[Sidenote: _Matth. West._ noteth. 500.] After that Aurelius Ambrosius was dead, his brother Vter Pendragon (whome some call Aurelius Vterius Ambrosianus) was made king in the yeare of our Lord 500, in the seuenth yeare of the emperour Anastasius, and in the sixtéenth yeare of Clodoueus king of the Frenchmen. The cause why he was surnamed Pendragon, was, for that Merline the great prophet likened him to a dragons head, that at the time of his natiuitie maruelouslie appeared in the firmament at the corner of a blasing star, as is reported. But others supposed he was so called of his wisedome and serpentine subtiltie, or for that he gaue the dragons head in his banner. This Vter, hearing that the Saxons with their capteins Occa or Otta the sonne of Hengist, and his brother Osca had besieged the citie of Yorke, hasted thither, and giuing them battell, discomfited their power, and tooke the said Occa and Osca prisoners. [Sidenote: _Hector Boet._] From this varieth Hector Boetius in his chronicle of Scotland, writing of these dooings in Britaine: for he affirmeth, that the counterfeit moonke, which poisoned Aurelius Ambrosius, was suborned and sent to woorke that feat by Occa, and not by his brother Pascentius: and further, that about the selfesame time of Aurelius his death, his brother Vter Pendragon lay in Wales, not as yet fullie recouered of a sore sicknesse, wherewith of late he had béene much vexed. Yet the lords of Britaine after the buriall of Aurelius Ambrosius, came vnto him and crowned him king: and though he was not able to go against the Saxons (which as then by reason of Aurelius Ambrosius his death were verie busie, and more earnest in pursuing the warre than before) yet an armie was prepared and sent foorth with all conuenient spéed vnder the leading of one Nathaliod, a man neither of anie great ancient house, nor yet of skill in warlike affaires.
