The First Book, therefore, contains a succinct account of the English, from the time of their descent on Britain, till that of King Egbert, who, after the different Princes had fallen by various ways, gained the monarchy of almost the whole island.

But as among the English arose four powerful kingdoms, that is to say, of Kent, of the West Saxons, of the Northumbrians, and of the Mercians, of which I purpose severally to treat if I have leisure; I shall begin with that which attained the earliest to maturity, and was also the first to decay. This I shall do more clearly, if I place the kingdoms of the East Angles, and of the East Saxons, after the others, as little meriting either my labours, or the regard of posterity.

The Second Book will contain the chronological series of the Kings to the coming of the Normans.

The three following Books will be employed upon the history of three successive kings, with the addition of whatever, in their times, happened elsewhere, which, from its celebrity, may demand a more particular notice. This, then, is what I purpose, if the Divine favour shall smile on my undertaking, and carry me safely by those rocks of rugged diction, on which Elward, in his search after sounding and far-fetched phrases, so unhappily suffered shipwreck. “Should any one, however,” to use the poet’s expression,[16] “peruse this work with sensible delight,” I deem it necessary to acquaint him, that I vouch nothing for the truth of long past transactions, but the consonance of the time; the veracity of the relation must rest with its authors. Whatever I have recorded of later times, I have either myself seen, or heard from credible authority. However, in either part, I pay but little respect to the judgment of my contemporaries: trusting that I shall gain with posterity, when love and hatred shall be no more, if not a reputation for eloquence, at least credit for diligence.

_Of the arrival of the Angles, and of the Kings of Kent._ [A.D. 449.]

In the year of the incarnation of our Lord 449, Angles and Saxons first came into Britain; and although the cause of their arrival is universally known, it may not be improper here to subjoin it: and, that the design of my work may be the more manifest, to begin even from an earlier period. That Britain, compelled by Julius Cæsar to submit to the Roman power, was held in high estimation by that people, may be collected from their history, and be seen also in the ruins of their ancient buildings. Even their emperors, sovereigns of almost all the world, eagerly embraced opportunities of sailing hither, and of spending their days here. Finally, Severus and Constantius, two of their greatest princes, died upon the island, and were there interred with the utmost pomp. The former, to defend this province from the incursions of the barbarians, built his celebrated and well-known wall from sea to sea. The latter, a man, as they report, of courteous manners, left Constantine, his son by Helena, a tender of cattle,[17] a youth of great promise, his heir. Constantine, greeted emperor by the army, led away, in an expedition destined to the continent, a numerous force of British soldiers; by whose exertions, the war succeeding to his wishes, he gained in a short time the summit of power. For these veterans, when their toil was over, he founded a colony on the western coast of Gaul, where, to this day, their descendants, somewhat degenerate in language and manners from our own Britons, remain with wonderful increase.[18]
