An imperfect manuscript consisting of thirty folios of uniform size and two smaller leaves, with the two halves of ? the lower cover of an early nineteenth century periodical or part publication, which at one time seems to have served as a protective covering, bound in at the beginning. A considerable part of the original manuscript appears to have been lost as the volume was described by the Reverend John Williams ('Ab Ithel'), circa 1856, as containing 'about 100 pages' (see L. James: Hopkiniaid Morganwg . . . (Bangor, 1909), p. 91). The former protective cover bears the inscription 'Llyfr Llanfihangel Iorwerth. Cywyddau amrafaelion. Siôn Cent hyd Dafydd Hopcin o'r Coetty. Englynion Eiry Mynydd, &c.', in the hand of Edward Williams ('Iolo Morganwg'), and the contents consist of transcripts of Welsh verse mainly in strict metre. Dafydd Hopkin of Coety, co. Glamorgan is sometimes named as the copyist (see L. James: op. cit., p. 91; TLLM, tt. 229, 267; and IMCY, t. 139). The poems include 'cywyddau' and 'englynion' by Thomas Prys, Ieuan Tew Brydydd, Dafydd Hopkin (1734), Ieuan Brechfa, Lewis Morganwg, Iorwerth Fynglwyd, Dafydd ap Gwilym, Rys Dynfwal (sic), Rhys ab Morys, ?Mredydd ap Rees, Swrdwal Hen, Huw Dafydd Probert, Siôn Tudur, Owain Gwynedd, Gwilim ap Ieuan Hen, Dafydd ap Edmwnt, Daio Lliwiell, Ieuan Tew Brydydd Ifangc, Huw Lewis, Gruffydd ab Ifan ab Llewelyn Fychan, Wiliam Cynwal, Morus ab Hywel ab Tudur, Siôn Cent, Hywel ab D'd ab Ieuan ab Rhys, Llywelyn Goch, Gruffydd Dafydd Fychan, Ieuan ab Hywel Swrdwal, Bleddyn Fardd, and Dafydd Llwyd Fach, a series of pseudo- gnomic poems with each stanza commencing with the words 'Eira mynydd' some of which are attributed to Llywarch Hen and Mabclaf ab Llywarch, and poems attributed to Taliesin and Aneurin. There are marginal notes by Edward Williams and his son Taliesin Williams.

A composite volume containing miscellaneous historical and literary material in the hand of Edward Williams ('Iolo Morganwg'). Pp. 24-36 contain a transcript of a version of the medieval Welsh Chronicle of the Princes associated with the name of the fifteenth century poet and genealogist Ieuan Brechfa with the title or superscription 'Brut y Tywysogion . . . a dynnwyd o Lyfrau Caradawc Llancarfan ac eraill o hen Lyfrau Cyfarwyddyd a ysgrifenodd Ieuan Brechfa'.

II, 1801, pp. 470-565 (bottom section of pages). Pp. 37-135 contain one of the two known reputed transcripts by Edward Williams of the allegedly variant version of the aforesaid Welsh Chronicle of the Princes known as 'Brut Aberpergwm' or the 'Gwentian Brut'. The title or superscription reads 'Llyma Vrut y Tywysogion val y bu Ryfeloedd a Gweithredoedd enseiliaid a Dialeddau a Rhyfeddodau gwedi eu tynnu o'r hen gofion cadwedig a'u blynyddu'n drefnedig gan Garadawc Llancarfan', and the text was reputedly transcribed by [Edward Williams] 'Iorwerth Gwilym' in 1790 from one of the manuscripts of the Reverend Thomas Richards, curate of Llangrallo [co. Glamorgan], who, in turn, had reputedly copied the work in 1764 from a manuscript in the possession of George Wiliams of Aber Pergwm [co. Glamorgan] (see p. 135).
