Now the heart of Brian, the nephew of the British King, was very sore because of the sufferings of his fellow-countrymen at the hands of the English conquerors. One day, as he hunted the otter with his uncle on the banks of a river, the King was overcome with heat and lay down to sleep, putting his head on the lap of the lad. But Brian’s heart was so heavy that his tears ran down upon the face of Cadwallon, who muttered uneasily: “It rains, it rains!” Then, opening his eyes, he saw the blue sky above him, and said to his nephew: “Surely there has been a shower, and now the sun is shining. But where is the rainbow?” And Brian said: “My lord, it shines upon the head of Edwin!” Then Cadwallon saw his tearful face, and asked him what he meant; and Brian told him all his woe. Whereupon Cadwallon swore to devote the rest of his life to winning back the land of Britain for her own people. But the strong King of Northumbria drove him back from his borders again and again, and almost in despair he set sail with Brian to seek help from Brittany. A great storm arose, however, drove the ship upon the rocks, and everyone was drowned save Cadwallon and his nephew, who were cast upon a desert island. There, says the tale, King Cadwallon would have died of hunger and heart-break had not the devoted Brian secretly cut off a slice of his own flesh, which he roasted and gave to his uncle, saying it was venison. The King ate and took courage, and after a time they were able to pass over the stormy sea in the wrecked boat to Brittany. The King of that land promised help, but meantime Brian heard that his sister had been taken a captive to Edwin’s Court, and that Edwin himself was much under the influence of a certain clever counsellor, who was especially hostile to the Britons. So Brian, dressed in beggar’s rags, but carrying a spiked staff, crossed to Wessex, and made the long journey on foot to York to the palace of Edwin. Standing outside, among a crowd of outcasts, he presently saw his sister come forth from the Queen’s household with a pitcher on her head to draw water from the well. At once he pretended to ask alms of her, and meantime told her who he was, and bade her point out to him the wily counsellor among Edwin’s followers. At that moment the latter came out with a bag of money for the beggars, and Brian, rushing forward, pierced him to the heart with his pointed staff, and then vanished among the crowd. Fleeing from thence to Penda, the strong King of the Mercians, Brian won him over to his uncle’s side, and forthwith Cadwallon, Brian, and Penda marched against Edwin in a great battle, in which the King of Northumbria, Cadwallon’s foster-father, was defeated and slain. Penda took care to secure the northern kingdom for himself, but until his death Cadwallon earned his title to some extent by becoming undisputed ruler over Wales, Devon, Cornwall, and the land now known as Westmorland and Cumberland.
