Preface To The First Volume.

Diligence and accuracy are the only merits which an historical writer may ascribe to himself; if any merit, indeed, can be assumed from the performance of an indispensable duty. I may therefore be allowed to say, that I have carefully examined all the original materials that could illustrate the subject which I had undertaken to treat. Should I ever complete the extensive design which has been sketched out in the Preface, I might perhaps conclude it with a critical account of the authors consulted during the progress of the whole work; and however such an attempt might incur the censure of ostentation, I am persuaded that it would be susceptible of entertainment, as well as information.

At present I shall content myself with a single observation. The biographers, who, under the reigns of Diocletian and Constantine, composed, or rather compiled, the lives of the Emperors, from Hadrian to the sons of Carus, are usually mentioned under the names of Ælius Spartianus, Julius Capitolinus, Ælius Lampridius, Vulcatius Gallicanus, Trebellius Pollio and Flavius Vopiscus. But there is so much perplexity in the titles of the MSS., and so many disputes have arisen among the critics (see Fabricius, Biblioth. Latin. l. iii. c. 6) concerning their number, their names, and their respective property, that for the most part I have quoted them without distinction, under the general and well-known title of the Augustan History.

Preface To The Fourth Volume Of The Original Quarto Edition.

I now discharge my promise, and complete my design, of writing the History of the Decline and Fall of the Roman Empire, both in the West and the East. The whole period extends from the age of Trajan and the Antonines, to the taking of Constantinople by Mahomet the Second; and includes a review of the Crusades, and the state of Rome during the middle ages. Since the publication of the first volume, twelve years have elapsed; twelve years, according to my wish, "of health, of leisure, and of perseverance." I may now congratulate my deliverance from a long and laborious service, and my satisfaction will be pure and perfect, if the public favor should be extended to the conclusion of my work.

It was my first intention to have collected, under one view, the numerous authors, of every age and language, from whom I have derived the materials of this history; and I am still convinced that the apparent ostentation would be more than compensated by real use. If I have renounced this idea, if I have declined an undertaking which had obtained the approbation of a master-artist, * my excuse may be found in the extreme difficulty of assigning a proper measure to such a catalogue. A naked list of names and editions would not be satisfactory either to myself or my readers: the characters of the principal Authors of the Roman and Byzantine History have been occasionally connected with the events which they describe; a more copious and critical inquiry might indeed deserve, but it would demand, an elaborate volume, which might swell by degrees into a general library of historical writers. For the present, I shall content myself with renewing my serious protestation, that I have always endeavored to draw from the fountain-head; that my curiosity, as well as a sense of duty, has always urged me to study the originals; and that, if they have sometimes eluded my search, I have carefully marked the secondary evidence, on whose faith a passage or a fact were reduced to depend.

I shall soon revisit the banks of the Lake of Lausanne, a country which I have known and loved from my early youth. Under a mild government, amidst a beauteous landscape, in a life of leisure and independence, and among a people of easy and elegant manners, I have enjoyed, and may again hope to enjoy, the varied pleasures of retirement and society. But I shall ever glory in the name and character of an Englishman: I am proud of my birth in a free and enlightened country; and the approbation of that country is the best and most honorable reward of my labors. Were I ambitious of any other Patron than the Public, I would inscribe this work to a Statesman, who, in a long, a stormy, and at length an unfortunate administration, had many political opponents, almost without a personal enemy; who has retained, in his fall from power, many faithful and disinterested friends; and who, under the pressure of severe infirmity, enjoys the lively
