Edward Williams (1747-1826); an antiquarian, poet and collector of medieval Welsh literature, invented Coelbren y Beirdd or The Bardic Alphabet in about 1791 and claimed that it was the alphabet of the old Welsh bards; In 1840 Taliesin ab Iolo, Iolo Morganwg's son, published a book entitled Coelbren y Beirdd and based on his father's writings which included details of the Bardic Alphabet; the alphabet proved popular with poets and druids during the 19th century, but some, such as Edward Davies (1756-1831), questioned it's authenticity; by 1893 few believed that it was genuine, and it was revealed that Morganwg had forged many of his manuscripts)
