The composition of the manuscript
The manuscript contains several interesting illustrations, many of them religious, including decorative letters and capital letters using the colours red and blue with a hint of green. The manuscript contains 115 folios made from parchment, and the wooden cover dates from the Middle Ages. The manuscript is fragile and a few of the folios have been repaired with stitching. As stated by Daniel Huws in The Welsh King and his Court, this is one of the few medieval Welsh manuscripts to retain a medieval, probably original binding structure.
