Chap. XVII Cadwallader Is by the Voice of an Angel Deterred From Returning to Britain
After some time, when the people had recovered strength, Cadwallader, being mindful of his kingdom, which was now free from the contagion of the pestilence, desired assistance of Alan towards the recovery of his dominions. The king granted his request; but as he was getting ready a fleet, he was commanded by the loud voice of an angel to desist from his enterprise. For God was not willing that the Britons should reign any longer in the island, before the time came of which Merlin prophetically foretold Arthur. It also commanded him to go to Rome to pope Sergius, where, after doing penance, he should be enrolled among the saints. It told him withal, that the Britons, by the merit of their faith, should again recover the island, when the time decreed for it was come. But this would not be accomplished before they should be possessed of his reliques, and transport them from Rome into Britain. At the same time also the reliques of the other saints should be found, which had been hidden on account of the invasion of pagans; and then at last would they recover their lost kingdom. When the holy prince had received the heavenly message, he went straight to king Alan, and gave him an account of what had been told him.
