Note 49a — TO THE READER.

Maelgwn Gwynedd.—He became lord over the whole of Wales about the year 550 and regained much territory that had once been lost to the Saxons. Indeed Geoffrey of Monmouth asserts that at one time Ireland, Scotland, the Orkneys, Norway and Denmark acknowledged his supremacy. Whatever truth there be in this assertion, it is quite certain that he built a powerful navy whereby his name became a terror to the Vikings of the North. In his reign, however, the country was ravaged by a more direful enemy—the Yellow Plague; “whoever witnessed it, became doomed to certain death. Maelgwn himself, through Taliesin’s curse, saw the Vad Velen through the keyhole in Rhos church and died in consequence.” (Iolo MSS.)
