A composite volume containing miscellaneous material in the hand of Edward Williams ('Iolo Morganwg'). Pp. 37-146 contain an 'interleaved' copy of a Welsh chronicle recording the activities of the Welsh princes, etc., 1101-1055. This appears to be a 'variant' copy of a version of part of the Welsh chronicle known as 'Brut y Tywysogion', and, in a note at the end (p. 146), the work is linked with the name of Caradog of Llancarfan ('Ac yn yr amser yma y darfu i Garadog o Lancarvan (a fernir gan bob gwr dysgedig yn yn (sic) awdur yr hanes honn) orphen Prydieu Tywysogion Cymru o Gadwaladr hyd ei amser ef').

A composite volume containing transcripts of historical and literary material in the hand of Edward Williams ('Iolo Morganwg'). Pp. 1 -74 contain one of the two known reputed transcripts by Edward Williams of the supposedly variant version of the medieval Welsh Chronicle of the Princes ('Brut y Tywysogion') which is generally known as 'Brut Aberpergwm' or 'The Gwentian Brut'. The superscription on p. 1 reads 'Llyma Vrut y Tywysogion val y bu Ryfeloedd a gweithredoedd enseiliaid a Dialeddau, a Rhyfeddodau gwedi eu tynnu or hen gofion cadwedig au blyneddu'n Drefnedig gan Garadawc Llancarfan', and, according to a note at the end of the text (p. 74), the present copy was transcribed by Iorwerth ab Iorwerth Gwilym, i.e. Edward Williams, in 1790 from one of the manuscripts of the Reverend Thomas Richards, curate of Llangrallo [co. Glamorgan], who, in turn, had copied the work in 1764 from one of the manuscripts in the possession of George Williams, esq., of Aberpergwm [co. Glamorgan]. This is substantially the text that was published in The Myvyrian Archaiology of Wales . . ., vol. II, 1801, pp. 468-582, and also in Aneurin Owen (ed.): Brut y Tywysogion; the Gwentian Chronicle of Caradoc of Llancarvan . . . (London, 1863), this second publication being accompanied by an English translation. P. 89 is inscribed 'English Translation of Caradoc of Lancarvan's Annals of the Princes of Wales.

Other items in the volume include pp. 191-208, extracts from William Warrington: The History of Wales . . . (London, 1786); 215-19, a draft copy of the last three paragraphs of the preface to The Myvyrian Archaiology . . ., vol. II, in which the text of 'Brut Aberpergwm' was published (see G. J. Williams: op. cit., pp. 206-08); 223-5, a transcript of the opening paragraphs of a version of the Laws of Hywel Dda; and 233- 43, copies of poems by [Edward Williams] 'Iolo Morganwg'.

P. 11 (probably the 'title-page' of the section now paginated 13-100) is inscribed 'General View of the Agriculture of the County of Glamorgan, 1796', and is followed (pp. 13-100) by an incomplete essay on the said county [by Edward Williams].

A good deal of the material relating to Llanilltud is allegedly taken from an account compiled by the Reverend David Nichols, M.A., in 1729, and the whole of the contents of pp. 105-39 is presented in the form of a letter [from Edward Williams] to David Thomas, esqr., at Bath, 20 October 1798 (see IM, t. 307).

Glamorgan], to Mrs. Wyndham of Dunraven Castle relating to the writer's research work concerning the said seat and the notes he was forwarding.

The inscriptions on p. 81 and p. 83 and the note on p. 82 appear to indicate that they were intended as cover and 'title-page' respectively for a home-made booklet containing a corpus of 'englynion' by Jenkin Richards of Blaenau Gwent, co. Monmouth, extracted mainly 'o Lyfrau Harri Siôn o Bont y Pwl a Llyfr ym Meddiant Rhys Thomas, Argraffydd o'r Bont Faen ym Morganwg', but only four 'englynion', presumably meant to be attributed to this poet, follow on p. 84. Pp. 91-198 contain miscellaneous items including 91-2, notes headed 'On the oldest places of Christian Worship in Wales'; (continued)

93-7, 105-06, notes, generally derogatory, on the character and literary and metallurgical activities of Lewis Morris; 100- 04, notes on 'Welsh Ideas of Celibacy'; 122-8, a transcript of thirty 'englynion' entitled 'Ymatreg Llywelyn a Gwrnerth' attributed to Tysiliaw fab Brochwel Ysgithrawc; 130, a note relating to an 'eisteddfod' held at Y Pil (Pyle, co. Glamorgan), 1740; 131- 41, notes relating to 'singing to the harp', the 'bardd telyn', carol and 'alsain' verse, the adapting of verse to music, etc.; 147-62, transcripts of 'englynion' attributed to Rhobert, Tywysog Norddmanty, Morys Kyffin, Wm. Byrchinsha, and Gutto'r Glyn, extracts from the works of various Welsh poets, etc.; 167, a version of William Midleton's introductory epistle [to his Bardhoniaeth neu brydydhiaeth, y llyfr kyntaf (Llundain, 1593)] copied 'Ex Vol. 40. Mr. Panton' [i.e. Panton MS.40 now NLW MS 2008]; 168-9, five stanzas of a hymn tune attributed to Elis Wynn; 169, a transcript of two 'englynion' attributed to Dr. [John] Davies; 171, a list of the commotes and hundreds of Glamorgan copied from '68. P.P.' [i.e. Panton MS 68 now NLW MS 2034]; 175-88, an alphabetical list of Welsh bards 'o Lyfr D'dd Ddu o'r Eryri'; and 188-98, miscellanea including transcripts of 'englynion' attributed to Siôn Mawddwy, Ieuan Tew, William Philip, and D[afydd] ab Gwilym, miscellaneous triads, genealogical data relating to various Welsh bards and Syr Rhys ap Thomas, etc. Pp. 207-390 (previously paginated 1-184) contain a collection of maxims, proverbs, triads, sayings, etc., attributed to Cattwg Ddoeth and described on a 'title-page' to the section ( p. 199) as 'Llyma Ddoethineb Cattwg Ddoeth o Lancarvan' and in a concluding note (p. 390) as 'Llyfr y cyntaf y Gwyddfardd Cyfarwydd'. In a note on the aforementioned 'title-page' (p. 199) Edward Williams claims to have transcribed this collection in 1799 from a manuscript in the possession of Siams Thomas of Maerdy Newydd, co. Glamorgan. Preceding and following the actual text of the collection are transcripts of a prefatory letter dated 1685 (pp. 201-06) and of the concluding note already referred to (p. 390) both of which are attributed to the Glamorgan scribe and copyist Thomas ab Iefan of Tre Bryn as compiler of the manuscript from which Edward Williams was allegedly copying (see TLLM, t. 172; IM, tt. 291-4). Pp. 391-477 contain a transcript of a collection, in alphabetical order, of over three thousand Welsh proverbs attributed to Cattwg Ddoeth ('Llyma Ddiarhebion Cattwg Ddoeth . . . sef yw hwnn Ail Lyfr y Gwyddfardd Cyvarwydd'). This collection, according to the aforementioned note at the end of the preceding section (p. 390) attributed to Thomas ab Iefan, had been compiled by the said Thomas from various sources and formed a continuation of the previous section. Edward Williams's claim with regard to the Siams Thomas volume is probably intended to apply to the contents of pp. 391-477 as well. The contents of pp. 199-390 have been published in The Myvyrian Archaiology of Wales . . ., vol. III (London, 1807), pp. 1-99.

A composite volume consisting of a number of home-made booklets containing miscellaneous items in the hand of Edward Williams ('Iolo Morganwg') bound together.

According to an end note (p. 52) the treatise was copied 'O Lyfr Mr. Richards o Langrallo', but for the opinion that it was compiled by Edward Williams himself and attributed to Walter Map see TLLM, t. 3. P. 53 contains a note, allegedly taken from Thomas Truman of Pant Lliwydd's book of pedigrees, linking Walter Map and his family with the village of Trewallter and parish of Llancarfan, co. Glamorgan, but for the falsity of this claim which is probably an Edward Williams forgery see again TLLM, t. 3. Pp. 54-68 contain a further treatise in Welsh on agricultural husbandry with the superscription 'Cyngor yr Hen Gyrys Megis yr oedd ynteu yn cynghori ei fab fal hynn'. This, according to a note on p. 68, was copied from a volume in the possession of the Reverend Thomas Evans of Brechfa in 1800. For the connection between this and the treatise on agriculture which is to be found in the 'Red Book of Hergest' and which was published in The Bulletin of the Board of Celtic Studies, vol. II, pp. 8-16, see TLLM, t. 3.

Pp. 233-300 form a booklet inscribed on the outer, upper cover (p. 233) '1808 Prydyddiaeth Cymmysg Iolo Morganwg' and containing (pp. 235-57) free- and strict-metre Welsh poems by [Edward Williams] 'Iolo Morganwg' himself.
