The Story of Breccan
The story of Breccan is related in Cormac's Glossary. He was a merchant who traded between Ireland and Scotland with fifty corracles. Now there was a great whirlpool at Rathlin Island caused by the meeting of the seas, and they formed a caldron vast enough to swallow all Ireland. And it happened on a time that Breccan and all his corracles were lost and engulfed in this caldron. Not a man was left to tell the tale of how or where they had perished. Thus it was that the skull of a small animal being discovered on the beach, it was brought to the blind poet, who laying his staff on it obtained the inner vision by which he revealed the fate of Breccan and his fifty corracles.
