The use of bookshrines in Ireland was very possibly the survival of an early custom of the primitive Church. It seems to have been applied chiefly, if not always, to books too precious or sacred to be read. We are told that a Psalter belonging to the O'Donels was fastened up in a case that was not to be opened; and were it ever unclosed, deaths and disasters would ensue to the clan. If borne by a priest of unblemished character thrice round their troops before a battle, it was believed to have the power of granting them victory, provided their cause were a righteous one. Cumhdachs were also used in Scotland, but no Scottish examples have survived. The oldest cumhdach now existing is one in the Museum of the Royal Irish Academy, which was made for the MS. known as Molaise's Gospels, at the beginning of the eleventh century. It is of bronze, and ornamented with silver plates bearing gilt patterns. Another book-shrine, made for the Stowe Missal a little later, is of oak, covered with silver plates, and decorated with a large oval crystal in the middle of one side. The Book of Kells once had a golden cumhdach, we are told, or, more correctly, perhaps, a cumhdach covered with gold plates; but when the book was stolen from the church of Kells in 1006 it was despoiled of its costly case, with which the robbers made off, leaving the most precious part of their booty, the book itself, lying on the ground hidden by a sod. One of the earliest bookbinders in this country was a bishop, Ethilwold of Lindisfarne, who bound the great Book of the Gospels that his predecessor Eadfrid had written. For the same book Billfrið the anchorite made a beautiful metal cover, gilded and bejewelled. The Lindisfarne Gospels still exists, but the cover which now contains it, though costly, is quite new. Like most ancient book covers the original one has been lost, or destroyed for the sake of its valuable material. Among the earlier mediæval bindings those of the Byzantine school of art rank very high. They were exceedingly splendid, for gold was their prevailing feature, and jewels and enamel were also lavished upon them. The ordinary books of the middle ages were usually bound in substantial oak boards covered with leather, and often having clasps, corners, and protecting bosses of metal. In the twelfth century the English leather bindings produced at London, Winchester, Durham and other centres, were pre-eminent. Miss Prideaux instances some books which were bound for Bishop Pudsey, and which are now in the cathedral library of Durham, as "perhaps the finest monuments of this class of work in existence." The sides of these volumes are blind-tooled; that is, the designs are impressed by means of dies or tools with various patterns and representations of men and of fabulous creatures, but not gilded.
