A manuscript containing Welsh laws and pleadings. There is a pen and ink sketch of a plough on p. 105. The margins of pp. 38-95 contain index words to the subject-matter in the autograph of William Salesbury, as in Mostyn MS 159, to which pp. 123-124 belong. At the foot of pp. 123-124 there are notes in the hand of Gruffydd Dwnn. There is also an englyn attributed to Iolo Goch in the hand of William Salesbury at the top of p. 72. The contents of the remainder of this manuscript consist of excerpts, as well as some later pleadings (e.g. p. 42). At p. 123 is a fragment of the Grail, being two columns of Mostyn MS 159.
From the invocations 'Gwenoc' (pp. 76, 112), 'Gwenod : Gwnnen' (pp. 56, 110), 'Gwenoc : Gwnen : Gwinionyd' (p. 111), and 'Gwenoc : Gwnen Gwinionyd ywch kerdin' (p. 120), it is inferred that this manuscript was written in the parish of Llan Wenog, Cardiganshire, or by a native of that parish, and the text furnishes an interesting specimen of the dialectical peculiarities of south Cardiganshire. Llanwnnen is an adjoining parish to the north-east. Both Llanwenog and Llanwnnen parishes were in the upper division of the ancient lordship of Gwynionydd. Castell Gwynionydd is supposed to have been on the summit of Côd y Vôl, near Llandysul, where the river Cerdin falls into the Teifi a little north of the church. The text of pp. 1-38 corresponds practically with pp. 464-588 of the 'Dimetian Code' in vol. i of The Ancient Laws & Institutes of Wales. The text at pp. 51-56 of this manuscript corresponds to pp. 366-378 of Volume ii of The Ancient Laws & Institutes of Wales, pp. 73-74 to pp. 122-124 and 152, and pp. 96-97 to p. 342.
