It is not my intention to detain the reader by expatiating on the variety or the importance of the subject, which I have undertaken to treat; since the merit of the choice would serve to render the weakness of the execution still more apparent, and still less excusable.

But as I have presumed to lay before the public a first volume only [1] of the History of the Decline and Fall of the Roman Empire, it will, perhaps, be expected that I should explain, in a few words, the nature and limits of my general plan.
[Footnote 1: The first volume of the quarto, which contained the sixteen first chapters.] The memorable series of revolutions, which in the course of about thirteen centuries gradually undermined, and at length destroyed, the solid fabric of human greatness, may, with some propriety, be divided into the three following periods: I.The first of these periods may be traced from the age of Trajan and the Antonines, when the Roman monarchy, having attained its full strength and maturity, began to verge towards its decline; and will extend to the subversion of the Western Empire, by the barbarians of Germany and Scythia, the rude ancestors of the most polished nations of modern Europe.

This extraordinary revolution, which subjected Rome to the power of a Gothic conqueror, was completed about the beginning of the sixth century.
II.

The second period of the Decline and Fall of Rome may be supposed to commence with the reign of Justinian, who, by his laws, as well as by his victories, restored a transient splendor to the Eastern Empire.

It will comprehend the invasion of Italy by the Lombards; the conquest of the Asiatic and African provinces by the Arabs, who embraced the religion of Mahomet; the revolt of the Roman people against the feeble princes of Constantinople; and the elevation of Charlemagne, who, in the year eight hundred, established the second, or German Empire of the West III.
