A manuscript containing the works of the medieval Welsh bards, being a transcript by William Maurice, Llansilin (see p. 492) of British Museum Addl MS 14869. Pp. 69, 119 and 141 bear respectively the dates 1September, 4 October and 6 October [16]66; however, according to an autograph statement by William Maurice at the end of Addl MS 14869 (p. 245b), he completed the transcript on 24 November 1662.
Maurice notes (pp. 473-474) that the original manuscript (now known as British Museum Addl MS 14869), from which this text was transcribed, was partly written temp. Edward II and Edward III and partly temp. Henry V. In an autograph statement on pp. 473-474 William Maurice notes that this original manuscript was once in the possession of Gruffydd Dwnn (c. 1500-c. 1570), Huw Llŷn (fl. 1532-1594) and Rhys Cain (d. 1614), and subsequently came into the possession of Robert Vaughan 'or Wengraig ger llaw Dolgellau' (i.e. Robert Vaughan, Hengwrt (1592-1667)). A later note by 'M. W[illiams]' (p. 474) dated 1728 states that this original manuscript was then at Hengwrt.
