The Book of Llandaff is bound in thick, square edged oak boards with sunken centre panels. The lower board, which is probably the twelfth-century original, bears evidence of having been covered in a thin layer of silver and is all that remains of the earliest binding. The gilt-bronze figure of Christ in Majesty that adorned the lower cover was a mid-thirteenth century addition which has, since 1981, been kept separate from the volume in its own box. Fragments of the thin silver plate are preserved along with the figure and nail holes in the board indicate that had once been completely covered. The outline of a mandorla with associated holes in the sunken panel suggest that an earlier ornament was attached to it.
