The Myvyrian Archaiology of Wales is a printed collection of medieval Welsh literature, published in three volumes by the Gwyneddigion Society between 1801 and 1807. Until John Gwenogvryn Evans produced diplomatic editions of the important medieval Welsh manuscripts, the Myvyrian Archaiology provided the source text for many translators of medieval Welsh material. It was founded, and funded, by Owen Jones, who engaged William Owen Pughe as editor, and Edward Williams, better known as Iolo Morganwg, to search Wales for manuscripts.
