 stated in this preface. Hence this particular group of law books may not inaptly be styled the Book of Blegywryd. Aneurin Owen adopted the Cotton MS., Titus D IX (MS. L), of the second quarter of the fourteenth century, as his representative text of this group. Dr. Gwenogfryn Evans regards the Peniarth MS. 36 A (MS. O), as the oldest now known, having been written shortly after 1282 but according to Owen 'the variations in the manuscripts of this class are but few', for which reason he is of opinion that 'they perhaps exhibit the nearest affinity to the original compilation sanctioned by Howel'. It should be noticed that the earliest of all the existing law books bearing Howel's name, viz. the Latin Peniarth MS. 28, is of the form of the Book of Blegywryd, as also the important Latin Cotton MS., Vespasian E XI, written about 1250, 1 although the name of Blegywryd is absent from both. The following passage from the preface to the Book of Blegywryd is very suggestive as to these three types of law books, and appears also to throw some light on the puzzling matter of King Howel's dominions.
