After his death, he had a reputation as one of Europe's most successful forgers 
Morganwg was known as an Architect of the Welsh nation. This title was given for his contributions to the eighteenth-century cultural renaissance. He upheld Wales's reputation as a civil nation in Bardism and the Gorsedd of the Bards. Iolo Morganwg tried to get started some national institutions. Some of them were libraries, academies, and several museums.
The Magical White Hare of the GumpEdit
This legend or anecdotal tale is a work of Edward Williams. The work is one of the anecdotes and recollections that were included in the book entitled "RECOLLECTIONS and ANECDOTES of EDWARD WILLIAMS, THE BARD OF GLAMORGAN ; IOLO MORGANWG, B. B. D.". The book was written by Elijah Waring. The work was inspired by Chun Quoit. It was also inspired by a piece of moor land called the Gump. The moor land was between Saint Just and Pendeen in Cornwall.
The legend has it that if crossing the Gump on a moonlit night, there is a possibility that you could meet the White Hare of the Gump. If you do, then to bring good fortune, and ward off evil, you must place a silver coin under your right foot. The White Hare is a friend of the Fairy King of the Gump.
