In the hall of his palace where, under the sooty rafters, there hung the heads, pelts, and horns of wild beasts, he held feasts to which all the harpers of Alca and of the neighbouring islands were invited, and he himself used to join in singing the praises of the heroes.

He was just and magnanimous, but inflamed by so ardent a love of glory that he could not restrain himself from putting to death those who had sung better than himself.
The monks of Yvern having been driven out by the pagans who ravaged Brittany, King Brian summoned them into his kingdom and built a wooden monastery for them near his palace.

Every day he went with Queen Glamorgan, his wife, into the monastery chapel and was present at the religious ceremonies and joined in the hymns.
Now among these monks there was a brother called Oddoul, who, while still in the flower of his youth, had adorned himself with knowledge and virtue.

The devil entertained a great grudge against him, and attempted several times to lead him into temptation.

He took several shapes and appeared to him in turn as a war-horse, a young maiden, and a cup of mead.
