The Myvyrian archaiology of Wales: collected out of ancient manuscripts.

This monumental publication consisted of early Welsh poetry and Brutiau, or Chronicles. It was published in three volumes, two in 1801, and the other in 1807. To many scholars, these publications symbolise the end of the Welsh language manuscript era. Owain Myfyr and William Owen Pughe were mostly responsible for bringing these volumes into print; they were also assisted by Iolo Morganwg in the process of compiling their content. It must be noted that Myfyr’s fellow-contributors were eager to name the publication after him as he made extraordinary financial contributions to the enterprise, an estimated four to five thousand pounds. Iolo travelled the length and breadth of Wales in search of materials which Pughe structured and prepared for press. Unfortunately, the venture was not entirely a success and they faced minor difficulties with the transcription process. In addition, the inclusion of Iolo Morganwg’s infamous forgeries didn’t do the publication any justice in terms of later circulation and sales.
