30. Thrice were the Roman deputies put to death by the Britons, and yet these, when harassed by the incursions of the barbarous nations, viz. Of the Scots and Picts, earnestly solicited the aid of the Romans. To give effect to their entreaties, ambassadors were sent, who made their entrance with impressions of deep sorrow, having their heads covered with dust, and carrying rich presents, to expiate the murder of the deputies. They were favourably received by the consuls, and swore submission to the Roman yoke, with whatever severity it might be imposed. The Romans, therefore, came with a powerful army to the assistance of the Britons; and having appointed over them a ruler, and settled the government, returned to Rome: and this took place alternately during the space of three hundred and forty-eight years. The Britons, however, from the oppression of the empire, again massacred The Roman deputies, and again petitioned for succour. Once more the Romans undertook the government of the Britons, and assisted them in repelling their neighbours; and, after having exhausted the country of its gold, silver, brass, honey, and costly vestments, and having besides received rich gifts, they returned in great triumph to Rome. 31. After the above-said war between the Britons and Romans, the assassination of their rulers, and the victory of Maximus, who slew Gratian, and the termination of the Roman power in Britain, they were in alarm forty years. Vortigern then reigned in Britain. In his time, the natives had cause of dread, not only from the inroads of the Scots and Picts, but also from the Romans, and their apprehensions of Ambrosius.* * These words relate evidently to some cause of dispute between the Romans, Ambrosius, and Vortigern. Vortigern is said to have been sovereign of the Dimetae, and Ambrosius son to the king of the Damnonii. The latter was half a Roman by descent, and naturally supported the Roman interest: the former was entirely a Briton, and as naturally seconded by the original Britons.
