Ffeil 444B. - Llyfr Ieuan Lleyn, 1799,

A composite volume of poetry in strict and free metre by various poets including Mabclaf ab Llywarch, Aneirin Gwawdrwydd [sic], Evan Evans ('Ieuan Brydydd Hir'), [Robert Williams] 'Robert ab Gwilym Ddu', [David Owen] 'Dewi Wyn', [Griffith Williams] 'Gyttun Peris', [Richard Jones] 'Gwyndaf Eryri', [William Edwards] 'Gwilym Padarn', [Owen Williams] 'Owain Gwyrfai', [Evan Prichard] 'Ieuan Lleyn', [David Thomas] 'D[afydd] Ddu o Eryri', John Davies and Michael Prichard. The contents also include a list headed 'The Names of some of the most Ancient Bards and Historians and the Time wherein [sic] they Flourished'. The lettering on the spine reads 'Llyfr Ieuan Lleyn, 1799' and the volume, except for the last five folios, appears to have been written between 1799 and 1822. The last four folios are partly in the hand of D. Silvan Evans and the folio immediately preceding them is probably earlier in date than 1799 and may belong to Cwrtmawr MS 513B, Part II.
